EXECUTIVE SUMMARY
 

Sampling Episode Report for Island Princess
 

This Sampling Episode Report describes the sampling and analysis activities to 

characterize wastewater (graywater and sewage) generated and discharged by the cruise vessel 

Island Princess while in Alaska waters. This sampling took place from August 28 through 

September 2, 2004, under the direction of the U.S. Environmental Protection Agency (EPA). 

The sampling program is part of EPA's data collection effort to evaluate whether to develop 

wastewater discharge standards, under 33 USC 1901 Note, for cruise vessels authorized to carry 

500 or more passengers for hire when operating in the waters of the Alexander Archipelago or 

the navigable waters of the United States within the State of Alaska or within the Kachemak Bay 

National Estuarine Research Reserve. EPA will use information from the sampling of this vessel 

and three other cruise ships in Alaska to characterize wastewater generated and discharged by 

large cruise vessels with advanced wastewater treatment systems. 

EPA selected the Island Princess to characterize the performance of the 

Hamworthy KSE Ltd. membrane bioreactor treatment system, a wastewater treatment system 

that uses aerobic biological oxidation followed by ultrafiltration and ultraviolet disinfection. 

Samples were collected of various graywater sources (galley, laundry, accommodations, and 

food pulper wastewater); influent to the treatment system (mixed accommodations wastewater 

and sewage); influent to UV disinfection component of the treatment system; effluent from the 

treatment system; source water; wastewater treatment residuals (screening solids and wastewater 

biosludge); and incinerator ash. Most wastewater samples were collected for five consecutive 

24-hour sampling periods; food pulper wastewater, treatment residuals, and incinerator ash were 

collected for a single 24-hour sampling period. 

Strap-on ultrasonic flow meters were installed near the sampling locations for the 

galley wastewater, accommodations wastewater, influent to treatment, and effluent from 

treatment to collect flow data and to trigger automatic sampling machines. 

vi 
Various sample collection methods (composite by flow, composite by time, grab, 

and grab composite) were used depending on the sampling point and analyte. Tested analytes 

included pathogen indicators (fecal coliform, E.coli, and enterococci), classical pollutants, total 

and dissolved metals, volatile and semivolatile organics, pesticides, polychlorinated biphenyls, 

and dioxins and furans. Not all samples were analyzed for all target analytes. 

The galley wastewater samples showed the largest number of analytes detected 

among graywater sources and the highest concentrations of several analytes commonly used to 

measure wastewater strength: all three pathogen indicators, biochemical oxygen demand 

(BOD5), chemical oxygen demand (COD), hexane extractable material (HEM), silica-gel hexane 

extractable material (SGT-HEM), and total suspended solids (TSS). Laundry wastewater 

samples had the highest concentration among graywater sources for six analytes, while 

accommodations wastewater had the highest concentration for five analytes. 

Because of water conservation measures onboard cruise ships (such as vacuum 

toilets), key analytes such as pathogen indicators, BOD5, COD, and TSS are found at much 

higher concentrations in the influent to the Island Princess wastewater treatment system than in 

typical domestic wastewater. Of the 54 metal analytes tested for, 27 were detected in every 

influent to treatment system sample. Among the 203 target analytes for volatile and semivolatile 

organics and pesticides, only 6 were detected in any Island Princess influent to treatment samples, 

most at concentrations close to their detection limits. Among the 160 polychlorinated biphenyl 

(PCBs) analytes tested for, 36 were detected in Island Princess influent to treatment samples. 

The Island Princess' Hamworthy wastewater treatment system treats only 

accommodations wastewater and sewage. The system successfully removed almost all pathogen 

indicators (>99%) and most classical pollutants, metals, and organics. Fecal coliform, a 

pathogen indicator, was detected in only 1 of the 15 effluent from treatment samples, while 

enterococci and E. coli were each detected in 3 of 15 effluent samples at concentrations close to 

their detection limits. The treatment system removed almost all BOD5 (99%), COD (93%), TOC 

(89%), settleable residue ( >99%) and TSS (99%). The treatment system reduced ammonia by 

58%, total Kjeldahl nitrogen (TKN, which measures both ammonia and organic forms of 

vii 
nitrogen) and total phosphorus by approximately 75%, while nitrate/nitrite levels remained 

relatively unchanged. The treatment system was highly efficient at removing particulate metals, 

and removed dissolved metals at an average of 37%. The treatment system removed most of the 

volatile and semivolatile organics to concentrations below detection levels. 

The Hamworthy wastewater treatment system generates two types of residual 

waste: screening solids (from the two screen presses at the beginning of the treatment system) 

and waste biosludge (excess biological mass from the treatment system’s bioreactor). Screening 

solids are collected and incinerated onboard. Waste biosludge is pumped to a double-bottom 

holding tank for overboard discharge outside of 12 nautical miles from shore. Most of the 

analytes detected in the waste biosludge were also detected in the influent to the treatment 

system. For many analytes, concentrations in the screening solids and waste biosludge exceeded 

those in the influent to treatment, suggesting that these analytes are removed from the system in 

these waste streams. 

On average, each person generated approximately 41 gallons of treated 

accommodations and sewage wastewater per person per day.

1.0 INTRODUCTION

This Sampling Episode Report describes the Environmental Protection Agency’s 

sampling and analysis activities to characterize graywater and sewage generation and treatment 

by Princess Cruises’ cruise ship Island Princess (Island) while in Alaska waters. This sampling 

took place from August 28 through September 4, 2004, under the direction of the Engineering 

and Analysis Division of the Office of Science and Technology, and the Oceans and Coastal 

Protection Division of the Office of Wetlands, Oceans, and Watersheds of the U.S. 

Environmental Protection Agency (EPA). 

The Island is a 88,000 gross ton cruise vessel launched in 2003. The vessel has 

16 decks, a length of 964 feet, and a beam of 106 feet. The Island’s maximum cruising speed is 

24 knots. Its port of registry is Bermuda. During the sampling episode, the Island carried 2,019 

passengers and 906 crew. The ship’s itinerary was as follows: 

Date Port

August 28, 2004 Whittier, AK 

August 29, 2004 Cruising College Fjord 

August 30, 2004 Cruising Glacier Bay 

August 31, 2004 Skagway, Alaska 

September 1, 2004 Juneau, Alaska 

September 2, 2004 Ketchikan, Alaska 

September 3, 2004 Cruising Inside Passage 

September 4, 2004 Vancouver, B.C. 

This sampling program is a part of EPA’s data collection effort to evaluate 

whether to develop wastewater discharge regulations for cruise vessels authorized to carry 500 

or more passengers for hire when operating in the waters of the Alexander Archipelago or the 

navigable waters of the United States within the State of Alaska or within the Kachemak Bay 

Estuarine Research Reserve (hereafter referred to as Alaska waters). Such regulations are 

authorized by “Title XIV - Certain Alaskan Cruise Ship Operations” of the Miscellaneous 

Appropriations Bill (H.R. 5666) passed by Congress on December 21, 2000, in the Consolidated 

1-1
Appropriations Act of 2001 (Pub L. 106-554, Sections 1401-1414, 33 USC 1901 Note). The 

data and information gathered through this sampling episode were collected using EPA's 

authority under section 308 of the Clean Water Act, as also provided by Title XIV. Princess 

Cruise Lines voluntarily provided information and data gathered for and represented in this 

report, notwithstanding the above cited authority, in the interest of research for the improvement 

of wastewater treatment standards. 

EPA selected the Island to characterize the performance of the Hamworthy KSE 

Ltd. (Dorset, England) membrane wastewater bioreactor treatment system (Hamworthy 

treatment system), an advanced wastewater treatment system that uses aerobic biological 

oxidation followed by ultrafiltration and ultraviolet (UV) disinfection. EPA will use the 

analytical and flow data included in this sampling episode report to evaluate the performance of 

the Hamworthy treatment system, and to analyze patterns and variability in wastewater sources.

 Samples were collected in accordance with with procedures specified in the 

Generic Sampling Plan for Large Cruise Ships in Alaska Waters (Generic SAP) and the 

ship-specific Sampling and Analysis Plan for the Island Princess (Island SAP). The Island SAP 

is presented in Appendix E and the Generic SAP is available on EPA’s website at 

http://www.epa.gov/owow/oceans/cruise_ships/GenericSAP040602.pdf. Pathogen indicator 

analyses were performed onboard. Samples for all other analyses were shipped to shoreside 

EPA-contract laboratories for analysis. Appendix D identifies all EPA-contract laboratories used 

in this sampling episode. 

Section 2.0 of this report describes the generation, collection, and treatment of 

graywater and sewage on the Island, as well as the sampling point and flow meter locations used 

in this sampling episode. Section 3.0 describes the sample collection methods and deviations 

from the Island SAP. Section 4.0 presents and analyzes the analytical, flow, and shipboard data 

collected during the sampling episode. Section 5.0 describes the quality assurance and quality 

control (QA/QC) procedures and results. Section 6.0 presents references used in this document. 

Tables and figures referred to in the text are located at the end of each section.

2.0 WASTEWATER SYSTEM AND SAMPLING POINTS 

This section describes graywater and sewage generation, collection, and treatment 

on the Island, as well as the sample collection points and flow meter locations and installation 

points used in this sampling episode. 

2.1 Wastewater Generation and Collection 

The ship’s collection, holding, and transfer system (CHT) collects and transfers 

graywater and sewage generated onboard to the ship’s Hamworthy treatment system or to 

overboard discharge. For the purpose of this report, graywater refers to non-sewage wastewaters 

that are collected by the CHT system. The CHT system is composed of five subsystems, referred 

to by the ship’s crew as the galley, food pulper, accommodations, laundry, and sewage systems. 

Figure 2-1 is a simplified diagram of the Island’s graywater and sewage CHT system. 

Wastewater sources collected by each of the five subsystems are described in Table 2-1. The 

Hamworthy treatment system treats only accommodations wastewater and sewage. The other 

wastewaters are stored in double-bottom holding tanks untreated and discharged overboard 

outside of 12 nautical miles (nm). 

Potable water is used as source water for all ship operations that generate 

graywater and sewage (e.g., laundry, galley, food pulper, sinks, showers, and toilets). Potable 

water is produced onboard and bunkered while in port, with produced water providing 

approximately two-thirds of freshwater requirements and bunkered water providing 

approximately one-third of fresh water requirements. 

2.2 Wastewater Treatment 

The Island is outfitted with a Hamworthy treatment system, an advanced 

treatment system that uses aerobic biological treatment followed by ultrafiltration and ultraviolet 

(UV) disinfection. Figure 2-2 provides a simplified diagram of the Hamworthy treatment 

system. This system treats only accommodations wastewater and sewage onboard the Island. 

2-1
 
Wastewater from the accommodations CHT system culminates in two holding 

tanks, which are pumped to two wastewater buffer tanks, the first component of the Hamworthy 

treatment system. Air is added via blowers to aerate the buffer tanks. The sewage CHT system 

culminates in four sewage collection tanks. Accommodations wastewater from the buffer tanks 

and sewage from the storage collection tanks mixes in a common line and then splits for 

treatment through two parallel treatment trains. The first unit of the treatment trains are selfcleaning screen presses (mesh size 400 μm) to remove paper and other coarse solids. Next, the 

wastewater is pumped to the first stage aerated bioreactors, then to interstage bag filters (mesh 

size 200 μm) and filtrate tanks, and finally to the second stage aerated bioreactors. Mixed liquor 

(wastewater containing organic matter and biological floc) overflows from the second stage 

bioreactors back to the first stage bioreactors. Bioreactor aeration is provided by fine bubble 

diffusers at the bottoms of the bioreactors. 

From the second stage bioreactors, the wastewater is pumped through the 

membrane filters (ultrafiltration, pore size 40 nm) and collects into permeate tanks. The 

membrane filters use cross flow design (wastewater flows parallel to membrane surface) to 

minimize fouling. Membrane concentrate, consisting of particulate matter and mixed liquor, is 

returned to the second stage bioreactors. Approximately once every two weeks, the treatment 

trains are taken offline for approximately 1.5 hours to disinfect the membrane filters using 

sodium hypochlorite; the sodium hypochlorite solution remains in the system. (When one 

treatment train is being disinfected, all wastewater is diverted to the second, parallel treatment 

train.) In the final stage of treatment, the combined wastewater from the two permeate tanks 

undergoes UV disinfection. The hydraulic residence time of the treatment system (i.e., the 

amount of time the wastewater stays in the treatment system) is less than one day. 

According to the ship’s crew, the Hamworthy system can treat 600 m3 (159,000 

gallons) per day of sewage and accommodations wastewater generated onboard, well in excess 

of its typical daily load, approximately 450 m3 (119,000 gallons) as determined by interviews 

with the ship’s crew and measured flows collected during the sampling episode. 

2-2
 
The Hamworthy treatment system operates continuously, regardless of the ship’s 

location (e.g., in port, at sea within Alaska waters, at sea outside Alaska waters). The vessel 

typically continuously discharges treated wastewater from this system overboard. Where 

overboard discharge is prohibited, such as in Glacier Bay National Park, treated wastewater is 

diverted to storage in double-bottom holding tanks and held for eventual discharge overboard 

outside 12 nautical miles (nm) from shore. 

Treated wastewater is recycled back to the treatment system when effluent total 

suspended solids concentrations exceed 27 mg/L (determined based on a correlation to measured 

effluent turbidity) to ensure that inadequately treated wastewater is not discharged. 

The Hamworthy system generates three types of residual waste: screening solids 

(from the screen presses), spent bag filters (from the interstage bag filters), and waste biosludge 

(excess biological mass from the second stage bioreactors). The screening solids (50 

kilograms/day) drop from the dry waste outlets of the screen presses and collect into plastic bags. 

The bag filters are replaced every 200 hours of operation. The plastic bags containing both 

screening solids and spent bag filters are manually fed to the onboard incinerator via a small 

chute. Incinerator ash is disposed of on shore as a non-hazardous waste. 

Approximately 10 metric tons of waste biosludge are removed from the second 

stage bioreactors each week to maintain bioreactor total suspended solids (mixed liquor 

suspended solids (MLSS)) concentrations at approximately 20,000 mg/L. The biosludge is not 

dewatered and is immediately discharged overboard (i.e., it is not discharged to holding tanks); 

therefore, biosludge is wasted only when the vessel is greater than 12 nm from shore. 

The Hamworthy treatment system includes a total of 48 membrane modules, 

arranged in four groups of four sets of three. At any given time, only two of the three membrane 

modules in each set are operated; the third membrane module in each set is a backup module. 

One membrane module is cleaned each day, so the membrane cleaning cycle repeats every 48 

days. The cleaning process uses “Membrane Cleaner Part 1" and “Membrane Cleaner Part 2" 

2-3
 
2.3 

and clean water, and requires a total of eight hours. The nonhazardous wash wastewater is 

collected in a double-bottom holding tank and discharged at sea outside of 12 nm. 

Wastewater flow through the treatment system is controlled by the 

accommodations wastewater and sewage pumps. However, during periods of reduced treatment 

capacity (e.g., maintenance), seven double-bottom holding tanks provide a holding capacity of 

822 m3. The contents of these holding tanks can either be pumped to the wastewater treatment 

system or held for discharge without treatment outside 12 nm from shore. 

Wastewater and Residual Sample Collection Points 

Samples were taken from the graywater sources (galley, laundry, and 

accommodations); influent to the treatment system (combined accommodations wastewater and 

sewage); influent to the UV disinfection portion of the treatment system; effluent from the 

treatment system; source water (water from the ship’s potable water system); wastewater 

treatment residuals; and incinerator ash. Table 2-1 describes the wastewaters sampled, their 

sampling point locations, their flow meter locations (if applicable), and the number of days they 

were sampled. Table 2-2 provides the same information for the treatment residuals and 

incinerator ash sampled. In general, food pulper and wastewater treatment residual samples 

were taken for one 24-hour period, while samples of accommodations, galley, and laundry 

wastewater and the influent to and effluent from the treatment system were taken for five 24­

hour periods. See Section 3.2 and Table 3-2 for information on the analytes tested. Note that 

samples were also collected of galley, laundry, and food pulper wastewaters as they were 

discharged untreated from a double-bottom holding tank. 

Samples were collected from the ship’s potable water system (source water) to 

determine if any of the target analytes were present as background contamination. One trip 

blank was prepared and analyzed for volatile organics to evaluate possible contamination during 

shipment and handling of samples. Finally, an equipment blank was prepared and analyzed to 

evaluate possible contamination caused by the sampling equipment. 

2-4
 
2.4 

Samples were not taken directly from the sewage CHT system. In addition, 

samples could not be collected of wastewater held in double-bottom holding tanks for discharge 

outside 12 nm from shore (i.e., treated effluent diverted to storage while the ship cruised Glacier 

Bay) because (1) double-bottom holding tanks cannot be accessed directly due to safety 

considerations, and (2) sampling from the holding tank discharge manifold would characterize 

combined holding tank discharges and not discharges specific to the holding tanks of interest. 

Flow Meter Locations 

Strap-on flow meters (Controlotron Model 1010) were installed at four sampling 

locations to collect flow data and to control automatic composite sample machines (by triggering 

sample collection after a defined amount of flow passed through the pipe). The first flow meter 

location was on the outlet pipe from the crew galley wastewater collection tank (galley 

wastewater, SP-1; see Table 2-1 for a description of wastewaters and Figure 2-1 for a simplified 

graywater and sewage CHT system diagram showing sampling points and flow meter locations). 

The second location was on the outlet pipe from one of the eleven accommodations collection 

tanks (accommodations wastewater, SP-3; see Table 2-1 and Figure 2-1). The third location was 

at the influent to the wastewater treatment system on the combined wastewater inlet pipe to the 

screen presses (SP-4; see Table 2-1 and Figure 2-2). The final location was at the effluent from 

the treatment system (on the overboard discharge line for the treated effluent, SP-6/7; see Table 

2-1 and Figure 2-2). 

The sampling point for laundry wastewater was located on piping that would not 

support installation of a strap-on flow meter (see Table 2-1), precluding collection of flow data 

and flow-weighted composite samples at this sampling point. Time-weighted composite samples 

were collected at the laundry wastewater sampling point (see Table 3-1 for a description of the 

sample collection method). Flow estimates for the food pulper wastewater were provided by the 

ship’s crew.

3.0 SAMPLE COLLECTION METHODOLOGY 

This section describes the sample collection and analysis methods and deviations 

from the ship-specific Sampling and Analysis Plan for Island Princess (Island SAP; Appendix 

E). A more detailed explanation of the sampling methodologies, analytes and analytical 

methods, sampling frequency and duration, schedule, and logistics that were followed during the 

sampling onboard the Island can be found in Section 3.0 of the Island SAP. 

3.1 Pre-Sampling Activities 

EPA performed an engineering ship visit to the Island on March 25, 2004. The 

Island SAP was prepared based on information colleted during that ship visit and from subsequent 

follow-up communication with Princess personnel. One week prior to the sampling episode, 

personnel conducted sampling setup activities onboard the Island, including loading sampling 

equipment and the onboard laboratory, inspecting the installed sampling ports, installing the 

strap-on ultrasonic flow meters, and installing and programming the automatic sampling 

machines. 

3.2 Sample Collection and Analysis Methodology 

In general, samples of laundry, galley, and accommodations wastewater and 

influent to and effluent from the treatment system were taken for five consecutive 24-hour 

periods, while wastewater treatment residual samples were taken for one 24-hour period (see 

Tables 2-1 and 2-2). System piping precluded collection of samples of food pulper wastewater 

as generated. 

Laundry, galley, and food pulper wastewaters are stored in holding tanks for 2 to 

5 days before being discharged untreated outside of 12nm from shore. One-time grab samples of 

these wastewaters were collected, primarily to determine their pathogen indicators counts. 

Because the onboard pathogen indicators laboratory was not yet operating at the time of sample 

3-1
 
collection, pathogen indicator analyses for these samples were performed approximately 18 

hours outside the required 6-hour holding time; the resulting data are not considered valid. 

However, other analytes were also analyzed for; results are presented in Appendix A-2. 

Various sample collection methods (described in Table 3-1) were used depending 

on the waste stream and analyte (see Table 3-2). Most samples were composited over each 24­

hour sampling period or were single grab samples in a 24-hour period. However, multiple (1 to 

3) grab samples per 24-hour period were collected for pathogen indicator analyses because these 

samples must be analyzed within 6 hours of collection (see Table 3-2). Table 3-3 describes the 

analyte groups and lists the analytical methods used. 

Each time a grab or grab composite sample was taken, another separate sample 

was placed in a separate container to perform field measurements of pH, temperature, 

conductivity, salinity, turbidity, sulfide, and free and total chlorine onboard. Temperature and 

pH were measured immediately at the sampling point, and the remaining parameters were 

measured at the sample staging area onboard. See Table 3-4 for equipment used for these 

measurements. Field measurements are used primarily to determine sample preservation 

requirements. Samples (other than those used for field measurements) were preserved in 

accordance with procedures described in the Island SAP (Appendix E), with exceptions as noted 

in Section 3.6 and Table 3-5. Note that while Alaska and Federal regulations for cruise ship 

discharges include standards for total residual chlorine, the equipment used to measure residual 

chlorine onboard was not suitable for measuring low levels of chlorine (detection limit of 20 

μg/L compared to a standard of 10 μg/L) and was subject to various interferences, such as from 

oxidized forms of manganese. Accordingly, the field measurements collected during this 

sampling episode should not be used to assess compliance with cruise ship discharge standards. 

Flow data were collected from the strap-on flow meters installed by the sampling 

team. See Section 2.4 for descriptions of the flow meter locations and Figures 2-1 and 2-2 for 

their locations. The flow meters were programmed to record the instantaneous flow rate 

(m3

/min) and total flow (m3) every five minutes. 

3-2
 
3.3 Converting Solids Mass Units to Volume Units 

The screening solids samples had high solids contents; therefore, the results for 

classical pollutants, metals, and volatile and semivolatile organics were reported by the 

laboratories in mass units. To allow for direct comparison of these results to those of other 

wastewater samples, mass units for this sample were converted to volume units using the 

following equation and assuming a sample density of 1: 

Amount (mass units) * (% solids/100) = Amount (volume units) 

All data in this report pertaining to the screening solids sample are reported in 

volume units. The laboratory data packages, which are included in the Cruise Ship Rulemaking 

Record and available upon request, contain the original mass units results reported by the 

laboratories. Note that the analytical results for the incinerator ash sample were also reported in 

mass units. However, the incinerator ash results were not converted because the sample was 

>90% solids. 

3.4 Quality Assurance/Quality Control 

Duplicate samples were collected for quality assurance and quality control. 

Results for duplicate samples were averaged. See Section 5.2.3 and Tables 5-3 and 5-4 for 

details on duplicate sampling. Other field quality control samples prepared for this sampling 

episode include a trip blank and an equipment blanks, which are discussed in Sections 5.2.1 and 

5.2.2, respectively. 

3.5 Interview with the Ship’s Crew 

The ship’s crew was interviewed to obtain information regarding activities that 

impact wastewater generation. See Appendix C for details on these interviews and Section 4.2 

for a summary. 

3-3
 
3.6 Deviations from the Sampling and Analysis Plan 

The sampling episode proceeded as specified in the Island SAP with the 

deviations described in Table 3-5. 

3-4

Sample Collection Method Description 

Composite by Flow Flow-weighted composite samples were collected using an automatic sampling machine interfaced with 

ultrasonic flow meter (see Section 2.4). The flow meter signaled the automatic sampling machine to coaliquot each time a fixed quantity of wastewater passed through the wastewater pipe. The number of ccollected per 24-hour sampling period ranged from approximately 30 to 60, depending on the total volufor the planned analyses each sampling day. Sample aliquots were collected into a 10-L sample composampling machine. At the end of each 24-hour period, the sample composite jar(s) were mixed and pousample bottles for analysis. Samples collected using the composite-by-flow method best represent a wthrough a pipe. 

Composite by Time Time-weighted composite samples were collected using an automatic sampling machine programmed t

aliquots at fixed time intervals. The programmed time interval differed by sampling point (see Table 3composite sample aliquots collected per 24-hour sampling period ranged from approximately 30 to 40, volume of sample required for planned analyses. Sample aliquots were collected into a 10-L composite sampling machine. At the end of the 24-hour sampling period, the sample composite jar(s) were mixed individual sample bottles for analysis. The composite-by-time method was used when composite-by-flfeasible. 

Grab Grab samples were discrete samples collected directly into the sample bottles from the sample tap or th

connected to the sample tap. Note that samples for pathogen indicator analyses were collected as grab 

composite sample ) because they must be analyzed within a 6-hour holding time. 

Grab composite Samples (1 to 4 per 24-hour sampling period) were manually collected as grab samples but composited 

the laboratory for a single analysis. The grab composite method was used when composite-by-flow or methods were not appropriate. Volatile organics – grab samples were collected directly into sample vials, which were filled completeanalytes by volatilization. Grab samples for each 24-hour period for analysis of volatile organics were laboratory for a single analysis. Total and available cyanide – grab samples were chemically preserved as soon as possible to minimizThe preserved total and available cyanide grab samples for each 24-hour period were composited onbofor a single analysis. Hexane-extractable material/silica-gel treated hexane-extractable material (HEM/SGT-HEM)– gcollected directly into sample containers to avoid loss of HEM/SGT-HEM that might adhere to the intesampling container (e.g., sample composite jar). The sampling team prepared composite HEM/SGT-HEa single analysis per sampling point per day by filling approximately one-fourth (250-mL) of the samplcollected each grab sample, resulting in 1-liter of sample in each container at the end of each sampling

Deviation Description 

Pathogen Indicators Laboratory Duplicates 

For 5% of the pathogen indicators samples, duplicate 100-mL sample volumes were taken with the intewould composite the 100-mL sample volumes and then analyze duplicate samples from each compositlaboratory precision (i.e., laboratory duplicates). However, the laboratory did not prepare composites, b

of the 100-mL sample volumes individually. Accordingly, the results obtained from these analyses are not laboratory duplicates, and are presented and handled as such in this report. See Section 5.2.3 and Tduplicate sampling for pathogen indicators. 

Laundry Wastewater (SP-2), Composite Samples 

The strap-on flow meter set-up and calibration was unsuccessful at the laundry wastewater sampling polaundry wastewater holding tank), most likely due to poor pipe flow conditions such as pipe scaling or result, flow data could not be collected at this sampling point. In addition, the flow meter could not be collection of flow-weighted composite samples at SP-2 as described in the Island SAP. As an alternatimethodology, the automatic sampling machine was programmed to collect a time-weighted composite Table 3-2. EPA conclude that the collected samples were respresentive of laundry wastewater as gener

the Island. 

Laundry Wastewater (SP-2), Grab Samples 

The sampling team successfully collected only one set of four planned grab and grab composite sampledue to the inability to coordinate sample collection times with adequate wastewater volumes in the launSample volume from the single grab was sufficient for analysis of pathogen indicators, volatile organic

was not sufficient for analysis of HEM/SGT-HEM and available cyanide. 

Effluent from Treatment (SP-6/7), Composite and Grab Samples 

Composite by flow sampling at SP-6/7 was suspended on Day 3 from 0720 to 2115 because overboard while the ship cruise Glacier Bay. (The flow meter that controlled composite by flow sample collectiooverboard discharge pipe, but during this time the effluent was diverted to storage in double-bottom hograb and grab composite sample collection times were adjusted to account for the suspended discharge also located downstream of valve that diverts the treated effluent to the double-bottom holding tanks.

Volatile Organics Preservation 

Free chlorine was detected in pre-sampling field tests at all sampling points. Based on these results, thprepreserved all volatile organics sample vials with sodium thiosulfate rather than waiting to determine requirements based on the free chlorine field test results. Free chlorine was generally detected in grab throughout the sampling episode. (Sample vials were also prepreserved with hydrochloric acid to contdiscussed in the Island SAP.)

Deviation Description 

Galley, Laundry, and Food Pulper Overboard Discharge (SP-8, SP-9, SP10) and Waste Biosludge (SP-12) 

During the pre-sampling set-up, the ship notified EPA that galley, laundry, and food pulper wastewater would be discharged prior to docking in Whittier, Alaska (prior to the start of the sampling episode), antanks would not be discharged again until after the 5-day sampling episode had ended. Discharge priowas necessary since the ship would be greater than 12 nm from shore, and the crew needed wastewater embarking new passengers. Therefore, to characterize these four waste streams as discharged, samples August 26, 2004, approximately 1.5 days prior to the start of the sampling episode. These samples werappropriate laboratories from Whittier on August 28. Because the onboard pathogen indicators laboratoperating at the time of sample collection, pathogen indicator analyses for these samples were performhours outside the required 6-hour holding time; the resulting data are not considered valid. 

Food Pulper Overboard Discharge (SP-10) and Waste Biosludge (SP-12), Semivolatile Organics Analysis 

The analytical laboratory notified EPA that the food pulper overboard discharge samples for semivolatwere received broken. Therefore, the sampling team collected a second food pulper overboard discharsemivolatile organics analysis on September 2, 2004 after the 5-day sampling episode had ended. Upothe laboratory data package, EPA discovered that the waste biosludge sample was broken and not the fdischarge sample. As a result, the analytical database for the Island includes two sets of semivolatiles overboard discharge and no semivolatile data for waste biosludge. The second set of semivolatiles datoverboard discharge can be found in Appendix A-2.

4.0 RESULTS AND DISCUSSION 

This section presents the data collected during this sampling episode. Section 4.1 

presents the analytical results and discussion; Section 4.2 presents interview results for activities 

that impact wastewater generation; and Section 4.3 presents flow data and analysis. Analytical 

results for field measurements performed onboard are presented in Appendix A-3. Note that 

anomalous analytical results were obtained for available and total cyanide; these data have not 

been excluded from the data set, but the results are presented in and discussed in Section 5.1.1 

(in the data quality section of this report) and not in the current section. 

4.1 Laboratory Analytical Results and Discussion 

4.1.1 Graywater 

Tables 4-1 through 4-3 present analytical results for galley, laundry, and 

accommodations wastewater, respectively, which were collected for five consecutive 24-hour 

sampling periods during the sampling episode. Table 4-4 presents average analytical 

concentrations for these three graywater sources. Only those analytes detected at least once in 

any of the wastewater samples (i.e., graywater sources, influent to treatment system, or effluent 

from treatment system) are included in this table. Appendices A-1 and A-2 present results for 

both detected and nondetected analytes. 

Of the 295 analytes tested for in the graywater sources, 64 were detected in the 

graywater waste streams. Thirteen of these 64 analytes were also detected at some level in the 

equipment blank (flagged by an “e” in Tables 4-1 through 4-5; see Table 5-2 for equipment 

blank results), meaning that the sampling equipment may have contributed some or all of these 

analytes to the samples. EPA will consider the impact of possible contamination from sampling 

equipment in a future analysis. Twenty-one of these 64 detected analytes were also detected at 

some level in the potable water used as source water for all graywater systems (flagged by an “s” 

in Tables 4-1 through 4-5; see Table 4-12 for source water results), meaning that the source 

water may have contributed some or all of these analytes to the samples.

Chart 2 presents the number of analytes that were detected in each graywater 

source at the highest average concentration. For example, the highest average detected 

concentrations for all three pathogen indicators were found in the galley wastewater. Note that a 

graywater source that has the highest concentration of an analyte will not necessarily contribute 

the greatest amount of that analyte to the wastewater treatment system or overboard discharge. 

The total amount of an analyte contributed by a particular graywater source also will depend on 

that source’s volume compared to the volumes of the other sources. Flow (and thus volume) 

information was not able to be collected for all graywater sources (see Table 2-1).

Galley wastewater contained a total of 61 analytes and showed the second highest 

average concentrations for 53 analytes, including all pathogen indicators, most classical 

pollutants, and most organics. Galley wastewater showed the highest average concentration of 

several analytes commonly used to measure wastewater strength: all 3 pathogen indicators, 

biochemical oxygen demand (BOD5), chemical oxygen demand (COD), hexane extractable 

material (HEM), and total suspended solids (TSS). The galley wastewater was the only 

graywater source that was analyzed for pesticides because this was the most likely possible 

source of these analytes; none were detected. 

Laundry wastewater contained a total of 52 analytes and showed the highest 

average concentrations for 6 analytes, including nitrate/nitrite, total silver, total and dissolved 

lead, total titanium, and chloroform. The laundry wastewater was the only graywater source that 

was analyzed for dioxins and furans because this was the most likely possible source of these 

analytes; none were detected. 

Accommodations wastewater contained a total of 54 analytes and showed the 

highest average concentrations among the graywater sources for 5 analytes, including total 

aluminum, total beryllium, total and dissolved mercury, and total vanadium. 

Galley, laundry, and food pulper wastewaters are collected into holding tanks and 

held for discharge untreated outside of 12 nm from shore. Table 4-5 presents analytical results 

for galley, laundry, and food pulper overboard discharge samples, which were collected as onetime grab samples as these wastewaters were discharged overboard. In general, the same 

pollutants were detected in the wastewaters as generated and during overboard discharge for 

both the galley and laundry wastewater. (System piping precluded collection of samples of food 

pulper wastewater as generated.) Variability in pollutant concentrations is likely caused by 

variations in wastewater generation over time rather than by changes in wastewater 

characteristics during wastewater storage. 

4-3
 
4.1.2 Influent to Treatment System 

Table 4-6 presents analytical results for the influent to the treatment system, 

which was sampled for five consecutive 24-hour sampling periods. Only those analytes detected 

at least once in any of the wastewater samples (i.e., graywater sources, influent to treatment 

system, or effluent from treatment system) are included in this table. Appendices A-1 and A-2 

present results for both detected and non-detected analytes. 

Pathogen Indicators and Classical Pollutants 

All 3 pathogen indicators and all 16 classical analytes were detected in the 

influent to treatment samples. Three of these detected analytes were also detected at some level 

in the potable water used as source water for all graywater and sewage systems (flagged by an 

“s” in Table 4-6; see Table 4-12 for source water results), meaning that the source water may 

have contributed some or all of these analytes to the samples. None of these analytes were 

detected in the equipment blank. 

Wastewater conservation practices used onboard, such as use of vacuum toilets, 

result in highly concentrated wastewater. Chart 3 compares the influent to the Island treatment 

system to typical domestic wastewater for selected pathogen indicators and classical pollutants. 

Fecal coliform and enterococci concentrations in the influent to the Hamworthy treatment system 

were two or more orders of magnitude greater than in typical untreated domestic wastewater. 

Key analytes commonly used to assess wastewater strength, such as BOD5, TSS, and COD, were 

detected at concentrations two or more times greater than typical domestic wastewater.

ND - Not detected. 

Total and Dissolved Metals 

Of the 35 metal analytes detected in the influent to treatment samples, 27 were 

detected in every influent to treatment sample (Table 4-6). Ten of these 35 metal analytes were 

detected at some level in the equipment blank (flagged by an “e” in Table 4-6; see Table 5-2 for 

equipment blank results), meaning that the sampling equipment may have contributed some or 

all of these analytes to the samples. EPA will consider the impact of possible contamination 

from equipment in a future analysis. Seventeen of these detected metal analytes were also 

detected at some level in the potable water used as source water for all graywater systems 

(flagged by an “s”in Table 4-6; see Table 4-12 for source water results), meaning that the source 

water may have contributed some or all of these analytes to the samples. 

The 10 metal analytes detected at the highest concentrations were: total and 

dissolved sodium, total and dissolved magnesium, total and dissolved calcium, total aluminum, 

total copper, total iron, and total zinc. Total chromium, total and dissolved copper, total lead, 

total mercury, total and dissolved nickel, total and dissolved selenium, and total and dissolved 

zinc are priority pollutant metals (designated by EPA in 40 CFR Part 423, Appendix A) that 

were detected in every influent to treatment sample. Some metals may result from contact with 

carbon steel and stainless steel pipes and tanks in the ship. 

4-5
 
Volatile and Semivolatile Organics, Pesticides, PCBs 

Among the 365 target analytes for volatile and semivolatile organics, pesticides, 

and polychlorinated biphenyls (PCBs), 42 were detected in any Island influent to treatment 

samples: 2 semivolatile organics, 3 volatile organics, 1 pesticide, and 36 PCBs (Table 4-6). 

Neither of the 2 detected semivolatile organics were detected in the equipment blank (see Table 

5-2 for equipment blank results; volatile organics, pesticides, and PCBs were not analyzed for in 

the equipment blank). EPA will consider the impact of possible contamination from equipment 

in a future analysis. 

Two semivolatile organics were detected in the influent to treatment: bis(2­

ethylhexyl)phthalate and phenol. Bis(2-ethylhexyl)phthalate is used as a plasticizer (a chemical 

added to plastics to make them flexible) and is commonly detected in environmental samples 

(ATSDR, 2002). Cruise ships use a wide variety of plastic products (e.g., floor tiles, shower 

curtains, hoses, packaging materials and containers, PVC piping) that may result in the presence 

of bis(2-ethylhexyl)phthalate in the influent to treatment. 

Phenol is both man-made and produced naturally. It is found in human wastes 

(urine), which is the most likely source for phenol’s presence in the influent to the Island 

treatment system. It is also found in some foods (smoked summer sausage, fried chicken, 

mountain cheese, some species of fish). Man-made sources include the use of phenol as a 

slimicide, as a disinfectant, and in medicinal preparations such as ointments, ear and nose drops, 

and antiseptic wipes. (ATSDR, 1998) All of these are possible sources for the presence of 

phenol in cruise ship wastewater. Phenol was also detected in the source water (see Table 4-12 

for source water results), meaning that the source water may have contributed some or all of this 

analyte to the samples. 

Three volatile organics were detected in the influent to treatment: methylene 

chloride, toluene, and tetrachlorethene. Methylene chloride and toluene were each detected just 

above their respective detection limits in one of five influent to treatment system samples during 

the sampling episode. Methylene chloride is an industrial solvent commonly used in paint 

removers and degreasing agents; other uses include the production of photographic films, 

4-6
 
pharmaceuticals, inks, and adhesives. Methylene chloride can also serve as a propellant for 

insecticides, air fresheners, and paints. (ATSDR, 2001) Toluene is a component of fuels made 

from crude oil; it is also a solvent used in the production of paints, paint thinners, adhesives, and 

rubbers (ATSDR, 2001). Methylene chloride and toluene were not detected in any of the 

accommodations wastewater samples; therefore, the source of these analytes may be the sewage 

CHT system. 

Tetrachloroethene was detected in three of five influent to treatment system 

samples. Tetrachloroethene is a solvent used in metal cleaning and dry cleaning (ATSDR, 1997). 

The Island has a dry cleaning facility. According to the ship’s crew, all tetrachloroethene wastes 

are collected for shoreside waste disposal. Tetrachloroethene was not detected in the 

accommodations wastewater (or any other graywater samples); therefore, the source may be the 

sewage CHT system. 

Thirty-six PCB congeners and co-eluting congener groups were detected in the 

influent to the wastewater treatment system. Total PCBs in the influent were measured at a 

concentration of 37,100 pg/L. Two of the detected PCBs were identified as “toxic” by the World 

Health Organization: PCB 105 (406 pg/L) and PCB 118 (984 pg/L). PCBs have traditionally 

been associated with electrical equipment, such as transformers; however, they have also been 

used in paint formulations, carbonless copy paper and plastics (EPA, 2005). None of the 

detected PCBs have any known manufacturers. (Note that PCBs were not analyzed for in source 

water.) 

Simazine was the only pesticide detected in the influent to the treatment system. 

EPA lists simazine as a General Use Pesticide (GUP) that has been used to control broad-leaved 

weeds and annual grasses in fields, berry fruit, and vegetables. Simazine is classified by EPA to 

be slightly toxic to practically non-toxic. In the past, simazine has been used to control algae in 

swimming pools, hot tubs, and whirlpools. (Extoxnet, 1996) 

4-7
 
4.1.3 Influent to the Ultraviolet (UV) Disinfection Part of the Treatment System 

Table 4-7 presents pathogen indicator results for the influent to UV disinfection 

part of the Island’s wastewater treatment system. Grab samples for individual pathogen 

indicator analyses were collected for five consecutive 24-hour sampling periods. Pathogen 

indicators, which were generally in the millions at the influent to the treatment system (see Table 

4-6), were generally reduced to nondetect or close to the detection limit after the bioreactor and 

membrane filter (i.e., before the UV disinfection step). Data for the pathogen indicators in the 

final effluent (i.e., after the UV disinfection step) are presented in the next section. 

4.1.4 Effluent from the Treatment System 

Table 4-8 presents analytical results for the effluent from treatment system, which 

was sampled for five consecutive 24-hour sampling periods. Only those analytes detected at 

least once in any of the wastewater samples (i.e., graywater sources, influent to treatment 

system, or effluent from treatment system) are included in this table. Appendices A-1 and A-2 

present results for both detected and nondetected analytes. 

Pathogen Indicators and Classical Pollutants 

A total of 15 grab samples were collected for analysis of the three pathogen 

indicators over the five 24-hour sampling periods (results and collection times for each grab 

sample are presented in Appendix A-1). Pathogen indicators generally were not detected in the 

effluent from the treatment system; the exceptions to this were three grab samples in which E. 

coli was detected at levels close to the detection limit (one sample on Day 1 and two samples on 

Day 4), three grab samples in which enterococci was detected at levels close to the detection 

limit (Day 1, Day 4, and Day 5), and one grab sample in which fecal coliform was detected at 20 

CFU/100 mL on Day 1 (detection limit is 2 CFU/100 mL). 

Thirteen of the 16 classical pollutants were detected in effluent from treatment 

system samples; 3 classical pollutants (HEM, SGT-HEM, and settleable residue) were not 

4-8
 
detected in any effluent samples. Three of the 13 detected classical analytes were also detected 

at some level in the potable water used as source water for all graywater and sewage systems 

(flagged by an “s” in Table 4-8; see Table 4-12 for source water results), meaning that the source 

water may have contributed some or all of the analytes to the sample. None of these analytes 

were detected in the equipment blank. 

Chart 4 shows that classical pollutant concentrations in the effluent from the 

Island treatment system are lower than EPA’s standards for secondary treatment.

Total and Dissolved Metals 

Among the 54 total and dissolved metal analytes tested for, 31 were detected in 

one or more effluent from treatment samples (Table 4-8). Of these 31 detected metal analytes, 

22 were detected in every effluent from treatment sample. Eight of the 31 detected metal 

analytes were also detected at some level in the equipment blank (flagged by an “e” in Table 4-8; 

see Table 5-2 for equipment blank results), meaning that the sampling equipment may have 

contributed some or all of this analyte to the samples. EPA will consider the impact of possible 

contamination from equipment in a future analyses. Seventeen of these detected metal analytes 

were also detected at some level in the potable water used as source water for all graywater and 

sewage systems (flagged by an “s” in Table 4-8; see Table 4-12 for source water results), 

meaning that the source water may have contributed some or all of the analytes to the sample. 

The 10 metal analytes detected at the highest concentrations were total and 

dissolved calcium, magnesium, sodium, zinc, and boron. Total and dissolved copper, nickel, 

selenium, zinc, and total mercury are priority pollutant metals (designated by EPA in 40 CRF 

4-9
 
Part 423, Appendix A) that were detected in every effluent from treatment sample. Some metals 

may results from contact with carbon steel and stainless steel pipes and tanks in the ship. There 

are no EPA secondary treatment standards for metals. 

Volatile and Semivolatile Organics, Pesticides, PCBs, Dioxins and Furans 

Among the 84 target analytes for volatile and semivolatile organics analyzed, 

only two–phenol and bis(2-ethylhexyl)phthalate–were detected in any Island effluent samples 

(Table 4-8). Phenol is found in urine and bis(2-ethylhexyl)phthalate is used in plastics (see 

Section 4.1.2). Phenol was detected at some level in the potable water used as source water for 

all graywater and sewage systems (flagged by an “s” in Table 4-8; see Table 4-12 for source 

water results), meaning that the source water may have contributed some or all of the analyte to 

the sample. 

Pesticides, PCBs, and dioxins and furans were not analyzed for in the effluent 

from the treatment system. 

4.1.5	 Wastewater Treatment System Performance: Comparison of Influent to 

Treatment System and Effluent from Treatment System 

The Hamworthy treatment system successfully removed almost all pathogen 

indicators (>99%; Table 4-9) and most classical pollutants, metals, and organics (Tables 4-9 and 

4-10). 

Pathogen Indicators and Classical Pollutants 

Pathogen indicators were generally removed by the bioreactor and membrane 

filters to levels below detection (>99% removal), while any remaining indicators were generally 

removed by UV disinfection (overall system efficiency >99%, see Table 4-9). Enterococci and 

E. coli were each detected in 3 of the 15 effluent from treatment samples at levels close to the 

detection limit; fecal coliform was detected in 1 of the 15 samples. 

4-10
 
The treatment system removed almost all biochemical oxygen demand (BOD5) 

(99%), and most chemical oxygen demand (COD) (93%) and total organic carbon (TOC) (89%) 

(Table 4-10). The system also removed almost all settleable residue and total suspended solids 

(TSS) (both 99% or greater). Oils and greases (HEM and SGT-HEM) were removed to levels 

below detection. 

The treatment system reduced ammonia by 58%, while reducing total Kjeldahl 

nitrogen (TKN, which measures both ammonia and organic forms of nitrogen) and total 

phosphorus by approximately 75% (Table 4-10). Nitrate/nitrite levels are low and remained 

relatively unchanged. Nitrogen is likely taken up by the microorganisms in the bioreactor and 

removed from the system in the waste biosludge. It is unlikely that nitrogen is removed by 

nitrification (the mechanism of ammonia biodegradation) as nitrification would have resulted in 

an increase in nitrate/nitrite concentration, but these levels remained relatively unchanged. 

Phosphorus also is most likely taken up by the microorganisms in the bioreactor as evidenced by 

elevated total phosphorus concentrations in the waste biosludge (see Section 4.1.6 and Table 4­

11). 

Total and Dissolved Metals 

The total metals analysis measures both the particulate and dissolved forms of 

metals, while the dissolved metals analysis measures only the dissolved form. The difference 

between the total and dissolved metals measurements is the particulate metals concentration. 

Metals were present in both particulate and dissolved forms in the influent to the treatment 

system (i.e., the total metals concentrations exceeded the dissolved metals concentrations for 

most metal analytes) (Table 4-6). In comparison, metals were predominantly present in the 

dissolved form in the effluent from the treatment system (i.e., the total and dissolved metals 

concentrations were similar in these samples) (Table 4-8). Furthermore, there were elevated 

metals concentrations in the screening solids and waste biosludge (see Table 4-11). This means 

that the treatment system is highly efficient in removing particulate metals, as would be expected 

for membrane filtration (and as supported by $99% removal of settleable residue and TSS, see 

Table 4-8). The treatment systems removed dissolved metals with an average efficiency of 37% 

(Table 4-10). 

4-11
 
Volatile and Semivolatile Organics, Pesticides, PCBs, Dioxins and Furans 

The treatment system was able to remove most of the volatile and semivolatile 

organic compounds to levels below detection (Table 4-10). Possible removal mechanisms 

include biological degradation, adsorption onto wastewater treatment sludge (see Table 4-11), 

and/or volatilization. 

Simazine was the only pesticide detected in the influent to treatment, and 

pesticides were not analyzed for in the effluent from treatment. While PCBs were detected in the 

influent to treatment, they were not analyzed for in the effluent from treatment. EPA has no data 

regarding the performance of the Hamworthy treatment system for removing pesticides and 

PCBs. Dioxins and furans were not analyzed for in either the influent to or effluent from the 

treatment system. Dioxins and furans were analyzed for in laundry wastewater, and none were 

detected. 

4.1.6 Screening Solids, Waste Biosludge, and Incinerator Ash 

Table 4-11 presents the results for analytes detected in one-time grab samples of 

screening solids (from screens presses at the beginning of the treatment system), waste biosludge 

(excess biological mass from the treatment system’s bioreactor), and incinerator ash (from 

incineration of trash, screening solids, and spent bag filters) collected during the sampling 

episode. Table 4-11 also shows the average influent to treatment analyte concentrations from 

Table 4-10 for comparison. 

Most of the analytes detected in the screening solids and waste biosludge were 

also detected in the influent to treatment. For many analytes, concentrations in the screening 

solids and waste biosludge exceeded those in the influent to treatment, suggesting that these 

analytes are removed from the system in these waste streams. See Section 4.1.5 for a detailed 

discussion of wastewater treatment system performance. 

4-12
 
4.1.7	 Source Water 

Potable water is used as source water for all ship operations that generate 

graywater and sewage (e.g., laundry, galley, food pulper, sinks, showers, and toilets). Potable 

water is produced onboard and bunkered while in port, with produced water providing 

approximately two-thirds of freshwater requirements and bunkered water providing 

approximately one-third of freshwater requirements. Seven total metals, 11 dissolved metals, 3 

classical pollutants, and 1 organic were detected in the one-time grab sample of potable water 

collected during this sampling episode (Table 4-12). None of the analytes detected in the source 

water exceeded Federal drinking water standards (Table 4-12). Pathogen indicators were not 

detected in the source water sample. 

4.2	 Summary of Interviews Regarding Activities that Impact Wastewater 

Generation 

The ship’s crew was interviewed to obtain information regarding activities that 

impact wastewater generation (see Appendix C for detailed reports). The ship’s crew provided 

operational, discharge, and wastewater treatment operating logs corresponding to the period of 

the sampling episode. These documents are included in the Cruise Ship Rulemaking Record and 

are available upon request. 

4.2.1	 Wastewater Generation 

Galley 

The Island has two main dining rooms, four additional restaurants, and 24-hour 

room service. Approximately 10,000 meals (breakfast, lunch, dinner, and snacks) are served 

daily. The ship's ten main automatic washing machines operate 24-hours a day. Dishes are 

washed using Solid Power and Super Trump (high alkaline solid automatic dishmachine 

detergents). Floors are washed using Encomp cleaning solution. Material Safety Data Sheets 

(MSDS) for these products are included in the Cruise Ship Rulemaking Record and are available 

upon request. 

4-13
 
Laundry

 The Island operates one large continuous tunnel washer to wash towels and 

linens from approximately 0800 to 1500 and 2000 to 0100 each day. Cleaning agents (Laundri 

SL-2000 and Eco-Star Detergent 1) are dispensed automatically using a computer-controlled 

menu depending on the material and degree of soiling. The Island operates two large washing 

machines to wash blankets (total of 10 loads per day at 300 pound capacity each) and two small 

washing machines (50 pound capacity) to wash passengers’ personal items (operate from 

approximately 2000 to 0600 each day). MSDS for laundry cleaning agents are included in the 

Cruise Ship Rulemaking Record and are available upon request. Finally, the Island has six 

passenger laundrettes and six crew and officer laundrettes, processing approximately 40 pounds 

of laundry per load. 

Photo Processing 

The Island has an onboard photo processing lab with all digital photo processing 

equipment. All waste photographic chemicals are collected into drums for disposal onshore. The 

drums are stored within secondary containment to capture any spills. The sink in the photo lab 

drains to a drum for disposal onshore. The photo lab has two floor drains that are capped to 

ensure that spilled chemicals do not enter the drain system. Any spills are captured in in-room 

storage containers for shore disposal. 

Print Shop 

The Island houses a print shop. The floor drain is capped and any spills are 

captured in an in-room storage container for shore disposal. The print shop sink drains to a drum 

for onshore disposal. All print shop wastes (cleaning rags with solvents and chemical residues) 

are disposed of as hazardous waste onshore. 

4-14
 
Dry Cleaning 

The Island has a dry cleaning facility. One Renzacci dry cleaning machine 

processes approximately five loads per day using auto-distillation of solvent. This machine 

generated five liters of spent solvent during the first seven months of 2004; spent solvent is 

disposed of onshore as hazardous waste. Dry cleaning wastewater (condensate separator water) 

is routed to the laundry CHT system. Two Aquatex machines process approximately 15 loads 

per day using a water-based chemical which produces non-hazardous waste, according to the 

crew. Aquatex wastewater and lint waste is routed to the laundry CHT systems. No sinks or 

floor drains are present in the dry cleaning facility. 

Chemical Storage 

Any spills from the engine room storage areas are captured in the bilge and do not 

enter the graywater or sewage systems. See Appendix C for more information on chemicals 

stored in each engine room. Chemicals are also stored in other rooms of the ship as listed in 

Appendix C; none of the storage rooms have floor drains to ensure that spilled chemicals do not 

enter the graywater and sewage systems. 

Medical Infirmary 

The Island has a medical infirmary. Water that enters the floor drain or sinks 

drains to the graywater system; there is no floor drain in the digital imaging room. Sinks are 

used for handwashing only; the crew indicated that no chemicals are disposed of in the sinks. 

Any wastes are collected by the environmental officer for onshore disposal. 

4.2.2 Pesticide, Fungicide, and Rodenticide Use 

The Island uses Siege Gel insecticide bait (active ingredient hydamethylnon) and 

Maxforce bait stations (active ingredient fipronil) to control insect pests. Aerosol insecticides 

used onboard include Cy-kick (active ingredient cyfluthron) and 565 Plus XLO (active 

4-15
 
ingredients pyrethrins and allethrin). MSDS for insect control agents are included in the Cruise 

Ship Rulemaking Record and are available upon request. The pesticide Simazine was detected 

in one Island influent to treatment sample. Simazine is a selective herbicide used to control 

weeds and grasses in food and feed crops; it is also widely used for nonselective weed control in 

industrial areas. In the past, Simazine was used to control submerged weeds and algae in large 

aquariums and swimming pools. (Extoxnet, 1996) 

Victor glue traps are set up to catch rodents. The Island does not use fungicides 

or rodenticides onboard. 

4.3 Flow Data 

Strap-on ultrasonic flow meters were used to collect flow measurements and to 

control automatic composite sample machines on (1) the outlet from the crew galley collection 

tank, (2) the outlet from one of the accommodations wastewater collection tanks, (3) the influent 

to wastewater treatment, (4) and the effluent from wastewater treatment (see Section 2.4 and 

Figures 2-1 and 2-2). The flow meters were programmed to record the instantaneous flow rate 

(m3/min) and total flow (m3) every five minutes. Flow data analyses presented in this section are 

based on only those flow data collected during the sampling episode of August 28 through 

September 2. Appendix B presents all flow data collected while onboard the Island from August 

23 through September 3. 

The flow meters on the outlet pipes from the galley and accommodations 

collection tanks recorded large negative flows when the tank discharge pumps were not 

operating, indicating significant backflow through these systems. Accordingly, the recorded 

flows do not accurately represent galley and accommodations wastewater generation at these 

locations and are not described further in this report. 

The total daily volume of influent to and effluent from the treatment system for 

each 24-hour sampling period are presented in Figure 4-1. The influent to the treatment system 

flow was, on average, 75 percent of the flow measured from the effluent from the treatment 

system. One possible explanation is that the ultrasonic signal to the flow meter at the influent to 

4-16
 
treatment system was weakened (or scattered) by the amount of solids present in the raw 

wastewater flowing through the pipe. A comparison of the average hourly flows indicates that 

the influent and effluent discharge flow rates show similar fluctuation throughout the day. 

Therefore, the flow measurements collected from the influent to the treatment are probably valid 

for qualitative use. The total daily flow from the influent remained relatively constant over the 

five-day sampling period, regardless of whether the ship was in port (Days 1, 4, and 5) or at sea 

(Days 2 and 3). 

The Island discontinued discharge of effluent from the treatment system for part 

of Day 3 of this sampling episode (while it cruised Glacier Bay National Park) and diverted the 

wastewater to a holding tank for overboard discharge outside of 12 nm of shore, as can be seen 

by the dip in the total daily effluent discharge on Day 3. Daily effluent flow rates and flow per 

capita are presented in Table 4-13. Per capita flow rates were calculated based on 2,925 people 

(2,019 passengers and 906 crew) onboard during the sampling episode, as reported by the ship’s 

crew. On average, each person generated approximately 41 gallons of treated wastewater per 

person per day. It is important to note that the treatment system treats only accommodations 

wastewater and sewage. The flow measurements do not reflect other activities that occur 

onboard such as wastewater generated by the galley (galley and food pulper wastewater) and 

laundry. 

Figure 4-2 presents the average effluent from treatment flow for each hour 

interval over the five consecutive 24-hour sampling periods, calculated from data collected via 

the strap-on flow meter. The highest rate of overboard discharge occurs between the hours of 

2100 and 0400.

5.0 DATA QUALITY 

Quality assurance/quality control (QA/QC) procedures applicable to the Island 

sampling episode are outlined in the Quality Assurance Project Plan for Rulemaking Support for 

Large Cruise Ships in Alaska Waters (QAPP), which can be found in the Cruise Ship 

Rulemaking Record and is available upon request. This section describes the quality control 

practices used to assess the precision and accuracy of the analytical data presented in Section 

4.0. Quality control (QC) practices used for this sampling episode include the analysis of matrix 

spikes, duplicate samples, and quality control standard checks. 

5.1 Analytical Quality Control 

EPA verified that laboratory performace was acceptable by conducting quality d 

control checks of the analytical data as specified by the QAPP. Data review chemists prepared 

written data review narratives (Appendix D) describing any qualifications of the analytical data. 

The following data were not considered to be of acceptable quality for the reasons discussed in 

Appendix D and were excluded from the data set:

There was uncertainty regarding the analytical results for available and total 

cyanide. Although these data have not been excluded from the database, the results are 

presented in Table 5-1 and not in the analytical results summary tables in Section 4.1. Available 

cyanide was detected in many samples, while total cyanide was not detected in these samples. In 

theory, the total cyanide result for any given sample will be greater than the available cyanide 

results in the same sample. Because it was not possible to determine which analysis was correct, 

EPA flagged the irreconcilable results in the database to alert data users to the presence of such 

problems (see memoranda Data Review Narrative for Classical Analytes for the Alaska Cruise 

Ship Industry Episode 6505 and Issues Associated with Results for Total Cyanide Versus Available 

Cyanide in Appendix D for a complete discussion). 

EPA did not identify any known source of cyanide onboard the Island during its 

onboard interviews regarding activities that impact wastewater generation. 

5.2 Field Quality Control 

The trip blank, equipment blank, and field duplicate results are the field QA/QC 

measures discussed in this subsection. Section 3.8 of the Island SAP discusses field QC 

specifications. Tables presented in this section include results for only those analytes detected in 

the respective field QC samples during the sampling episode. Appendices A-1 and A-2 contain 

the results for all analytes, both detected and nondetected. 

5.2.1 Trip Blank 

A trip blank was collected and analyzed for volatile organics to evaluate possible 

contamination during shipment and handling of samples. This sample consisted of high 

performance liquid chromatography (HPLC) water. The trip blank was prepared prior to the 

5-2
 
start of the sampling episode, and accompanied samples shipped to the laboratory on September 

2, 2004. 

No volatile organics were detected in the trip blank, indicating that there was no 

contamination of samples during transport, field handling, storage, or shipping. (Note that there 

is no table with the results of the analyses in this section of the report because all results are 

nondetects.) 

5.2.2 Equipment Blank 

The sampling team collected an equipment blank to assess the potential 

introduction of contaminants by sample collection equipment. The sample collection equipment 

used to collect the equipment blank was the same as that used at the sampling points: 

approximately 4 feet of Teflon® tubing connected on one end to a series of metal plumbing 

fixtures installed on each sample port, and the other end to a small segment of silicone tubing 

used in the peristaltic pump mechanism of the automatic sampler. The equipment blank was 

collected by pumping HPLC water through this equipment directly into sample bottles. 

Table 5-2 presents the detected results for the equipment blank. Six total metals 

and seven dissolved metals were detected in the equipment blank. In tables presenting the 

analytical results in Section 4.1, all 13 of these metals and hardness are flagged with an “(e)” to 

indicate they were detected in the equipment blank. EPA will consider the impact of possible 

contamination from equipment in a future analysis. 

5.2.3 Field Duplicates 

Field duplicate samples were collected to assess the precision of the entire sample 

collection, handling, preparation, and analysis process. The relative percent difference (RPD) 

between the two duplicate sample results is calculated and compared to the data quality 

objective. For this program, the QAPP provides an RPD target of field duplicate samples as less 

than 30% for all analytes of a specific analytical method. 

5-3
 
Classical Pollutants, Total and Dissolved Metals, and Semivolatile Organics 

For classical pollutants, total and dissolved metals, and semivolatile organics, 

field duplicate samples were samples collected from the same source, at the same time, then 

stored and analyzed independently. The duplicate samples were collected as split samples 

poured from the same mixed sample composite jars to minimize sample wastestream variability. 

Duplicate samples for these analytes were collected from the effluent from the wastewater 

treatment system (SP-6/7). Note that duplicate samples for dioxin and furans and pesticide 

analytes were collected during a previous sampling episode, and duplicate samples for 

HEM/SGT-HEM were not planned for this sampling program. 

Table 5-3 presents analytical results and the RPDs for these duplicate samples and 

includes analytical results for only those analytes that were detected at least once in wastewater 

samples during the sampling episode. 

There was excellent precision in sampling and analysis for this sampling episode. 

Of the 207 duplicate pairs listed in Table 5-3, 178 either achieved the RPD target, or the RPD 

could not be calculated because both of the duplicate samples were less than the detection limit. 

The RDP could not be calculated for 18 of the duplicate pairs because the analyte was detected 

in one sample but not the other. Analytical variability increases as analyte concentrations 

approach their detection limits. The 11 duplicate pairs with an RDP outside of the target (i.e., 

$30% difference) include one of the three duplicate pairs for each of total aluminum, total iron, 

total nickel, total selenium, and phenol, one of four duplicate pairs for dissolved sodium, two of 

three duplicate pairs for total mercury, and three of four duplicate pairs for dissolved selenium. 

These results are not uncommon in complex wastewater samples. 

In tables presenting the analytical results in Section 4.1, duplicate sample results 

are presented as averages (calculation uses detection limits for nondetected results). 

5-4
 
Pathogen Indicators and Volatile Organics 

For pathogen indicators and volatile organics, field duplicate samples were 

collected sequentially and not as split samples as was done for the other analytes. For these 

samples, this methodology introduced sample wastestream variability into the assessment of the 

precision of sample collection and analysis. Duplicate samples for these analytes were collected 

from the effluent from the treatment system (SP-6/7). Table 5-4 presents analytical results and 

the RPDs for these duplicate samples. Of the 42 duplicate pairs, 41 either achieved the RPD 

target, or the RPD could not be calculated because both of the duplicate samples were less than 

the detection limit. The RDP could not be calculated for one of the duplicate pairs because the 

analyte, E. coli, was detected in one sample but not the other. Analytical variability increases as 

analyte concentrations approach their detection limits. 

In tables presenting the analytical results in Section 4.1, duplicate sample results 

are presented as averages (calculation uses detection limits for nondetected results). In the case 

of pathogen indicators, average daily results presented incorporate both duplicate grab samples 

and multiple grab samples collected for individual analysis during each 24-hour sampling period. 

First, duplicate results, where applicable, were averaged to determine the average individual grab 

sample results for that sample (e.g., grab 1 duplicate sample results for Day 3 were averaged 

together to represent the average grab 1 sample result for Day 3). Next, the individual grab 

sample results for each day were averaged to calculate the average daily pathogen indicators 

results presented in the tables (e.g., grab sample results 1 through 3 for Day 3 were averaged 

together to calculate the average Day 3 pathogen indicators sample results). In this way, the 

average daily pathogen indicators results presented in the tables are weighted equally by time of 

day, rather than weighted more heavily by the particular time of day when duplicate grab 

samples were collected.
