# Sampling Episode Report for Island Princess

This Sam p ling Episode Report describes the sam p ling and analysis activities to

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

Island Princess while in Alaska waters. This sam p ling took place from August 28 through

Septem ber 2, 2004, under the direction of the U.S. Environm ental Protection Agency (EPA).

The sam p ling program is part of EPA' s data coll ection effort to evaluate whether to develop

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

500 or m o re 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 Kachem ak Bay

National Estuarine Research Reserve. EPA will use inf o rm ation f r om the sam p ling of this vessel

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

large cruise vessels with advanced wastewater treatm e nt system s.

EPA selected the Island Princess to characterize the perform a nce of the

Ham w orthy KSE Ltd. m e m b rane bioreactor treatm e nt system , a wastewater treatm e nt system

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

Sam p les were collected of various graywater sources (galley, laundry, accom m odations, and

food pulper wastewater); influent to the treat m e nt system (m ixed accom m odations wastewater

and sewage); influent to UV disinfection com ponent of the treatm e nt system ; effluent from the

treatm e nt system ; source water; wastewater treat m e nt residuals (screening solids and wastewater

biosludge); and incinerator ash. Most wastewater sam p les were collected for five consecutive

24-hour sam p ling periods; food pulper wastewater, treatm e nt residuals, and incinerator ash were

collected for a single 24-hour sam p ling period.

Strap-on ultrasonic flow m e ters were installed near the sam p ling locations for the

galley wastewater, accom m odations wastewater, influent to treatm e nt, and effluent from

treatm e nt to collect flow data and to trigger autom a tic sam p ling m a chines.

vi

# Various sam p le collection m e thods (com posite by flow, com posite by tim e, grab,

and grab com posite) were used depending on the sam p ling point and analyte. Tested analytes

included pathogen indicators (fecal coliform

, E.coli , and enterococci), classical pollutants, total

and dissolved m e tals, volatile and sem i volatile organics, pesticides, polychlorinated biphenyls,

and dioxins and furans. Not all sam p les were analyzed for all target analytes.

The galley wastewater sam p les showed the largest num ber of analytes detected

am ong graywater sources and the highest concentrations of several analytes com m only used to

m easure wastewater strength: all three pa thogen indicators, biochem i cal oxygen dem a nd

(BOD

5 

# ), chem ical oxygen dem a nd (COD), hexane extractable m a terial (HEM), silica-gel hexane

extractable m a terial (SGT-HEM), and total suspended solids (TSS). Laundry wastewater

sam p les had the highest concentration am ong graywater sources for six analytes, while

accom m odations wastewater had the highest concentration for five analytes.

Because of water conservation m easures onboard cruise ships (such as vacuum

toilets), key analytes such as pathogen indicators, BOD

5 

# , COD, and TSS are found at m u ch

higher concentrations in the influent to the Island Princess wastewater treatm ent system than in

typical dom estic wastewater. Of the 54 m etal analytes test ed for, 27 were detected in every

influent to treatm ent system sam p le. Am ong the 203 target analytes for volatile and sem i volatile

organics and pesticides, only 6 were detected in any Island Princess influent to treatm ent sam p les,

m o st at concentrations close to their detection lim its. Am ong the 160 polychlorinated biphenyl

(PCBs) analytes tested for, 36 were detected in Island Princess influent to treatm ent sam p les.

The Island Princess' Ham w orthy wastewater treatm ent system treats only

accom m odations wastewater and sewage. The system successfully rem oved alm o st all pathogen

indicators (>99%) and m o st classical pollutants, m e tals, and organics. Fecal coliform

, a

pathogen indicator, was detected in only 1 of the 15 effluent from treatm e nt sam p les, while

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

their detection lim its. The treatm e nt system rem oved alm o st all BOD

5 

# (99%), COD (93%), TOC

(89%), settleable residue ( >99%) and TSS (99%). The treatm e nt system reduced am m onia by

58%, total Kjeldahl nitrogen (TKN, which m easures both am m onia and organic form s of

vii

# nitrogen) and total phosphorus by approxim a tely 75%, while nitrate/nitrite levels rem a ined

relatively unchanged. The treatm e nt system was hi ghly efficient at rem oving particulate m e tals,

and rem oved dissolved m e tals at an average of 37%. The treatm e nt system rem oved m o st of the

volatile and sem i volatile organics to concentrations below detection levels.

The Ham w orthy wastewater treatm e nt sy stem generates two types of residual

waste: screening solids (from the two screen presses at the beginning of the treatm e nt system )

and waste biosludge (excess biological m a ss from th e treatm e nt system ’s bioreactor). Screening

solids are collected and incinerated onboard. W a ste biosludge is pum ped to a double-bottom

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

analytes detected in the waste biosludge were also detected in the influent to the treatm ent

system

. For m a ny analytes, concentrations in the screening solids and waste biosludge exceeded

those in the influent to treatm e nt, suggesting that these analytes are rem oved from the system in

these waste stream s.

On average, each person generated approxim a tely 41 gallons of treated

accom m odations and sewage wastewater per person per day.

# This Sam p ling Episode Report describes the Environm ental Protection Agency’s

sam p ling and analysis activities to characterize graywater and sewage generation and treatm ent

by Princess Cruises’ cruise ship Island Princess (Island) while in Alaska waters. This sam p ling

took place from August 28 through Septem ber 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 W e tlands, Oceans, and W a tersheds of the U.S.

Environm ental 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 m a xim u m cruising speed is

24 knots. Its port of registry is Berm uda. During the sam p ling episode, the Island carried 2,019

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

# This sam p ling program is a part of EPA’s data collection effort to evaluate

whether to develop wastewater discharge regulati ons for cruise vessels authorized to carry 500

or m o re passengers for hire when operating in the waters of the Alexander Archipelago or the

navigable waters of the United States within th e State of Alaska or within the Kachem ak Bay

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

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

Appropriations Bill (H.R. 5666) passed by Congr ess on Decem ber 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 inform ation gathered through this sam p ling episode were collected using EPA' s

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

Cruise Lines voluntarily provided inform ation and data gathered for and represented in this

report, notwithstanding the above cited authority, in the interest of research for the im provem ent

of wastewater treatm ent standards.

EPA selected the Island to characterize the perform ance of the Ham w orthy KSE

Ltd. (Dorset, England) m e m b rane wastewat er bioreactor treatm ent system (Ham worthy

treatm ent system ), an advanced wastewater treatm ent system that uses aerobic biological

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

analytical and flow data included in this sam p ling episode report to evaluate the perform ance of

the Ham w orthy treatm ent system , and to analyze patterns and variability in wastewater sources.

Sam p les 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/ocean s/cruise_ships/ GenericSAP040602.pdf

. P athogen indicator

analyses were performe d onboard. Sam p les for all other analyses were shipped to shoreside

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

in this sam p ling episode.

# This section describes graywater and sewage generation, collection, and treatm e nt

on the Island, as well as the sam p le collection points and flow m e ter locations and installation

points used in this sam p ling episode.

2.1 Wastew a ter Generation and Collection

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

graywater and sewage generated onboard to the ship’s Ham w orthy treatm e nt 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 com posed of five subsystem s , referred

to by the ship’s crew as the galley, food pulper, accom m odations, laundry, and sewage system s.

Figure 2-1 is a sim p lified diagram of the Island’s graywater and sewage CHT system

.

W a stewater sources collected by each of the five subsystem s are described in Table 2-1. The

Ham w orthy treatm e nt system treats only accom m oda tions wastewater and sewage. The other

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

outside of 12 nautical m iles (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

approxim a tely two-thirds of freshwater requirem e nts and bunkered water providing

approxim a tely one-third of fresh water requirem e nts.

2.2 Wastew a ter Treatment

The Island is outf itted with a Ham w orthy treatm e nt system , an advanced

treatm e nt system that uses aerobic biological treatm e nt f o llowed by ultraf iltration and ultraviolet

(UV) disinfection. Figure 2-2 provides a si m p lified diagram of the Ham w orthy treatm e nt

system

. This system treats only accom m odations wastewater and sewage onboard the Island.

2-1

# W a stewater from the accom m odations CHT system culm inates in two holding

tanks, which are pum ped to two wastewater buffer tanks, the first com ponent of the Ham w orthy

treatm e nt system

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

culm inates in four sewage collection tanks. Accom m odations wastewater from the buffer tanks

and sewage f r om the storage collection tanks m i xes in a com m on line and then splits f o r

treatm e nt through two parallel treatm e nt trains. The first unit of the treatm e nt trains are selfcleaning screen presses (m esh size 400 μm ) to rem ove paper and other coarse solids. Next, the

wastewater is pum ped to the first stage aerated bioreactors, then to interstage bag filters (m esh

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

(wastewater containing organic m a tter and biol ogical floc) overflows from the second stage

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

diffusers at the bottom s of the bioreactors.

From the second stage bioreactors, the wastewater is pum ped through the

m e m b rane filters (ultrafiltration, pore size 40 nm ) and collects into perm eate tanks. The

m e m b rane f ilters use cross f l ow design (wastewater f l ows parallel to m e m b rane surf ace) to

m i nim i ze fouling. Mem b rane concentrate, consisting of particulate m a tter and m i xed liquor, is

returned to the second stage bioreactors. Approxim a tely once every two weeks, the treatm e nt

trains are taken offline for approxim a tely 1.5 hours to disinfect the m e m b rane filters using

sodium hypochlorite; the sodium hypochlorite solution rem a ins in the system

. (W hen one

treatm e nt train is being disinfected, all wastewat er is diverted to the second, parallel treatm e nt

train.) In the final stage of treatm e nt, the com b ined wastewater from the two perm eate tanks

undergoes UV disinfection. The hydraulic residence tim e of the treatm e nt system (i.e., the

am ount of tim e the wastewater stays in the treatm e nt system ) is less than one day.

According to the ship’s crew, the Ham w orthy system can treat 600 m 3 

# (159,000

gallons) per day of sewage and accom m odations wastewater generated onboard, well in excess

of its typical daily load, approxim a tely 450 m 3 

# (119,000 gallons) as determ ined by interviews

with the ship’s crew and m easured flows collected during the sam p ling episode.

2-2

# The Ham w orthy treatm e nt 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 wast ewater from this system overboard. W h ere

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 m iles (nm ) from shore.

Treated wastewater is recycled back to the treatm e nt system when effluent total

suspended solids concentrations exceed 27 m g /L (determ i ned based on a correlation to m e asured

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

The Ham w orthy system generates three types of residual waste: screening solids

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

(excess biological m a ss from the second stage bioreactors). The screening solids (50

kilogram s/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 m a nually fed to the onboard incinerator via a sm all

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

Approxim a tely 10 m e tric tons of waste biosludge are rem oved from the second

stage bioreactors each week to m a intain bioreactor total suspended solids (m ixed liquor

suspended solids (MLSS)) concentrations at approxim a tely 20,000 m g /L. The biosludge is not

dewatered and is im m e diately discharged overboa rd (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 Ham w orthy treatm e nt system includes a total of 48 m e m b rane m odules,

arranged in four groups of four sets of three. At any given tim e, only two of the three m e m b rane

m odules in each set are operated; the third m e m b rane m odule in each set is a backup m odule.

One m e m b rane m odule is cleaned each day, so the m e m b rane cleaning cycle repeats every 48

days. The cleaning process uses “Mem brane Cleaner Part 1" and “Mem brane 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

.

W a stewater flow through the treatm e nt system is controlled by the

accom m odations wastewater and sewage pum ps. However, during periods of reduced treatm e nt

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

822 m 3



# . The contents of these holding tanks can either be pum ped to the wastewater treatm e nt

system or held for discharge without treatm e nt outside 12 nm from shore.

Wastew a ter and Residual Sample Collection Points

Sam p les were taken from the graywater sources (galley, laundry, and

accom m odations); influent to the treatm e nt syst em (com bined accom m odations wastewater and

sewage); influent to the UV disinfection portion of the treatm e nt system ; effluent from the

treatm e nt system ; source water (water from the ship’s potable water system ); wastewater

treatm e nt residuals; and incinerator ash. Table 2-1 describes the wastewaters sam p led, their

sam p ling point locations, their flow m e ter locations (if applicable), and the num ber of days they

were sam p led. Table 2-2 provides the sam e inform ation for the treatm e nt residuals and

incinerator ash sam p led. In general, food pulper and wastewater treatm e nt residual sam p les

were taken for one 24-hour period, while sam p les of accom m odations, galley, and laundry

wastewater and the influent to and effluent fr om the treatm e nt system were taken for five 24­

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

sam p les were also collected of galley, laundry, and food pulper wastewaters as they were

discharged untreated from a double-bottom holding tank.

Sam p les were collected f r om the ship’s potable water system (source water) to

determ ine if any of the target analytes were present as background contam ination. One trip

blank was prepared and analyzed f o r volatile organics to evaluate possible contam ination during

shipm e nt and handling of sam p les. Finally, an equipm ent blank was prepared and analyzed to

evaluate possible contam ination caused by the sam p ling equipm ent.

2-4

# 2.4 Sam p les were not taken directly from the sewage CHT system

. In addition,

sam p les could not be collected of wastewater held in double-bottom holding tanks for discharge

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

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

considerations, and (2) sam p ling from the holding tank discharge m a nifold would characterize

com b ined holding tank discharges and not discharges specific to the holding tanks of interest.

Flow Meter Locations

Strap-on flow m e ters (Controlotron Model 1010) were installed at four sam p ling

locations to collect flow data and to control autom a tic com posite sam p le m achines (by triggering

sam p le collection after a defined am ount of flow passed through the pipe). The first flow m e ter

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

wastewater, SP-1; see Table 2-1 for a descripti on of wastewaters and Figure 2-1 for a sim p lified

graywater and sewage CHT system diagram show ing sam p ling points and flow m e ter locations).

The second location was on the outlet pipe from one of the eleven accom m odations collection

tanks (accom m odations wastewater, SP-3; see Tabl e 2-1 and Figure 2-1). The third location was

at the influent to the wastewater treatm e nt system on the com b ined 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 treatm e nt system (on the overboard discharge line for the treated effluent, SP-6/7; see Table

2-1 and Figure 2-2).

The sam p ling point for laundry wastewater was located on piping that would not

support installation of a strap-on flow m e ter (s ee Table 2-1), precluding collection of flow data

and flow-weighted com posite sam p les at this sam p ling point. Tim e -weighted com posite sam p les

were collected at the laundry wastewater sam p li ng point (see Table 3-1 for a description of the

sam p le collection m e thod). Flow estim ates for the food pulper wastewater were provided by the

ship’s crew.

# This section describes the sam p le collection and analysis m e thods and deviations

from the ship-specific Sam p ling and Analysis Plan for Island Princess (Island SAP; Appendix

E). A m o re detailed explanation of the sa m p ling m e thodologies, analytes and analytical

m e thods, sam p ling frequency and duration, schedule, and logistics that were followed during the

sam p ling 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 inform ation colleted during that ship visit and from subsequent

follow-up com m unication with Princess personnel. One week prior to the sam p ling episode,

personnel conducted sam p ling setup activities onboard the Island, including loading sam p ling

equipm ent and the onboard laboratory, inspecting the installed sam p ling ports, installing the

strap-on ultrasonic flow m eters, and installing and program m i ng the autom atic sam p ling

m achines.

3.2 Sample Collection and Analysis Methodology

In general, sam p les of laundry, galley, and accom m odations wastewater and

influent to and effluent from the treatm e nt system were taken for five consecutive 24-hour

periods, while wastewater treatm e nt residual sam p les were taken for one 24-hour period (see

Tables 2-1 and 2-2). System piping precluded collection of sam p les 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-tim e grab sam p les of

these wastewaters were collected, prim arily to determ ine their pathogen indicators counts.

Because the onboard pathogen indicators laboratory was not yet operating at the tim e of sam p le

3-1

# collection, pathogen indicator analyses for these sam p les were perform e d approxim a tely 18

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

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

Various sam p le collection m e thods (described in Table 3-1) were used depending

on the waste stream and analyte (see Table 3-2). Most sam p les were com posited over each 24­

hour sam p ling period or were single grab sam p les in a 24-hour period. However, m u ltiple (1 to

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

sam p les m u st be analyzed within 6 hours of collection (see Table 3-2). Table 3-3 describes the

analyte groups and lists the analytical m e thods used.

Each tim e a grab or grab com posite sam p le was taken, another separate sam p le

was placed in a separate container to perform field m easurem ents of pH, tem p erature,

conductivity, salinity, turbidity, sulfide, and free and total chlorine onboard. Tem p erature and

pH were m easured im m e diately at the sam p ling point, and the rem a ining param e ters were

m easured at the sam p le staging area onboard. See Table 3-4 for equipm ent used for these

m easurem ents. Field m easurem ents are used prim arily to determ ine sam p le preservation

requirem e nts. Sam p les (other than those used for field m easurem ents) 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 equipm ent used to m easure residual

chlorine onboard was not suitable for m easuring low levels of chlorine (detection lim it of 20

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

oxidized form s of m a nganese. Accordingly, the field m easurem ents collected during this

sam p ling episode should not be used to assess com p liance with cruise ship discharge standards.

Flow data were collected from the strap-on flow m e ters installed by the sam p ling

team

. See Section 2.4 for descriptions of the fl ow m e ter locations and Figures 2-1 and 2-2 for

their locations. The flow m e ters were program m e d to record the instantaneous flow rate

(m 3 

# /m in) and total f l ow (m 3 

# ) every five m i nutes.

3-2

# 3.3 Converting Solids Mass Units to Volume Units

The screening solids sam p les had high solids contents; theref ore, the results f o r

classical pollutants, m e tals, and volatile and sem i volatile organics were reported by the

laboratories in m a ss units. To allow for direct com p arison of these results to those of other

wastewater sam p les, m a ss units for this sam p le were converted to volum e units using the

following equation and assum i ng a sam p le density of 1:

Am ount (m ass units) * (% solids/100) = Am ount (volum e units)

All data in this report pertaining to the screening solids sam p le are reported in

volum e units. The laboratory data packages, which are included in the Cruise Ship Rulem a king

Record and available upon request, contain the original m a ss units results reported by the

laboratories. Note that the analytical results f o r the incinerator ash sam p le were also reported in

m a ss units. However, the incinerator ash results were not converted because the sam p le was

>90% solids.

3.4 Quality Assurance/Quality Control

Duplicate sam p les were collected f o r quality assurance and quality control.

Results for duplicate sam p les were averaged. See Section 5.2.3 and Tables 5-3 and 5-4 for

details on duplicate sam p ling. Other field quality control sam p les prepared for this sam p ling

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

5.2.2, respectively.

3.5 Interview w i th the Ship’s Crew

The ship’s crew was interviewed to obtain inf o rm ation regarding activities that

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

for a sum m a ry.

# 3.6 Deviations from the Sampling and Analysis Plan

The sam p ling episode proceeded as specified in the Island SAP with the

deviations described in Table 3-5.

3-4Table 3-1Sample Collection Method Descriptions, Island Princess



# 3-5Sample Collection MethodDescriptionComposite by FlowFlow-weighted composite samples were collectedusing an automatic sampling machine interfaced with an installed strap-onultrasonic flow meter (see Section 2.4).The flow meter signaled the automatic sampling machine to collect a 250-mLsamplealiquot each time a fixed quantity of wastewater passed through the wastewater pipe.The number of composite sample aliquotscollected per 24-hour sampling period ranged fromapproximately30 to 60, depending on the total volume of sample requiredfor the planned analyses each sampling day.Sample aliquots werecollected into a 10-L sample composite jar stored within thesampling machine.At the end of each 24-hour period, the sample composite jar(s) were mixed and poured into individualsample bottles for analysis.Samples collected using the composite-by-flow method best represent a waste streamflowingthrough a pipe.Composite by TimeTime-weighted composite samples were collectedusing an automatic sampling machine programmed to collect 250-mL samplealiquots at fixed time intervals.The programmed time interval differed by sampling point (see Table 3-2).The number ofcomposite sample aliquots collected per 24-hour sampling period ranged fromapproximately 30 to 40, depending on the totalvolume of sample required for planned analyses.Sample aliquots were collected into a 10-L composite jar stored within thesampling machine.At the end of the 24-hour sampling period, the sample composite jar(s) were mixed and poured intoindividual sample bottles for analysis.The composite-by-time method was used when composite-by-flow method was notfeasible.GrabGrab samples were discrete samples collected directly intothe sample bottles fromthe sample tap or through Teflon® tubingconnected to the sample tap.Note that samples for pathogenindicator analyses were collectedas grab samples (as opposed tocomposite sample ) because they must be analyzed within a 6-hour holding time.Grab compositeSamples (1 to 4 per 24-hour sampling period) were manually collected as grab samples but composited either in thefield or atthe laboratory for a single analysis.The grab composite method was used when composite-by-flow or composite-by-timemethods were not appropriate.Volatile organics– grab samples were collected directly into sample vials, which were filled completely to avoid loss of targetanalytes by volatilization.Grab samples for each 24-hour period for analysis of volatile organics were composited by thelaboratory for a single analysis.Total and available cyanide– grab samples were chemically preserved assoon as possible to minimize sample interferences.The preserved total and available cyanide grab samples for each 24-hour period were composited onboard by the sampling teamfor a single analysis.Hexane-extractable material/silica-gel treatedhexane-extractable material (HEM/SGT-HEM)– grab samples werecollected directly into sample containers to avoid loss of HEM/SGT-HEM that might adhere to the interior of any interimsampling container (e.g., sample composite jar). The sampling teamprepared composite HEM/SGT-HEM samples onboard fora single analysis per sampling point per day by filling approximately one-fourth (250-mL) of the sample containers when theycollected each grab sample, resulting in 1-liter of samplein each container at the end of each sampling period.Table 3-2Sample Collection Method and Analyte Groups Tested by Sampling Point, Island Princess

# 3-13Table 3-5Deviations from the Sampling and Analysis Plan, Island Princess



# 3-14DeviationDescriptionPathogen IndicatorsLaboratory DuplicatesFor 5% of the pathogen indicators samples, duplicate 100-mLsamplevolumes were taken with the intention that the laboratorywould composite the 100-mLsample volumes and then analyze duplicate samples fromeach composite sample to evaluatelaboratory precision (i.e., laboratory duplicates). However, the laboratory did not prepare composites, but instead analyzed eachof the 100-mLsample volumes individually. Accordingly, the results obtained fromthese analyses are field duplicate samples,not laboratory duplicates, and are presented and handled as such in this report. SeeSection 5.2.3 and Table 5-4 for details onduplicate sampling for pathogen indicators.Laundry Wastewater(SP-2), Composite SamplesThe strap-on flow meter set-up and calibration was unsuccessful atthe laundry wastewater sampling point (the inlet pipe to thelaundry wastewater holding tank), most likely due to poor pipe flowconditions such as pipe scaling or extreme aeration.As aresult, flow data could not be collected at this sampling point.In addition, the flow meter could not be used to initiatecollection of flow-weighted composite samples at SP-2 as described in the Island SAP.As an alternative samplingmethodology, the automatic sampling machine was programmed tocollect a time-weighted composite sample as described inTable 3-2.EPAconclude that the collected samples were respresentive of laundry wastewater as generated onboardthe Island.Laundry Wastewater(SP-2), Grab SamplesThe sampling teamsuccessfully collected only one set of four planned grab and grab composite samples on Day 1 of samplingdue to the inability to coordinate sample collection times with adequate wastewater volumes in the laundry holding tank.Sample volume fromthe single grab was sufficient for analysis ofpathogen indicators, volatile organics, and total cyanide, butwas not sufficient for analysis of HEM/SGT-HEM and available cyanide.Effluent fromTreatment(SP-6/7), Composite andGrab SamplesComposite by flow sampling at SP-6/7 was suspended on Day3 from0720 to 2115 because overboard discharge was restrictedwhile the ship cruise Glacier Bay.(The flow meter thatcontrolled composite by flow sample collection was located on theoverboard discharge pipe, but during this time the effluent was diverted to storage in double-bottomholding tanks.)The fourgrab and grab composite sample collection times were adjustedto account for the suspended discharge as the sample tap wasalso located downstreamof valve that diverts the treated effluent to the double-bottomholding tanks.See Appendices A-1 andA-3 for the grab and grab composite collection times, respectively.Volatile OrganicsPreservationFree chlorine was detected in pre-sampling field tests at all sampling points.Based on these results, the sampling teamprepreserved all volatile organics sample vials with sodiumthiosulfate rather than waiting to determine preservationrequirements based on the free chlorine field test results.Free chlorine was generally detected in grab samples collectedthroughout the sampling episode.(Sample vials were also prepreserved with hydrochloric acid to control biological activity asdiscussed in the Island SAP.)Table 3-5 (Continued)



# 3-15DeviationDescriptionGalley, Laundry, and FoodPulper OverboardDischarge (SP-8, SP-9, SP10) and Waste Biosludge(SP-12)During the pre-sampling set-up, the ship notified EPAthat galley, laundry, and food pulper wastewater and waste biosludgewould be discharged prior to docking in Whittier, Alaska (priorto the start of the sampling episode), and that these holdingtanks would not be discharged again until after the 5-day sampling episode had ended.Discharge prior to entering Whittierwas necessary since the ship would be greater than 12 nmfromshore, and the crew needed wastewater storage capacity prior toembarking new passengers.Therefore, tocharacterize these four waste streams as discharged, samples were collected onAugust 26, 2004, approximately 1.5 days prior to the start ofthe sampling episode. These samples were then shipped to theappropriate laboratories fromWhittier on August 28.Becausethe onboard pathogen indicators laboratory was not yetoperating at the time of sample collection, pathogen indicatoranalyses for these samples were performed approximately 18hours outside the required 6-hour holding time; the resulting data are not considered valid.Food Pulper OverboardDischarge (SP-10) andWaste Biosludge (SP-12),Semivolatile OrganicsAnalysisThe analytical laboratory notified EPA that the food pulper overboard discharge samples for semivolatile organics analysiswere received broken.Therefore, the sampling teamcollected a second food pulper overboard discharge sample forsemivolatile organics analysis on September 2, 2004 after the 5-day sampling episode had ended.Upon receipt and review ofthe laboratory data package, EPA discovered that the wastebiosludge sample was broken and not the food pulper overboarddischarge sample.As a result, the analytical database forthe Island includes two sets of semivolatiles data for food pulperoverboard discharge and no semivolatile data for waste biosludge.The second set of semivolatiles data for food pulperoverboard discharge can be found in Appendix A-2.Analytical MethodsEPA-contracted laboratories substituted comparable EPA analytical methods for certain analytes.Table 3-3 lists the actualanalytical methods used by the laboratories.Note that while the Island SAP correctly listed EPA Methods624 and 625 as the planned methods for analyzing for volatileand semivolatile organics, respectively, Appendix E of the Island SAP mistakenly listed the target analytes for EPA Methods1624 and 1625.Appendix A-2 of this report presents the actual list of target volatile and semivolatile organics.Sampling ScheduleThe sampling teamadjusted the sampling schedule in Appendix C of the Island SAP to accommodate sampling logistics andship operations.Refer to Appendix A-3 of this report foractual samples collected and sample collection dates/times.

4.1 Laboratory Analytical Results and Discussion

4.1.1 Grayw ater

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

accom m odations wastewater, respectively, which were collected for five consecutive 24-hour

sam p ling periods during the sam p ling 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 sam p les (i.e., graywater s ources, influent to treatm e nt system , or effluent

from treatm e nt 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 stream s. Thirteen of these 64 analytes were also detected at som e level in the

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

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

average concentrations for 53 analytes, incl uding all pathogen indicators, m o st classical

pollutants, and m o st organics. Galley wastewat er showed the highest average concentration of

several analytes com m only used to m easure wastewater strength: all 3 pathogen indicators,

biochem i cal oxygen dem a nd (BOD

5 

# ), chem ical oxygen dem a nd (COD), hexane extractable

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

graywater source that was analyzed for pesticides because this was the m o st likely possible

source of these analytes; none were detected.

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

average concentrations f o r 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 m o st likely possible source of these

analytes; none were detected.

Accom m odations wastewater contained a total of 54 analytes and showed the

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

alum inum , total beryllium

, total and dissolved m e rcury, 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 sam p les, which were collected as onetim e grab sam p les as these wastewaters were discharged overboard. In general, the sam e

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

both the galley and laundry wastewater. (System piping precluded collection of sam p les of food

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

variations in wastewater generation over tim e rather than by changes in wastewater

characteristics during wastewater storage.

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 treatm e nt sam p les. Three of these det ected analytes were also detected at som e level

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

have contributed som e or all of these analytes to the sam p les. None of these analytes were

detected in the equipm ent blank.

W a stewater conservation practices used onboard, such as use of vacuum toilets,

result in highly concentrated wastewater. Chart 3 com p ares the influent to the Island treatm e nt

and polychlorinated biphenyls (PCBs), 42 were de tected in any Island influent to treatm e nt

sam p les: 2 sem i volatile organics, 3 volatile organics, 1 pesticide, and 36 PCBs (Table 4-6).

Neither of the 2 detected sem i volatile organics were detected in the equipm ent blank (see Table

5-2 f o r equipm ent blank results; volatile organics, pesticides, and PCBs were not analyzed f o r in

the equipm ent blank). EPA will consider the im pact of possible contam ination f r om equipm ent

in a future analysis.

Two sem i volatile organics were detected in the inf l uent to treatm e nt: bis(2­

ethylhexyl)phthalate and phenol. Bi s(2-ethylhexyl)phthalate is used as a plasticizer (a chem ical

added to plastics to m a ke them flexible) and is com m only detected in environm ental sam p les

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

curtains, hoses, packaging m a terials and containers, PVC piping) that m a y result in the presence

of bis(2-ethylhexyl)phthalate in the influent to treatm e nt.

Phenol is both m a n-m a de and produced naturally. It is found in hum an wastes

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

treatm e nt system

. It is also found in som e foods (sm oked sum m e r sausage, fried chicken,

m ountain cheese, som e species of fish). Man-m a de sources include the use of phenol as a

slim icide, as a disinfectant, and in m e dicinal preparations such as ointm e nts, 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), m eaning that the source water m a y have contributed som e or all of this

analyte to the sam p les.

Three volatile organics were detected in the inf l uent to treatm e nt: m e thylene

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

above their respective detection lim its in one of five influent to treatm e nt system sam p les during

the sam p ling episode. Methylene chloride is an industrial solvent com m only used in paint

rem overs and degreasing agents; other uses include the production of photographic film s,

4-6

# pharm aceuticals, inks, and adhesives. Methylene chloride can also serve as a propellant for

insecticides, air fresheners, and paints. (ATSDR, 2001) Toluene is a com ponent of fuels m a de

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

accom m odations wastewater sam p les; therefore, the source of these analytes m a y be the sewage

CHT system

.

Tetrachloroethene was detected in three of five influent to treatm e nt system

sam p les. Tetrachloroethene is a solvent used in m e tal cleaning and dry cleaning (ATSDR, 1997).

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

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

accom m odations wastewater (or any other graywater sam p les); therefore, the source m a y be the

sewage CHT system

.

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

influent to the wastewater treatm e nt system

. To tal PCBs in the influent were m easured at a

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

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

been associated with electrical equipm ent, such as transform e rs; however, they have also been

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

detected PCBs have any known m a nufacturers. (Not e that PCBs were not analyzed for in source

water.)

Sim azine was the only pesticide detected in the influent to the treatm e nt system

.

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

weeds and annual grasses in fields, berry fruit, a nd vegetables. Sim azine is classified by EPA to

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

swim m i ng pools, hot tubs, and whirlpools. (Extoxnet, 1996)

# 4.1.3 Influent to the Ultraviolet (UV) Di sinfection Part of the Treatment System

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

part of the Island’s wastewater treatm e nt sy stem

. Grab sam p les for individual pathogen

indicator analyses were collected for five consecutive 24-hour sam p ling periods. Pathogen

indicators, which were generally in the m illions at the inf l uent to the treatm e nt system (see Table

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

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

final effluent (i.e., after the UV disinfecti on 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 treatm e nt system , which

was sam p led for five consecutive 24-hour sam p ling periods. Only those analytes detected at

least once in any of the wastewater sam p les (i.e., graywater sources, influent to treatm e nt

system , or effluent from treatm e nt 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 sam p les were collected for analysis of the three pathogen

indicators over the five 24-hour sam p ling periods (results and collection tim es for each grab

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

ef

f l uent f r om the treatm e nt system ; the exceptions to this were three grab sam p les in which E.

coli was detected at levels close to the detection lim it (one sam p le on Day 1 and two sam p les on

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

lim it (Day 1, Day 4, and Day 5), and one grab sam p le in which fecal coliform was detected at 20

CFU/100 m L on Day 1 (detection lim it is 2 CFU/100 m L ).

Thirteen of the 16 classical pollutants we re detected in effluent from treatm e nt

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

4-8

# detected in any effluent sam p les. Three of the 13 detected classical analytes were also detected

at som e level in the potable water used as source water for all graywater and sewage system s

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

water m a y have contributed som e or all of the analytes to the sam p le. None of these analytes

were detected in the equipm ent blank.

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

Island treatm e nt system are lower than EPA’s standards for secondary treatm e nt.

# Total and Dissolved Metals

Am ong the 54 total and dissolved m e tal analytes tested for, 31 were detected in

one or m o re effluent from treatm e nt sam p les (Tab le 4-8). Of these 31 detected m e tal analytes,

22 were detected in every effluent from treat m e nt sam p le. Eight of the 31 detected m e tal

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

see Table 5-2 for equipm ent blank results), m eaning that the sam p ling equipm ent m a y have

contributed som e or all of this analyte to the sam p les. EPA will consider the im pact of possible

contam ination from equipm ent in a future analyses. Seventeen of these detected m e tal analytes

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

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

m eaning that the source water m a y have contributed som e or all of the analytes to the sam p le.

The 10 m e tal analytes detected at the highest concentrations were total and

dissolved calcium , m a gnesium , sodium , zinc, a nd boron. Total and dissolved copper, nickel,

selenium , zinc, and total m e rcury are priority pollutant m e tals (designated by EPA in 40 CRF

4-9

# Part 423, Appendix A) that were detected in ever y effluent from treatm e nt sam p le. Som e m e tals

m a y results from contact with carbon steel and stai nless steel pipes and tanks in the ship. There

are no EPA secondary treatm e nt standards for m e tals.

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

Am ong the 84 target analytes for volatile and sem i volatile organics analyzed,

only two–phenol and bis(2-ethylhexyl)phthalate–wer e detected in any Island effluent sam p les

(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 som e level in the potable water used as source water for

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

water results), m eaning that the source water m a y have contributed som e or all of the analyte to

the sam p le.

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

from the treatm e nt system

.

4.1.5 Wastew a ter Treatment System Performance: Comparison of Influent to

Treatment System and Effluent from Treatment System

The Ham w orthy treatm e nt system successfully rem oved alm o st all pathogen

indicators (>99%; Table 4-9) and m o st classical po llutants, m e tals, and organics (Tables 4-9 and

4-10).

Pathogen Indicators and Classical Pollutants

Pathogen indicators were generally rem oved by the bioreactor and m e m b rane

f ilters to levels below detection (>99% rem oval), while any rem a ining indicators were generally

rem oved by UV disinfection (overall system effici ency >99%, see Table 4-9). Enterococci and

E. coli were each detected in 3 of the 15 effluent from treatm e nt sam p les at levels close to the

detection lim it; fecal coliform was detected in 1 of the 15 sam p les.

4-10

# The treatm e nt system rem oved alm o st all biochem i cal oxygen dem a nd (BOD

5 

# )

(99%), and m o st chem ical oxygen dem a nd (COD) (93%) and total organic carbon (TOC) (89%)

(Table 4-10). The system also rem oved alm o st all settleable residue and total suspended solids

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

below detection.

The treatm e nt system reduced am m onia by 58%, while reducing total Kjeldahl

nitrogen (TKN, which m easures both am m onia and organic form s of nitrogen) and total

phosphorus by approxim a tely 75% (Table 4-10). Nitrate/nitrite levels are low and rem a ined

relatively unchanged. Nitrogen is likely taken up by the m i croorganism s in the bioreactor and

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

nitrification (the m echanism of am m onia biodegrad ation) as nitrification would have resulted in

an increase in nitrate/nitrite concentration, but these levels rem a ined relatively unchanged.

Phosphorus also is m o st likely taken up by the m i croorganism s 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 m e tals analysis m easures both the particulate and dissolved form s of

m e tals, while the dissolved m e tals analysis m easures only the dissolved form

. The difference

between the total and dissolved m e tals m easurem ents is the particulate m e tals concentration.

Metals were present in both particulate and dissolved form s in the influent to the treatm e nt

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

m o st m e tal analytes) (Table 4-6). In com p arison, m e tals were predom inantly present in the

dissolved form in the effluent from the treatm e nt system (i.e., the total and dissolved m e tals

concentrations were sim ilar in these sam p les) (Table 4-8). Furtherm ore, there were elevated

m e tals concentrations in the screening solids and waste biosludge (see Table 4-11). This m e ans

that the treatm e nt system is highly efficient in rem oving particulate m e tals, as would be expected

for m e m b rane filtration (and as supported by $ 

# 99% rem oval of settleable residue and TSS, see

Table 4-8). The treatm e nt system s rem oved dissolved m e tals with an average efficiency of 37%

(Table 4-10).

4-11

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

The treatm e nt system was able to rem ove m o st of the volatile and sem i volatile

organic com pounds to levels below detection (Table 4-10). Possible rem oval m echanism s

include biological degradation, adsorption onto wa stewater treatm e nt sludge (see Table 4-11),

and/or volatilization.

Sim azine was the only pesticide detected in the inf l uent to treatm ent, and

pesticides were not analyzed for in the effluent from treatm e nt. W h ile PCBs were detected in the

influent to treatm e nt, they were not analyzed fo r in the effluent from treatm e nt. EPA has no data

regarding the perform a nce of the Ham w orthy treatm e nt system for rem oving pesticides and

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

treatm e nt system

. Dioxins and furans were an alyzed 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-tim e grab sam p les of

screening solids (from screens presses at the be ginning of the treatm e nt system ), waste biosludge

(excess biological m a ss from the treatm e nt system ’s bioreactor), and incinerator ash (from

incineration of trash, screening solids, and spent bag f ilters) collected during the sam p ling

episode. Table 4-11 also shows the average infl uent to treatm e nt analyte concentrations from

Table 4-10 for com p arison.

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

also detected in the influent to treatm e nt. For m a ny analytes, concentrations in the screening

solids and waste biosludge exceeded those in the influent to treatm e nt, suggesting that these

analytes are rem oved from the system in these waste stream s. See Section 4.1.5 for a detailed

discussion of wastewater treatm e nt system perform a nce.

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

approxim a tely two-thirds of freshwater requirem e nts and bunkered water providing

approxim a tely one-third of freshwater requirem e nts. Seven total m e tals, 11 dissolved m e tals, 3

classical pollutants, and 1 organic were detected in the one-tim e grab sam p le of potable water

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

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

detected in the source water sam p le.

4.2 Summary of Interview s Regarding Activities that Impact Wastew a ter

Generation

The ship’s crew was interviewed to obtain inf o rm ation regarding activities that

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

operational, discharge, and wastewater treatm e nt operating logs corresponding to the period of

the sam p ling episode. These docum ents are included in the Cruise Ship Rulem a king Record and

are available upon request.

4.2.1 Wastew a ter Generation

Galley

The Island has two m a in dining room s, four additional restaurants, and 24-hour

room service. Approxim a tely 10,000 m eals (breakfast, lunch, dinner, and snacks) are served

daily. The ship' s ten m a in autom a tic washing m achines operate 24-hours a day. Dishes are

washed using Solid Power and Super Trum p (high alkaline solid autom a tic dishm a chine

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

(MSDS) for these products are included in the Cruise Ship Rulem a king Record and are available

upon request.

4-13

# Laundry

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

linens from approxim a tely 0800 to 1500 and 2000 to 0100 each day. Cleaning agents (Laundri

SL-2000 and Eco-Star Detergent 1) are dispensed autom a tically using a com puter-controlled

m e nu depending on the m a terial and degree of soiling. The Island operates two large washing

m achines to wash blankets (total of 10 loads per day at 300 pound capacity each) and two sm all

washing m achines (50 pound capacity) to wash passengers’ personal item s (operate from

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

Cruise Ship Rulem a king Record and are available upon request. Finally, the Island has six

passenger laundrettes and six crew and officer laundrettes, processing approxim a tely 40 pounds

of laundry per load.

Photo Processing

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

equipm ent. All waste photographic chem icals are collected into drum s for disposal onshore. The

drum s are stored within secondary containm ent 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 chem icals 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 chem ical residues)

are disposed of as hazardous waste onshore.

4-14

# Dry Cleaning

The Island has a dry cleaning facility. One Renzacci dry cleaning m achine

processes approxim a tely f i ve loads per day using auto-distillation of solvent. This m achine

generated five liters of spent solvent during the first seven m onths 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 m achines process approxim a tely 15 loads

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

crew. Aquatex wastewater and lint waste is r outed to the laundry CHT system s. No sinks or

f l oor drains are present in the dry cleaning f acility.

Chemical Storage

Any spills f r om the engine room storage areas are captured in the bilge and do not

enter the graywater or sewage system s. See Appendix C for m o re inform ation on chem icals

stored in each engine room

. Chem icals are also stored in other room s of the ship as listed in

Appendix C; none of the storage room s have floor drains to ensure that spilled chem icals do not

enter the graywater and sewage system s.

Medical Infirmary

The Island has a m e dical infirm ary. W a ter that enters the floor drain or sinks

drains to the graywater system ; there is no floor drain in the digital im aging room

. Sinks are

used for handwashing only; the crew indicated th at no chem icals are disposed of in the sinks.

Any wastes are collected by the environm ental officer for onshore disposal.

4.2.2 Pesticide, Fungicide, and Rodenticide Use

The Island uses Siege Gel insecticide bait (active ingredient hydam e thylnon) and

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

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

4-15

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

Ship Rulem a king Record and are available upon request. The pesticide Sim a zine was detected

in one Island influent to treatm e nt sam p le. Sim azine is a selective herbicide used to control

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

industrial areas. In the past, Sim azine was used to control subm erged weeds and algae in large

aquarium s and swim m i ng 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 m e ters were used to collect flow m easurem ents and to

control autom a tic com posite sam p le m achines on (1) the outlet f r om the crew galley collection

tank, (2) the outlet from one of the accom m odations wastewater collection tanks, (3) the influent

to wastewater treatm e nt, (4) and the effluent from wastewater treatm e nt (see Section 2.4 and

Figures 2-1 and 2-2). The flow m e ters were pr ogram m e d to record the instantaneous flow rate

(m 3 

# /m in) and total f l ow (m 3 

# ) every five m i nutes. Flow data analyses presented in this section are

based on only those flow data collected during the sam p ling episode of August 28 through

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

23 through Septem ber 3.

The flow m e ters on the outlet pipes from the galley and accom m odations

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

operating, indicating significant backflow through these system s. Accordingly, the recorded

flows do not accurately represent galley and accom m odations wastewater generation at these

locations and are not described further in this report.

The total daily volum e of influent to and effluent from the treatm ent system for

each 24-hour sam p ling period are presented in Figur e 4-1. The influent to the treatm e nt system

flow was, on average, 75 percent of the flow m easured from the effluent from the treatm ent

system

. One possible explanation is that the ultrasonic signal to the flow m e ter at the influent to

4-16

# treatm e nt system was weakened (or scattered) by the am ount of solids present in the raw

wastewater flowing through the pipe. A com p ar ison of the average hourly flows indicates that

the influent and effluent discharge flow ra tes show sim ilar fluctuation throughout the day.

Therefore, the flow m easurem ents collected from the influent to the treatm e nt are probably valid

f

o r qualitative use. The total daily f l ow f r om the inf l uent rem a ined relatively constant over the

five-day sam p ling 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 treatm e nt system for part

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

wastewater to a holding tank for overboard discharg e 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 sam p ling episode, as reported by the ship’s

crew. On average, each person generated approxi m a tely 41 gallons of treated wastewater per

person per day. It is im portant to note that the treatm e nt system treats only accom m odations

wastewater and sewage. The f l ow m easurem ents do not ref l ect 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 treatm e nt flow for each hour

interval over the five consecutive 24-hour sam p ling periods, calculated from data collected via

the strap-on flow m e ter. The highest rate of overboard discharge occurs between the hours of

2100 and 0400.

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

sam p ling 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

Rulem a king 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 sam p ling episode include the analysis of m a trix

spikes, duplicate sam p les, and quality control standard checks.

5.1 Analytical Quality Control

EPA verified that laboratory performace was acceptable by conducting quality d

control checks o f the analytical data as specified by the QAPP. D ata review chem ists prepared

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

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

Appendix D and were excluded from the data set:

C 

# Three organics:

— 2 -Chloroethylvinyl ether in sam p les 65715, 65719, 65731, and

65741,

— H exachlorocyclopentadiene in sam p le 65719, and

— B enzidine in sam p le 65749.

C 

# E. coli , enterococci, and fecal coliform in sam p les 65731, 65733, and

65737;

5-1

# C 

# Biological oxygen dem a nd in sam p les 65607, 65627, 65647, 65667,

65707, and 65727; and

C 

# Settleable residue in sam p les 65607, 65627, 65647, 65667, 65707, and

65727.

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 sum m a ry tables in Section 4.1. Available

cyanide was detected in m a ny sam p les, while total cyanide was not detected in these sam p les. In

theory, the total cyanide result f o r any given sam p le will be greater than the available cyanide

results in the sam e sam p le. Because it was not possible to determ ine which analysis was correct,

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

problem s (see m em o randa 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 com p lete discussion).

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

onboard interviews regarding activities that im pact wastewater generation.

5.2 Field Quality Control

The trip blank, equipm ent blank, and fi eld duplicate results are the field QA/QC

m easures 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 f i eld QC sam p les during the sam p ling 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 f o r volatile organics to evaluate possible

contam ination during shipm e nt and handling of sam p les. This sam p le consisted of high

perform a nce liquid chrom a tography (HPLC) water. The trip blank was prepared prior to the

5-2

# start of the sam p ling episode, and accom p anied sam p les shipped to the laboratory on Septem ber

2, 2004.

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

contam ination of sam p les 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 sam p ling team collected an equipm ent blank to assess the potential

introduction of contam inants by sam p le collection equipm ent. The sam p le collection equipm ent

used to collect the equipm ent blank was the sam e as that used at the sam p ling points:

approxim a tely 4 feet of Teflon® tubing connect ed on one end to a series of m e tal plum bing

fixtures installed on each sam p le port, and the other end to a sm all segm ent of silicone tubing

used in the peristaltic pum p m echanism of the autom a tic sam p ler. The equipm ent blank was

collected by pum ping HPLC water through this equipm ent directly into sam p le bottles.

Table 5-2 presents the detected results for the equipm ent blank. Six total m e tals

and seven dissolved m e tals were detected in the equipm ent blank. In tables presenting the

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

indicate they were detected in the equipm ent blank. EPA will consider the im pact of possible

contam ination from equipm ent in a future analysis.

5.2.3 Field Duplicates

Field duplicate sam p les were collected to assess the precision of the entire sam p le

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

between the two duplicate sam p le results is calculated and com p ared to the data quality

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

than 30% for all analytes of a specific analytical m e thod.

5-3

# Classical Pollutants, Total and Dissolved Metals, and Semivolatile Organics

For classical pollutants, total and dissolved m e tals, and sem i volatile organics,

field duplicate sam p les were sam p les collected from the sam e source, at the sam e tim e, then

stored and analyzed independently. The duplicate sam p les were collected as split sam p les

poured from the sam e m i xed sam p le com posite jars to m i nim i ze sam p le wastestream variability.

Duplicate sam p les for these analytes were coll ected from the effluent from the wastewater

treatm e nt system (SP-6/7). Note that duplicat e sam p les for dioxin and furans and pesticide

analytes were collected during a previous sam p ling episode, and duplicate sam p les for

HEM/SGT-HEM were not planned for this sam p ling program

.

Table 5-3 presents analytical results and the RPDs for these duplicate sam p les and

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

sam p les during the sam p ling episode.

There was excellent precision in sam p ling and analysis for this sam p ling 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 sam p les were less than the detection lim it.

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

in one sam p le but not the other. Analytical variability increases as analyte concentrations

approach their detection lim its. 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 alum inum , total iron,

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

three duplicate pairs for total m e rcury, and three of four duplicate pairs for dissolved selenium

.

These results are not uncom m on in com p lex wastewater sam p les.

In tables presenting the analytical results in Section 4.1, duplicate sam p le results

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

5-4

# Pathogen Indicators and Volatile Organics

For pathogen indicators and volatile organics, field duplicate sam p les were

collected sequentially and not as split sam p les as was done for the other analytes. For these

sam p les, this m e thodology introduced sam p le wastestream variability into the assessm ent of the

precision of sam p le collection and analysis. Duplicate sam p les for these analytes were collected

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

the RPDs for these duplicate sam p les. Of the 42 duplicate pairs, 41 either achieved the RPD

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

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

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

analyte concentrations approach their detection lim its.

In tables presenting the analytical results in Section 4.1, duplicate sam p le results

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

of pathogen indicators, average daily results presented incorporate both duplicate grab sam p les

and m u ltiple grab sam p les collected for individual analysis during each 24-hour sam p ling period.

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

sam p le results for that sam p le (e.g., grab 1 duplicate sam p le results for Day 3 were averaged

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

sam p le results for each day were averaged to calculate the average daily pathogen indicators

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

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

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

day, rather than weighted m o re heavily by the particular tim e of day when duplicate grab

sam p les were collected.
