Groundwater Monitoring Plan

For Final Effluent Ponds 1 and 2

BWX Technologies, Inc Naval Nuclear Fuel Division

February 6, 2001

ADMINISTRATIVE REVIEW OATE
The Final Effluent Ponds are located north and east of the wastewater treatment plant. FEP 1 has

a 1.2 million-gallon capacity and FEP

2 has

a 1.8 million-gallon capacity. FEP I was placed in service in 1973 and received wastewater from both the low-level radioactive (LLR) and pickle acid treatment systems until 1979. Both waste streams are neutralized via separate systems and the precipitation solids are removed by filtration. Suspended solids from both neutralization operations are carried over into the FEPs. In 1979, FEP 1 was drained and approximately 50 percent of its sludge was placed into FEP 2. From 1979 to 1992, FEP 1 received wastewater from the pickle acid and sanitary treatment processes. From 1979 to present, FEP 1 has received wastewater from the imhoff treatment process. FEP

2 received LLR wastewater from 1979 to present, and pickle acid wastewater from 1992 to present.

In November 1990, The Virginia Department of Environmental Quality classified the pickle acid waste stream as a chemical etching/milling operation. Consequently, the neutralization sludges generated from treatment were classified as EPA Hazardous Waste No. F006. Both FEPs have received wastewater from the pickle acid system and suspended solids from the neutralization operation have been deposited in each pond. It should be noted that current generation of this sludge has been delisted by USEPA and Virginia DEQ.

3.0 Groundwater Monitoring System

The groundwater monitoring system currently in place consists of one upgradient well and three wells immediately downgradient of the FEPs. The monitoring well locations are shown on Figure 1. The groundwater flow has been established (from a previous RCRA Facility Investigation) to be flowing in

a northeasterly direction towards the James River.

Borings for the monitoring wells were drilled using hollow-stem auger methods.

A borehole diameter of 7 1⁄4 inches was drilled to install the 2-inch schedule 40 PVC casing and screen. The 0.0 10 inch slotted screen was installed at

a depth, where lithology permitted, from approximately 10 feet below the water table to 5 feet above the water table. The screened portion of each well was packed with

a sand pack.

A 1-foot hentonite seal and a 2-foot cement grout seal were then added, completing the well to the ground surface. The wells were completed with aboveground locking steel protective casings and

• Intended uses for the data

• Precision, accuracy, representativeness, and completeness

• Data comparability

• Quality assurance (QA) reports and schedules

• Analytical data quality levels.

Data quality levels that will be needed for this compliance sampling include Level 1 (field screening or analysis using portable instruments), in an analytical laboratory). and Level 3 (analyses performed

All analyzed using one ofthe suggested SW-846 methods sample analysis procedures and requirements are specified in detail in the DCQAP. The DCQAP provides details for the following requirements that apply to the compliance sampling effort:

• Surrogate spike response evaluation.

To ensure the reliability of field sampling procedures and materials, will be collected or prepared. The field QC samples will be collected during implementation following paragraphs describe the QC samples that of this plan.

3
Equipment rinsates will be collected during sampling to verify the effectiveness of sampling equipment cleaning and to monitor for potential to inadvertently transport constituents of interest between samples. Equipment rinsates will be collected from the final deionized water rinses of the equipment. One rinsate will be collected from each site. The rinsates will be analyzed for the same analytes as the samples collected that day.

5.3 Field Blanks

Field blanks are prepared from the laboratory-grade-deionized water used for cleaning. Analysis of field blanks will ensure that all water sources used during cleaning of sampling equipment are free of the parameters of interest. At a minimum, one sample will be collected for every sampling event day and analyzed for VOCs.

5.4 Field Duplicates

Duplicates for samples will be collected simultaneously with the original samples. For each sample type, one field duplicate will be collected during the field event. To meet the analytical QC requirements, the field duplicates will also be selected as the laboratory matrix spike/matrix spike duplicate pair and the laboratory duplicate sample. Therefore, at least four times the minimum required sample volume will be collected and four different analyses will be performed: the original sample, the field duplicate, the laboratory matrix spike, and the laboratory matrix spike duplicate or 1abortory duplicate.

5.5 Field Equipment Calibration

Field instrument calibration is required to maintain accuracy of the instruments for conducting field screening, measurements, and health and safety monitoring. Calibration readings and procedures will be recorded. Field instruments will be calibrated as stipulated below; operations manuals for all instruments will be maintained on site with the sampling equipment:

• pH meter -Calibration as specified by the manufacturer, prior to each shift or break.

• Specific conductance meter -Calibration as specified by the manufacturer, prior to each shift or break

th procedures appropriate for

the intended use of the data

• Data will be of known and acceptable precision, accuracy, completeness,

representativeness, and comparability.

Fundamental mechanisms that will be employed to achieve these quality goals can be

categorized as prevehtion, assessment, and correction. These include:

• Prevention of errors by planning, documented instructions and procedures, and

careful selection and training of skilled, qualified personnel

• Quality assessment through a program c-f audits and surveillances to supplement

continual informal review

• Correction for prevention of recurrence of conditions adverse to quality.

The DCQAP has been prepared in direct response to these goals. This plan describes the

QA program to be implemented and the quality control (QC) procedures to be followed by

BWX Technologies (BWXT) and its contractors during the course any sampling events

conducted at the BWXT Mt. Athos site. - 1,1 intended Uses for the DataData obtained from any sampling event may be used to characterize the site’s environmental

setting, define and characterize the nature and extent of the potential release of hazardous

waste or hazardous constituents from the areas of investigation at the site, identify actual or

potential receptors, and perform a risk assessment.

I —I
specified for the selected methods.

This DCQAP has been prepared in direct response to these goals. The remaining sections of

the plan describe the QA procedures to be implemented and the procedures to be followed

by BWXT and its contractors during the course of a sampling event. These procedures will

also:

• Maintain the necessary level of quality of each aspect of the analytical program by

providing the appropriate level of verification, testing, checking, and statistical

analysis of the laboratory program procedures

• Assist in the early recognition of factors that may adversely affect the quality of

data and provide for the implementation of procedures to correct these adverse

effects

• Enhance the utility of all data produced by the laboratory for decision-making

purposes by requ!nng sufficient documentation of the testing process. lnformation

on the limitations of the analytical results will be included in the documentation.

Information on data usage and data quality objective (DQO) levels is included in Table 1-1.

The table shows the intended uses of the data for the various analytical techniques andsample matrices, together with the appropriate analytical levels. These levels are:

• Level I - Field screening or analysis using portable instruments

• Level II - Field analysis using more sophisticated portable analytical instruments

(possibly in a mobile laboratory)

1-2
ed and reported in units consistent with the SW-846, 3rd ed. analytical procedures

to allow for comparability. Definitions for and means of assessing precision, accuracy,

completeness, representativeness, and comparability are described below:

• Precision -A measure of agreement among replicate measurements of a sample.

Comparison of replicate values is expressed as the relative standard deviation

(RSD).

• Bias -Consistent deviation of a measured value from the true value caused by a

systematic error in procedure.

• Accuracy -The degree of agreement of a measurement (or an average of replicate

measurements), X, with an accepted reference or true value, T, usually expressed

as the difference between the two values, X-T, or the difference as a percentage of

the reference or true value, 100 (X-T)/T, and sometimes expressed as a ratio, XIT.

Accuracy is a measure of bias and precision.

Accuracy is assessed through the analysis of spiked samples, known standards, and reference samples.

• Completeness -A measure of the amount of valid data obtained from a

measurement system compared to the amount that was expected to be obtainedunder correct normal conditions. This QA criterion is expressed as a percentage.

The completeness for sample collection will be 95 percent or better. Thedata completeness will be 100 percent for residential well samples and 90 percent

or better for other types of samples.

• Representativeness - Expresses the degree to which data accurately and precisely represent a characteristic of a population, parameter variations at a sampling point,

:1-3
1.3 Data Comparability

One of the objectives of the DCQAP is to provide analytical data of comparable quality

between sample locations and with data from previous investigations. ComparahiUty is a

qualitative criterion measuring the confidence with which one set of data can be compared toanother. For this project, the data comparability will be achieved by the following:

• Analytical results will be reported in appropriate units: ugll and mg/I for aqueous samples, and mg/kg for soil samples.

• The same or similar sampling procedures used in previous investigations will be used.

• The same or equivalent analytical procedures used for previous investigations will be used.

• Similar QAIQC requirements will be observed.

The BWXS—NEL’s quality assurance is documented in NELS-QAP, N&EO QIP, and the

NELS TP. The plans and standard operating procedures have been used by BWXT to

conduct the sampling and analysis from previous investigations and ongoing quarterly

sampling. BWXT has also used outside laboratories to provide confirmatory and supportanalyses. The same sample collection techniques and analytical procedures will be used to

maximize the comparability of data with previous investigations. Additionally, to enhance

comparability between samples, consideration will be given to seasonal conditions, stream

flow, or other environmental conditions that could influence the analytical results.

from groundwater monitoring wells. In addition, water samples may be collected from

creeks that originate on the facility property and flow into the James River, as well as

the river. Soil samples may be collected from borings to investigate vadose soil

characteristics. Sediment samples may be collected from selected ponds and creeks

at the facility. Sludge samples may be collected from current and historic waste

disposal sites at the facility.

2.2 Soil BoringsSoil borings may be drilled for the collection of soil samples to determine the

characteristics of the soil in the vadose zone.

Soil borings will be advanced using the hollow-stem auger method in accordance with

American Society for Testing and Materials (ASTM)-1452-80 and logged in

accordance with ASTM D1452-85 using the Unified Soil Classification System

(USCS). During advancement of the boreholes, a 5-foot long, 2-inch diameter steel

split-barrel sampler will be used to correct soil samples. Soil samples will becontnuousv collected from the surface to the total depth of the boring. The entire

length of the sample collected from the sampler may be field screened for the

presence of organic vapors, as described in Section 2.2.1 and for visual classification

of the soil. Soil samples will be retained until the boring is completed. Uponcompletion of the boring, soil samples will be submitted for laboratory analysis based

on the results of the field screening for organic vapors (if any), visual evidence ofcontamination or alteration, other criteria as determined by the on-site geologist based

on the conditions encountered, or as directed by the BWXT cognizant engineer. Thecriteria for sample selection will be documented on the field activity daily log. A

sufficient number of additional samples will be collected as necessary to fully

.

2-1
All soil cuttings generated during the drilling of soil borings will be stockpiled on plastic

sheeting, bermed, and covered with plastic sheeting within the study area where the

borings were drilled. Upon receiving the laboratory analytical results from the samples

collected from the borings, the disposition of the soils will be determined. Those soils

found to be above regulatory action limits for any of the constituents of analysis will be

disposed of in compliance with state and federal regulations. Those soils found to be

below action limits will be spread across the ground surface in the area where the

borings were installed.

22.1 Field Screening of Soil Samples

If filed screening is deemed necessary, the 5-foot sample barrel from the boring will be

placed on clean plastic sheeting and the barrel split open. The entire length of the

sample will then be scanned for the presence of organic vapors using an HNu or

similar photoionization device. The depth interval and reading in units of parts per

million will be recorded for any portion of the sample where organic vapors are

detected. The sample will also be visually observed for any signs of alteration or

contamination and the observations noted. The measurement of volatile emissions or

significant visual observations will serve as a qualitative indication of potential

contamination.

In areas of known or suspected acid releases, soil samples will be collected and

submitted for laboratory measurement of pH. Low pH readings will serve as a

qualitative indicator of acid impacted soils.

the completion of the hole. Upon completion of each boring, soil samples will be

selected for laboratory analysis. The minimum number of samples selected and the

specific laboratory analyses to be performed will be specified in the area-specific filed

sampling plan.

2.2.3 Soil Samples for Geotechnical Analysis

In selected borings, soil samples will be collected for analysis of the geotechnical

parameters if required. The specific soil horizons to be sampled will be selected by

the field geologist during drilling operations based on visual inspection or geologic data

obtained from previous boreholes in the area. Soil samples for geotechnical analysis

will be collected by pushing a Shelby tube into the soil. Upon retrieval, the tube shall

be sealed with end caps, taped, and sent to a laboratory for analysis.

2.2.4 Borehole Abandonment

Boreholes not used for the installation of monitoring wells will be backfired with a 5

percent bentonite/cement grout. The boreholes will be grouted with this mixture from

the bottom to the top of the borehole using a tremmie pipe method as the hollow-stem

augers are being removed from the borehole. The grout will be allowed to settle

overnight and will be topped off the following day, if necessary, to compensate for any

settling that may have occurred.

2.3 Sediment Sample Collection

Sediment samples obtained from streams will be collected with a stainless steel trowel

or scoop sampling device. Any excess liquid will be decanted from the sediment

sample before placing it in the appropriate sample container. Sediment samples will

be placed in the appropriate containers for each analysis to be performed as specified
Sediment samples taken from ponds will be collected using a 

yp

p,

such as an Eckman Dredge or similar sampling device. The sampler will be used to

collect a sample from the upper sediment layer by the following procedure:

• Sample line will be attached to the pre-cleaned Eckman Dredge.

• The distance from water surface to bottom will be measured and marked so

that the equipment-lowering rate can be reduced, thus preventing

unnecessary bottom disturbance.

• The sampler jaws will be opened by attaching the support cables to the

messenger tripping mechanism.

• The free end of the sample line will be tied to a fixed support to prevent

accidental loss of the sampler.

• The sampler will be lowered more slowly as the bottom depth approaches.

• Once contact with the bottom is made, the sample line will be slackened to

allow the sampler to penetrate into the sediment.

• The messenger, which slips around the sample line, will be released and will

trigger the closing of the dredge.

• The dredge wiJI slowly be raised to the surface.

• Using a stainless steel spoon, the sample will be removed from the dredge

and placed inside an appropriate sample container.

Samples collected will be handled as described for stream sediment samples. The

sampler will be thoroughly cleaned between sampling events.

2-4
bedrock monitoring wells will be drilled using an air rotary drilling rig. Bedrock borings

win be advanced using a 9-1/4inch-drill bit. Upon encountering bedrock, a temporary

casing will be placed in the boring to prevent the sidewalls from collapsing. Boreholes

for the installation of surficial aquifer wells will be drilled approximately 10 feet below

the water table.

Deep wells to be completed in bedrock will be drilled 5 to 10 feet into the bedrock, and

a 6-1/4inch-diameter polyvinyl chloride (PVC) casing will be installed and grouted into

place. The grout will be allowed to solidify for no less than 24 hours. This procedure

will be followed to prevent potential mixing of the surficial and bedrock aquifer waters.

After 24 hours, the well will be drilled to total depth through the 6-1/4-inch casing using

a 6-inch drill bit. A boring log will be prepared for each well to describe the lithology

encountered. All PVC casing will conform to the requirements of ASTM-F480-81,

D1785. All PVC screen and casing construction joints shall be flush threaded. No

glued or solvent welded joints shall be permitted.

• Cuttings generated during the driiiin of borings for the intaliation o monitoring wells

may be field screened for the presence of organic vapors using an HNu

photolonization device. Those cuttings exhibiting organic vapors will be stockpiled on

plastic sheeting, bermed, and covered with plastic sheeting.

All water and fluids generated during the drilling and completion of the wells will be

contained and disposed of by being pumped into the pickling wastewater treatment

system at the Naval Nuclear Fuel Division (NNFD) plant.

2-5
water-bearing zone using a 15-foot length of well screen. The annulus around each

well screen will be backfired with clean, well-graded silica sand using a tremmie pipe.

The sand pack will extend to approximately 2 feet above the well screen. A 2-foot

layer of bentonite pellets will be placed directly above the sand pack. Bentonite pellets

will be emplaced with a tremie pipe in wells deeper than 30 feet, and a tamping device

used to pack the pellets in wells less than 30 feet deep. The remainder of the annulus

will be filled with a bentonite/cement grout. The wells will be finished with concrete

pads and locking caps.

Monitoring wells installed within the bedrock aquifer will be drilled 5 to 10 feet into the

bedrock, and a 6-1/4-inch permanent PVC surface casing will be grouted into place.

The grout will be allowed to solidify for no less than 24 hours. This procedure will be

followed to prevent the mixing of surficial and bedrock aquifer waters. After the grout

has solidified, the boring will be drilled to total depth through the surface casing.

Monitoring wells drilled to depths greater than 100 feet below the bedrock surface will

be completed as open holes below the surface casing without well casing. All

V shallower wells wifl be completed witn WC!i casing as specified ac The WOS Wii

be finished with concrete pads and locking well caps.

2.4.3 Well Development

Each newly installed groundwater monitoring well will be developed no sooner than 24

hours after completion. The wells will be developed by pumping. Surging of the pump

will be performed during well development to prevent bridging. The well pump shall be

properly cleaned before it is inserted in any well, as specified in Section 2.7.

Development water will be pumped into 55-gallon drums and labeled. The drums will

V
water are obtained. Readings of the above parameters will be taken at approximately

1 5-minute intervals. Those wells with low water yields will be developed until at least

three boring volumes are removed, or until the well is pumped dry.

2.4.4 Aquifer Testing

Permeability tests will be run on all monitoring wells installed. The’method used to

ran the tests in wells installed in the surficial aquifer will involve placing an electric

submersible pump into the well, measuring the static water level, and pumping the

well at a known and constant rate while measuring the dropping water level. Whenthe water level in the well drops below the pump, the pump will be disconnected from

the power source and the recovering water level will be measured at recorded time

increments until the level reaches its static elevation. A semilogarithmic plot will beprepared for each well data set to graph the change in head in the water level versus

the duration of elapsed time since the pump was started and the time since the pump

was disconnected. From these plots, the hydraulic conductivity (K) of the aquifer will

be cculated For deep bedrock aquifer welis withopen hole completions, aninflatable packer will be used if determined necessary by the field geologists to

isolate individual water bearing zones as identified from the borehole drilling logs.

The specific water-bearing zones to be tested and the number of tests will be

determined by the geologist in the field based on the data collected during the drilling

and testing of the boring. As with the shallow aquifer wells, an electric pump will be

used to draw the water level down. The water level drawdown and recovery rates will

be measured and utilized to determine the hydraulic conductivity of the specific

water-bearing zones. All water removed from the well during aquifer testing will be

2-7
surveyed by a registered Virginia surveyor. Horizontal coordinates for all new

monitoring wells win be measured to the nearest 1 .0 foot and referenced to the 1929National Geodetic Vertical Datum (NGVD). Surface elevations for soil borings will be

determined to the nearest 0.1 foot. Elevation measurements will be made at the top

of the well casing and at the ground surface at each well. Elevations will bemeasured to the nearest 0.01-foot. The measurement point on the casing will be

clearly and permanently marked for future water level measurements. The locationson the pad will also be marked. The unique monitoring well identification number willbe permanently mounted to the protective cover.

2.5 Groundwater Sampling

The groundwater sampling procedures are based on US. EPA guidelines as

specified in the Resource Conservation and Recovery Act Groundwater Monitoring

Technical Enforcement Guidance Document (RCRA, 1986). Sample handling,

packaging, shipping, and chain-of-custody (COC) procedures will be consistent with

current U.S. EPA guidelines.

Before groundwater sampling, static water level elevation measurements shall be

taken in the well using an electric water level indicator. The water level shall be

measured to the nearest 0.01 foot and recorded in a field logbook.

2.5.1 Well Purging

Before being sampled, each monitoring well shall be purged of three boring volumes

of water or until the well is dry with a submersible purge pump or stainless steel or

Teflon bailer. The purging equipment shall be cleaned before and after the sampling

of each well. Wastewater produced during purging and sampling operations shall be

2-8
a reasonable time to recover. Water samples for chemical analysis will be collected

within 24 hours of purging operations.

2.5.2 Sampling Methods for Monitoring Wells

The groundwater samples from monitoring wells will be collected by means of a

dedicated bladder pump or clean stainless steel or Teflon bailer. When bailers areused, new polypropylene line will be used for each well. After purging, the first water

sample obtained will be tested in the field for pH, conductivity, and temperature

following EPA protocol as described in the NELS QAP and NELS TP. Subsequent

samples for laboratory analysis will be collected at a slow flow rate to minimize

agitation and aeration and preserved as specified in the applicable SW-846 method for

each analyte. Chain-of-custody forms will be prepared, samples will be labeled, and

stored in a cooler with adequate ice until delivery to the laboratory at the end of eachday. The temperature of contents of the cooler will be noted as equilibrium is reached

to insure 4°C storage. If dissolved metals analysis is desired, the samples shall befiltered in the field as soon as possible.

2.5.3 Water Supply Well Sampling

For water supply wells, including potable water wells, samples will be collected from a

faucet or valve near the well discharge point. If possible, samples will be collected

before the water goes through any type of filter system that maybe in use at thatlocation. Before any samples are collected from domestic wells, the pump will bepermitted to run for approximately 15 minutes to ensure that a fresh groundwater

sample is collected. Water supply samples will be placed in the appropriate labeledsample containers and stored in a cooler with ice until they are delivered to the

laboratory.

2.7 C’eaning Procedures

All drilling equipment that may contact the interior of the borehole, as well as all well

completion materials, shall be thoroughly steam-cleaned in a clean area free of

contamination designated by the field coordinator. After steam cleaning, all equipment

will be washed with a laboratory-grade detergent, followed by a Dl water rinse. Drilling

equipment will be thoroughly decontaminated and inspected between each drilling

location. All equipment used for groundwater and soil sampling, well purging, and well

development (including aquifer testing) will be washed with laboratory-grade

detergent, rinsed with tap water, rinsed with laboratory grade methanol, and rinsed

with Dl water and allowed to air dry. The cleaning area shall be lined with plastic and

shall have raised edges to contain all cleaning solutions and material dislodged from

equipment during cleaning operations. The materials collected at the cleaning area

(drill cuttings, soil sample debris, and other potentially hazardous solid waste) shall be

placed in labeled drums and disposed of in accordance with state and federal

guidelines.

Pre-cleaned bottles will be used for all analyses. Sample bottles will be cleaned

according to standard EPA procedures for each analysis type.

start time, weather conditions, all field personnel present, level of personnel protection

being used on site, the signature of the person making the entry, and other details will

be entered as specified. The names of visitors to the site and the purpose of their visit

may be recorded. All entries will be made in permanent ink; no erasures will be

allowed. If an incorrect entry is made, the information will be crossed out and initialed.

Measurements made and samples collected will be recorded. Equipment used to

make measurements will be identified, along with the date of last calibration. Samples

will be collected following the procedures documented in this pan. The equipment

used to collect samples will be noted, along with the time of sampling, the sample

description, the depth at which the sample was collected, and the volume and number

of containers in which the sample was placed in the field. Results of any gas or vapor

monitoring activities will be recorded. Major activities being performed or other items

pertinent to the history of the investigation will also be noted.

2.8.2 Boring Logs

The site geologist will maintain a detailed boring log during the drilling of each

borehole. The log will serve as a record of sample collection, sample location and

depth, and drilling procedures. The boring log will include:

2-12

284 Chain of Custody

The CCC procedures are intended to document sample possession from the time of

collection to disposal, in accordance with federal guidelines. Sample collection and

coc in the field will be documented in the field activity logs and on a COO form as

shown in Figure 2-1. This COO form will indicate the analyses required for each

sample as specified by the project plan. While in the laboratory, the CCC information

for all samples will be recorded on the laboratory’s internal CCC forms.

The criteria for maintaining custody requires that thioughout the sampling and analysis

process the samples and associated paper work are controlled in a manner designed

to prevent unauthorized tampering that could affect reported results while providing a

traceable record of sample handling.

2-14
each sampling event. This field investigation will be considered one event unless fieldpersonnel leave the site for more than 24 hours during the course of the investigation.

The following information defines and describes how to identify and document QC

samples. All field samples will be given unique sample numbers.

2.9.1.1 Trip Blanks

Trip blanks are defined as samples that originate from laboratory-grade Dl water taken

from the laboratory to the sampling site and returned to the laboratory with the volatileorganic samples.

The trip blank monitors potential cross contamination of the samples for volatiles

during handling and shipment. One trip blank shall accompany each cooler containing

samples to be analyzed for VOCS, shall be stored at the laboratory with the samples,

and shall be analyzed by the laboratory. Trip blanks only need to be analyzed for

VOCS. Trip blanks shall be identified with a unique number and the prefix ‘1TB’ on the

sample bottle and COO

2.9.1.2 Equipment Rinsates

Equipment rinsates will be collected during soil and groundwater sampling to verify the

effectiveness of sampling equipment cleaning and to monitor for potential cross

contamination between samples. Equipment rinsates are collected from the final Dl

water rinses of the equipment cleaning process. One equipment rinsate will be

collected from each site. The rinsates will be analyzed for the same analytes as the

2-15
Analysis of field blanks will ensure tha

a

wa

g 

sampling equipment are free of the parameters of interest. Only water field blanks are

required. At a minimum, one sample will be collected every other day of multi-day

sampling events or one sample collected during single day sampling events. Field

blanks will be analyzed for all parameters. Field blanks will be identified by a unique

number and the prefix “FB” on the sample bottle and COO.

2.9.1.4 Field Duplicates

Duplicates for samples will be collected simultaneously with the original samples. For

each sample type, field duplicates will be collected for at least 10 percent of the

samples collected during the field event. A minimum of one duplicate will be collected

per sample type. To meet the analytical QC requirements, at least half of those

samples selected as field duplicates will also be selected as the laboratory matrix

spike duplicate (MSD) pair or the matrix spike (MS) sample and laboratory duplicate

sample for a total of 5 percent of the field samples. Therefore, for half of the field

duplicates, at least four times the minimum required sample volume will be collected

and four different analyses will be pcrformed: the original sample,the field dulicate...

the laboratory MS, and the laboratory MSD or laboratory duplicate. For the remainder

of the field duplicates, two times the normal sample volume will be collected to provide

the original and the duplicate samples. Field duplicates will be identified with unique

sample numbers. The two samples collected as laboratory QC samples will also be

identified with unique sample numbers.

2.9.2 Field Equipment Preventive Maintenance

Preventive maintenance of equipment is essential if project resources are to be usedc’--effectivelv. Preventive maintenance will take two forms: (1) a schedule of

2-16
equipment is operating properly. On site electronics personnel will perform minor

repairs and purchasing will order parts overnight as necessary. Spare parts will bemaintained as appropriate. The lab equipment supplier will provide a back-up unit

within 24 hours should off-site repair be necessary. The lab has spare equipment,which typically includes pH and specific conductivity meters, calibrated thermometers,

and organic vapor meters. Parts for these are maintained by the manufacturer and

can be obtained overnight.

2.9.3 Field Equipment Calibration

This section establishes the procedures for maintaining the accuracy of instruments

and measuring equipment used to conduct field screening analyses, field

measurements, and health and safety monitoring. Calibration readings and

procedures will be documented in the field logbook.

4.3 Analysis Procedures for Soil, Groundwater, Surface Water, and Sediment Samples

Inorganic and organic analyses will be performed as specified in the SW-846, 3rd ed.,

using standard laboratory operating procedures. These include QAIQC requirements,

holding times, data qualifiers, and data reporting format.

4.4 Laboratory Quality Control Checks

Laboratory QC checks are used to validate data integrity. Analytical quality controls

are related to batches of semples a specified in SW-846 and the NELS QAP. These

4-3
methods and the NELS technical procedures. Surrogate spikes for organics shall also

be evaluated against the acceptance limits as specified in the appropriate SW-846

methods and the NELS technical procedures.

4.5 Documentation of Data

Documentation measures encompass all analytical and QC activities ensuring the

integrity and validity of sample analysis results and providing a traceable history of

each sample analysis. Information is recorded on worksheets, analytical logbooks, or

computer data systems. System support information such as instrument maintenance

and equipment calibration records are kept in laboratory files. Component analytical

documentation measures included are summarized in the following sections4.51 Laboratory Sample Receipt Logbook

All samples submitted to NELS for laboratory analysis are assigned a unique SDG

Number and each container/bottles is labeled with a unique identifier. All relevant

information regarding the origination and receipt of the samples is recorded in the

NELS’s electronic Sample Tracking System. Examples of the types of individual

entries include: analyses requested, date/time of coflection, receipt conditions, and the

filed identification number.

4.5.2 Laboratory Worksheets

The analytical specifications and subsequent results of each sample submitted to the

laboratory are recorded on various laboratory worksheets included in standard

operating procedures. Pertinent information on the worksheets includes laboratory

sample identification, requested analytical parameters, maximum holding times and

4-4
documentation employed by NELS allow for complete traceability of all the data

generated during the course of analysis.

4.5.4 Calibration Standards Logbook

4.5.5 Instrument Computer Data System FilesChromatography and atomic absorption spectroscopy data files are maintained

according to sample log number. The data files include instrument parameters,

calibration data, date of analysis, analyst, and QC results.

4-5
accomplished through instrument calibration with traceable standards and

collaborative testing such as blind performance evaluation (PE) and daily QC

samples. Raw data entries are validated by the analyst with a signature, date, and

time of analysis. The sample data packages include relevant information such as

sample identification, chain-of-custody, measurement methodology, instrument

identification, calibration data, analyst signature (with date and time of analysis), and

demonstration of statistical control with method blanks, field and trip blanks,

replicates, QC samples, and spikes (surrogates for organics). The laboratory

supervisor or designee oversees data collection and reduction to verify that data is

converted to meaningful reporting values. Consideration in data reduction must be

given to significant figures for each analysis, method detection limits, precision of

duplicate results, and the accuracy of QC data. Reporting of lab data by computer is

validated by signature of a cognizant individual. Reports will include sample

identification, final sample results, and QC information.

5.1 Data Assessment Protocol

When the analyses of a sample set are completed, the results are reviewed and

evaluated to assess the validity of the data set. Review is based on the following

criteria.

5.1.1 Sampling and Field Information

The sampling requirements are defined in the sampling plan. Field data are recorded

in field logs and may include as appropriate; well installation, field conditions, well

water sampling, field instrument calibrations, and field measurements.

5..
laboratory should take corrective action to locate and reduce the source of the

contamination and re-extract and reanalyze any samples associated with the

contaminated blank.5.1.3 Field and Trip Blank Evaluation

Field and trip blank results are evaluated for high readings similar to the reagent

and/or method blanks described above. If high field blank readings are encountered,

the procedures for sample collection, shipment, and laboratory analysis should be

reviewed. If both the reagent and/or method blanks and the field blanks exhibit

significant background contamination, the source of contamination is probably within

the laboratory. High field blank readings may also be due to airborne contamination or

cross contamination due to sample leakage and poorly sealed sample containers.

5.1.4 Method Calibration Evaluation

When evaluating calibration standards, the calibration curve is evaluated to determine

linearity through its fall range and. tp verify th?t sample values are within the range

defined by the low and high standards. If the curve is not linear, sample values must

be corrected for nonlinearity by deriving sample concentrations from a graph or by

using an appropriate algorithm to fit a nonlinear curve to the standards.

Calibrations are verified using both initial and continuing calibration check standards.

Acceptability of the calibration is based on the criteria set for each analytical method.

5-2
corrective action may include reanalysis.

MS/MSD pairs may also be assigned. The results of the duplicate analyses are used

to calculate the RPD, which is the governing QC parameter for precision.

The RPD for replicate analyses is defined as the absolute difference (range) of each

replicate set, divided by the average value (mean) of the replicate set, times 100

percent. For replicate results, D, and D2, the RPD is calculated as follows:

RPD— IDI-0211 xlOO%

(Di+D 2)/2

5.1.6 Evaluation of Analytical Accuracy

In addition to the evaluation of analytical precision, the laboratory will evaluate

accuracy. To determine the accuracy of an analytical the results of MS, MSD, and

blank spikes are used to calculate the QC parameter for accuracy evaluation, the %R.

The %R is defined as the observed concentration, minus The sample concentiaticn,

divided by the true concentration of the spike, times 1 00 percent:

01. 02

%R xlOO%

T1

where:

%R = Percent recovery

Ci = Observed spike sample concentration02 = Sample concentration

5-3
• Completeness -Results for all parameters requested are present; detection

limits, units, dates, and sample descriptions are complete and correct.

• Consistency - All parameters are reviewed for internal consistency.

• Accuracy of data entry.

5t7 Matrix Spike Evaluation

To evaluate the matrix effect of the sample upon the analytical methodology, samples

are spiked with compounds appropriate for the method. The % recovery of those

compounds from the sample is monitored.. Recovery limits are statistically

established for each method. If the % recovery is outside the acceptance range, an

evaluation of the cause of the deviation is undertaken. If it is determined that the

analytical system was out of control then the samples will be reanalyzed.

51.8 Reference Standard EvaluationStandard reference materials analyses are compared with true values and

acceptable ranges. Values outside the acceptable ranges require corrective actions

to determine the source of error and to provide corrective action. All sample

analyses should be halted pending this evaluation.

Following correction of the problem, the standard reference material should be

reanalyzed.

5.1.9 Surrogate Spike Response Evaluation

Surrogate standard determinations are performed on samples and blanks. Samples

and blanks are fortified with surrogate spiking compounds before purging or extraction

to monitor preparation and analysis of samples.

5-4
If recovery is of w

t

g

y 

ts, the following actions a

e ta

e

:

• Check for errors in the calculations, internal standard or surrogate spiking

solutions. Examine chromatograms for interfering peaks and integrated peakareas.

o Check instrument performance. Correct any problems and re-analyze the

extract. -

• If no instrument problem is found, the sample should be re-extracted and

reanalyzed.

• If, upon reanalysis, the recovery is again not within limits, the data will be

qualified accordingly. If the recovery is within the limits in the reanalysis,

provide the reanalysis data to the data user.

If the measures listed above fail to correct the problem, the analytical system must be

considered out of control. The problem must be corrected before continuing. Th

may mean recalibrating the instrumentation but it may also mean more extensive

action. The specific corrective action should be defined by the g chromatogmph

(GO) operator with the concurrence of the laboratory supervisor and/or instrument

maintenance specialist. Report the surrogate spike recovery data and the sample

data from both extractions when reanalysis substantiates a matrix effect.5.2 Data CompletenessCompleteness is calculated as the percent of total usable data points out of the set of

total data points collected, analyzed, and available. Data points may not be usable ifsample analysis time exceeded holding times, or if QC sample criteria were not met

hazards associated with samples that contain or may contain radioactive materials.

Depending on the location from which samples are taken and other factors, these.

controls may include:

• Nondestructive analysis to determine uranium content and define required

shipping paperwork

• Special surveys and reporting of radiological parameters for the inner and

outer containers to ensure radiological controls are satisfied and that

packages are properly labeled and marked

• Preparation of official radioactive materials transfer documentation to track

the shipment of materials to the laboratory and identify radioactive contents

Philadelphia, PA 19 103-2029Dear Mr. Friedman:

We are providing three copies of the background, production process and wastewatertreatment system descriptions as well as the groundwater-monitoring plan to support the

development of a delisting petition for the Final Effluent Ponds (FEPs). BWXT hasgenerated the first quarter of groundwater monitoring data for both the FEPs and

Landfill 1 and the second quarter sampling will be performed within the next two

weeks. BWXT has not had the opportunity to review in detail the groundwater

monitoring data for the FEPs.

Please give Jeffrey Howard or me a call at (804) 522-5245 or (804) 522-6677

respectively, if you have any questions.

Sincerely,

kStorton
