                               EXECUTIVE SUMMARY
This report presents results of a radiological survey conducted in September 1999 by the National
Air and Radiation Environmental Laboratory (NAREL) to assess levels of environmental
radioactivity in and around naval harbor facilities located on the Thames River near New
London, Connecticut.  These facilities include the New London Submarine Base (NLSB) at
Groton, the Electric Boat Company (EB) at Groton, Sound Signature Facility and the State Pier.
These facilities will be referred to collectively in this report as the New London Harbor Facilities
(NLHF).  The purpose of the survey was to assess whether the construction, maintenance,
overhaul, refueling or operation of nuclear-powered warships have created elevated levels of
radioactivity in the marine environment which could expose nearby populations or contaminate
the environment.

During this survey 265 samples were collected: 11 were from background locations and 19 near
the outfalls of the public water treatment plants. Samples included drinking water, harbor
surface water, sediment, sediment cores, and biota. All samples were analyzed for gross alpha
and beta activities and gamma emitting radionuclides.  Water samples were also analyzed for
tritium.  In addition to sample collection and analysis, radiation surveys were performed using
portable survey instruments to detect gamma radiation.

The measured cobalt-60 is consistent with and appears to be attributable to the cobalt-60
previously measured at the NLHF, corrected for radioactive decay. While the possibility of a
recent release being masked by the previously released cobalt-60 cannot be completely disproved
by the sample results, such a recent release would likely have little or no adverse impact on
human health or the environment.  Iodine-131 was detected in 11 biota samples and a surface
water sample at a sewer outfall.  The source of the 1-131 is most likely due to medical use.
Radioactivity levels detected in other samples were consistent with levels expected to exist due
to naturally occurring radioactivity or fallout from atmospheric nuclear testing and from the
Chernobyl reactor accident in 1986. Based on this radiological survey, practices regarding
nuclear-powered warship operations at NLHF have resulted hi no increases in radioactivity
causing significant population exposure or contamination of the environment.

1.0 INTRODUCTION

The National Air and Radiation Environmental Laboratory (NAREL) of the U.S. Environmental
Protection Agency (EPA) in cooperation with the U.S. Naval Sea Systems Command (NAVSEA)
has previously surveyed facilities serving nuclear-powered warships. These surveys began in
1963 and have been conducted on the Atlantic and Pacific coasts, on the Gulf of Mexico within
the Continental United States, and at Pearl Harbor, Hawaii. In 1996, an interagency agreement
(LAG) was signed with NAVSEA for NAREL to perform radiological surveys over five years at
active facilities serving nuclear-powered warships.  These surveys assess whether the
construction, maintenance, overhaul, refueling or operations of nuclear-powered warships have
created elevated levels of radioactivity that could expose nearby populations or contaminate the
environment.

The first six environmental surveys under the interagency agreement have been performed as
follows: Puget Sound Naval Shipyard (PSNS) at Bremerton, WA, and the Naval Submarine Base
(NSBB) near Bangor, WA, during 1996 (Fo98); San Diego Bay, CA, (Go99) and Portsmouth
Naval Shipyard at Kittery, ME, (SmOl) during 1997; at the Pearl Harbor Naval Complex
(PHNC), HI, during 1998 (PoOl); the Navy Nuclear Power Training Unit (NPTU), North
Charleston, SC, during 1999 (Fo03); and Kings Bay Submarine Base, GA, in 1999 (EPA04).
The seventh environmental survey under the IAG was performed September 13-24, 1999, at the
New London Harbor Facilities (NLHF), Groton, CT. A pre-survey trip was made July 19-21,
1999, to develop a sampling and survey work plan with the assistance of knowledgeable site
personnel and EPA radiation program representatives from EPA-NAREL and EPA Region 1.
Staff from NAVSEA, New London Submarine Base (NLSB) and Electric Boat Company (EB)
provided NAREL with information on past and present NLHF radiological operations and
procedures. All requested information was freely provided verbally and/or in writing. Based on
the information received and that derived from previous EPA studies, a work plan (EPA99) was
developed to describe the approach for assessing the radiological condition of the NLHF and
nearby aquatic environments.

1.1 Site Description and History (Se91)(Do99)

The Electric Boat Company, New London Submarine Base, State Pier and Sound Signature
Facility are located on the Thames River in New London County in Southeastern Connecticut.
The Thames River is a tidal estuary arising at the confluence of the Yantic and Shetucket Rivers,
approximately 24 km (15 miles) north of the Groton-New London Harbor area.  The river varies
in width from 0.21  km (0.13 miles) to a maximum of 1.82 km (1.13 miles) where it empties into
Long Island Sound. The mean tidal range of the river at New London is 76 cm (2.5 feet).

The New London Submarine Base is located within the City of Groton and Town of Ledyard.
The base is situated on the east bank of the Thames River approximately six miles north of Long
Island Sound.  The main base is bounded by Connecticut route 12 on the east, to the south by
Crystal Lake Road, and to the west by the Thames River.  The northern border is a low ridge that
trends approximately east-southeast from the river to Baldwin Hill. The submarine base
encompasses 1,412 acres of land.

                                         1

-------
Electric Boat Company is located within the confines of the City of Groton. EB is situated on the
east bank of the Thames River approximately three miles north of Long Island Sound. EB is
primarily engaged in the construction of nuclear submarines for the United States Navy.

State Pier is a facility in New London, just south of the Gold Star Bridge that spans the Thames
River.  A submarine tender was stationed at this location from the early 1960's through the
1980's. Nuclear submarines tied up to the tender for short durations during these years. This
facility is no longer used by the Navy.

The Sound Signature Facility is located in New London and was formerly called the Naval
Underwater Warfare Center (NUWC). The piers at this facility were previously used to tie up
Trident submarines after delivery and for short durations. This facility is no longer used by the
Navy.

Groton, EB, and NLSB obtain their drinking water supply from a series of six surface water
reservoirs located northeast and east of the City of Groton (PNS97).

1.2 Survey History

The New London Harbor Facilities were previously surveyed by the Southeastern Radiological
Health Laboratory of the U.S. Public Health Service in 1966 (Ca66), and by EPA in 1972 (Wi73)
and 1989 (Se91).  Detected Co-60  in harbor sediment during the 1966 survey (Ca66) ranged from
10-360 pCi/gm-dry at EB, with an average of 100 pCi/gm-dry; 6-49 pCi/gm-dry at the NLSB;
and 117-200 pCi/gm-dry at State Pier. Higher levels of Co-60 were detected alongside the
Graving Dock and the piers at EB and at piers 10, 12, 13 and 14 at NLSB. Detected Co-60 in
harbor sediment during the 1972 survey  (Wi73) ranged from 0.2-26 pCi/gm-dry.  Cobalt-60
concentrations in sediment samples collected during the 1972 survey from locations that
duplicated those of the 1966 survey had  decreased by a factor of about 30. Average Co-60
concentrations detected in harbor sediment during the 1989 survey (Se91) ranged from 0.14
pCi/gm-dry at the NLSB to 0.26 pCi/gm-dry at State  Pier.  The highest Co-60  sediment
concentrations were 0.65 pCi/gm-dry at EB, 0.23 pCi/gm-dry at NLSB and 0.60 pCi/gm-dry at
State Pier. Sediment samples that duplicated samples obtained in 1972 contained 8-30 times less
Co-60 than the earlier samples.

Cobalt-60 concentrations in 1989 (Se91) core samples ranged from 0.05-0.19 pCi/gm-dry at EB
and 0.14-0.37 pCi/gm-dry at NLSB.  Cobalt-60 concentrations in core samples from NLSB were
about twice those measured at EB (0.2 versus 0.1 pCi/gm-dry).

During the 1989 survey, small concentrations of Co-60, less than 0.1 pCi/gm-dry, were detected
in kelp, sea lettuce and  starfish at EB and kelp, sea lettuce and sea cucumber from NLSB.
Cobalt-60 was not detected in any edible biota. Water samples contained no detectable levels of
radioactivity other than those occurring naturally. Measurements of external radiation exposure
along the two  shorelines of the Thames River ranged  from 3 u.R/hr to 12 fiR/hr. Measurements
taken on the NLSB in areas accessible to the public ranged from 6 u^R/hr to  19

-------
1.3 Contaminants of Concern

The results of previous harbor surveys indicate that cobalt-60 is the predominant radionuclide
one would find in environmental media if radioactivity is present as a result of naval nuclear
propulsion plant operations (Ca77, Ca87). Therefore, environmental sampling during this survey
emphasized detection of cobalt-60.  Other radionuclides of concern in liquid effluents or
encountered during maintenance work would include tungsten-187, chromium-51, iron-59, iron-
55, nickel-63, niobium-95, zirconium-95, manganese-54 and cobalt-58 (ANS99).  Water samples
were also analyzed for tritium since this radionuclide is known to be produced in the coolant of
light-water nuclear reactors.

1.4 Study Objectives

The objectives of the study were to determine if radioactive material related to U.S. Navy
nuclear-powered warship construction, operations, repair, and maintenance is present at
measurable levels in the harbor samples collected, to make comparisons of current study results
with past study results and, as deemed appropriate, to estimate potential doses to the public.

-------
 2.0  SAMPLING, MEASUREMENT AND ANALYSIS

 The following terms will be used in the discussion of the collection of samples and
 measurements:

       Survey Site:                The geographical area in and around NLHF that was
                                  studied.

       Measurement Location:      A location in or near the survey site where gamma radiation
                                  levels were measured.

       Sampling Location:         A location within or near the study site from which samples
                                  were collected.

       Background Location:       A selected sampling location where representative levels of
                                  naturally occurring or existing radionuclides, not likely to
                                  be related to NLHF, were measured.

 2.1 Sampling and Measurement Strategy

 This study was intended to determine the concentrations of cobalt-60 and other selected
 radionuclides that could be present due to the operations performed at NLHF and other selected
 radionuclides that may be present at or near the study site but originated from off-site locations.
 The sampling locations selected were those where the Navy and Electric Boat Company
 presently conduct environmental monitoring, locations where the USEPA-NAREL sampled in
 1989, and locations selected by NAREL to more comprehensively characterize the study site.

 Background sampling locations were selected to obtain baseline radionuclide levels that are
 characteristic of the area. The data from the study site were compared directly to the background
 concentrations when background data were available or to appropriate standards, such as those in
 the national drinking water regulations (FROO).

 Field duplicate samples were either co-located (adjacent) with the original samples or the original
 samples were split. Biota, bottom sediment and water samples were typically composited at the
 sampling location upon collection and then split into duplicate samples.  However, duplicate
 shoreline samples were collected as adjacent samples at the same sampling location.

 2.1.1 Background  Sampling Locations

 Five locations were selected for background sampling. The background locations selected for
 NLHF are on the Thames River north of the Submarine Base (see Table 1 and Figure 9). The
background locations were selected during the pre-survey visit (July 1999) and are located at a
distance far enough away from the survey site so that operations there would not have impacted
those locations.  Therefore, representative levels of existing radionuclides in the samples as a
result of worldwide fallout and natural radioactivity can be measured. The data from the survey

-------
site were compared directly to the background concentrations when applicable.

2.1.2 New London Harbor Facilities (NLHF) Survey Site

The NLHF survey site is on the Thames River at the Electric Boat Company, the New London
Submarine Base and the surrounding environs including the State Pier and Sound Signature
Facility areas. Specific measurement and survey locations are listed in Table 1 and shown in
Figures 1 through 9. Note: Locations 1 and 101 are not shown on any of the figures.  Sampling
locations presently used by the Navy, Electric Boat Company, and sampling locations added by
NAREL were used during this survey. A description of each  sampling location and the type of
sample collected are presented in Table 1. A total of 265 samples were collected during this
survey.  Of that total, 254 samples were collected within the area defined as the NLHF study site.
Eleven of the samples were collected from background locations and 19 samples were collected
near the outfalls of the public water treatment plants for the City of New London, City of Groton,
Town of Groton and Town of Montville. Repeated efforts to  obtain sediment samples at
locations 3 (off Avery Point), 58 (33 yards south of end of "C" Dock), and 141 (halfway between
locations 8 and 9) were unsuccessful.

2.1.3 Instrumentation

At selected locations, primarily public access areas, radiation surveys were performed using
portable survey instruments to detect gamma radiation.  Three types of gamma measuring
instruments were used: a Ludlum Model 19 Micro-R radiation survey instrument, a GENITRON
GM survey instrument and a Reuter-Stokes pressurized ionization chamber (PIC). Instrument
serial numbers and calibration dates are available on the field data sheets. External radiation
measurement locations are given in Table 2 and Figures 1-9.

2.1.4 Table Notes

2.1.4.1 General

Samples were taken as close to piers as situations permitted when a distance was not specified.
Sometimes barges, ships and other equipment prevented collecting a sample close to the pier,
therefore, an alternate location was selected. For each sample and measurement location, the
approximate geographical position (latitude and longitude) of the location was determined in the
field using commercially obtained global positioning system (GPS) receivers. These units had
typical accuracy ranging from 30 to 100 meters. These readings were supplemented by
measuring line-of-sight distances to nearby landmarks.  The distances were measured using a
Bushnell YardagePro 400  laser range finder, which is accurate to within about two meters.

2.1.4.2 Sample Identification

Each sample collected or measurement taken during the survey was marked with a unique code
which denoted:

-------
       •      Location
       •      Matrix or Measurement type
             Sample type detail (e.g. field duplicate, background, sewer outfall)

The sample identification (ID) code has the form NLHFxxx-yyyy-zz, where 'xxx' indicates the
sampling site ID number, 'yyyy' identifies the measurement type or matrix (and species for biota
samples), and 'zz' provides additional descriptive information such as 'DU' if the sample was a
duplicate or 'BG' if the sample was a background location. Not all samples required the use of
all characters. The following table explains the codes used for the different sample types.

Coding for a typical sample might be as follows: an NLHF harbor-bottom sediment sample taken
at location 17 is coded 'NLHF017-S'. If the sample were a duplicate at NLHF location 36, it
would be 'NLHF036-S-DU'.  A duplicate water sample taken at NLHF location 237 (a
background location) is labeled 'NLHF237-W-DU-BG'. A second water sample taken at the
depth of the sewer outfall has an additional identifier of "02" after the location number to
indicate that this is the second water sample collected at this location but at a different depth than
the first water sample, e.g. 'NLHF008-02-W.  "Navy" location ID's have a three letter prefix
with the first two letters indicating the facility (EB for Electric Boat, SP for State Pier, NU for
Naval Undersea Warfare Center and SB for New London Submarine Base) and the third letter
indicating the sample type ("S" for sediment sample, "W" for water sample, "B" for biota
samples and "P" for perimeter thermoluminescent dosimeter [TLD] monitoring location).

2.2 Sample Collection and Analysis

2.2.1 Sample Collection

Shoreline (intertidal) sediment, harbor bottom sediment (grab and core), water (harbor surface,
sewage outfall, and drinking waters), and biota were collected. By previous agreement between
NAREL and the Navy, most samples were split for routine independent comparisons by the
Navy.  The samples collected from NLHF are listed in Table 1. Approximately 5 percent of all
samples collected for each sample type were quality control duplicates. The locations where
duplicate samples were taken are noted in Table 1. All samples were analyzed for gross alpha
and beta activities and gamma emitting radionuclides. Water samples were analyzed for tritium.

-------
Surface Water. A total of 33 surface water samples were collected.  This included two duplicate
samples, one of which was taken at a background location. Eight samples were taken near water
treatment facilities. A total of 31 sampling locations were used. Samples were collected by
lowering a Wildco horizontal water sampling bottle (alpha bottle) to a depth of one meter and
then closing the bottle by releasing a "messenger" that activated a tripping mechanism. (Note:
Four of the samples collected at the treatment facilities were collected at the depth of the outfall
pipe.)  This process was repeated until 5 L of water were obtained. About 4 L of water were
poured into a plastic sample container and acidified to a pH of < 2 with nitric acid. The  acidified
water sample was analyzed for gross alpha and beta activities and gamma emitting radionuclides.
One fourth liter of the water sample was poured into a glass container and, without being
acidified, was analyzed for tritium.

Drinking Water.  Five drinking water samples were collected from 3 taps representing the water
supplies of Electric Boat Company, New London Submarine Base, and a background drinking
water sample collected at a motel in Mystic, CT. The 5 L drinking water samples were divided
into two sample containers and preserved and analyzed in the same manner as were the surface
water samples.

Harbor Bottom Sediment.  During this study, there were 157 locations at which a total of 166
harbor sediment samples were obtained  Of these 166 samples, 8 were duplicate samples, 4 were
collected at public water treatment outfalls, and 4 were at background locations including 1
background duplicate. Sediment sampling from boats was performed using a Peterson dredge to
sample approximately the top 10 cm of sediment. Each sample consisted of approximately 4
liters.

Shoreline Sediment. A total of 8 shoreline samples were collected, of which 1 was a background
sample and 1 was a duplicate sample.  Samples were collected with a small trowel or scoop and
consisted of approximately 4 liters of surface soil collected from the intertidal shoreline near the
low tide line. Stones and organic debris were excluded as much as possible. Any remaining
debris was removed by sieving with a 16-mesh sieve during sample preparation at the laboratory.
 Sediment Core. Thirty-one sediment core samples were taken at 29 sites. This included 2
 duplicates, one of which was taken at a background location. Each core consisted of a 5 cm
 diameter cylinder of sediment up to 51 cm in length. Sediment core samples were obtained to
 evaluate the vertical distribution of radioactivity in harbor bottom sediment. Samples were
 collected by divers who pushed plastic tubes into the sediment as far as possible and then capped
 the ends. Excess water was decanted from the top of each core. The cores were frozen prior to
 shipping and remained frozen during shipping.  Before analysis, the frozen cores were cut into a
 maximum of 5 segments per core with each segment having a minimum length of 5 cm.

 Biota.  Twenty two biota samples were collected at 17 different locations.  These samples
 consisted of 1 duplicate and 1 background sample and contained approximately 4 liters of one

                                           8

species of marine life. Samples were collected from as small a region as possible. Marsh grass
was collected on the shoreline by the EPA sampling team while mussels, sea hair, barnacles,
brown kelp, and starfish were collected by divers.  Because of the interest in iodine-131, all biota
samples were counted wet by gamma spectroscopy within 7 days after collection.

2.2.2 Sample Analysis

Samples for each location were analyzed for gamma emitting radionuclides and for gross
alpha/beta activities.  Of particular interest was cobalt-60 in the sediment samples and iodine-131
in the water and biota samples. All water samples were analyzed for tritium. Specific isotopic
analyses were performed on selected samples.

Gamma Spectrometry. This procedure allows for characterization of the gamma-emitting
radionuclides present in the sample without separating them from the sample matrix.  The limit
of detectability of this method is a function of the sample size, counting geometry, detector
efficiency, background, counting time, gamma photon energy of the nuclide and branching ratio
(percent abundance).  Liquid samples are acidified and soil or sediment samples are ground and
sieved to ensure the homogeneity  of the samples. Biota samples are homogenized prior to
analysis to ensure uniformity of the sample.

Gross Alpha/Beta.  This procedure, which provides a rapid screening measurement, was used
as a gross approximation of the alpha and beta activity present in the sample. Low energy and
volatile radionuclides such as tritium, carbon-14, and iodine will not be detected by this method.
In addition, polonium and cesium may be lost if the procedure requires flaming of the sample.
For water samples,  a known amount of the sample is evaporated to a small volume then
transferred to a small container and further evaporated for measurement. For solid samples, a
known amount of the  sample is placed on the planchet. Water is added and the sample is dried to
provide even distribution. The sample is weighed and counted on a gas proportional counter.
These analyses are not nuclide specific and are not as accurate as other types of analyses.

Tritium Analysis. Water samples are distilled and are incorporated into a counting mixture
consisting of a primary solvent, emulsifier, and fluors. The tritium is assayed in a liquid
scintillation spectrometer.

3.0 RESULTS AND DISCUSSION

The radioanalytical results for the NLHF samples collected during this survey are reported in the
Appendix.  The tables were generated from Data Quality Packages (DQPs) produced from
radioanalytical results. The quality assurance/quality control (QA/QC) results for the laboratory
analyses and field sample QA/QC were presented in the DQPs for the sample analyses, and the
results were within acceptable limits as specified in the Quality Assurance Project Plan (EPA97)
for this survey.  Some of the reported radionuclide activity results are negative. Negative results
occur when a previously determined background value is subtracted from a sample value that is
less than the background value. Negative values represent a portion of the statistical distribution
of negative and positive values around zero for samples containing very little or no detectable
radioactivity.

3.1 Water Samples

3.1.1 Surface Water Samples

The gamma analysis results for the 33 surface water samples are shown in Table A.L Only
naturally occurring radionuclides were detected in surface water samples collected from withm
the area defined as the NLHF. Iodine-131 atalevelof 6.1 ±3.5 pCi/L wasdete ctedatthe
discharge pipe location at the Montville Station Public Owned Treatment Works (POTW)  ewer
outfall  The most likely source of this 1-131 is from medical use in the load population with
resultant discharge of excreta into the sewage. Iodine-131 is used ,n clinical medicine for the
treatment of hyperthytoidism and thyroid cancer. Excreta from ^dividual* undergoing medical
diagnosis or therapy with radioactive material is exempt from the U.S. Nuclear Regulatory
Commission (NRC) regulations for the discharge of radioactive materials iinto municipal sewage
systems in accordance with the Code of Federal Regulations, Title 10, Part 20.2003(b).
Tritium analyses were performed on all 33 surface water ^^^^J1
A.2. Tritium concentrations in the surface water samples collected at NLHF were
those collected at the background location (NLHF237). All of these concentrations were below
the minimum detectable concentration (MDC) of about 140 pCi/L.

Results of the gross alpha and beta analyses of the 33 surface water samples are presented in
Table A 3 Using the K-40 gamma spectrometry data, the surface water background is not
represenfativeTf the sampling  locations.  Beta readings are consistent with expectations based on
the K-40 data.
3.1.2 Drinking Water Samples
The gamma analysis results for the five drinking water samples are shown in Table A.4. Only
naturally occurring radionuclides were detected in drinking water samples.
                                          31

-------
Tritium analyses were performed on all five drinking water samples.  Results are presented in
Table A. 5.  Tritium concentrations in the drinking water samples collected at NLHF were similar
to those collected at the background location (NLHF 101). All of these concentrations were
below the minimum detectable concentration (MDC) of about 140 pCi/L.

Results of the gross alpha and beta analyses of the five drinking water samples are presented in
Table A.6.  The drinking water samples had maximum gross alpha and beta concentrations,
respectively, of 0.50 ± 0.41 pCi/L and 2.4 ± 2.6 pCi/L.  The National Drinking Water
Regulations (FROO) state that the maximum allowed gross alpha particle radioactivity in
community water systems is 15 pCi/L (including radium-226, but excluding radon and uranium).
Gross alpha concentrations in the NLHF drinking water samples were below the maximum
allowed gross alpha activity in drinking water for community water systems. Therefore, the
NLHF samples meet the drinking water regulation.

3.2 Sediment and Sediment Core Samples

3.2.1 Harbor and Shoreline Sediment Samples

The gamma analysis results for harbor and shoreline sediment samples are shown in Tables A.7
and A.8. All samples were counted on a germanium detector for 1000 minutes.  Cobalt-60 was
detected in some sediment samples. The highest cobalt-60 concentrations were 1.820 pCi/g-dry
at EB, 0.074 pCi/g-dry at State Pier, and 0.062 pCi/g-dry at NLSB. The cobalt-60 MDCs for
sediment samples were in the range of 0.013 to 0.029 pCi/g-dry due to the detector used and the
sample size. The presence of cobalt-60 was expected based upon previous surveys conducted by
NAREL at this harbor.

To verify that the cobalt-60 measured in this survey is from previous operations and not newly
deposited cobalt-60, the Thames River and New London harbor were divided into eight sections
 since cobalt-60 contamination varied widely in various sections of the river. For each of the
 eight sections, a half-life for cobalt-60 was calculated using the average concentrations from the
results of the 1972,1989, and 1999 surveys. The half-lives of cobalt-60 in each section ranged
 from 4.1 to 6.6 years.  An uncertainty analysis of the half-lives for each section shows
 satisfactory overlap with the expected cobalt-60 half-life of 5.27 years. Thus, it appears that the
 cobalt-60 concentrations are lowering at the expected rate, suggesting that the cobalt-60 is
 present from previous releases and that no new measurable releases of cobalt-60 have occurred.

 Cobalt-56 was detected in one sediment sample. This was not expected.  Upon further review of
 the gamma radiation spectrum for this sample (NLHF048-S), there is some question concerning
 whether cobalt-56 was actually present, or whether interference from naturally occurring Bi-21*
 in the 1238 keV gamma peak caused the computer softwear algorithm to erroneously indicate the
 presence of cobalt-56. Coupled with the fact that cobalt-56 is not a nuclide expected to be
 detected from nuclear reactor operations (ANS99), the presence of cobalt-56 is concluded to be
 unlikely m that sample. Further supporting this conclusion, cobalt-58 would have been expected
                                           32

-------
 to be detected before cobalt-56 (ANS99); however, no cobalt-58 was detected.

 Results of the gross alpha and beta analyses of harbor and shoreline sediment samples are
 presented in Table A.9.  The maximum total gross alpha and beta concentrations, respectively,
 were 19.9 ± 5.5 pCi/g-dry and 39.2 ± 5.0 pCi/g-dry in samples collected from NLHF; 12.1 ± 4.3
 pCi/g-dry and 29.3 ± 4.3 pCi/g-dry in samples collected at the public water treatment outfall;
 and 9.2 ± 4.0 pCi/g-dry and 24.3 ± 4.1 pCi/g-dry in samples from background locations.
 Sediment samples from NLHF have gross alpha and beta concentrations similar to the
 background and public water treatment outfall samples.

 3.2.2 Sediment Core Samples

 Gamma analysis results for the sediment core samples are shown in Tables A. 10 and A. 11.  The
 maximum cobalt-60 concentration measured in a core sediment sample was 0.534 pCi/g-dry.
 The cobalt-60 MDCs were in the range of 0.025 to 0.106 pCi/g.  The presence of Co-60 was
 discussed above  The samples contained naturally occurring radioactivity and radioactivity
 consistent with levels expected from fallout due  to atmospheric nuclear tests and the Chernobyl
 reactor accident.

 Results of the gross alpha and beta analyses of sediment core samples are shown in Table A. 12.
 Gross alpha and beta concentrations in sediment core samples at NLHF are similar to
 concentrations found in sediment core samples at the background location.

 3.3 Biota Samples

 Gamma analysis results for the 22 biota samples are shown in Tables A. 13 and A.M. Cobalt-60
 readings were below the MDC. Iodine-131 was detected in 11 biota samples.  The source of this
 1-131 is most likely from medical use in the surrounding population.  Other radionuchdes
 detected in biota are naturally occurring or radioactivity consistent with levels expected from
 fallout due to atmospheric nuclear tests and the Chernobyl reactor accident.

 Results of the gross alpha and beta analyses of biota samples are presented in Table A. 15.
 Samples collected from NLHF have concentrations similar to those found in the background
 samples. The gross beta readings for brown kelp at the site locations ranged from 5.77 to  10.17
 pCi/g-wet and the only sea hair sample registered 11.76 pCi/g-Wet. These compare with a
 reading of 2.76 pCi/g-wet for a background marsh grass sample.

 3.4 External Gamma Radiation Measurements

 External gamma radiation measurements were made along the shoreline and on the water at
NLHF with emphasis on areas accessible to the public. M™—*™**™^™1?

readings were also taken for 5 to 10 minutes at each location with a Reuter-Stokes pressurized
ion chamber (PIC). A Ludlum Model-19 was also used to measure variation in exposure rates
along the shoreline at each location. Results of the external gamma radiation measurements are
shown in Table 2. Radiation levels measured were similar to background.

 4.0  QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)

 4.1  The Quality Assurance Program

 The NAREL Quality Assurance (QA) Plan applies to all work performed at NAREL. The
 purpose of the quality assurance program is to ensure that all measurements performed at
 NAREL are valid, scientifically defensible,  and of known precision and accuracy. The NAREL
 Quality Assurance Project Plan (QAPP) for the U.S. Navy Environmental Studies (EPA 97) was
 prepared in accordance with the requirements described in "EPA Requirements for Quality
 Assurance Project Plans for Environmental  Data Operations" (EPA94).

 Quality Assurance/Quality Control (QA/QC) for the laboratory analyses performed for this
 survey is detailed in the QAPP (EPA97).  Quality control (QC) samples are analyzed in
 conjunction with routine samples to ensure the quality of the analytical results.  Corrective
 actions must be taken when it is shown by the results of QC samples that the radioanalytical
 procedure is beyond predetermined control limits. Quality assurance is equally important in the
 sample collection process. All documentation including chain-of-custody forms were properly
 completed. Sampling equipment was in good working order and field  measurement equipment
 was calibrated and properly maintained.

 4.2  Quality Control Samples

 Field and laboratory quality control samples were included with site samples to help evaluate the
 entire sampling and analysis process. Evaluation of QC samples allows assessment of the
 accuracy and precision of the  analytical procedures. The field duplicate results assess the
 consistency of the sampling process and the  representativeness of the samples collected.

 In the laboratory samples were grouped in batches for quality control purposes, with a maximum
 of 20 samples per matrix per analysis type. For each batch, the laboratory analyzed a reagent
 blank, a matrix spike, a matrix spike duplicate, and a laboratory replicate sample. However, for
 gamma spectrometry and gross alpha and beta analyses, only a recount  (duplicate) or split was
 performed for batch QC. Results of these QC samples were reviewed with sample results as part
 of the data verification and review process. Specific criteria for acceptance were included m the
 QAPP (EPA97)  All blank results were maintained on control charts by analyst, matrix, and
 analyte. Warning and rejection limits were used to assess acceptance of the blank results. No
 substantial corrective actions were required during the processing and analysis of the samples for
 this survey  Radioanalytical sample results complied with the terms and conditions of the QAPP
as certified by the NAREL Quality Assurance Coordinator and the Chief, Monitoring and
Analytical Services Branch.
                                         39

-------
4.3 Performance Evaluation Programs

It is NAREL policy to participate in many inter laboratory comparisons of radioactivity
measurements and cross-check programs. NAREL participates in intercomparison QA studies
with the National Institute of Standards and Technology (NIST) in Gaithersburg, MD; the World
Health Organization (WHO) in Le Vesinet, France; the International Atomic Energy Agency
(IAEA), Vienna, Austria; the U.S. Department of Energy (DOE) Radiological Environmental
Science Laboratory in Idaho Falls, ID; the DOE Environmental Measurements Laboratory (EML)
in New York, NY and Analytics, a commercial company in Atlanta, Georgia.
                                         40

5.0 CONCLUSIONS

The following conclusions apply to conditions as found during the radiological survey conducted
September 13-24, 1999, at the New London Harbor Facilities:

1. Trace quantities of cobalt-60 were found in the Sediment. When compared to previous survey
  findings, cobalt-60 concentrations had decreased at an expected rate. It is possible that cobalt-
  60 is present from previous operations and not newly deposited.

2. Cobalt-60 was not detected in biota or water samples.

3 Iodine-131 was detected in a water sample at the Montville Station POTW sewer outfall and in
  eleven biotaTsamples. The source of this iodine is most likely due to excreta from individuals
  in the general population undergoing medical diagnostic or therapeutic procedures.

4 Other radionuclides identified in the media collected in this survey are typically found in the

 General Information for NAREL Analytical Methods

 as Reported in the NAREL Data Quality Packages


 Gamma Spectrometry

 Gamma analysis was done on all collected samples. The activity and 2-sigma uncertainty for
 radionuclides measured by gamma spectroscopy are reported only if the nuclide is detected.
 Nuclides that are not detected do not appear in the report, with the exception of barium-140,
 cobalt-60, cesium-137, iodine-131, potassium-40, radium-226, and radium-228. If one of these
 seven nuclides is undetected, NAREL reports it as "Not Detected" or "ND".

 Due to potential spectral interferences and other possible problems associated with the
 determination of the activity for certain radionuclides, the activities for thorium-234,
 protactinium-234m, radium-226, and uranium-235 are subject to greater possible error than other
 commonly reported radionuclides.  Note that this potential error is not included in the 2-sigma
 counting error reported with each activity.  Although in this report we do provide the calculated
 activities for these radionuclides, we recommend that the results be used only as a qualitative
 means of indicating the presence of these radionuclides and not as a quantitative measure of their
 concentration  The results for these nuclides are not used in the evaluation of quality control
 samples  Furthermore, because of mutual interference between radium-226 and uranmm-235,
 NAREL's gamma analysis software tends to overestimate the amounts of these nuclides
 whenever both  are present in a sample. Lower estimates for radium-226 activities can be
 obtained from the reported activities of its decay products, lead-214 and bismuth-214, which
 could be somewhat less than the radium-226 activity because of the potential  escape of radon
 gas.
NAREL's gamma spectroscopy software corrects activities and MDCs for decay between
collection and analysis, but only up to a limit often half-lives.  So, if the decay time for a sample
is more than ten half-lives of a radionuclide, that nuclide will almost for certain be undetected,
and the reported MDC will be meaningless. This is usually a problem only for short-lived
radionuclides, such as iodine-131 and barium-140, when there is a long delay between collection
and analysis.

Gross Alpha and Beta Analysis

In comparison to the methods employed to determine radionuclide-specific activities, the method
employed by NAREL to determine gross alpha and beta activity has the potential for greater
analytical bias  This is especially true for soils. Note that this potential analytical error is not
included in the 2-sigma counting error term. Therefore, gross alpha and beta results should be
used as gross approximations of the alpha and  beta activity present.
