                              EXECUTIVE SUMMARY
             -EPAJearnedo£analarming^tatistieconcerning4heShoaLwaterJBay IndianJTribe^jf
 Western Washington: Over 90 per cent of Tribal pregnancies between 1990 and 1992 had ended
 in miscarriage, stillbirth, or infant death within the first year of life. In addition, a high number of
 other reproductive problems and birth defects were reported by the Tribe.

 Although human health studies were being conducted by the Washington State Department of
 Health and the Indian Health Service, insufficient information existed to determine whether an
 environmental component to infant survival might exist.  Additionally, Tribal members were
 concerned that their natural home, located along the shores of Willapa Bay in Southwestern
 Washington, was not safe. Tribal elders spoke offish and shellfish that no longer inhabited their
 shores and of concerns about what might be hidden in the  soils of a nearby dump. The Tribe felt
 their lives were integrally tied to the environment, and if the water, the wildlife and the fish were
 being threatened, so might their existence. As Herb Whitish, Chairman and tireless spokesman for
 the Tribe, said, "The Shoalwaters could be the proverbial canary in the mine for the entire Willapa
 Bay."

 After meeting with the Tribe about their concerns, as well as with members of other federal,
 county and state agencies, EPA began a limited environmental assessment—to take a snapshot—of
 the quality of household drinking water, fresh and marine surface water, and various sediment
 routes which constitute important environmental exposure pathways for the Tribe and
 surrounding environs. Although EPA did not expect to find a direct link between environmental
 conditions and infant mortality, it was determined that there were many questions that scientists,
 environmentalists, business people, and Tribal members could not answer without this
 information.

 In consultation, with the Tribe and others, four specific pathways of potential environmental
 exposure were chosen for analysis: (1) drainage from a nearby abandoned dump; (2)  agricultural
 runoff from cranberry farms, forestry and other sources; (3) tideflat sediments on or near Tribal
 lands, and (4) drinking water at Tribal household taps.

 Between June, 1994 and March, 1996, EPA scientists and field staff gathered information,
 conducted on-site investigations, and analyzed samples at the EPA laboratory at Manchester,
 Washington.  The quality of project data was established by strict adherence to all standard EPA
 laboratory protocols and data validation guidelines. In addition, the Tribe had some of the
 samples analyzed independently at a private laboratory.

 Inasmuch as the study was dealing with issues so vital to the Tribe, results and an interpretation of
 their significance were communicated to them in person on  a real time basis. Information was
 also directly communicated to the Shoalwater Health Concerns Advisory Committee for their
 review and integration with Tribal medical records and other health related data. EPA's  Senior
 Toxicologist and project lead for this study serves as EPA representative to this Committee made
up of scientists and medical doctors from eight different organizations throughout the country.
                                           111

-------
 Of the four environmental pathways examined, drainage from cranberry bogs was the most
 troubling.  Several pesticides found in the runoff in this area were at levels that exceed federal and
 state water quality standards. Risks to humans or animals that might wade in the ditch or drink
 surface water during periods of application are considerable, as are risks to "non target" species
 such as fish, aquatic birds, and small invertebrates.

 For  drinking water, low levels of total coliform bacteria were found at about 14 per cent of the
 households tested.  Tests for fecal coliform and for the presence of chlorine led investigators to
 conclude there was insufficient chlorination to treat bacteria in some of the systems.  Examination
 of water from household taps showed slight elevations for some "first-pour"  samples—a typical
 response for older water delivery systems—but no violations of federal lead standards were
 observed.

 Results from the dump site waste stream showed no obvious significant risks to human health or
 the environment.

 Sediment samples from the tideflats were relatively clean. However, two compounds were found
 that  mimic herbicide compounds not typically used in marine environments. One is not currently
 registered for use in the U.S.  While the report concludes that these two compounds are most
 likely natural by-products of the marine environment, however further research to identify and
 characterize these compounds is recommended.

 An important component of this study is the recommendation for further research in areas not
 covered by this limited investigation, and where concerns were identified. For example, two
 exposure pathways—air and ground water—were not examined.  Vulnerable ground water
 resources under areas of pesticide application and runoff should be investigated.  Likewise, air
 monitoring in targeted areas during pesticide and herbicide applications is needed. The report
 suggests further study of the long term ecological impacts of carbaryl and glyphosate applications,
 used to eradicate "ghost shrimp" and Spartina cord grass, respectively.

 The  report also recommends improved management practices, public education and technical
 assistance in such areas as drinking water, septic system operations and pest management.

 As expected, this study did not uncover a direct link between infant mortality and environmental
 conditions. It did however, provide the Tribe reasonable assurance that the areas examined on
 and near the reservation were relatively clean and that others, like drinking  water, could be
 improved by fairly simple procedures, such as chlorination and the flushing of tap water. Tribal
 concerns about the effects of pesticides and herbicides on the Willapa Bay ecosystem are given
 credence by the findings of the report. At this time, long term effects are unknown and further
 study is clearly needed.

 This  study represents science in its most human form—empathy for the fears of an under-
represented, small group of people, concern about the effects of man's treatment of the landscape,
and commitment to sound scientific methods.  It reflects many hours of discussion with Tribal
members and their staff, as well as consultation with scientists and environmental program
specialists outside EPA Region  10.

Although the Shoalwater Tribe is the primary client for this work, it provided valuable experience
for the Agency in terms of strengthening its cross-program focus and effectively utilizing in-house
scientific talent. It may very well set a template for the Region and the Agency to more
effectively and credibly address future complex multidisciplinary and ecosystem-driven health
issues which lie "outside the box" of traditional EPA business.

                                      ABSTRACT
^The Shoalwater BayJndian-Reservation-is located-orLWillapaJBay^an^ecologicalLyJiyer&ehut	
 rapidly developing, multi-use Pacific Coast estuary. The Tribe has recently experienced various
 reproductive problems, typified by an unusually high infant mortality rate.  As part of an ongoing
 evaluation conducted by various health agencies and experts, EPA Region 10 performed a
 screening assessment of four nearby environmental exposure pathways important to the Tribe.
 These included: (1) An abandoned dump drainage to a tidal slough, (2) various tideflat sites in the
 vicinity of the Reservation subject to occasional direct applications of pesticides under special
 permits, (3) drainage from nearby cranberry bogs receiving intensive pesticide application, and (4)
 drinking water at 42 stations including two wells and taps at 40 buildings.

 Drinking water excepted, only a small number of environmental samples were taken. However,
 each sample was tested extensively for likely /relevant chemical and/or microbiological
 contamination.  This study was intended to be a one-time sampling "snapshot", and was not
 designed to specifically examine other vital exposure pathways such as air and ground water.

 Results revealed no specific environmental contamination to  suggest a causal or contributory
 relationship to the Tribe's ongoing health and reproductive problems.  At the dump site drainage,
 findings were not indicative of a contamination problem. However, the study did reveal some
 ongoing contaminant problems and issues in the Willapa Bay ecosystem which need to be
 addressed.

 The most obvious environmental problem was pesticide contamination of surface water in runoff
 from cranberry bogs, where DDT, azinphos-methyl, chlorpyrifos, and diazinon were detected at
 excessive levels, some of which exceeded Federal and/or state water quality standards.

 Intensive chemical residue analysis of tideflat sediments appeared unremarkable, except for the
 unexpected but pervasive findings—usually at levels of hundreds of ug/kg~of two "novel" bromo
 and iodo  compounds: 4-hydroxy-3,5-dibromobenzoic acid, and its iodo analog.  Mass spectral
 properties of the two compounds  respectively resemble those of the two synthetic herbicides,
 bromoxynil and ioxynil, neither of which is known to be applied in the Willapa Bay area. Because
 of their ubiquitous presence at remarkably consistent levels— from greatly divergent tideflat areas
 and at different timeframes (February and August)~they appear to be natural products, rather
 than deliberately introduced xenobiotics.

 In all but  one case, tideflat shellfish and overlying seawater collected from representative Willapa
 Bay and Tribal areas did not violate current standards for levels of enteric bacteria. However,
 surface water sampled near the Tribal "swimming hole" showed recent fecal contamination,
 possibly indicating a faulty septic system.

 Drinking water lead concentrations at all household taps  tested were all below EPA's lead action
 level of 0.015 mg/1, but a significant number were positive for total coliforms, indicating the need
 for better chlorination of delivery systems, both on and off-Reservation.
                                            VI

-------
In screening for possible ecotoxicological effects in area shellfish, histopathological assays
revealed no evidence of gonadal neoplasia among 51 samples of the softshell clam Mya arenaria
obtained from the Tribal "swimming hole", and from the North River /Smith Creek inlet to
Willapa Bay.	

Several recommendations are made for further environmental research, technical investigations,
and modifications in resource management practices.  These specifically include screening for
possible contaminants in local ground water and air, determining the identity and sources of the
two novel halogenated tideflat compounds, improvement of drinking water delivery and sanitation
containment systems, and developing better pesticide regulatory and management solutions for
the area. Further studies are also recommended to address possible health and environmental
risks of carbaryl and glyphosate, which are directly applied to local tideflat areas to respectively
control "ghost shrimp", and invasive populations of Spartina cord grass.

  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
                           Chapter 1.0  BACKGROUND
 1.1  The Shoalwater Indians

 The Shoalwater Bay Indian Tribe (SB IT) is a small group of Native Americans (about 155
 members), many of whom live on or near their  1033 acres of Tribal trust land located in Pacific
 County, Washington, on the shores of Willapa Bay (1) (Figure 1). Based on the decennial census,
 131 persons resided on the reservation in 1990.  Rural and remote Pacific County, one of the
 poorest in the State, is also the home of about 500 other American Indian tribal members, with
 various other affiliations which include the Quinault, Quileute, Hoh, Chehalis, Makah, and other
 Pacific Northwest tribes.  The Shoalwaters have historically sought to interact closely with their
 coastal ocean environment, and derive much of their subsistence and livelihood from activities
 which embrace and enhance natural resource utilization in the dynamic and productive Willapa
 Bay ecosystem.
 1.2  Major Problems with Reproductive Health Outcomes:  High Infant Mortality:
 Epidemiologic Studies Culminating with the "Joint Report" of the Shoalwater Bay
 Emergency

 On July 7,  1992, news first emerged of an unusually high infant mortality rate among the SB IT
 (1),(2),(3). On that date, the Shoalwater Bay Tribal Council (SBTC) declared a health emergency
 on the reservation, due to a "high pre-natal and neonatal infant mortality rate, which may exceed
 90 percent (%) for the last two years".

 Following this announcement, a joint epidemiologic examination of adverse reproductive
 outcomes on the Reservation from 1982-1992 was initiated by the Portland Area Indian Health
 Service (IHS) and the State of Washington Department of Health (DOH) (2).

 The preliminary draft report of this effort was then presented to the SBTC in October, 1993. By
 this time, the problem had expanded in scope as the research revealed various other chronic health
 problems among the Tribal population.

 The controversial nature of such a topic met with strong perceptions and reactions among
 members of the Tribal community. This resulted in the Tribal Council recommending that the
 draft study be subjected to independent, outside scientific review. The Tribe asked three specific
 reproductive health scientists and the Centers for Disease Control and Prevention (CDC) to
 review the draft and suggest changes.

 Through these efforts, the Washington State DOH and IHS preliminary report (2) was drafted
 into  a more comprehensive and refined "Joint Report" (3), which incorporated changes suggested
 by reviewers, analysis of needs by the Advisory Committee, and perceptions and reactions by
 community members. The Advisory Committee reviewed and approved this Joint Report,

 and it was also reviewed and approved by the SBTC on October 27, 1994.  The final Joint
 Report, summarizing what was known about the Tribe's pregnancy and infant mortality
 emergency situation, was thus a joint effort of the SBTC, the Washington State DOH, and the
 ms.
 1.3 Findings of the Final Joint Report

 The results of this Final Joint Shoalwater Bay Report were released in December of 1994 (3).
 The data corroborated Tribal concerns about high rates of on-reservation adverse reproductive
 health outcomes.  Of nineteen on-reservation pregnancies identified for the Tribe between 1988
 and 1992, only nine infants (47%) survived their first year of life. Statistically, the ten adverse
 outcomes /infant mortalities included three ectopic pregnancies (16%), three miscarriages (16%),
 two stillbirths (11%), and two infants (11%) who died before reaching their first birthdays.

 Although the rates were based on small numbers, the severity of the problem of adverse outcomes
 of the on-reservation pregnancies between 1988 and 1992 can be roughly compared against the
 "expected" rates for Washington State as follows:

        •     The rate of stillbirths was 29  times the "expected" rate.

        •     The infant mortality rate was 24 times the "expected" rate.

        •     The rate of ectopic pregnancy for the Tribe was 10 times the "expected" rate.

        •     The rate of miscarriage was 1.2 times the "expected" rate.


 1.4  Historically Inadequate Access to Health Care

 The general health care situation for Native Americans is bureaucratically complex, highly
 compartmentalized, and often somewhat bleak.  The IHS serves via its Portland office about
 130,000 American Indians in Washington, Idaho, and Oregon, but receives congressional funds to
 support only 60% of tribal medical needs (1). There is thus a chronic limitation of adequate
 health facilities and care, and a corresponding limit on a given tribe's ability to plan and develop
 appropriate prevention programs. The IHS is also  a "payer of last resort", which means that
 most of the time, the Shoalwaters have had to vacillate between state and federal government to
 receive health care. For the SBIT, such bureaucratic fragmentation meant that  some of the health
 data for the Tribe was received by Medicare  and some by MS, leaving neither agency with a clear
 picture of the actual health crisis (1). The Final Joint Report noted that for the  Shoalwaters, there
 was a "difference of access" to "a broad-based... delivery of personal and public medical and
 health care, and... community-based health promotion programs". Access to health care was
 identified as a major problem (even  the major problem) (3).

 Until the completion of their own modern on-site health clinic in 1995 (financed in part via a
 $250,000 annual grant from Congress and a $100,000 grant from the IHS), yet another problem
 for the Shoalwaters had been the necessity to drive northward about eighty five miles each way to
 the Taholah Clinic, which was the IHS-designated clinic for that service area.  Once at Taholah,

 1.5  Formation of the Shoalwater Bay Health Concerns Advisory Committee  (May, 1994)

 Along with the funding efforts and research initiatives outlined above, a special committee of
 medical, epidemiological, health care and environmental professionals was convened in Seattle on
 May 3, 1994.  The function of this committee is to continually review and evaluate data and
 information relative to the Shearwater's health crisis, and to advise and assist the SBIT in
 conducting health assessments, environmental testing, and educational outreach.  The Committee
 meets quarterly, examines current issues and health /environmental data, and makes
 recommendations to Tribal leadership and management, including the five member Shoalwater
 Bay Tribal Health Board.

 Members currently appointed to the Shoalwater Bay Health Concerns Advisory Committee are
 listed in Appendix A.
 1.6 The Shoalwater Bay Tribal Health Board

 To deal with this health emergency, and other health-based issues, the SBIT also relies heavily on
 its own internal Health Board. Members of the Health Board are frequent observers during the
 formal meetings of the Health Concerns Advisory Committee and are kept closely informed of the
 Committee's decisions and recommendations. Members currently appointed to the Shoalwater
 Bay Tribal Health Board are listed in Appendix B.

 2.1  Possible Environmental Risk Factors: A Prelude to EPA's Involvement

 The Joint Report did not reveal the existence or likelihood of any environmental "smoking gun".
 While the number of pregnancies investigated was too small to adequately assess environmental
 exposure, conclusions and recommendations of the Joint Report did, however, raise the possibility
 that environmental factors could play a role in the infant mortality problems experienced by the
 Tribe.

 Many environmental risk factors are known to be associated with adverse pregnancy outcomes,
 including miscarriages. The original epidemiologic study by JJHS and the Washington State DOH
 did not conduct environmental testing, but did ask Tribal respondents about a large number of
 variables potentially associated with environmental exposures.  These included exposures from
 diet, drinking water sources (e.g., the main well which serves the Reservation), frequency of
 consuming locally harvested seafood, occupation (including maternal and paternal job exposures
 in local industries), and other sources such as exposure to pesticides, exposure to toxic substances
 through hobbies, etc. The frequencies of such exposures were similar among women with and
 without adverse outcomes. The original study did not do environmental tests for exposure to
 possible airborne, waterborne, or food borne toxins, or to toxins unknown to the women surveyed
Based on these uncertainties, the Report recommended that in addition to immediate and broad
efforts to improve the quantity and quality of comprehensive health care, delivery of health care,
and community health promotion, that "prudent environmental risk assessments and studies based
on routes of exposure be conducted and collated with health assessments of tribal members".
This EPA report is one element of the environmental risk assessment.
2.2 EPA Undertakes a Preliminary Environmental Study

By December 1994, public and news media attention had focused intently on the plight of the
Tribe (4),(5),(6), further underscoring the need to obtain baseline screening data on possible
environmental contaminants and exposure pathways in the area which might somehow be relevant
to the Shoalwater Bay health crisis.

Since first becoming aware of the problem in 1993,  EPA Region 10 had shared the Tribe's
concerns. To respond to the concern that current environmental contaminants might be adversely
impacting the health of the people of the Shoalwater Bay Indian Tribal Community, EPA
Regional Administrator Chuck Clarke met with Chairman Herbert Mark Whitish at the
Shoalwater Bay Tribal Headquarters on June 2, 1994.  At that meeting, Administrator Clarke
committed to a limited, but highly focused preliminary screening  study to help explore the

 possibility that Tribal exposure to various environmental stressors in the Shoalwater Bay
 ecosystem might somehow be related to these health and reproductive problems.
Revision 3.0, January 17, 1997                                                      Page: 6of 89

              Chapter 3.0   SCOPE AND DESIGN OF EPA STUDY
 The EPA investigation of four possible environmental pathways which might influence infant
 mortality and reproductive success was designed as a preliminary screening study, involving the
 relatively intense and specific investigation of targeted chemical residues in a small number of
 carefully chosen samples, from these exposure pathways.

 Because funding for this screening effort was limited, the EPA study conducted no formal
 exposure modeling. Likewise, the intense investigation of a small number of environmental
 samples precluded a more "statistical" sampling design (involving many sample points, and
 correspondingly greater labor and expense).  Rather than focusing on a large number of samples
 and analyzing in rote fashion for the more easily obtained, common environmental analytes, the
 EPA study went well beyond this approach in the laboratory, choosing instead to concentrate on
 specific and carefully selected analytes in a relatively few carefully chosen environmental samples.
 3.1  Drainage From the Nearby Dump Site

 For several years, the Shoalwater Bay Tribe had been concerned about the possibility of chemical
 exposure to their lands via drainage from an abandoned dump site (see Figure 2).  This dump is
 located just inland from the tideflats across State Route (SR) 105, approximately two miles west-
 north-west of the Tribal Headquarters, and drains seaward via a series of small ravines and
 rivulets which drain this hillside area.  The dump site and associated landfill had apparently not
 been fully characterized in terms of actual use history,  and contents.  The Tribe, which derives
 much of their subsistence on locally obtained fish and shellfish, was concerned about potential
 contamination from this dump significantly impacting the aquatic ecosystem immediately
 downstream.

 For these reasons, it was decided to examine the lower leachate stream from this station for
 chemical contaminants. The Tribe was especially concerned about heavy metal  contamination,
 munitions compounds, and antifouling paints which might have been dumped there.

 The major surface leachate drainage from the dump site proceeds seaward via a small, year-round
 rivulet which runs along the base of the wooded ravine adjoining the dump. Flowing through a
 culvert under SR 105, the rivulet then drains to the upper intertidal area through a brackish
 slough. Drainage may flow directly to the tideflats during high tidal conditions,  or indirectly by
 seepage through a salt marsh during low water conditions.

 3.1.1  Number and Type of Samples Taken

 A total of five samples (Stations #1 - 5, Figure 2) were taken from along the dump site area
 drainage. These included three sediment and two water samples.  One sediment sample was taken
 from an area of leachate discharging from thlTbase offhlTdump, midway up the ravine.  A second
 sediment sample was taken from the stream about 70 feet uphill from SR 105 and after the stream
 traversed the bottom area of the dump.  A third sediment sample was taken from the slough
 across SR 105, which is the terminus of the drainage from the dump site.  Two water samples
 were also obtained.  These were taken at the same stations as the two sediment samples
 previously described from the mid and lower parts of the dump-ravine runoff.  No concomitant
 water samples were taken from the supratidal slough area below the road.

 3.1.2  Sediment Analytes of Concern

 •     Full target compound list (TCL) of organics and pesticides, and the target analyte list
       (TAL) of metals were measured.

 3.2  Agricultural Runoff from Cranberry Bogs, Forestry, and Other Sources

 The second area of EPA's concern about possible environmental contamination of the immediate
 Shoalwater Bay ecosystem focused on the general issue of pesticides from nearby agricultural
 sources. Immediately northrand^wesTof tfie^Shoalwater Bay~Trib~allands are areas of intense
 cranberry culture, as well as various types of forestry and other agricultural endeavors, both
 public and private. Approximately 800 acres are cultivated for growing cranberries in the near
 coastal area between Grays Harbor and Willapa Bay (7). Cranberries are grown in bogs, and
 spend nearly all of their growth cycle in saturated soil.  Many pesticides are applied to these
 cranberry bogs, to control various pests and diseases which hinder crop production. On the
 Northwest Pacific Coast, rain and moist climates assure the transport of these pesticides offsite,
 from the bogs and from the forests adjoining them, via  surface water drainage to Willapa Bay.
 Agricultural chemicals which are used in or near wetland areas are especially difficult to contain
 on site, even under best management practices and ideal situations.  Cranberries in particular are a
 "minor use crop", and consequently there are few commercial pesticides registered and designed
 especially for cranberry farming.  Thus, cranberry growers must frequently seek permission to
 apply new pesticides under special or experimental registration permits issued from the State
 Department of Agriculture, responsible for administering and enforcing the EPA Federal
 Insecticide, Fungicide, and Rodenticide Act (FEFRA), which regulates the registration and use of
 all pesticide products.  Knowing this, and knowing that numerous pesticides are legally applied to
 the bogs during the growing season, samples were collected during the summer peak application
 period.

 For the EPA sampling effort, it was decided to focus on a major drainage stream emerging from a
 very large area of numerous  cranberry bogs, located just between the coastal forest and SR 105,
 about two miles northwest of Tribal Headquarters (Figure 2.).  After leaving the bogs, the stream
 proceeds southward between SR 105 and the ocean, and finally discharges to Willapa Bay at a
 point about a mile northwest of the Tribal Headquarters. For screening purposes, the samples
 were taken under what were perceived as "worst case" conditions; i.e., during the summer period
 of greatest pesticide application, and at stations specifically chosen to reflect areas of high
 pesticide loading as a consequence of upstream agriculture practices. Concomitant samples of
 sediment and water were taken at two points along a common drainage stream exiting a major
 bog area, as it made its mile-long progression to the nearby tidelands.   .

 3.2.1 Numbers and Types  of Samples Taken

 A total of four samples were taken from the area draining this intense agricultural area (Stations
 #6-9, Figure 2). These consisted of two sediment and two water samples from the overlying
 water column. One set of samples was taken just north of SR  105, where the stream exits nearby
 cranberry bog properties.   The second set of samples was obtained about one half mile
 downstream, where the stream becomes tidally influenced, and about one quarter mile onto the
 intertidal shoreline.

 Because these samples targeted the  most likely conditions for agricultural pesticide contamination,
 chemical analyses were directed toward  on a suite of carefully chosen pesticide residues likely to
 be used in such endeavors as  cranberry culture, forestry, and general agriculture.

                     Detection Limits for Water: 10 ug/1
 3.3 Tideflat Sediment in the Vicinity of the Shoalwater Bay Indian Tribal Lands (See
 Figure 3)

 The possibility of chemical pollutants in the tidelands near the Reservation has long been a
 concern of area residents. These concerns are well-founded.  Although the Willapa Bay
 ecosystem is a dynamic and well-flushed estuary, its wealth of natural resources are sought after,
 and managed, by an increasingly greater and complex array of various private and public interests.
 Accordingly, there are numerous known sources of xenobiotic contaminants which conceivably
 can enter areas where subsistence on local fish and shellfish is important to local residents.

 For example, considerable portions of the tidelands adjacent to the Shoalwaters have historically
 been sprayed each year with the pesticide, carbaryl. Applied under a special State permit, carbaryl
 controls the populations of ghost shrimp, of the genera Neotrypaea (formerly Callianassd) and
 Upogebia, which interfere with oyster production because their burrowing activities can bury or
 smother oysters (8). Also, herbicides such as glyphosate are applied in certain areas of the Bay,
 to control invasive stands of the non-native seagrass, Spartina. There is also considerable local
 concern about herbicides and other pesticides entering the Bay from roadside applications around
 its periphery, from forestry operations in the area, and from other agricultural runoff in the region.

 Possible contamination from the Columbia River is another source of concern. The Columbia,
 laden with agricultural and industrial pollutants pours into the Pacific fifty miles down the coast.
 The Tribe contends that the Columbia River Gyre, a vast eddy driven northward along the coast
 in its clockwise Coreolis rotation,  dumps a significant portion of this pollutant load directly into
 their portion of Willapa Bay.

 For these reasons, it was  decided to select a small number of carefully chosen sediment samples
 from the tidelands adjacent to the Tribal lands, and analyze them extensively for possible chemical
 residues. At this preliminary stage, only sediments were sampled and analyzed; no  samples of
 benthic biota were taken.

 3.3.1 Number and Types of Samples  Taken

 A total of five sediment samples were obtained from preselected representative areas of the
 inshore tidelands of Willapa Bay (Stations #10-14, Figure 3). Results of the initial sampling
 prompted the collection of a similar sediment sample from Grays Harbor, a separate,
 hydrogeologically similar estuary to the  north, for purposes of comparison (Station #23, Figure

 3.3.3  Microbiological Screening: Two Intertidal Water Samples

 Recently, there has been a concern that fecal contamination from failing septic drainfield systems
 may be leaking onto the beach in the vicinity of the tribal "swimming hole". EPA evaluated two
 intertidal water samples for fecal coliforms, enterococci, E. coli., and Pseudomonas aentginosa
 concentration.  Samples were obtained during an incoming tide. One sample (Dexter-by-the-Sea;
 see Figure 4) was chosen as the station nearest the actual swimming hole. The second sample
 was located north of the swimming hole and at a station of potential fecal contamination.
 3.4  Drinking Water Stations in the Vicinity of the Shoalwater Bay Indian Reservation

 As part of this EPA preliminary screening study, a drinking water survey of selected on- and off-
 reservation water system taps was conducted in October 1995. The intent of the sampling event
 was twofold. The first goal was to screen drinking water for bacteria, lead, or other inorganic
 contaminants. The second goal was to provide the Tribe additional information useful for
 designing a more comprehensive drinking water investigation. The drinking water sampling event
 supplements earlier work, including a 1993 EPA analysis of synthetic organic compounds in the
 main tribal water-supply well (9),(10),(H).

 Contaminants in drinking water can originate in the water source (such as ground water or surface
 water), in the distribution system between the source and the residence, and in  the residence
 distribution system. Most residences and community buildings were sampled for bacteria and
 lead, because these parameters are more likely to vary as a result of conditions in and around the
 distribution systems.  For example, lead can originate from leaded pipes, solder or packing.
 Bacterial contamination can originate by infiltration from failing septic drainfields or some other
 bacterial source into the distribution pipes.  A fewer number of stations, but still sufficient to
 include most water sources used by tribal members, were sampled for complete inorganics
 (metals, anions, and nutrients). Inorganic parameters other than lead are likely to vary as a result
 of conditions in the different ground water or surface water sources rather than in the distribution
 systems.

 The  study area for the survey encompassed tribal residences and community or business stations
 on the Shoalwater  Bay Indian Reservation and in or near Dexter-By-The-Sea, Ocosta, Westport,
 Grayland, South Bend and Bay Center.  The water sources that serve these  distribution systems
 are listed in Table 1.  In all, 42 stations were sampled for one or more of three suites of
 parameters:  bacteria, lead, or complete inorganics. Of the 42 stations, 36 stations were sampled
 for bacteria, 32 stations for lead, and 19 stations for complete inorganics.

  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994- 1995
         Chapter 4.0  FIELD ACTIVITIES AND METHODOLOGIES
 This field screening study involved: (1) sediment, water, and microbiological samples at an
 abandoned solid waste disposal site; (2) sediment and microbiological samples from a water
 recreation area; (3) a reference sediment sample from South Bay in Grays Harbor; (4) sediment
 and water samples in a drainage ditch from a cranberry growing area; (5) sediment, water, or
 microbiological samples in five shellfish harvesting areas in Willapa Bay; and (6) a drinking water
 survey. Sediment, water, drinking water and tissue samples were collected and analyzed for a
 variety of organic, inorganic, trace metals and microbiological parameters depending on the
 potential threat from the pathway in question.  The location of the sample stations, other than the
 drinking water samples, in and near the Reservation is shown in Figures 1-3. The location of
 drinking water samples is shown in Figures 4-6.

 The abandoned solid waste disposal site is located on the west side of an unnamed stream that
 enters North Cove on the west side of the reservation.  The site is on the side of a low hill and
 starts about 1/4 mile north of SR 105, and extends about 1/4 mile north along the right bank of
 the stream.  Debris from the dump is scattered throughout the flood plain and is also in the active
 flowing stream.

 The water recreation area is located on the Reservation just north of the new tribal center and
 close to a housing area.  It is referred to as a swimming hole, but swimming is only possible at
 high tide.  However, this area is sometimes used for wading by young children during low tide.
 The Reservation hardshell clam bed is located about 1/4 mile to the south of the swimming hole.

 The drainage ditch from the cranberry growing region enters Willapa Bay just west of North
 Cove.  The ditch is nearly 5 miles long and drains cranberry bogs located south of the
 Pacific/Grays Harbor County line.

 The five most commonly used shellfish harvesting areas are:  (1) commercial oyster beds  on the
 south side of the Willapa River Channel and north of Stony Point, (2) the Hawks Point hardshell
 clam beds, (3)  an oyster bed located on the west side of the Cedar River channel, (4) a hardshell
 clam bed on the Reservation, and (5) a razor clam beach at North Cove.

 The drinking water sampling event was conducted primarily at residences on the reservation, but
 also included off-reservation tribal members' residences in nearby communities of Dexter-By-The-
 Sea, Grayland, Westport, Ocosta, and South Bend.  Samples for the drinking water survey were
 also collected from two tribal wells and from the Shoalwater Bay Oyster Company near Bay
 Center.

 4.1  Sample Collection

 The location, media, analysis required, sample type, and the sampling dates for the water  and
 sediment samples are listed in Table 2. Similar information is shown on Tables 3 and 4,
 respectively, for the microbiological and drinking water samples.

Revision 3.0, January 17, 1997
Page: 23 of 89

-------
  The Shoalwater Bay Reservation: A Limited Environmental Assessment,  1994 - 1995
 All samples were transported in insulated coolers containing crushed ice and analyzed at the EPA
 Manchester Laboratory.  These samples were transported, stored, and analyzed according to
 specifications of the Quality Assurance Project Plan (QAPP).

 4.1.1  Sediment

 Surface sediment was collected either with a precleaned stainless steel spoon or, for some of the
 water areas, with a precleaned Ekman dredge (dimensions 6"x6"x9" deep).  The Ekman dredge
 was thoroughly brushed and rinsed with on-site and deionized water between samples.  An
 attempt was made to sample the top six inches of sediment, but at some stations this was not
 possible due to the sediment type (clay, root masses, or soft substrates) or due to visual
 limitations when sampling below water with the Ekman dredge.  When the Ekman dredge was
 used for sampling, sediment was removed from the dredge with a precleaned stainless steel spoon.
 Only sediment not touching either the sides or the bottom of the dredge was collected for
 analysis.

 For the estuarine sediment samples above water, a clear plastic core (10 cm in diameter by 20 to
 25 cm long) was taken adjacent to each sample station to obtain a field description of the
 substrate, i.e., color, stratification, organic material and odor. Sediment from the descriptive
 cores was not sampled for analysis.

 Sampled sediment was initially placed in precleaned 1-gallon jars.  The jars were filled
 approximately two-thirds full and mixed to an even color and consistency with a precleaned
 stainless steel  spoon. Mixed sediment from these containers was then placed in separate
 precleaned jars for the required analyses at that station and for providing split samples for the
 Tribe's Environmental Program.

 4.1.2 Water

 4.1.2.1 Surface Water

 The surface water samples were taken in precleaned glass jars or cubitainers appropriate for the
 analysis required. The containers were filled with water at each station either by direct  immersion
 under the surface or with a precleaned 8-oz jar used as a ladle for filling larger containers.  Any
 surface debris  (e.g., floating algae, leaves, twigs, etc.) was brushed aside during sampling.
 Separate water samples were taken for the Tribe.

 Field parameters (pH, conductivity, and temperature) were measured at the time of sampling. In
 addition, a conductivity survey was made of the stream adjacent to the dump site. The  purpose of
 the survey was to measure conductivity variations that would indicate an increase in dissolved
 solids resulting from seepage from the base of the dump into the stream.

 4.1.2.2 Drinking Water

 Three groups of samples were collected for the drinking water sampling event (Table 4): first-
 pour samples for lead analysis, flushed samples for complete inorganics, and flushed samples for
 microbiology.  Microbiological methods are described below.

Revision 3.0, January 17, 1997                                                     Page: 24 of89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994- 1995
 First-pour samples for lead analysis (Table 4) were collected from 32 stations by residents using
 500-ml polyethylene cubitainers. Residents were provided a written protocol for collecting a
 sample early in the day from a tap commonly used for drinking water, generally the kitchen tap.
 The protocol specified collecting water prior to any other water use for the day to ensure that the
 sample was worst-case in terms of prolonged stagnation time irThousefiold^pipes.  The residents
 delivered their samples to a central receiving point during October 23-24, 1995, at which time
 field pH and conductivity were measured and the sample was preserved. Five of the samples were
 collected after the field survey and were subsequently mailed to the laboratory.

 Flushed samples for complete inorganic analyses (Table 4) were collected from 20 stations by an
 EPA team.  These samples were collected in polyethylene cubitainers after purging the tap for at
 least one minute. Field parameters (pH, conductivity, and temperature) were measured at the
 time of sampling, and samples were immediately preserved for metals analysis.  Since the flushed
 samples were collected later in the day after a period of normal water use, the sample water
 should have had minimal residence time in the household pipes, and should have been more
 representative of water from the outside distribution system. In addition to building taps, samples
 were collected from two well heads: the main tribal water-supply well and a tribal well near Toke
 Point (Figure 5).

 In order to test field conditions during the drinking water sampling event, a duplicate QA sample
 was collected at one station. In addition, a transfer blank was also collected at one station, for
 which laboratory- prepared deionized water was transferred in the field from  one bottle to
 another.

 4.1.3  Microbiology

 4.1.3.1 Field Methods

 All bacteriological samples of freshwater, seawater and leachate seep water were collected
 according to EPA and American Public Health Association (APHA) methods (12),(13),(14),(15)
 using sterile 250 ml or 500 ml polypropylene bottles containing the appropriate preservative.
 Leachate seeps and freshwater from the dump site were collected in bottles containing a chelating
 agent (0.3 ml of a 15% ethylene diamine tetraacetic acid (EDTA) 7125 ml sample volume). All
 other freshwater samples, including drinking water, were collected in bottles containing a
 dechlorinating agent (0.1 ml of a 10% sodium thiosulfate solution/125 ml sample volume).

 Shellfish samples consisting of Pacific oysters (Crassostrea gigas), Japanese littleneck clams
 (Tapes japonicd) and razor clams (Siliqua patuld) were collected according to APHA shellfish
 procedures (13) in sterile plastic bags.  Ambient estuarine surface water was collected near each
 shellfish bed by immersing a polypropylene bottle below the water surface.

 Freshwater, leachate, shellfish and seawater samples were examined within  eight hours of
 collection, and the  drinking water samples were examined within 30 hours of collection.
Revision 3.0, January 17, 1997                                                     Page: 25 of 89

 4.1.3.2 Laboratory Methods

 Drinking water samples were analyzed by the membrane filter method following EPA criteria (12)
 for the enumeration of total coliforms, fecal coliforms and E. coli.  All other samples, including
lihellfislTtissue, were examinedUsing thelfive-tube, multiple^iluTioirJ^NTtieTho^^utlmedirfbotlr
 Standard Methods (15) and APHA shellfish procedures (13).  Enterococci were determined by
 the same MPN procedure as described above using azide-dextrose broth for presumptive growth
 and Enterococcosel® Agar for confirmation as described in Standard Methods (12). All final
 counts for total coliforms, fecal coliforms, E. coli and enterococci were based on a per 100 ml/gm
 basis.
 Samples of leachate and freshwater from the dump site were examined by the heterotrophic plate
 count (HPC) and sulfite polymyxin sulfadiazine (SPS) aerobic/anaerobic procedure developed by
 the EPA Manchester Laboratory (16). All final counts of HPC and SPS were expressed on a 1 ml
 or 1 gm basis.
 4.2  Station Locations by Global Positioning System

 The position of each station was determined by using a global positioning system (GPS) in the
 autonomous (non-differentially corrected) mode. The positions of all stations, except for stations
 10, 11, 13 and 14, were post-processed to obtain final positions accurate to within ± 3 meters.
 Due to limited sampling time, position files were not recorded for stations 10, 11, 13 and 14.
 Further, in some other cases, e.g., stations 1, 2, 3, 4, 8 and 9, the recorded position was some
 distance away from the station location, which was under a canopy of vegetation.  The post-
 processed and uncorrected GPS station positions are listed in Appendix H, Table H-l.
Revision 3.0, January 17, 1997                                                    Page:  26of 89

   Chapter 5.0  QUALITY ASSURANCE/QUALITY CONTROL RESULTS
 Quality assurance/quality control (QA/QC) requirements for the project were specified in two
 QAPPs (17),(18). For preparation of this report, each QAPP was reviewed in order to determine
 if project objectives and project data quality objectives had been met.
 5.1  Project Objectives and Data Quality Objectives (DQOs)

 The above referenced QAPPs state the following project objective:

 •     Conduct a Preliminary Field Screening Study to:

              1) Evaluate a broad spectrum of organics, pesticides, and trace metals in selected
              sediment and water samples,

              2) Evaluate microbiological contamination of water and shellfish near the
              Shoalwater Bay Indian Reservation, and,

              3) Evaluate bacteria, metals, and other inorganic contaminants in on- and off-
              reservation household drinking water systems.

 The study area for the screening project includes a drainage pathway from a former dump site, an
 intertidal recreational swimming hole, intertidal areas where shellfish are collected as food, oyster
 beds recently treated with carbaryl, estuarine reference areas in Willapa Bay, a drainage pathway
 from cranberry bogs, and household drinking water on- and off-reservation and Grays Harbor.

 The DQOs of the preliminary field screening study were to collect documented, representative
 samples using a minimum number of resource-intensive QA oversight samples. Transfer blanks
 were collected for cation, anion, nutrient, and microbiological measurements of drinking water
 samples.  Trip blanks were collected for volatile organics compound (VOC) measurements.  A
 pair of blind field duplicate drinking water samples were collected for the measurement of metals,
 cations, anions, and nutrients in drinking water samples (see Appendix E, Table E-21).  The
 average percent difference (precision) of the two blind field duplicate drinking water samples for
 26 metals was 2 %.  Five project samples were measured in duplicate by the laboratory for metals,
 cations, anions, and nutrients (see Appendix E, Tables E-22 to E-24). In addition, the QAPPs
 required that the laboratory meet the QA and QC requirements which are specified in each
 analytical method.

 Finally, QAPP  objectives required that all project data be validated using EPA data quality
 assessment guidelines to determine if each measurement met the QA and QC requirements of both
 the QAPPs and the analytical method.  The result of this data validation process was the
 assignment of data qualifiers to selected project measurement values. Tables 5-17 show


Revision 3.0,  January 17,1997                                                     Page: 27of89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment,  1994 - 1995
 measurement results for target compounds which were reported to be above the lower
 quantitation limit of the sample.  Tables C-l to C-6 in Appendix C show the list of target
 compounds which were not measured in samples above the lower quantitation limit of the sample.
 The major use of the data for this limited, screening^tudy, islo provide a basis for the
 determination of a need of future environmental investigations, and to assist in the design of such
 investigations.
 5.2 QA/QC Samples

 Specific transfer blanks, trip blanks, and field duplicates were collected in order to demonstrate
 the integrity and precision of specific project samples.

 Project DQOs required that all quality control (QC) requirements for the measurement of all
 project samples meet the stated QC specifications of each analytical method.  These analytical
 methods required that the laboratory measure  method blanks, matrix spike (MS) samples
 (inorganics), matrix spike/matrix spike duplicate (MS/MSD) samples (organics), and sterility
 controls on transport/transfer blanks, dilution water blanks, media agar and broth blanks, and
 positive and negative control samples for microbiological measurements to ensure that results
 were within QC limits for each method. The laboratory also demonstrated laboratory precision by
 measuring duplicates of project samples.

 All QA and QC data from the measurement of both field and laboratory samples were used in
 assessing the quality of project data (see Appendixes D and E).  Any project data which did not
 meet the stated requirements of the QAPPs or analytical method was qualified with appropriate
 data quality flags (see Appendixes F and G).

 For organics data in this Report, the associated numerical value next to a "U" or "UJ" qualifier is
 the sample quantitation limit (SQL), which is based upon the lowest calibration point of the 5-
 point initial calibration curve and any dilutions which were made to the sample due to high
 concentrations or matrix effects.  For metals and.inorganic data in this Report, the associated
 numerical value next to a "U" or "UJ" qualifier is the method detection limit (MDL) for the
 sample, which is defined in 40 CFR Part 136, Appendix B.
5.3 Validation of Project Data

Project data were validated by the EPA Region 10 Laboratory. National EPA data validation
guidelines were used to determine the quality of organics data (19),(20) and inorganics data
5.4 Results from the Validation of Project Data

Using the objectives and criteria stated in the QAPPs and the data validation guidelines in Section
5.2 and 5.3, above, project data were validated by the EPA Region 10 Manchester Laboratory.
Validation results are documented in the Reference section of this report.

  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994- 1995	


 5.4.1  Data Quality Elements Used For Evaluation of Organics Data

 Organics data for each sample were evaluated and determined to be acceptable for the following
 data quality elements except as is noted, below:

        •     Holding Times and Sample Preservation

        •     GC/MS Tuning and Performance

        •     Initial Calibration

              Note that a five-point initial calibration was used for all samples except for
              phenoxy-acid herbicide measurements and the munition compounds measurements,
              which were from a three-point calibration

        •     Continuing Calibration

        •     Blanks  (see Appendix D for a listing of method blank results)

        •     Surrogate Spike Recoveries

        •     MS/MSD Samples (see Appendix E for a listing of MS/MSD results)

              The following target compounds had unacceptable recoveries in MS samples,
              therefore, results were qualified with an "R" flag:  dinoseb in samples 94334300 to
              94334304; dinoseb, acifluorfen, chloramben, and 4-nitrophenol in samples
              95080020 to 95080026; aniline, hexachloroethane, 4-chloroaniline, and
              hexachlorocyclopentadiene in sample 95080023; dinoseb, acifluorfen, and
              chloramben in samples 95080020 to 95080023 and in sample 95080025; dinoseb,
              acifluorfen, 4-nitrophenol, and chloramben in samples 95080024 and 95080026;
              and 5-hydroxydicamba, picloram, and dalapon in samples 95240104 and
              95240110.

              The average recoveries of demeton-o, demeton-s, and disulfoton were 244%,
              771%, and 249%, respectfully, in the ms/msd of sample 95080024. These target
              compounds were qualified with a "UJ" or "J" in samples 95080034 and 95080025.

       •      Internal Standard Performance

       •      Target Compound Identification

 5.4.3 Evaluation of Data Validation Reports

 Validation results are documented in the Reference Section of this Report (23-47).
 The EPA Region 10 QA Unit reviewed each data validation report foTcompleteness and
 adherence to written EPA data validation guidelines. All project results were determined to have
 been correctly qualified in the data validation reports and in the sample measurement results.

 In cases where more that  one qualifier was placed upon the data, the most restrictive qualifier was
 used to qualify the measurement value.

 In general, all project data which do not have an attached qualifier can be used to meet the
 objectives of the project and the corresponding QAPP.  The usefulness of qualified data  depends
 upon the severity of the qualifier, the nature of the sample, and the use of the data. The  final
 usability of the data is determined by the use of the data and the data user.

  The Shoahvater Bay Reservation: A Limited Environmental Assessment,  1994- 1995
                    Chapter 6.0  RESULTS AND DISCUSSION
 This limited study, designed to characterize four of the various pollution pathways which could
 reasonably be considered important to persons living in the area, focused on a relatively few
 sampling stations.  Direct contaminant exposure via air pathways, and possible long term
 contamination of ground water resources were beyond the scope of the study. Also, with the
 possible exception of drinking water household sampling, the relatively small number of samples
 limits the degree of certainty in assessing the likelihood of environmental risk which might be
 associated with these pollution pathways.  However, such an approach does provide an initial
 focus for screening out major chemical or microbiological problems and highlight issues which
 may exist in the four contamination routes investigated.

 The four basic pollution pathways considered in this assessment were: (See Figure 1)

       (1) Dump site, and its drainage to tidelands
              (chemical and microbiological screening of sediment and water)

       (2) Agricultural runoff from cranberry bogs toward tidelands
              (chemical screening for contaminants in sediment and water, focusing especially
              on pesticides)

       (3)  Tideflat sediments and shellfish associated with nearby Tribal subsistence
              harvesting and mariculture
              (a) sediment screening  for chemical contaminants
              (b) water and shellfish tissue screening for microbiological contaminants from
              leaking septic  systems.

       (4)  Drinking water supplies, at 32 separate households;
              (a) tap water screening for lead (32 samples) and other inorganic parameters (11
              samples)
              (b) source water screening for microbiological contaminants from leaking  septic
              systems.
6.1 Dump Site Drainage toward Tidelands (see Tables 5 to 8; Figure 2)

6.1.1  Metals in Dump Site Sediment (Stations #1, 3, 5)

Table 5 shows metal residues and basic water chemistry parameters for the dump site samples.
The upper dump site sediment (Station #1) was taken in an area rich in apparent leachate, but
surrounded by many discarded, rusting car bodies and other metal waste. Not surprisingly, this
sample was very high in iron (nearly 39 %; Table 5). The sediment sample from the lower
Revision 3.0, January 17, 1997                                                    Page: 49 of 89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment,  1994 - 1995
 part of this waste stream (Station #3) showed only about 2 % iron, with about 2.6 % iron in the
 sediment from the beach lagoon (Station #5).

 Lead was found in the upper sediment at 142 mg/kg (parts per million; ppm), decreasing to 18.1
 mg/kgurthelower sediment, and 1373 mg/kgln the sediment from thlTlower beach lagoon as thlT
 pathway progresses toward the sea.  For these samples, lead levels were well below the State of
 Washington's marine sediment quality standard of 450 ppm (dry weight) (48), and EPA Region
 10's risk- based criterion of 400 mg/kg, for urban soils (49). Total mercury levels were
 unremarkable in all three sediment samples, with respective findings of 0.02 and 0.03 mg/kg in
 Stations #1 and 3, increasing to 0.16 mg/kg in the beach lagoon sediment.  "Normal" background
 for total mercury in sediment ranges from 0.01 to 0.5 mg/kg (50).
 As with lead and especially iron, sediment concentrations of nickel, cadmium, and barium were
 significantly highest in the upper dump site sample (Table 5).  None of the levels exceeded EPA
 health based risk standards for residential soils.

 At the terminus of this pathway, the upper beach lagoon sediment sample (Station #5; see Table
 5; Figure  2) only arsenic, chromium and magnesium appeared at levels greater than either of the
 two sediment samples taken from the dump site path above it. Even so, the levels of these three
 metals were well below EPA's health based risk numbers for residential soils (51). Again, most of
 the remaining metals, including lead and mercury, showed declining trends in the sediment taken
 from the lower part of this pathway (Station #5) as it approaches the sea.

 Beryllium was present above the MDL, but not quantifiable, in all three sediment samples (Table
 5). Normal background levels for beryllium in sediment are  not available in the literature.
 However, EPA's risk based numbers for beryllium in urban soil and residential soil respectively,
 are 0.67 and 0.15 mg/kg (51). The MDL for the three samples ranged from 0.75 (Station #1) to
 0.37 (Station #3) and 0.42.

 6.1.2 Metals in Dump Site Water (Table 5)

 Compared with the aqueous sample taken at the upper part  of the dump site (Station #2; Figure 2,
 Table 5), the aqueous sample (Station #4) taken along the lower reach of the same stream shows
 a significant decline in all metals except aluminum (which increased about ninefold), and lead (a
 slight decline from 1.93 to 1.12 ug/1).  The increase in dissolved aluminum could be a result of the
 dumping of spent aluminum containers in the vicinity.  Sample #4, was extracted and analyzed
 twice as a QA /QC duplicate, generating two sets of data for most of the analytes evaluated at this
 station (see Appendix E).

 Both calcium and alkalinity also decline greatly in the lower aqueous sample, by a factor of
 approximately 13. This roughly parallels an approximately thirteenfold decrease in iron. Sulfate
 levels also decreased nearly fivefold in the lower water sample.

 Primary drinking water maximum contaminant levels (MCLs) or maximum contaminant level
 goals (MCLGs) were not exceeded in the two water samples from the dump. Other than iron and
 lead in Sample #2, and zinc in both samples 2 and 4, ambient water quality criteria for aquatic life
 were npt exceeded. In Sample #2, iron exceeded the freshwater acute criterion for aquatic life by

Revision 3.0, January 17,1997                                                   Page: 50 of 89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994- 1995
 about eightfold. Lead in Sample #2 was 1.93 ug/1, slightly above the chronic freshwater criterion
 for lead of 1.32 ug/1 (52). Zinc was noted in Sample #2 at 237 ug/1, and in Sample #4 at 59.5
 ug/1. Freshwater aquatic life criteria for zinc are 65.4 ug/1 (acute) and 58.9 ug/1 (chronic) (52).
 For beryllium in the aqueous samples, the MDLs were at 0.3 ug/1, well belowlheTiPA Drinking
 Water MCL of 4 ug/1 for this metal (53). Beryllium MDLs were not sufficiently low to address
 the (very conservative and much lower) EPA risk based modeled concentration of 0.016 ug/1,
 which is modeled on carcinogenicity (51).

 Manganese was  measured in both water samples, at 141 and 27.4 ug/1, respectively. The
 secondary MCL for manganese, based on taste and odor and not health effects, is 50 ug/1 (53).
 Freshwater ambient water quality criteria have not been established for manganese.

 6.1.3 Organics in Dump Site Sediment (Table 6)

 Residues of organics measured in the dump site sample pathway are shown in Table 6 and are
 discussed below.

 6.1.3.1 Polyaromatic Hydrocarbons (PAHs)

 In the upper dump sediment sample (Station #1), trace levels of the PAHs, pyrene (255 ug/kg),
 fluoranthene (227 ug/kg), anthracene (47.1  ug/kg, estimated) and fluorene (42.2 ug/1, estimated)
 were noted. All  four of these PAHs are ubiquitous products of combustion of organic matter.
 No such combustion-related PAH residues were measured in the lower sediment (Station #3).
 However, the upper SQL for anthracene in this sample was a relatively high 66.6 ug/kg, which
 would have not been sufficient to detect anthracene in Sediment Sample Station #1. At the
 terminus of the sampling for the dump pathway, fluoranthene (noted in Sample #1) re-occurred at
 a lower estimated concentration, 57.3 ug/kg. No other PAHs were noted in the sediment at the
 lower beach lagoon.

 Dibenzofuran, also associated with combustion of organic material, was estimated at 43.6 ug/kg
 in the upper sediment sample, but was not detectible in the two sediment samples from lower in
 the pathway.

 Retene (also called phenanthrene, l-methyl-7-isopropyl) was found in Sediment Sample #3 (lower
 dump), at 332 ug/kg.  Retene is a "resin acid" associated with wood pulp and paper processing,
 and is normally found in pulp mill effluent. Retene was not measured in the upper sediment
 sample from the dump (SQL =152 ug/kg).  However, retene was measured once again at the
 terminus of the dump site pathway sampling, in Sample #5 (upper beach lagoon), at  estimated
 levels of 51.1 ug/kg.

 In the upper sediment, 4-methylphenol (p-cresol) was estimated at 51.3 ug/kg. Although not
 measured in the lower dump sample, the residue of 4-methylphenol increased to 175 ug/kg at the
 lower lagoon sediment. This compound is associated with auto and diesel exhaust, coal tar, and is
 also a natural product which occurs in plants (e.g.,  anise  seed oil).
Revision 3.0, January 17, 1997                                                    Page: 51 of 89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994- 1995
 Sediment samples 1 and 5 also revealed trace estimated levels of chloroform at 2.2 and 1 ug/kg,
 respectively. Since chloroform is both an industrial solvent and a natural product sometimes
 associated with plant matter, it is difficult to speculate about the source of this material.
 6.1.3.2 Pesticide
 Trace residues of the organochlorine pesticide metabolite, endrin ketone (57 ug/kg) were
 measured in sediment Sample #1.  Endrin is a highly toxic and bioaccumulative organochlorine
 insecticide, whose agricultural uses have been greatly limited in the past decade because of
 toxicity to non-target organisms. However, such a finding of 57 ug/kg in dump site sediment is
 far below EPA's risk based endrin guideline of 23,000 ng/kg for residential soil (51). It would
 thus appear of only minor significance in this drainage, especially since no levels of endrin or its
 breakdown products were measured in the other two sediment samples taken further down the
 dump site pathway's seaward progression.

 Estimated residues of the DDT series (mostly p,p'-DDD, at 132 ug/kg, with 35 ug/kg p,p'-DDE
 and 32 ug/kg p,p'-DDT) were also noted in sediment Sample #1 from the upper dump site
 pathway.

 ODD was not measured in Sample #3, but was estimated at 10 ug/kg in the beach lagoon
 sediment. DDE was  estimated at 9 ug/kg in Sample #3, and at 16 ng/kg in the beach lagoon
 sediment sample.  p,p'-DDT was measured only in Sample #1, and did not appear lower down in
 the pathway.

 For an agricultural area, and especially a dump site, these concentrations for the DDT series are
 certainly within reasonable background.  The health based EPA risk concentrations for residential
 soil for ODD, DDE, and DDT are 2700, 1900, and 1900 ng/kg, respectively (51).

 In sediment sample 3, a trace of endosulfan sulfate, a metabolite of the organochlorine pesticide,
 endosulfan (thiodan), was measured at an estimated 22 ug/kg.  No endosulfan-derived residues
 were noted in the other two sediment samples from the dump drainage.  EPA's health-based risk
 concentration for  endosulfan in residential soils is 470,000 ng/kg (51).

 Traces of the carbamate insecticide carbofuran (furadan; 7.2 ng/kg) and its metabolite 3-hydroxy
 carbofuran (18.1 ng/kg), were noted in the upper beach lagoon sediment.  Another carbamate
 pesticide, mercaptodimethur (methiocarb; mesurol; often used to control snails, slugs, various
 insects, and also as a bird repellant) was measured in the lagoon sample 5 at 21.9 ug/kg. No
 carbamate pesticide residues were found in the two sediment samples taken from the upper and
 mid portions of the dump site drainage.

 Phthalates (from plastic waste) were not measured in any of the three sediment samples, but the
 SQLs (especially for di-N-butyl phthalate) for sediment were quite high. The analysis would have
 been unable to detect any trace levels which might have otherwise been notable. However, two
 common phthalate compounds were found in both water samples taken from the dump stream
 (see below).

 Ordnance compounds were not measured in any  sample.

 6.1.3.3 Two Novel Bromo and lodo Compounds; Natural Products?
        (See also Section 6.3.1.2.2)

 Laboratory analysis (Table 6) revealed compelling evidence of the presence of two apparently
 ubiquitous halogenated compoundslrffhe sediments taken from thlTdump sitfTdrainage. TheWo
 compounds are 4-hydroxy-3,5-dibromobenzoic acid (DBBA), and 4-hydroxy-3,5-diiodobenzoic
 acid (DIBA).  There was evidence that DBBA was present at an estimated concentration of 19
 Hg/kg, in the upper sediment sample from the dump pathway, and at 9 ng/kg in the lower
 sediment sample. It then was estimated with certainty (J) at 234 ng/kg in the sediment sample
 from the terminus of the pathway; the upper beach lagoon. DIB A was not noted in the upper
 dump sediment (Sample #1, SQL of 127 ng/kg). However, it was estimated as likely (NJ;
 occurring at 61 ng/kg) in Sediment Sample #2, and found with certainty at an estimated 70
 in the upper beach lagoon sediment below the dump.
 The significance of these two halogenated compounds is not clear.  The mass spectral properties
 for DBBA and DIBA, mimic those of the two synthetic herbicides, bromoxynil (3,5-dibromo-4-
 hydroxybenzonitrile,  DBBN) and ioxynil (3,5-diiodo-4-hydroxybenzonitrile, DIBN),
 respectively.

 As discussed later in the section 6.3.1.2.2, DBBA, DBBN, DIBA, and DIBN were also found in
 all seven tideflat sediment samples. Marine natural products containing bromine and iodine are
 commonplace (54),(55). However the presence of DBBA and DIBA at low levels in freshwater
 ecosystems like the sediment taken from the Dump Pathway poses several additional questions.
 Rationale for assuming DBBA and DIBA to be most likely natural products will be discussed in
 greater detail in the subsequent section on residues found in the sediments sampled from the
 Tideflats Pathway.

 6.1.4 Organics in Dump Site Water

 The aqueous samples from both the upper (Station #2) and lower (Station #4) portions of the
 dump site drainage revealed estimated traces of benzene at respective levels of 0.081 ng/1 (81
 parts per trillion; ppt), and 0.068 ng/1 (68 ppt). Both levels are well below the drinking water
 MCL for benzene of 5 jag/1 (53).  They are also well below the freshwater quality ambient
 criterion for human health (1.2 ng/1), based on ingestion of both water and aquatic organisms
 (56). Because the area around Station #1 was rife with discarded rusty automobile bodies which
 conceivably could still be leaking traces of fuel, this finding is not surprising.

 Traces of the PAHs, acenaphthene and fluoranthene (found in crude oil, and also combustion
 products), were estimated respectively at 0.017 and 0.01 jag/1 in the upper aqueous sample, but no
 PAHs were noted in the lower sample.

 Two phthalates frequently associated with plastic products such as bread wrappers and plastic
 bags were found in the water samples.  Sample #2 from the upper site had di-n-butylphthalate at
 estimated levels of 0.075 \ig/\.  Sample #4 from the lower part of the dump had diethylphthalate at
 an estimated level of 0.28 jxg/1.
Revision 3.0, January 17, 1997                                                   Page: 53 of 89

-------
  The Shoalwater Bay Reservation: A Limited Environmental Assessment, 1994- 1995
 Traces of dibenzofuran (combustion product) were estimated at 0.009 ug/1 in the upper aqueous
 sample 2, but were not found in Station #4 lower in the dump site drainage.

 Both water samples from the dump revealed the presence of residues of the chlorinated organic
 compound, bicyclo {2.2.1}hept-5-ene-2,3-dicarboxylic acid, 1,4,5,6,7,7-hexacHoro-, also known
 as chlorendic acid. It was estimated at 0.49  ug/1 in Sample #2, and at 0.56 ug/1 in Sample #4.

 Traces of the broad spectrum fungicide and wood preservative, PCP, were found in both water
 samples from the dump site drainage. PCP was estimated at 0.022 ug/1 in Sample #2, and at
 0.024 ug/1 in Sample #4 taken downstream.  Both findings are well below the EPA risk based
 concentration of 0.56 ug/1 for tap water (51), as well as below the MCL of 1  ug/1 (53). Both are
 also below the EPA freshwater criteria for aquatic life of 20 (acute) and 13 (chronic) ug/1, for
 PCP (57). In view of the long historical use  of PCP in wood treatment, such levels in water from
 a dump site drainage pathway would not appear unusual.

 Toxaphene, a complex and somewhat persistent chlorinated camphene with a long history of use
 as a "dip" for livestock, was estimated in Sample #2 at 0.82 ug/1. This is below EPA's drinking
 water MCL of 1 ug/1 for toxaphene (53). However it exceeds EPA's risk-based toxaphene
 concentration for tap water (conservatively modeled from animal data, using carcinogenic slope
 factor and numerous statistical assumptions), which is 0.061 ug/1 (51). Toxaphene was not
 measured in the lower water sample from the dump drainage, nor was it found in any of the three
 sediment samples.  However, it should be noted in all sediments—especially Sample #1  and
 Sample #5, the SQLs for toxaphene were unfortunately very high.

 Tentatively identified organics (TICs) from all five dump samples are shown in Table 7.

 6.1.5 Concurrent Environmental Investigations on the Reservation: The "livestock
 dipping station"

 The finding of low levels of a pesticide like toxaphene in the dump drainage water is not
 altogether surprising, in an area where livestock ranching is common. As is the case with many
 rural areas, at least one former ranching site near the Reservation is known to have contained a
 "livestock dipping station". The property in question, located at 2406 Tokeland Road, was
 purchased in  1994 by the Tribe to serve as a future housing development.  In compliance with
 various BIA and Inter-Tribal Housing Authority land use requirements, a site inspection was
 performed by a private contractor in March,
 1995, during which soil associated with the former dipping site was obtained and tested for
 various organics and metals.  The results indicated the presence (above background) of lead, total
 petroleum hydrocarbons (TPH),  diesel, TPH-oil, and the following pesticides: heptachlor,
 lindane, heptachlor epoxide, 4,4'DDD, 4,4'DDT, 4,4'DDE, and chlordane.  This screening test did
 not specifically include toxaphene.  (58).

 Based on these findings of pesticide residues, EPA Region 10's Office of Environmental Cleanup
 tasked Ecology and Environment, Inc. to conduct a removal assessment at the site. This
 assessment took place on August 13, 1996, concentrating on the area surrounding the cattle
 dipping station (59). A total of four ground water samples and seven subsurface soil samples
 (from zero to  six feet below ground surface) were analyzed, using field screening immunoassay

Revision 3.0, January 17, 1997                                                   Page:  54 of 89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment,  1994 - 1995
 test kits.  To verify the field immunoassay results, two field representative soil /water duplicates
 and additional soil and ground water samples were also sent to a commercial laboratory for
 independent analysis for pesticide residues.
 For the ground water samples, no pesticides were detectedlibove the instrument detection limits,
 and metals appeared consistent with the background sample and with the geology of the area
 (higher than normal arsenic concentrations). However, seven of the various soil samples
 contained levels greater than the EPA Region III risk-based concentrations (51) for one or more
 of following pesticides: alpha /beta /gamma /delta BHC; alpha /gamma chlordane; the DDT series,
 and heptachlor /heptachlor epoxide.

 A sample of the water taken directly from the dip tank revealed respective levels of alpha BHC
 and delta BHC at levels of 0.23 and 0.21 ug/1.

 Since the area is proposed as housing development for the Shoalwater Tribe, EPA Superfund
 Technical Assessment and Response Team has recommended a removal action, based on the
 concentrations of pesticides above the Region III risk based concentrations for soils, to reduce the
 threat to human  health and the environment (59).

 6.1.6 Microbiology: Dump Site Water and Leachate

 Table 8 shows results of microbiological analysis of three aqueous samples taken from various
 points along the dump site drainage stream (see Figure 2).

 Although E. coli numbers were comparable in both water samples, other bacterial indicators (total
 and fecal coliforms, and enterococci) were present in highest numbers at the spring head located
 at the origins of the small creek passing through the dump site (Station #16A). This may have
 been due to some agitation of sediment at the time of collection, or to the presence of toxicants in
 the leachate which can have bacteriostatic or bacteriocidal effects. Exposure to such substances
 could significantly alter the numbers and types of bacteria present in the leachate and post-
 leachate samples. In either case, there did not appear to be  an abundance of indicators present in
 the leachate.

 The purpose of the anaerobic/aerobic ratio (Table 8) is to establish the condition of the dump. An
 older, ideally operating dump that is composting well, should demonstrate a ratio of greater than
 1. This ratio also describes the condition of the collected leachate, The area of the dump where
 this leachate was collected (Station #15) was composed mainly of rusty appliances and old car
 bodies.  There appeared to be little  organic material present. This collection station may not be
 representative of the entire dump, but it was the only obvious site of leachate runoff.

 Of interest is the presence of Clostridium perfringens at the leachate collection Station #15. Pure
 isolates of this organism obtained from the leachate sample were tested for the presence of
 enterotoxin by reverse passive latex agglutination (Oxoid-PET-RPLA toxin detection kit). In this
 assay, Clostridium perfringens toxin was not detected. This organism is an opportunistic
 pathogen, and a causative agent of wound infections in humans,  including "gas gangrene".  Its
 presence is not indicative of anything in particular except perhaps continued anaerobic
 decomposition and long term organic contamination.  However, since the organism's presence has

Revision 3.0, January 17, 1997                                                     Page: 55 of89

 been confirmed at this station, care should be taken to protect against puncture wounds if any
 further sampling is done.

 6.1.7  Conductivity Survey at the Dump Site

 As part of the field measurements during sampling, an electrical conductivity survey of the stream
 that traverses the base of the dump was made on February 21, 1995. The objective of the survey
 was to use conductivity as an indicator to identify the extent of increased dissolved solids from.
 dump leachate impacting the stream. Figure 7 shows the results of the survey. Six points were
 measured in the stream, two in an eastern tributary, two in adjacent marsh ponds, and one in an
 area of leachate discharging from the southern down gradient margin of the dump (Sample
 Station #2 referred to as upper dump site). During sample collection on February 22, additional
 measurements of conductivity and pH were measured at Station #2 (leachate/upper dump);
 Station #4 (downstream/lower dump); and Station #5 (slough), and are shown in Figure 8.

 The conductivity of the stream upgradient of the dump was 128  microsiemens (uS), comparable
 to the value of 125 nS found in an eastern tributary unaffected by dump seepage (Figure 8).  As
 the stream traversed the base of the dump, conductivity increased to 160-174 uS indicating
 increased concentrations of dissolved solids.  Conductivity measurements of dump leachate at
 sample Station #2 were 692-736 ^S, about 5-6 times the values for the stream upgradient of the
 dump.  Based on mass balance, the increase in stream conductivity below the dump, compared
 with dump leachate, suggests that about 8% of the stream flow below the dump was contributed
 by dump leachate.  Conductivity measurements shown in Figure 8 for marsh ponds down gradient
 of the dump suggest that they were also impacted by dump leachate, compared to ponds
 upgradient of the dump.

 Inspection of the major inorganic parameters (Table 5) shows that dump leachate at the time
 sampled (Station #2) was a calcium bicarbonate water with a pH of about 7. As the stream that
 traversed the dump approached tidewater (lower Station #4), the major ion content changed to a
 sodium chloride water with a pH of 6.9. See section 6.4.1.2 for  additional discussion of the
 general inorganic characteristics of dump  site water in comparison with other water types sampled
 in this study.

In general, metal residues noted in the two sediment samples from the cranberry drainage ditch
were all lower than those seen in the lower beach lagoon (Station #5), and markedly lower than
either of the sediment samples taken from the upper and mid portions of the dump site drainage.
With the exceptions of arsenic (slight elevation), and manganese and barium (levels remained
relatively constant), all metals in Sediment Sample #6 from the upper drainage ditch appeared in
concentrations less than those detected in sediment for the lower beach lagoon. Sediment.metals
also appeared to decline as a function of distance from the agricultural lands.  Based on the more
seaward sediment  sample (Station #8), nearly all metals  had declined further from the

 concentrations noted at the upper part of the drainage path immediately below the cranberry bogs
 upstream.  Exceptions to this pattern were nickel (slight increase, from 8.57 to 10.7 mg/kg,
 sodium (about a twofold increase, probably due to seawater intrusion and tidal influences), and
 potassium (levels remained constant). Except for selenium, all sediment concentrations were
 approximately within the mean sediment concentrations ("expected background") lisfecTby Bowen
 (1979) (50). The  selenium concentrations (an estimated 6.4 and 10 mg/kg) measured in the two
 samples were 15 and 23 fold greater than Bowen's "expected background " concentration.

 6.2.2  Pesticides in Drainage Ditch Sediment  (Table 10)

 Both of the sediment samples from the drainage ditch appeared relatively unremarkable in terms
 of the variety and amounts of pesticide residues measured. The upper sediment sample (Station
 #6) contained estimated concentrations of the herbicide dichlobenil (2,6-dichlorobenzonitrile;
 casoron) at 10 jag/kg. Traces of dichlobenil were also estimated in the lower sediment sample
 (Station # 8) at 1.5 jag/kg.  Traces of the four major DDT metabolites were also noted in the
 upper sample. The sum of these residues (total DDT) was estimated at 123.5 jag/kg (Table 10).

 In the lower sediment sample (Station #8), only p,p'-DDD was found, at an estimated
 concentration of 3 jag/kg.  No other pesticide residues were found in either sediment sample, nor
 were any other organic compounds measured.

 6.2.3  Pesticides in Drainage Ditch Water (Table 10)

 Somewhat paradoxically, both water samples displayed a much greater variety and extent of
 pesticide contamination than did the corresponding sediment samples taken at the same place
 (Figure 2 and Table 10). At the lower station (Sample #8), the substrate appeared to be a clear,
 hard sand that may not have accumulated pesticide residues. This issue is explored in more detail
 in later portions of this discussion.

 6.2.3.1 Herbicides

 As in the case of both sediment samples, both water samples showed traces of the herbicide
 dichlobenil, measured at 1.9 jag/1, and 2.0 ng/1, respectively, in samples 7 and 9.
 Dichlorbenzamide, which is a breakdown product of dichlobenil, was also noted at 0.14 jag/1 in
 both water samples. Dichlobenil is registered as an herbicide for weed control in cranberry areas.
 It is also sometimes intentionally applied to water. According to the Weed Science Society of
 America, the halflife for dichlobenil in water under limited sunlight is 10.2 days (60).   96 hr LC50
 for rainbow trout is from 4930 to 6260 jag/1 (60).  Neither a drinking water MCL nor an ambient
 water quality criterion exists for dichlobenil at this time. Since the levels noted in these water
 samples are more than three orders of magnitude below the 96 hr LC50 for sensitive  salmonids,
 the levels of dichlobenil and dichlorbenzamide would not appear to be of concern.

 The carbamate herbicide chlorpropham (isopropyl-3-chlorophenyl carbamate; CIPC)  was also
 noted in both water samples, at estimated levels of 0.1 ng/1 for each. According to the Farm
 Chemicals Handbook, the LC50 for chlorpropham (rainbow trout) ranges from 3020 to 5700 jag/1
 (61).
Revision 3.0, January 17, 1997                                                    Page: 59 of 89

  The Shoalwater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
 Napropamide, a substituted amide herbicide with a typical field halflife of about 70 days (60), was
 found in both water samples, at 0.2 jig/1. The Herbicide Handbook of the Weed Science Society
 of America indicates relatively low aquatic toxicity for this material citing a rainbow trout 96 hr
 LC50 of 16,600 jig/1 (60).	

 The herbicide norflurazon was also measured in both samples (Station #7 at 1.0 jig/1 and Station
 #9 at 0.78 jig/1). This herbicide has a moderate to long halflife of approximately 6 to 8 months in
 aerobic aquatic conditions, according to the Herbicide Handbook (60). The 96-hr LC50 for
 rainbow trout is listed at 8100 jig/1 (60).

 Both water samples also contained residues of the herbicide,  2,4-D. 2,4-D was measured at 0.12
 jig/1 in the upper ditch water and again in the lower ditch water sample at 0.091 jig/1. Ambient
 water quality criteria for 2,4-D have not been established at this time.   The EPA drinking water
 MCL for 2,4-D is 70 jig/1 (53), and the EPA risk-based modeled estimate for permissible levels in
 tap water is 61 jig/1 (51). The rainbow trout 96-hr LC 50 for the isooctyl ester of 2,4-D is greater
 than 5000 jig/1. Comparable 96-hr toxicity levels for technical grade 2,4-D acid and 2,4-D-
 dimethylamine salts are about 377,000 jig/1, and 250,000 jig/1, respectively (60).

 Triclopyr ([(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid; garlon) was also estimated in both upper
 (0.28 jig/1) and lower (0.023 jig/1) water samples from the cranberry runoff ditch. No drinking
 water MCL or ambient water quality criterion have been established for this herbicide.  Although
 soil halflife averages about 30 days, triclopyr is rapidly degraded by photolysis in water, with a
 halflife at  10 hours at 25 degrees C, producing trichloropyridinol as a major metabolite (60).
 Chronic toxicity to  aquatic organisms is quite variable, depending on the chemical species of
 triclopyr in question. Rainbow trout  96 hr LC50 for the technical acid form of triclopyr is
 117,000 jig/1, while the comparable LC50 for the triethylamine salt is only 552,000 jig/1.  In
 contrast, 96 hr rainbow trout LC50 for the butoxyethyl ester of triclopyr is 740 jig/1 (60).

 6,2.3.2 Insecticides

 DDT Series: Similar to the two sediment samples, p,p' ODD  was estimated in both corresponding
 water samples at 0.0088 jig/1 at (upper) Station #7, and  again at 0.01 jig/1 at (lower) Station #9.
 These levels exceed the Washington State Ambient Water Quality Standards of 0.001 jig/1 for
 total DDT (62). No other residues of the DDT series were noted in the two water samples.

 Carbamates:  The systemic broad spectrum insecticide /nematicide, carbofuran (furadan; 2,3-
 dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate), was measured in both water samples at
 0.43 jig/1 (Station #7),  and 0.35 jig/1 (Station #9).  Carbofuran has a drinking water MCL of 40
 jig/1 (53). The EPA risk-based number for carbofuran in drinking water is 180 jig/1 (51). No
 EPA ambient water quality criterion has been established for this pesticide. However, a Canadian
 water quality guideline of 1.75 jig/1 has been noted in the available literature (63). The 96 hour
 LC50s for carbofuran range from 240 jig/1 (bluegill) to 380 jig/1 (rainbow trout) (61).

 Organophosphates:  Significant findings for three organophosphate pesticides were noted in both
 water samples.  Of special concern was the detection of significant trace residues of the extremely
 toxic cholinesterase inhibitor, azinphos-methyl (guthion), in both water samples. A level of 0.21
 jig/1 was found in (upper) sample 7 and 0.22 jig/1 was measured in (lower) sample 9.  These levels

Revision 3.0,  January 17,1997                                                     Page: 60of 89

-------
    The Shoalwater Bay Reservation: A Limited Environmental Assessment, 1994-1995
   are more than an order of magnitude above the chronic EPA ambient water quality criterion of
   0.01 ug/1 for guthion (57), and likewise exceed water quality standards for the State of
   Washington (62). Although no drinking water MCL has been established for guthion, its extreme
	acute mammalian toxicity (oral rat; approximately 4 mg/kg)(61) makes it potentially one of the
   most hazardous of all organophosphate pesticides in use today. Consequently, any residues in
   surface water which might come in contact with aquatic life, or with incidental human wading or
   swimming activity should be of concern.

   Chlorpyrifos, which is of increasing environmental concern because of its relative persistence and
   moderate to high toxicity, was also found in both samples. The upper water sample (Station #7),
   was estimated at having 0.044 ug/1, and 0.046 ug/1 was estimated for the lower water sample
   (Station #9). Both levels exceed the chronic Washington State Water Quality Standard of 0.041
   ug/1 for this pesticide (62).  The National Academy of Sciences (NAS) has also recommended a
   maximum concentration in ambient waters of 0.001 ug/1 for chlorpyrifos (64).

   Diazinon, a moderately toxic organophosphate, was also measured in both water samples.
   Sample #7 had 0.23 ug/1 diazinon, and Sample #9 contained 0.27 |ig/l.  EPA has not established
   ambient water quality criteria for this pesticide but the NAS has recommended a maximum
   concentration of 9 ug/1 (64). EPA's lifetime health advisory for diazinon in drinking water is 0.6
   ug/1 (53).

   These findings confirm concurrent studies by the State of Washington, which during both 1994
   (65) and 1995 (66) have measured these same three organophosphate pesticides in a similar
   cranberry bog drainage at values which either exceed USEPA criteria or Washington State water
   standards for water quality, or are in excess of the NAS recommendations for maximum
   concentrations in surface waters. In 1994, the Washington State Pesticide Monitoring Program
   also noted similarly excessive levels of these three pesticides in water samples collected
   throughout much of the growing and harvest seasons from Grayland Ditch No. 1 (segment no.
   WA-24-1030), which originates in Long Lake and flows to North Cove in Willapa Bay. Their
   findings reported azinphos- methyl at 0.14  ug/1 in Grayland Ditch water during sampling in June,
   1994 (65). (USEPA Water quality standard is 0.01 ug/1) (57).  Their study also found
   chlorpyrifos  residues in Grayland Ditch water at 0.021 ug/1 (June, 1994), and again  at 0.03  |ig/l
   (October, 1994) (65).  Although this is within the current Washington State water quality
   standard of 0.041 |ig/l for this pesticide (62), it is well above the NAS recommended maximum
   level of 0.001 |ig/l (64). The Washington State monitoring effort also measured diazinon residues
   in Grayland Ditch at 0.011  ug/1 (April,  1994) and again at 0.029 ug/1 (October, 1994) (65). Both
  values exceed the NAS recommended maximum concentration of 0.009 ug/1  (64).

  During 1995, the Washington State pesticide water monitoring data for Grayland Ditch No. 1
   continued to reveal consistently elevated concentrations of the same three organophosphate
  pesticide residues (66).  Azinphos-methyl was detected in the 1995 water samples at 0.21 ug/1
   (June), 0.48 ug/1 (August),  and 0.018 ug/1 (October). Respective  1995 (ug/1) findings for
  chlorpyrifos in Grayland Ditch samples were 0.045 (April), 0.012  (June), 0.13 (August), and
  0.016 (October). Comparable (ug/1) 1995 findings for diazinon were 0.014 (April) 0.22 (June),
  0.68 (August), and 0.030 (October). The 1995 Washington State monitoring also revealed
  consistently elevated levels of total DDT in the Grayland Ditch water samples.  In ug/1, These

 were: 0.019 (April), 0.014 (June), 0.020 (August), and 0.017 October) (66). All were well above
 the Washington State water quality standard for total DDT, which is 0.001 ug/1 (62).

 The question of "sediment": The above discussion makes it clear that significant pesticide
 residues were found itf both water sampleslrom the cranberry drainage. However, a lingering
 question about these findings is the relative absence of pesticide residues in either of the two
 corresponding "sediment" samples (Table  10). Although most organophosphate pesticides are
 relatively labile (with the exception of chlorpyrifos, which can remain in environmental media for
 months), many if not all of the residues noted in water would be expected to also bind
 preferentially to sediment.
 Why, then, were so few pesticide residues noted from the two sediment samples in this study?  A
 possible explanation of this discrepancy is that the samples collected may have actually been
 "hardpan", which had been swept clean of fine particulates, rather than sampling true stream
 "sediment". While obtaining the field samples, it was noteworthy that the bottom of the drainage
 ditch was very hard and firm, making it difficult to obtain any benthic material at all without great
 effort in breaking into the hardpan surfaces.  It is possible that fine sediment particles are simply
 swept down the ditch, rather than being deposited uniformly on the bottom.
 6.3  Tideflat Sediments and Shellfish associated with nearby tribal subsistence harvesting and
 mariculture

 6.3.1 Sediment Screening for Chemical Contaminants  (Tables 11, 12, 13)

 Originally, five samples of sediment (#10, #11, #12, #13, and #14) were obtained August 8, 1994,
 from Willapa Bay tidelands (see Figure 3, Table 2). Two more intertidal sediment samples were
 obtained for comparative purposes the following year.  On February 21, 1995, sample #23
 (tideland in South Bay off Grays Harbor),  and February 22, 1995, sample #12A (a resampling of
 Sample #12; the Swimming Hole), were obtained.

 6.3.1.1  Metals (Table 11; Table 12)

 The results of metal and organometal measurements in the six Willapa Bay sediment samples, and
 the Grays Harbor "reference" sample #23 are shown in Tables 11 and 12.  Sample #23 was also
 measured as a field duplicate sample (see Appendix E). Organometal target compounds such as
 methyl mercury, which were not measured in Willapa Bay sediment samples, are listed in
 Appendix C, Table C-6.

 In general, metal residues detected in all seven samples were unremarkable, well within reasonable
 background, and well below existing sediment criteria (48),(67).  An interesting finding was that
 the Willapa Bay samples revealed lower residues than were noted in the single reference sediment
 sample from Grays Harbor.

 Organotin compounds were noted in trace levels at sediment samples #10 and #12 from Willapa
Bay. Sample #10 had an estimated 6.4 ug/kg of butyltin trichloride, and 8.8 ug/kg of tributyltin
 chloride. The sample at Station #12 (Swimming Hole) contained 21.6 ug/kg of dibutyltin

Revision 3.0, January 17, 1997                                                    Page: 62of89

  The Shodtwater Bay Reservation: A Limited Environmental Assessment, 1994 -1995
 chloride, and an estimated 1.4 ug/kg of tributyltin chloride. No organotin residues were measured
 when Sample #12 was resampled (as Sample #12A). The presence of organotins would not be
 unexpected in such an area, because of the historic widespread use of organotin compounds in
 anti-fouling paints on boat hulls. In terms of ecological effects to nontarget organisms, tributyltin
 is most toxic, followed by dibutyl and monobutyl tins (68).  ATfEslime, no specific sediment
 criteria for the various organotins have been set for marine sediment.  However, EPA Region 10
 currently uses a guidance level for tributyltin; tentatively established at 30 ug/kg as total tin (dry
 wt) (48),(69).  The levels of organotins noted for the two Willapa Bay samples would not be
 unexpected for sediment in typical harbors and marinas along Coastal Washington, but are
 probably above what might be considered "background" for this relatively well-flushed area.

 Methyl mercury was not measured in any sediment sample, but #12A showed a lower SQL of
 5.76 ug/kg.  The Grays Harbor sediment (#23) also showed a lower SQL (6.56 ug/kg). For the
 remaining five Willapa samples, SQLs for methyl mercury were unfortunately all very high,
 ranging from 110 to 170 ug/kg (see Appendix C, Table C-6).  Therefore no information about
 possible low levels of this compound could be obtained.

 Because of the uncertainty about methyl mercury being present at all, it is difficult to speculate
 further about any possible environmental impact.

 6.3.1.2 Organics (Table 12; Table 13)

 All seven Willapa sediment samples, as well as the reference sample from Grays Harbor, were
 relatively unremarkable in terms of organic contaminants measured. Specific comments about
 certain contaminants which were noted are as follow:

 6.3.1.2.1  The Swimming Hole

 Samples #12 and  12A were taken from the  Swimming Hole (Figure 3, Table 12; Table  13), which
 was of particular concern to the Tribe because of location very near the main Tribal Headquarters
 and its frequent use by children and subsistence fishers.  Station #12 sediment contained
 (estimated) 4.0 ug/kg  ethyl benzene, and 19.8 ug/kg carbon disulfide.  Ethyl benzene is commonly
 used in the process of making rubber, and is also a chemical precursor in the production of
 styrene. No ethyl benzene was measured in the second sample taken from this station.  Carbon
 disulfide was also measured in #12 sediment, at 19.8 ug/kg.  Although carbon disulfide is used in
 large quantities worldwide as an industrial chemical intermediate, it also occurs naturally at trace
 levels throughout the oceanic environment.  Carbon disulfide is especially common in marshlands,
 where it is produced by microbial reduction of naturally occurring sulfates.  Therefore, such a
 finding in nearshore marsh sediments is not  surprising. However, carbon disulfide was not
 measured in any of the other six sediment stations, from either Willapa Bay or Grays Harbor.

 Traces of trichloromethane (chloroform) were estimated at  1.1 ug/kg in one of the two samples
 from the Swimming Hole (Station #12A). Chloroform was also estimated at 0.06 ug/kg in the
 Grays Harbor reference sample, but was not noted in any other samples. Since chloroform is not
 only an industrial chemical but also a natural constituent of various plant material, it is difficult to
 speculate on the source of this material. These estimated trace levels, found in only two of the
 seven samples do not appear significant in terms of health or environmental risk.

Revision 3.0, January 17, 1997                                                     Page: 63 of 89

-------
  The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
 4-Methylphenol (p-cresol) was found in Sample #12A at 205 ug/kg, but was not measured in any
 of the other six Willapa Bay sediments.  Like trichloromethane, 4-methylphenol was also found in
 the Grays Harbor reference sediment, at an estimated 54.6 ug/kg. Possible sources of this
 chemical, especially the relatively high levels noted in the first sample taken from the Swimming
 Hdl(T(but not the second sampltTof tHis same station) are difficult to speculate upon. 4-
 methylphenol is a known constituent of automobile and diesel exhaust, and is a coal tar product.
 However, it is also a natural product of plants.  Although interesting, such trace levels are
 probably not significant in terms of health or environmental risk from this exposure pathway. In
 1994, hexachlorobenzene was also estimated at 10.3 ug/kg in the #12 swimming hole sample.
 This chemical is a common chemical intermediate in many industrial processes such as the
 manufacture of rubber and polyvinyl chloride (PVC) plastics.  It is also utilized as a fungicide.  In
 1995, hexachlorobenzene was not measured in the sediment sample (#12A) taken previously
 from the same station.
 Retene, a resin acid commonly associated with wood pulp and paper processing, was also found
 in Sample #12A, at an estimated 31.8 ug/kg. It was not found in the other sample from this same
 station, nor was it found in any of the other four samples from Willapa Bay, or in the Grays
 Harbor reference sample.

 Pyrene, a PAH associated with combustion of organic materials, was estimated in Willapa Bay
 Sediment Sample #10 at 17.2 ug/kg but was not measured in the other sediment samples.
 Fluoranthene, another PAH associated with the combustion of organic matter, was estimated at
 44.1 ug/kg in the Grays Harbor reference sample (#23).

 6.3.1.2.2  Two Novel Halogenated Compounds: DBBA and DIB A
       (see Table 12; see also Section 6.1.3.3)

 As noted in the three previously discussed sediments from the dump site drainage (see Table 6,
 Figure 2, Stations #2, #4, and #5), two unusual halogenated compounds were also measured in all
 seven Tideland sediments.  These two compounds were DBBA, and DIB A.  Both were present in
 all five original Willapa sediment samples collected on August 19, 1994. Both were also noted in
 a sixth Willapa sample taken six months later, in February, 1995.  Both were also found in
 February 1995 "reference" sediment taken subsequently from Grays Harbor  (Station #23).

 As discussed previously, the mass spectral responses of the novel compounds DBBA and DIB A
 and the synthetic herbicides, bromoxynil and ioxynil, are identical.  However, for reasons
 discussed later in this section, we hypothesize that these two compounds are most likely natural
 products, rather than actual herbicide residues applied intentionally to the ecosystem as
 xenobiotics (e.g., along roadsides to control weeds).

 Concentrations of DBBA and DBBN in the original five Willapa samples, (August 19, 1994),
 ranged from 10 ug/kg in Sample #13, to 205 ug/kg in Sample #12. Average concentration for
 DBBA and DBBN in the six Willapa samples was 95.1  ug/kg. Concentrations of its iodinated
 analogs, DIBA and DIBN, ranged from 44.0 (Sample #10) to 244.0 ug/kg (Sample #12), with a
 mean concentration for the six Willapa samples of 153.5 ug/kg.  Highest concentrations of all
 four analogs were found in sediment Sample #12 (but declined in the repeat sample of this station,
 #12A). Lowest concentrations for both compounds were found in Sample #13. In every Willapa

 sediment sample except #12A (in which levels of DBBA and DIB A were much lower, and nearly
 equal) concentrations of DBBA were always significantly greater than those of DIBA.

 Because of the presence of these two apparent "herbicide" analogs in all of the initial five Willapa
 sediments sampled in August of T9947six monthiTlater an additional two sediment sampler were
 obtained for further verification, from both Willapa Bay (Station #12A) and a geographically
 separate tideflats ecosystem (Grays Harbor; Station #23). (see Figures 1 and 3).  Sample #12A
 (Swimming Hole)  was again determined to be positive for both DBBA and DIBA, although at
 considerably lower levels than seen in the sample taken six months previously (#12) from that
 station. Even more surprisingly, the Grays Harbor sediment (#23) also contained residues of the
 same two compounds but in a reversed ratio from that usually seen the Willapa samples.  Sample
 #23 contained estimated concentrations of 231.0 ug/kg DBBA,  and 167.0 ug/kg DIBA. Reasons
 for reversal of this ratio in the Grays Harbor sediment are currently unknown.

 •     DBBA and DIBA: Natural Products?

 As mentioned previously, the  EPA mass spectral library tentatively identifies DBBA as an analog
 of the synthetic herbicide, bromoxynil.  It also identifies DIBA as analogs of the synthetic
 herbicide, ioxynil.  From our findings, however,  it appears most  likely that these four halogenated
 compounds, DBBA, DBBN, DIBA, and DIBN,  are natural products, rather than  xenobiotic
 compounds intentionally applied to the Willapa or Grays Harbor ecosystem as herbicides.
 Reasons in support of this premise are as follow:
       1. Estimated residues of the four analogs were found consistently in all six samples of
       marine sediment from Willapa Bay, as well as in the totally unrelated marine sediment
       sample taken from Grays Harbor; a separate large estuary thirty miles to the north.

       2. The synthetic herbicides, bromoxynil and ioxynil, are known to photolyze and
       biodegrade in the environment.  Bromoxynil normally does not persist in surface or
       sediments longer than six to eight weeks (70),(71),(72). Ioxynil is cited as having a
       halflife in soil of less than two weeks (73). Even at different sampling times six months
       apart, in late summer and mid-winter, both DIBA and DBBA were still always noted at
       significant levels, in every sample. This does not argue for the presence of an intentionally
       applied labile xenobiotic such as these two synthetic herbicides.

       3. According to Meister (1996) (61), ioxynil is not marketed as a herbicide in the U.S. at
       this time. Although bromoxynil is a common herbicide in U.S. agriculture, neither
       substance is known to be utilized for rights-of way or agricultural purpose in the Willapa
       Bay or Grays Harbor, or at the fall /winter season when samplings were conducted.

       4. Traces of DBBA and DBBN were also noted in both sediment samples (#1 and #2; see
       Table 6) from the (freshwater ecosystem) dump site drainage, as well as at 234 ug/kg in
       the sediment from the lower (marine ecosystem) beach lagoon (Sample #5).  Although
       DIBA was not seen in the upper dump sample, the minimum level of detectibility for that
       compound in that sample was 127 ug/kg. DIBA was, however found at 61 ug/kg in the
       lower dump sediment, and at 70 ug/1 in the lower beach lagoon sediment (#5). Levels and

Revision 3.0, January 17, 1997                                                   Page:  65of 89

        ratios of both DEB A and DBBA in the sediment sample (#5) from the lower beach lagoon
        (dump site drainage) are consistent with those seen in all six tideflat sediments taken from
        Willapa Bay per se.  Such ubiquitous occurrence also argues in support of a natural
        product  hypothesis.

 6.3.2  Microbiology

 6.3.2.1 Shoahvater Bay Shellfish and Seawater Evaluation (Table 19)

 The standard used by both the US Food and Drug Administration (FDA) and the Washington
 State DOH for regulating the consumption of molluscan shellfish is based on a fecal coliforms
 standard targeted at the overlying seawater in which shellfish exist.  For over twenty years this
 standard has been based on a geometric mean (GM) most probable  number (MPN) of 14 fecal
.coliforms /100 ml. Because of the variability of fecal coliforms in seawater, as measured by the
 MPN method, numerous samples must be collected over a protracted period of time at various
 stages of the tide before a valid  evaluation can be made. Consequently, the collection of one
 seawater sample and one shellfish sample can only give a brief snapshot of shellfish conditions at a
 given sampling locale.

 As shown in Table 19, razor clams collected at Willapa Bay's North Cove did exceed the market
 standard for non-depurated shellfish as described by FDA (13). Since the Geometric Mean MPN
 is used in establishing registered shellfish beds, the use of a single point test in determining the
 quality of water /shellfish is not  recommended.  Further testing of the shellfish and overlying
 seawaters would be required to  more fully evaluate the microbial safety of the shellfish. The level
 of fecal coliforms in nearby seawater was indeterminately low at <18 /100 ml.

Although total coliforms, enterococci, and marine heterotrophic plate counts (MHPC) are not
covered by either FDA or Washington State DOH shellfish growing water regulations, their
occurrence in seawater can often help delineate the "freshness" of coliform contamination and the
effects of rain water or snow melt runoff.  The closer together the total coliform and fecal
coliform values become, the more likely that contamination is due to recent fecal sources.
Conversely, the farther apart total coliform and fecal coliform values become, the more likely that
contamination is due to recent soil runoff.

Although based upon a single data set, the low total coliform and fecal coliform values found in
seawater at all three locations (Table 19) indicate a soil runoff issue  rather than a nearby fecal
source. However, more samples collected during or following a major rainfall event could
substantially alter this preliminary finding.

Another useful indicator of fecal contamination is the enterococcus group. Like fecal coliforms,
they indicate the presence of fecal contamination from warm blooded animals, but unlike fecal
coliforms, they survive longer in seawater. The combination of high numbers of enterococci, low
fecal coliforms and elevated total coliform measurements in littleneck clams collected from the
Tribal shellfish harvesting area point to long term contamination from aquatic animals and/or
insects possibly associated with nearshore vegetation. The high concentration of marine
microorganisms revealed via MHPC, tends to further confirm this observed association.

 Not surprisingly, the highest concentration of all bacterial indicators was found in shellfish rather
 than nearby seawater.  Bivalve shellfish, being filter feeders, have the ability to concentrate
 bacterial contaminants more than ten times above ambient background levels (74).
 6.3.2.2 Occurrence of Microbial Contaminants in Tribal "Swimming Hole" (Table 20)

 In Washington State, the bacteriological standard for recreational waters is fecal coliforms, and is
 based on a GM of 200 7100 ml and collection of a minimum of 5 samples per week.  Because of
 the variability of the MPN method, numerous samples must be collected over an extended time at
 various stages of the tide, before a valid evaluation can be made.  Therefore, collection of a single
 sample, as was done in this evaluation, will provide only an estimate of the actual risk. As shown
 in Table 20, the sample collected from the "Dexter-by-the-Sea" station (Sample #12) met State
 recreational standards for fecal coliforms.  Conversely the second sample near Davis house
 exceeded the State standards for fecal coliforms.

 The EPA recreational standard for E. coli in fresh water is  a GM of 126 /100 ml, assuming at
 least 5 samples are collected per week. Generally speaking, the use of an E.  coli standard for
 marine waters is not recommended.  However, in instances such as Station #12A, located north of
 the "Swimming Hole", where the fecal coliform and E. coli numbers are equivalent, these results
 further confirm that the bacterial contamination is of fecal origin rather than from soil or wood by-
 products.

 The EPA recreational  standard for enterococci in marine water is a GM of 35/100 ml, assuming at
 least 5 samples are collected per week. As  shown in Table 20, neither seawater sample exceeded
 recreational standards for enterococci.  As a general rule, septic drainfield waste will contain a

 higher proportion of fecal coliforms than enterococci, as its bacterial load. This is further
 indication that the fecal contamination seen in the northern sample is a result of a faulty drainfield
 system rather than fresh fecal waste from wildlife.

 Pseudomonasaeruginosais an olrgani^Th^n¥^i6iquitoiis^irrnatufe and is considered all
 opportunistic pathogen that can cause nasopharyngeal and skin infections. For this reason, its
 presence is tested for in swimming pools and water parks. The single sample standard in these
 recreational waters, is  1/100 ml.  At present,  no standard exists for natural bodies of water and the
 applicability of this standard to seawaters is uncertain.  Table 20 demonstrates that if this standard
 is applicable to seawater samples, neither sample exceeds this level.

 In conclusion, the sample of the actual swimming hole (Station #12; Dexter-by-the-Sea; Table 20)
 met recreational standards for swimming waters. However, the sample selected north of the
 swimming hole demonstrated evidence of recent fecal contamination and may be the site of a
 faulty septic system.

 6.3.3  Aquatic Ecosystem Health:  Shellfish Gonadal Histopathology Preliminary Screening
 Bioassay: "Swimming Hole" and North River /Smith Creek Junction

 It is well established in the literature that there has been an increase in the numbers and types of
 tumors in fish and shellfish in the past several decades.  In most cases, the increase in tumors and
 a variety of other pathologic conditions can be correlated with increases in aquatic toxicant levels
 (75),(76),(77). Two recent epidemiologic investigations identified the prevalence of gonadal
 cancers as high as 40 % i'n softshell clams Mya arenaria in Maine (75), and 60 % in hardshell
 clams Mercenaria spp. in Florida (78). A second study of these same geographic regions
 identified human cancer mortality rates due to ovarian cancer as significantly greater than the
 national average (79).  The research and  epidemiologic evidence has shown that the appearance of
 significant numbers of tumors in these clams (and humans) is correlating to increased use of
 herbicides and agrochemicals used in forestry and citrus farming.  Since the softshell clam is a
 good molluscan indicator species, it was  decided that populations indigenous to Willapa Bay
 could be studied in an effort to begin to characterize general "ecosystem health" near the
 Shoalwater Bay Reservation. A histopathological study of softshell clams was examined by
 EPA's National Health  and Environmental Effects Laboratory, Atlantic Ecology Division, at
 Narragansett, Rhode Island. In September of 1995, 24 specimens were collected at the
 "Swimming Hole", located within the Shoalwater Bay Reservation. In addition, 27 specimens
 were obtained from the North River and  Smith Creek junction at the point of entry into Willapa
 Bay.

 No tumor bearing clams were found at either  site.  Based on statistical probability, if the
 prevalence rate of gonadal tumors was greater than 5-6 % for these Willapa Bay populations, one
 would have expected to see at least one tumor- bearing clam.  Therefore, if a disease exists then
 the prevalence rate is not statistically likely to exceed 5-6 % (80). Although this is only a
 preliminary sampling of a molluscan indicator species, the lack of any tumors is supportive of a
 relatively "clean" environment in terms of xenobiotic chemical stressors and ecosystem health.

 6.4 Drinking Water: Household Sampling

 Limited studies of tribal drinking water sources have been conducted in the past as part of water
 resources investigations, for example by Lum (1984) (81), and Ebbert and Payne (1984) (82).  A
 comprehensive study involving all water supplies used by tribal members both on and nearbythe
 reservation, however, has yet to be undertaken.

 6.4.1  Chemistry: Tap Water Screening for Lead and Inorganic Parameters (Tables 14,  15,
 and 16; Appendix C)

 Drinking water station locations are designated by numbers keyed to Figures 4, 5, and 6.  Station
 descriptors are used to designate clusters of samples in different areas at the Reservation as
 follows: "Reservation-West", along SR 105, "Reservation-Center", on SR 105 near the
 intersection with Tokeland Road, "Reservation-East" on Tokeland Road, and "Reservation-  .
 Annex" above SR 105. Sample descriptors are  also used for designating samples obtained from
 the nearby communities of Westport,  Grayland, South Bend, and Ocosta.

 •     Lead

 Results for lead are listed in Tables 14 and 15.  Low concentrations of lead were detected in 22 of
 32 samples (69%) sampled by the "first-pour" technique (Table 14). None of these samples
 contained lead exceeding the action level of 15 ug/1 established by the Safe Drinking Water Act
 (53). The highest lead concentration was 6.28 ug/1, measured in Sample #25, located in the
 "Reservation-East" area. Nine additional samples had "first-pour" lead concentrations ranging
 from 1 to 5 mg/1,  and twelve samples had lead concentrations between 0,5 ug/1 and 1 ug/1.

 Low concentrations of lead were found in only two of the 19 stations sampled after flushing the
 distribution system.  Both of these stations had concentrations between 0.5 ug/1 and 1 ug/1.

 Table 14 shows a comparison of 13 stations which were sampled by both the "first-pour" and the
 "flushed" technique.  The lower "flushed" lead values in this comparison indicate that flushing is
 effective in reducing lead concentrations.  The samples which had lead concentrations greater than
 1 ug/1 in first-pour samples include both on and  off-Reservation systems (see Figures 4-6, Table
 14). In either case, more samples at additional points along the distribution lines are needed to
 determine whether the source of lead is in household pipes or in the distribution systems.

 •     Complete Inorganics (Tables 15 and 16)

 Tables 15 and 16 list results for the complete inorganic analyses conducted at 19 drinking water
 stations.  Figure 9 shows the major cations and anions in a trilinear diagram (after Piper, 1944)
 (83). Inspection of Figure 9 indicates  the main water types are calcium bicarbonate
 and calcium-sodium bicarbonate waters. The pH of samples ranged from 7.0 to 8.8 (Table 16).
 Electrical conductivity ranged from 130 to 360 uS.  Summation of measured analytes indicates
 that dissolved solids range from 60 to  170 mg/1.
Revision 3.0, January 17, 1997                                                    Page: 70 of 89

-------
   The Shoalwater Bay Reservation: A Limited Environmental Assessment,  1994 - 1995
 The lowest dissolved solids for any of the water systems sampled was measured for the South
 Bend sample (Station #44), the only station served by a surface water source. The highest
 dissolved solids sources were the Westport water system sample (Station #47), the private wells
 for a Bay Center business (Station #45), and the Toke Point well (Station #50).  The higher	
 dissolved solids at the Westport and Toke Point samples is accompanied by somewhat elevated
 sodium and boron, indicating a minor but measurable influence of marine water.

 Samples from the main Reservation water system have a relatively more narrow pH range of 7.7
 to 8.8, with electrical conductivities ranging from 170 to 174 jiS.  Summation of analytes reveals
 a dissolved solids content of 104 to 106 mg/1. In general, the Reservation Annex samples are
 similar in proportions of major ions but somewhat higher in dissolved solids (about 118 mg/1).

 No exceedances of primary drinking water standards, other than total coliforms (as discussed in
 the following section on Microbiology), were detected at any of the drinking water stations
 sampled in this survey.

 Secondary drinking water standards, however, were exceeded for manganese at six stations, and
 for iron at five stations, as listed below (Table 17). Secondary drinking water standards have
 been developed for aesthetic purposes such as staining, taste and color.  The secondary drinking
 water standards for manganese and iron are 50 jig/1 and 300 jig/1, respectively (53).

 Of those samples that exceeded secondary standards for manganese or iron, two were located at
 the main Reservation (Station #48) and Toke Point (Station #50) wellheads, and two (Stations
 #38 and #39) were at the annex buildings. The remaining three exceedances were found at off-
 Reservation stations served by private wells (see Table 15). These were Stations #41 and #42 at
 Ocosta, and Station # 45 at Bay Center.  The highest iron concentration (4930 jig/1) was found at
 the main Reservation well;  Station #48. Since concentrations at all  residence taps sampled on the
 main Reservation distribution system were less than 22 jig/1, the water treatment used for the
 Reservation system appears to effectively remove iron prior to distribution.

 6.4.2  Microbiology: Source Water Screening for Microbiological Contaminants from
 Leaking Septic Systems  (Figures 4-6, Tables 17 and 19)

 As shown in Table 4, drinking water from each home or building sampled in October 1995, for
 lead and inorganic parameters was also sampled for microbiological contaminants. However,
 unlike the previously discussed samples collected for analysis of lead and other inorganics, which
 were always taken directly from an inside user tap at each station, samples collected for
 microbiological testing were preferentially taken at an outside source at each house or building.
 This is routinely done to avoid the possibility of microbiological contamination by human
 activities near, for example, a kitchen, bathroom, or laundry faucet.  Unfortunately, Sample
 Stations # 34 and #42 lacked an outside source, making it necessary to collect microbiological
 samples at these two locations from indoor taps.

 As shown in Figure 6, three wells provide drinking water to the homes / buildings located on the
 Shoalwater Bay Indian Reservation. Well #2, treated by chlorination, provides water to the
 majority of the homes on the reservation  The other two wells provide water to only one or two
 homes /buildings and are apparently untreated.

Revision 3.0, January 17, 1997                                                     Page: 71 of 89

-------
  The Shoalwater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
 To our knowledge no prior studies have been conducted on possible microbiological
 contamination of drinking water systems at the level of individual households or buildings in the
 Shoalwater Bay area.  However, in 1993 EPA Region 10 did collect and analyze drinking water
 samples from the Shoalwater Bay Indian Reservation Well #2, and performed microbiological
 analyses for total /fecal coliforms, HPC, w\^GiardiaTll^ryptosp6ri3.ium. These samples were
 collected from the well prior to chlorination (9),(10),(11). The samples were negative for all
 routinely sought chemical and microbiological analytes at that time.  Since the 1993 sampling, it
 has been reported that all distribution lines supplying buildings from this well have been replaced.

 In this study of individual households/buildings in the area, a total of 38 bacteriological samples
 (including two transfer/transport blanks) were collected from 36 stations both on and off the
 Shoalwater Bay Indian Reservation. All but two (Station #34 and Station #42) were taken from
 appropriate outside sources at each station. Locations of the drinking water microbiological
 samples, obtained from the Shoalwater Bay area on October 23 and 24, 1995, are shown in
 Figures 4-6.  Microbiological results are shown in Table 18.

 None of the drinking water samples tested positive for fecal coliforms (Table 18).  However, five
 samples were  found positive for total coliforms. These were Samples #31(1 colony forming unit
 (CPU) 7100 ml, #34 (1/100 ml), #35 (1/100 ml), #36 (3/100 ml), and #42 (1/100 ml). Three of
 the positive samples (#31, #35, and #36) were located on the Shoalwater Bay Reservation.
 Sample #34 was taken from a private residence in Grayland, and Sample #42 came from a private
 residence in Ocosta (Figure 5).

 Because of the positive results on the initial sampling, these five positive stations were sampled
 again three months later,  on January 22, 1996.  Again, no sample was found positive for fecal
 coliforms.  In this resampling effort,  Sample #35 no longer showed any evidence of total
 coliforms.  However, the remaining four stations still showed positive levels for total coliforms.
 These were: Sample #31 (1 sample out of four was positive; 2/100 ml); Sample #34 (4 samples
 out of four positive; 1/100 ml); Sample #36 (1 sample out of 4 positive, 1/100 ml); and Sample
 #42 (1 sample out of 4 positive, 1/100 ml).

 Sample #31 was the only home supplied by Well #2 (chlorinated) which tested positive for total
 coliforms (1/100 ml) at the initial sampling in October; see Table 18)).  When resampled in
 January, 1995, one of four repeat samples of the Station #31 household again tested positive for
 total coliforms, as described above. Although a "trace" (<0.1 mg/l) of free chlorine was detected
 in Sample #31, this home is apparently  located at the end of the distribution system.
 Consequently, it appears likely that the design of the treatment system may be unable to maintain
 an adequate level of disinfection at this point in the distribution system. Ideally, most chlorinated
 systems should be designed to maintain at least a 0.2 mg/l residual of free chlorine throughout the
 system.

 The remaining two initially total coliform positive samples on Shoalwater Bay property consisted
 of two buildings, identified as Sample Stations #35 and #36 (Table 18, Figure 6), which are
 supplied by a single, separate well. This source appears to be unchlorinated, since chlorine
 residuals from  both buildings were not detected (<0.1 mg/l). Both collection stations tested
 positive at initial sampling for total coliforms at low levels but were negative for fecal coliforms

 and E. coli.  Repeat sampling in January from both of these locations confirmed that bacterial
 contamination was still present at Sample Station #36 but not at Station #35.

 Eight of the thirty six collection stations were located off the Reservation; in various of the
 neighboring^reas^f Westport^ Grayland~ Ocosfa, and SbuthTBehdT  Of these, two tested positive^
 for total coliforms, in both the initial sampling and the repeat sampling three months later.  Sample
 #34 was a residence in Grayland which receives water from the Grayland water utility.  Sample
 #42 was a residence in Ocosta which receives water from a private well.  Neither station had
 detectable chlorine residuals, or an outside sampling point.  As discussed previously, respective
 samples for microbiology were thus necessarily collected from the laundry room sink faucet (for
 Sample #34; Grayland) and from the bathroom sink faucet (for Sample # 42; Ocosta).   Since
 indoor faucets and sinks are often contaminated by various indoor human activities, sampling
 from these locations is discouraged unless no other outside sources can be found.  It thus would
 appear highly likely that the total coliforms contamination found at both stations, at both initial
 and repeat sampling times, is a direct consequence of having to obtain both samples from an
 indoor tap.

          Chapter 7.0  CONCLUSIONS AND RECOMMENDATIONS
 7.1 CONCLUSIONS

 EPA's examination of four major environmental exposure pathways in the vicinity of the
 Shoalwater Bay Tribe, utilizing relatively few samples, can not provide absolute answers about
 whether environmental contaminants are in fact contributing to the recently documented Tribal
 health problems. However, evidence generated by the present study would make this possibility
 seem quite unlikely.

 Two other important environmental exposure pathways for the Shoalwater Bay area, air and
 ground water, were not examined in this report. For reasons described below, their possible
 impacts on the Willapa ecosystem should be explored further.

 Conclusions from this investigation of the four exposure pathways can be summarized as follows:

 7.1.1 Dump Site

 From the results of this preliminary screening investigation, it does not appear that the waste
 stream from the abandoned dump site near the Shoalwater Bay Indian Reservation poses a
 significant health or environmental risk.

 7.1.2 Tideflats

 The limited data from this study show the Willapa sediment samples to be relatively clean and well
 within normal background for contaminants normally associated with such areas.  However,
 certain tideflats-related contaminant issues merit further consideration:

 •      Mercury and Methyl mercury

 Methyl mercury is the most important form of mercury in terms of toxicity, especially to the fetus
 of mothers exposed to methyl mercury during pregnancy (68). In the aquatic environment,
 virtually any mercurial compound may be changed to methyl mercury by microbial activity (84).
 Accordingly, it is also the mercury species of special concern in any aquatic ecosystem where
 disposal of mercury wastes has occurred.

 In this study, the laboratory techniques utilized could not detect methylmercury and other
 organomercury compounds in the sediment samples at sufficiently low levels to draw direct
 conclusions about their presence or effect.  However, the average concentration of total mercury
 in the earth's crust is estimated by Jonasson (1970) at 0.080 mg/kg (85).  For all seven tideflat
 sediment samples, our analytical capabilities for detecting total mercury were in all cases at least
 0.05 mg/kg (50 ug/kg; 50 ppb) or lower.  In two samples, the levels for total mercury were
 higher, resulting in the two  positive measurements of 0.0222 mg/kg (Sample #12A; Table 11) and


Revision 3.0, January 17,1997                                                    Page: 75 of 89

 0.0445 mg/kg (Sample #23). Although we could not specifically measure methyl mercury in this
 study, the relatively low levels for total mercury in the two positive sediments, plus our generally
 low MDLs for total mercury in the remaining sediments provide very strong assurance that methyl
 mercury is not a likely problem in this immediate ecosystem.

 •      Novel Halogenated Compounds in Sediment

 The presence of the bromo- and iodo- compounds with instrumental responses identical to
 bromoxynil and ioxynil at relatively uniform levels throughout the estuary was unanticipated but
 not particularly surprising. Seawater contains a multitude of bromo- and iodo- compounds
 (54),(55). However, the presence of these compounds in the dump drainage was unexpected.
 From the evidence at hand, it appears that these two materials are marine natural products. It is
 unlikely that they represent xenobiotic compounds, hazardous waste, or similar materials
 intentionally added to the Willapa Bay ecosystem. However, because they were found in the dump
 site sediment and because the structure of these compounds appears to be very similar to two
 herbicide compounds, further research is needed to identify and characterize them.

 •      Carbaryl and Glyphosate

 Carbaryl and glyphosate are sprayed on the tideflats to (respectively) eradicate ghost shrimp and
 Spartina sea grass. Carbaryl is not a persistent pesticide, and is degraded via both photolysis and
 microbial activity in sediments and water, especially under conditions of basic pH (86),(87),(88).
 However, until breakdown occurs and flushing and other natural processes can replenish the
 normal intertidal fauna, the spraying is acutely lethal to virtually all invertebrates, nekton and
 plankton living in or passing through the immediate spray zones. This  includes crab zoea, larval
 fishes, and other critical life stages of various key resources in the Bay.  Although much less
 acutely toxic to nontarget species than carbaryl, glyphosate is often used in concert with various
 surfactants, which have high aquatic toxicities. While neither of these compounds was detected in
 the sediment samples collected for this study, the timing of field sampling events precluded the
 collection of tideflat samples at appropriate timeframes immediately following  any scheduled
 chemical application episodes.

 7.1.3  Cranberry Bog Drainage

 This exposure pathway is an obvious problem within the general Willapa Bay ecosystem. Several
 pesticide residues detected in the runoff from this area are sufficiently high to be  in violation of
 federal and state water quality standards.  The theoretical risk from such organophosphates as
 azinphos-methyl is considerable, not only to nontarget organisms but possibly to humans or
 animals who might swim in the ditch, or drink surface water in the immediate area during periods
 of application in the upstream bogs.  Residues of the less toxic but more persistent
 organophosphate, chlorpyrifos, are also an apparent problem in the pesticide drainage ditch.
 Exposure of organisms to mixtures of various pesticide residues in the runoff is also an issue
 which merits further assessment.

 Pesticide runoff from fanning areas raises other concerns beyond the scope of this study such as
 contaminated sediment fate and transport, the long term impact of pesticide laden water runoff

 and sediment deposition on tidelands, and whether vulnerable ground water resources are being
 impacted.

 7.1.4  Drinking Water
 •      Lead

 From the results of this examination of household taps, lead in drinking water is not a problem for
 the Reservation and associated areas at this time. "First-pour" water samples in indoor household
 taps show a slight elevation for lead compared to samples taken after periods of normal flow, a
 typical response for older plumbing systems. However, in no case was a violation of the EPA
 lead action level of 0.015 mg/1 observed.

 •      Organics

 Although the current investigation did not analyze for pesticides and other organics in Tribal
 household drinking water systems, a  1993 EPA analysis of a single sample from the main wellhead
 (EPA, 1993) for organics was unremarkable (9),(10),(11).

 •      Microbiology

 Low levels of total coliforms were found at five of 36 stations.  Of the five stations found positive
 for total coliforms, three were on the Shoalwater Bay Reservation, one was in the neighboring
 Ocosta area, and one was in Grayland. The presence of consistently low numbers of total
 coliforms, in the absence of fecal coliforms, indicates an outside contamination source, either in
 the distribution system or the wellhead. The lack of fecal coliforms indicates that the source of
 contamination is not from fresh fecal  contamination, but may be from soil contamination entering
 the distribution system of the well through infiltration or fractures.  All five stations also had trace
 or no detectable levels of chlorine.  Based on the chlorine and coliform test results, the
 Reservation-West  and Dexter areas have insufficient chlorination to treat the bacteria in the
 systems.

 Station #34 (Grayland) was repeatedly positive for total coliforms (4/4; Table 18). If follow up
 drinking water samples from this suspect station continue to show positive total coliforms, with
 negative results from other  stations in the distribution system, then it is likely that the
 contamination is the result of a domestic or other non-distribution system plumbing problem.

 7.1.5  Livestock Dipping Station

 Preliminary analyses by the  EPA Region 10 Superfund program, of ground water underlying the
 former livestock dipping station appear unremarkable (58), (59), in spite of the chemical
 contamination in the overlying soil. However,  additional testing of ground water, for a greater
 variety of residues and at lower detection levels, is clearly warranted.

 Soil exceedances of EPA risk-based concentrations for several persistent organochlorine
 pesticides were noted for the former dip site, in seven of the various soil samples ranging from the
 surface down to a depth of six feet. Therefore, the EPA Region 10 Superfund Technical

 Assessment and Response Team has recommended a removal action for the contaminated site.
 Based on currently available information, this would involve the removal of approximately 555
 cubic yards of pesticide-contaminated soils, 2000 gallons of pesticide-contaminated water inside
 the cattle dipping tank, and the potentially pesticide-contaminated debris  associated with the

 7.2 RECOMMENDATIONS FOR FUTURE RESEARCH

 It should be emphasized that the various environmental exposure pathways at Willapa Bay impact
 not just the Shoalwater Bay Indian Tribe, but the entire Willapa Bay ecosystem. It is important
 that this ecosystenTbeTecognized and treated as arcomplex and unique area, rich in natural	
 resources but beset with increasing conflict about land use planning and natural resource
 utilization.

 The movement or drift of pesticides beyond the boundaries of the targeted application, is a
 universal concern in areas where competing land use practices and natural resource utilization
 frequently intersect. It is an issue of central importance to the highly productive Willapa Bay
 ecosystem, where pesticides are applied not only to surface water and to soil, but also via aircraft
 to selected tidelands.

 In this limited assessment, two important exposure pathways, Air and Ground Water, were not
 examined. Because of the nature of the Shoalwater Bay - Willapa Bay ecosystem and the
 likelihood of transboundary migration of xenobiotic contaminants into these two environmental
 media, both pathways should receive further scrutiny.

 With these general issues in mind, EPA suggests the following areas for future environmental
 research:

 •     Ground Water

       •    Vulnerable ground water resources underlying areas of application and pesticide
              runoff from cranberry bogs should be screened for pesticides and organics.

 •     Air

       Air is a Shoalwater-Willapa exposure pathway that has not been explored. For most of
       the year, the airshed over Willapa Bay appears to be relatively pristine, free from major
       inversions and urban pollutant sources.  Although the Reservation and surrounding areas
       are very rural, spraying in the tideflats, cranberry fields and possibly locations near the
       Reservation may be creating some exposures.

       Inhalation Exposures: A lingering and complex issue for the Shoalwater Bay area and
       other parts of greater Willapa Bay is the aerial spraying of carbaryl on adjacent tidelands
       during  summer months, to facilitate the commercial propagation of shellfish. The
       inhalation exposure to Tribal members and other residents of living around the Bay during
       pesticide/herbicide application events is unknown.

       •     Some limited air monitoring of likely worse-case areas is recommended during
              aerial pesticide application events.

Revision 3.0, January 17, 1997                                                     Page: 79of 89

-------

        The air pathway not only poses the risk of episodes of acute inhalation and dermal
        exposure of humans, birds and other terrestrial life to ambient concentrations of carbaryl in
        the area, but it also interfaces directly with the intertidal zone, the prime target of the
        spraying.

        •    We recommend further studies of the long term ecological impact of carbaryl on
              nontarget aquatic organisms in the area.

        •    To break the pattern of persistent stressing of micro communities within the
              estuary, State and federal agencies and extension scientists should work with
              shellfish farmers to develop less draconian methods of controlling mud shrimp
              populations.

 »      Tideflats

        Novel Halogenated Compounds (sediment): Because the unusual bromo- and iodo-
        compounds were found in the dump site sediments outside the immediate influence of the
        marine environment and because they so closely resemble two known herbicides,
        additional investigation would allow a better understanding of the source, fate and impact
        of these compounds.

        •    It is strongly recommended that further research be directed to the occurrence of
              these novel compounds, to elucidate their structures, sources, function and
              potential impact.

       Methyl mercury (sediment): Total mercury results were not elevated above background in
       any of the seven sediment samples, suggesting that highly toxic organomercurials are not
       an issue of concern in the general Shoalwater Bay marine ecosystem. However, SQLs for
       methyl mercury were insufficient to obtain specific information about levels of this toxic
       compound.

       •     To more fully augment and strengthen the database for organomercury compounds
              in Bay sediment for this area, additional Willapa Bay sediment samples should be
              obtained and analyzed for organomercury.
       Carbaryl and Glyphosate (sediment /biota):

       •     Sediment samples should be collected reasonably adjacent to the application areas
              immediately after spraying to determine if short-term sediment loading is
              occurring.

       •     The general use of such intentionally applied pesticides in the Willapa ecosystem,
              should be examined closely for possible nontarget effects (see Air).

•      Cranberry Bog Pesticides


Revision 3.0, January 17, 1997                                                     Page: 80of89

-------
  The Shoalwater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
        Pesticide Fate and Transport Via Sediment: Data from only two sampling stations did not
        provide enough information to assess the loading of pesticides in sediment, and where the
        sediment goes.

       ^/     A^h^Te^SensiveTtudy of "tfieatitire~cfanbefry Drainage is necessary to determine
               the extent of sediment contamination and the destination of contaminated
               sediment.
        Aquatic Bioassays:

        •     In-stream monitoring, especially via aquatic bioassays, should be performed to
               determine the cumulative effects of the use of different pesticides and herbicides in
               the cranberry growing area.

        Tissue: While sediment and water residue chemistry did not suggest major problems, no
        tissue samples were collected for the purpose of determining tissue loading or
        bioconcentration of the chemicals of concern.

        •     Inasmuch as bioconcentration mechanisms are not fully understood, selective
               analysis of some sustenance organisms, particularly those impacted by the
               exposure to cranberry runoff, might be revealing.

        Livestock Dipping Station

        Because of the urgent need for new Tribal housing on the Reservation, it is strongly
 recommended that EPA Superfund proceed swiftly to ensure that the proposed soil removal and
 remediation at the former livestock dipping site take place as soon as possible.  This process
 should also include appropriate human health risk and exposure assessments following the
 cleanup, to ensure that the site is suitable for public housing, particularly for occupancy by
 children, pregnant women and similar high-risk groups.

 7.3 RECOMMENDATIONS FOR FUTURE MANAGEMENT PRACTICES AND
 TECHNICAL INVESTIGATIONS
        Drinking Water

        Lead: The data indicate that flushing household taps prior to using the water for drinking
        or cooking is an effective method to reduce lead concentrations.

        •    Educational efforts should be undertaken to encourage this practice.

        Microbiology:  Since the EPA Total Coliform Rule is based on a presence /absence
        concept, a drinking water system positive for coliforms remains in non-compliance
        regardless of the numbers of coliform present. Continued monitoring of microbiological
        contaminants should probably be performed in certain areas.

        •    Assuming that the two off-Reservation (#34 and #42) stations were total coliforms
              positive due to the poor collection points (circumstances necessitating the
              collection of samples from taps inside the home, rather than outside), these homes
              should be further studied to insure positive results were the consequence of a poor
              collection point and not because of contaminated drinking water. The three
              Reservation collection points (Stations #31, #35, and #36) that tested positive at
              outside taps are of more concern.

        •    It is recommended that the Grayland total coliforms positive station located off SR
              105 (Sample #34) be incorporated into the local utility's monthly drinking water
              monitoring program.

        •    Further evaluation of the private well located in Ocosta (Sample #42) should
              include additional testing. If additional samples collected at various points
              throughout this private system continue to be positive for total coliforms, an on-
              site evaluation of the system starting at the well head and storage tank should be
              performed.

        •     If future ground water contamination by pesticides is indicated or predicted by
              future studies, it is recommended that a program of episodic testing of main
              drinking water wellhead(s) for organics and pesticide residues be implemented.

        Tideflats

        Tideflats Microbiology (shellfish/seawater): Fecal contamination in nearshore seawater
        may be indicative of failing septic systems in the area.  Fecal contamination was noted in
       the station selected north of the swimming hole. While not violating any health based
        standards, elevated levels of both E. coli and fecal coliform were also found in razor
       clams. Eating food taken from or swimming in water contaminated with E. coli or fecal
       material could cause serious illness.
Revision 3.0, January 17, 1997                ,                                     Page: 82 of89

-------
   The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995
               The septic systems in affected areas should be evaluated further using a dye-tracing
               method accompanied by concurrent fecal coliforms sampling (89). Those systems
               suspected of failure should be repaired or replaced.
               registered shellfish beds, a single sampling point is insufficient to determine the
               quality of overlying water or shellfish. Further testing of the overlying seawaters
               and shellfish is required to more fully evaluate the microbial safety of the shellfish.

        Cranberry Bog Pesticides

        Best Management Practices (BMPs):

        •     BMPs should be developed which limit and minimize the use of highly toxic, broad
               spectrum pesticides such as guthion and chlorpyrifos.

        •     Agencies responsible for pesticide registration (USEPA,. Washington State
               Department of Agriculture) should work closely with appropriate federal, state and
               local water quality agencies (Washington State Department of Ecology (WDOE),
               EPA ORD, wetland researchers, etc.), and with growers and other appropriate
               parties, in revising and improving the process of selecting pesticides to be used in
               this complex aquatic ecosystem.

   Appendix F:  DATA QUALIFIERS USED TO VALIDATE ORGANICS
                                         DATA
The following qualifiers were used for organics measurement data attached to this Report:

       U  - The analyte was analyzed for, but was not detected above the sample quantitation
             limit.  The associated numerical value is based upon the lowest calibration point of
             the 5-point initial calibration curve and any dilutions which were made to the
             sample due to high concentrations or matrix effects.

             If a decision requires quantitation of the analyte below the associated numerical
             level, reanalysis or alternative analytical methods should be considered. The
             technical staff is available to discuss available options.

       J - The  analyte was analyzed for and was positively identified, but the associated
             numerical value may not be consistent with the amount actually present in the
             environmental sample. The data should be seriously considered for decision
             making and are useable for many purposes.

             A subscript may be appended to  the "J" that indicates which of the following
             quality control criteria were not met:

                    1 Blank Contamination:  indicates possible high bias and/or false positives.

                    2 Calibration range exceeded: indicates possible low bias.

                    3 Holding times not met: indicates low bias for most analytes with the
                    exception of common laboratory contaminants and chlorinated ethenes (i.e.
                    trichloroethene, 1,1-dichloroethene, vinyl chloride).

                     4 Other QC outside control limits: bias not readily determined.

      R - The sample results are rejected due to serious deficiencies in the ability to analyze the
             sample and meet quality control criteria.  The presence or absence of the analyte
             cannot be verified.

             Resampling and reanalysis are necessary to confirm or deny the presence of
             the analyte.

      UJ - The analyte was analyzed for and was not detected above the reported  quantitation
             limit.  However, the reported quantitation limit is approximate and may or may not
             represent the actual limit of quantitation necessary to accurately and  precisely
             measure the analyte in this sample.

             If a decision requires quantitation of the analyte close to the associated numerical
             level, reanalysis or alternative analytical methods should be considered.

-------
The Shoahvater Bay Reservation: A Limited Environmental Assessment, 1994 - 1995	


     N - The analysis indicates the presence of an analyte for which there is presumptive
             evidence to make a tentative identification.

             Confirmation of the analyte requires forther analysis:	
     NJ - A combination of the "N" and the "J" qualifier. The analysis indicates the presence of
            an analyte that has been "tentatively identified" and the associated numerical value
            represents its approximate concentration.

            A subscript may be appended to the "NJ" that indicates which of the following
            situations applies:

                   1 DDT/Endrin breakdown evident.

                   2 Interference from other sample components.

                   3 Non-Target Compound List (TCL) organic compounds  (Confirmation is
                   necessary using specific target compound methodology to  accurately
                   determine the concentration and identity of the detected compounds.)

                   4 A confirmation analysis was missing or quality control criteria were not
                   met for the confirmation analysis.

     NAF - Not analyzed for.

     NAR - No analytical result.

     * - The analyte was present in the sample. This is a visual aid to locate detected
     compounds on the report sheet.

-------
        Appendix G: DATA QUALIFIERS USED TO VALIDATE
                            INORGANICS DATA
 The following qualifiers were used for inorganics measurement data attached to this
 Report:

 U - Element was analyzed but not detected.  The associated numerical value is the
       method detection limit, as defined in 40 CFR Part 136, Appendix B.

 P - The analyte was detected above the Instrument Detection Limit, but not quantified
       within the expected limits of precision.  The laboratory has established minimum
       quantitation limits having a relative standard deviation of no more than 10%.

 H - The samples were analyzed after the suggested holding time limit.

 E - The reported value is an estimate because of the presence of an interference.  An
       explanatory note is provide in the data validation report.

 B - Analyte is found in the analytical blank as well as the sample indicating
       possible/probable blank contamination.  If analytes are found in any of the
       associated procedural blanks the concentration in the samples must be at least ten
       times the quantity observed in the blank. If the sample result fails these criteria the
       sample result is qualified (B).

 N - Spiked sample recovery not within control limits.

 NAR - There is no analysis result for this sample.

 S - Sample was analyzed by method of standard additions.

 + - Sample was analyzed by method of standard additions and the correlation coefficient
       was less than 0.995.

 * - The analyte was present in the sample.

W - Post spike out of specified range, and sample was less than 50% the spike added.
