PUBLIC HEALTH ASSESSMENT
ST. JULIENS CREEK ANNEX (U.S. NAVY)
CHESAPEAKE, CHESAPEAKE COUNTY, VIRGINIA
Based on our evaluation of available environmental information, ATSDR concluded that no harmful exposure to chemical contaminants currently exists at St. Juliens Creek Annex. The possibility that buried UXO may exist in the sediments near the wharf poses a safety hazard for people who ignore the posted warning signs. The following paragraphs provide the specific conclusions for each pathway-specific exposure. (Definitions for ATSDR's public health conclusion classifications are provided in Appendix F.)
Exposure to Contaminants in Groundwater. Contaminants were detected in the shallow groundwater and deep groundwater beneath St. Juliens Creek Annex. Both of these aquifers flow to St. Juliens Creek and the Elizabeth River, and this water is not for drinking purposes. The City of Portsmouth provides drinking water to residents of Portsmouth and also to St. Juliens Creek Annex. The City of Chesapeake provides drinking water to the residents of Chesapeake. There is no exposure to contaminants in the shallow or deep groundwater in the vicinity of St. Juliens Creek Annex. Groundwater was classified as no public health hazard.
Exposure to Contaminants in Soil. Contaminants were detected at elevated levels in surface soils from some on-base industrial or disposal locations. ATSDR studied exposure conditions and the toxicity of the contaminants and determined that no harmful exposures currently exist at the detected levels, especially in light of access restrictions to industrial areas, and completed and ongoing cleanup efforts by the Navy. Former on-base housing residents had access to the industrial and disposal areas, but are expected to have had infrequent contact with the soil. Their exposure to soil contaminants would likely have been well below levels known to cause health effects. On-base residents may have had contact with lead in the soil, dust and paint in the housing area. Blood lead data specific for children living on St. Juliens Creek Annex is not available. However, blood lead data for Navy-affiliated children living near Portsmouth, VA, indicates the area children generally had low blood lead levels, were unlikely to have had adverse effects as a result of exposure to these levels of lead, and were likely to have been effectively treated under the Navy's lead prevention program. Past exposure to on-site soil in industrial areas was classified as no apparent public health hazard. Past exposure to lead in the St. Juliens Creek Annex housing was classified as an indeterminate public health hazard. Current exposure at all on-site locations was classified as no public health hazard.
Exposure to Contaminants in Sediment and Surface Water. Some on-base surface water and sediment samples contained elevated contaminants levels. Former on-base housing residents could have come into contact with those contaminants while visiting Blows Creek or on-base marsh areas. ATSDR concluded that people would likely not have had significant contact with these contaminants and the potential exposures would have been below levels of health concern. The on-base housing area has been closed and access to the annex is currently restricted; there are no current exposures to the on-base water bodies. Local residents may have contact with sediment and surface water in St. Juliens Creek and the Elizabeth River during recreational activities. The limited sampling data available for the surface water and sediment near the annex suggests that recreational users will not be exposed to contaminants at levels that are known to cause health effects. Several community groups are studying the Elizabeth River: these groups are expected to issue reports that assess the watershed as a whole. Past contact with on-site surface water and sediment was classified as no apparent public health hazard. Current contact with on-site surface water and sediment was classified as no public health hazard. Contact with off-site sediment and surface water located immediately adjacent to St. Juliens Creek Annex was classified as no apparent public health hazard.
Exposure to Contaminants in Seafood Caught in Blows Creek, St. Juliens Creek, and the Elizabeth River. Virginia prohibits the consumption of shellfish other than crabs (i.e., bivalve mollusks such as clams, oysters, and mussels) from the Elizabeth River and its tributaries, primarily due to the coliform levels (bacteriologic contamination). There are no fishing restrictions for this area. Fish and crabs collected from St. Juliens Creek or the Elizabeth River have the potential to be affected by contaminant sources from this entire area. ATSDR was not able to obtain sufficient fish tissue sampling data from the waterways surrounding St. Juliens Creek Annex to evaluate if health concerns would be expected for consumers of fish from this area. ATSDR recommends that people review and follow advisories issued by EPA and the Virginia Department of Health that indicate how to select and prepare seafood to reduce potential exposures to some types of contaminants. EPA's recommendations are online at http://www.epa.gov/waterscience/fish, which includes a link to Should I Eat the Fish I Catch? A Guide to Healthy Eating of the Fish You Catch, a brochure developed in collaboration with ATSDR. The Virginia Department of Health (VDH) recommendations are at http://www.vdh.state.va.us/hhcontrol/fishing_advisories.htm. Because the specific nature of contamination in fish and shellfish in waterways near St. Juliens Creek Annex are not fully characterized, it is not possible to draw definitive health conclusions; therefore the consumption of locally caught finfish and crabs was classified as an indeterminate public health hazard.
Exposure to Contaminants in Air Emissions. Operations at St. Juliens Creek Annex that may have released contaminants to the air include burning ordnance and municipal waste. ATSDR did not identify any data that quantified the amount of material that was burned or the frequency of the burns, or the actual air emissions. However, the burn locations were all located more than ¼ mile from the nearest housing area and the burns were just periodic operations. ATSDR expects that the concentrations of contaminants released by the burn decreased significantly by the time the smoke cloud would have approached a housing area. Because the burns were a periodic occurrence, people would only have had intermittent contact with the contaminants in the smoke. Given the distance and the periodic nature of the burns, community exposure to the contaminants in the smoke was likely below levels known to cause health effects. All burning operations ceased by the late 1970s. Sampling for volatile compounds at waste disposal areas, the landfill, and burning grounds, conducted in the early 1980s, indicate no emissions from these sites. Due to the lack of past air emissions data, past exposure to air was classified as an indeterminate public health hazard. No current air emission sources at St. Juliens Creek Annex have been identified; therefore, current exposure to air was classified as no public health hazard.
Potential Physical Hazard from Unexploded Ordnance. Many buildings at St. Juliens Creek Annex were used for constructing and packing naval ordnance. The Navy decontaminated those buildings, and determined there is no risk of explosion. While it is not possible to ensure that ordnance is not present on base property, the investigations and cleanup actions conducted by the Navy, and site access restrictions prohibiting public access to the base ensure that the public will not be exposed to UXO on the annex. The former wharf area in the Elizabeth River, however, still contains buried metal debris. Though the Navy has not identified any ordnance in this area, its presence cannot be ruled out. The Navy's Range Program has posted signs along the fence of St. Juliens Creek Annex, that warn boaters to remain away from the area. Boaters can adequately protect themselves by following the posted warnings. There is a small potential for unexploded ordnance to exist in the sediments near the wharf, however boaters and others using this area of the Elizabeth River can protect themselves by following the posted warning signs.
Members of the local community should follow all seafood consumption advisories issued by federal and state agencies, including the prohibition on eating shellfish (except crabs) from the Elizabeth River and its tributaries.
Boaters should follow all signs regarding restricted areas of St. Juliens Creek.
ATSDR recommends that if the Navy and USACE intend to change the land use for St. Juliens Creek Annex, its wharf, or the downstream river bank in the future, additional testing commensurate with the proposed land use be conducted to ensure that UXO concerns are adequately addressed. Specifically, anomalies identified in the sediment near the wharf should be investigated.
The Public Health Action Plan for St. Juliens Creek Annex contains a description of actions taken and to be taken subsequent to the completion of this PHA by ATSDR, EPA, VDEQ, VDH, and the Navy. The purpose of this plan is to ensure that this PHA not only identifies potential and ongoing public health hazards, but also provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment. Completed, ongoing, or planned public health actions are listed below.
In the late 1970s, during the initial assessment of contamination at St. Juliens Creek Annex, the Navy decontaminated multiple areas containing potential explosive hazards and removed 31 inactive buried ordnance items.
The Navy removed contaminated soils and debris from Sites 3, 6, 7, 9, 12, 13, and 14 (Waste Disposal Area C, Small Items Pit, Old Storage Yard, Pesticide Control Shop at Building 249; Sand Blast Area at Building 323; Waste Generation Area; and the Equipment Washrack at Building 266).
The Navy planted grass at IRP sites 1 and 3 (Waste Disposal Areas A and C) to prevent soil erosion.
The Navy covered all housing quarters with metal or vinyl siding in the early 1990s, to reduce exposure to exterior lead paint. After completion of the Lead Management Plan, the Navy cleaned and painted the interiors of all housing quarters, mulched the outside areas, then determined that the quarters should be vacated over time. The quarters were all vacated by 2000 (NEHC 2003a).
The Navy held a meeting in September 1996 to explain the lead conditions of the housing areas to people living there. At this time, the Navy requested that residents not plant gardens. The Navy notified all personnel moving into these quarters of the lead condition and restrictions. These personnel were required to sign a form indicating that they understood these issues (NEHC 2003a).
The Navy demolished multiple housing areas on Annex property during 2001, eliminating the potential hazard to children from lead in soil, dust, and paint.
Under the Navy's Range Program, warning signs were posted to indicate that access to the annex from waterways was unauthorized. A notation was placed in Navy Real Estate documents and a notice was sent to USACE to prevent dredging without proper UXO clearance.
The Navy, EPA and VDH signed a Federal Facilities Agreement in April 2004 to govern the investigation and remediation activities at St. Juliens Creek Annex.
VDH continues to monitor blood lead levels of children in the residential area north of St. Juliens Creek Annex, as part of the state-wide testing program.
As a prudent public health measure, ATSDR encourages parents of children age 6 years old and younger living near St. Juliens Creek Annex undergo blood lead screening, consistent with CDC and VDH Lead-Safe Virginia guidance.
As of 2003, the Navy has recommended further study and/or additional sampling at IRP sites 2, 8, 17, 19, and 21, and at EPIC AOC 1. Feasibility Studies are still in progress for IRP sites 4 and 5.

|Pathway Name||Exposure Pathway Elements||Time of Exposure||Comments|
|Source of Contamination||Environmental Medium||Point of Exposure||Route of Exposure||Exposed Population|
|Eliminated Exposure Pathway|
|Drinking water||Contaminated groundwater beneath industrial areas and landfills.||Groundwater||None||None||None||None||Past/Current/Future: Shallow and deep groundwater flow to the Elizabeth River, St. Juliens Creek, and Blows Creek. There are no groundwater users located downgradient of St. Juliens Creek Annex. Drinking water at St. Juliens Creek Annex and surrounding communities comes from sources far from St. Juliens Creek Annex.|
|Known or Possible Exposure Pathways|
|Surface soil||St. Juliens Creek Annex||Soil||Annex and vicinity||Incidental ingestion, inhalation,
|Workers, visitors, residents||Past||
Past: Past residents of St. Juliens Creek Annex housing areas may have been exposed to contaminants at industrial areas. Most of the soil contamination was located at minimally-accessible industrial areas. Past residents may have been exposed to elevated levels of lead in soil, dust, and paint, at the housing areas, however blood lead testing data suggest that most or all of the children who lived there in the late 1990s did not have an elevated blood lead level, and are unlikely to have had health problems from the lead in their immediate environment.
Current/Future: The housing area was vacated in 2000 and St. Juliens Creek Annex is closed to the public. Site contamination is not transported to areas outside the site by surface water or surface run-off.
|Surface water and sediment||St. Juliens Creek Annex||Surface water||Blows Creek, St. Juliens Creek, and the Elizabeth River||Incidental ingestion, inhalation, dermal contact||On- and off-site residents; recreational users of local waterways (fishers, boaters, swimmers)||
Past: Former residents of St. Juliens Creek Annex could have used Blows Creek for recreational uses. ATSDR expects that young children did not access the industrial areas or the nearby marsh areas. Elevated levels of inorganics and PAHs were found in the creek, but these levels are not expected to have posed a health hazard to any recreational users. ATSDR was unable to identify any records indicating that Blows Creek was used for recreational purposes.
Current/Future: Recreational users have access to St. Juliens Creek and the Elizabeth River for swimming, fishing, and boating, and may be exposed to sediment and surface water. There is no public access to Blows Creek. People have been seen fishing on the Elizabeth River shore opposite St. Juliens Creek Annex, but site access is restricted, so nobody is expected to come in contact with sediments along the Annex side of the river. Sampling of sediment found elevated levels of inorganics, pesticides/PCBs, and SVOCs. Recreational users may contact sediment and surface water incidentally and infrequently. Unexploded ordnance (UXO) is discussed in the Physical Hazards section.
|Fish and shellfish||Various sources||Fish and shellfish||St. Juliens Creek and Elizabeth River||Ingestion||Fishers and their families||
|The extent to which crabs and fish are eaten from St. Juliens Creek and the Elizabeth River is unknown. VDH prohibits consumption of shellfish, based on coliform levels in the water. Other agencies are studying contamination in the Elizabeth River watershed. Fish eaters can best protect themselves by following state and local agencies' advisories for eating seafood, including recommendations about how to select and prepare seafood to reduce potential exposure to contaminants.|
|Air||Burning of trash and ordnance||Air||Annex and vicinity||Inhalation||Workers, visitors, on-base and off-base residents||Past||
Past: Ordnance materials and other trash were burned at landfills and burning grounds from the 1920s until the 1970s, releasing potentially hazardous contaminants to air. Uncontrolled burns were reported multiple times. Off-site housing is within one quarter mile of likely sources of air emissions, and former on-site housing areas are a similar distance of other likely sources. Both areas may have experienced unknown, likely short duration, exposure to air emissions. No sampling of air was conducted during burning to document possible exposure.
Current/Future: Air sampling, from many years after operations ended, detected no VOCs or radionuclides in air at likely emissions sites, meaning no exposure hazard currently exists.
|Physical hazards||St. Juliens Creek Annex||Various||Industrial areas at St. Juliens Creek Annex; soft sediment at the former wharf area in the Elizabeth River.||Contact||On- and off-site residents; recreational users of local waterways||
|Past/Current/Future: Loading/unloading operations at the former wharf area may have dropped ordnance in the water and these items may be present. There are no documented cases of any contact with unexploded ordnance (UXO) on site grounds and there is no access to St. Juliens Creek Annex. The Navy Range Program has posted warning signs to inform boaters not to enter the area that may contain UXO in sediments.|
