PUBLIC HEALTH ASSESSMENT

Bloomington PCB Sites
Bloomington, Monroe County, Indiana
and
Spencer, Owen County, Indiana

CONCLUSIONS

Anderson Road Landfill

Based on the environmental data reviewed, this site is judged as being a past public health hazard to trespassers and scavengers due to levels of PCBs present in the on-site soil.
An indeterminate health hazard is posed by private well use. Two wells northeast of the site are potentially still in use. Private wells in this area have been sampled for PCBs but not other site-related contaminant.
Community-specific health outcome data do not indicate that the site has had an adverse health impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.
Sampling data for methane gas was not found in the data reviewed for this report.

Bennett Stone Quarry

Based on the environmental data reviewed, this site is judged as being a past public health hazard to trespassers, scavengers, subsistence fishermen, and mud bathers due to levels of PCBs that were found in on-site soil and off-site sediment samples.
Fish caught from Stout's Creek pose a present public health hazard if eaten on a regular basis. The levels of PCBs found in fish taken from Stout's Creek are above the FDA recommended level.
An indeterminate health hazard is posed by private well use. These wells are the only source of potable water in this area. Private wells within 5,000 feet have been sampled for PCBs, but no other site-related contaminants.
The INDOT has responded to the EPA, and IDEM's concern about the creation an interchange for S.R. 46 and S.R. 37, which will traverse within 250 feet of this site. The construction of this interchange could pose a public health hazard through the excavation of potentially PCB-contaminated soil. The INDOT has hired an environmental consultant to develop a PCB sampling plan for this project. This plan has been submitted to the IDEM and EPA for review. A report has not been prepared as to the potential human exposure.
Community-specific health outcome data do not indicate that the site has had an adverse impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.

Lemon Lane Landfill

Based on the environmental data reviewed, this site is judged as being a past public health hazard to trespassers and scavengers due to levels of PCBs that were found in on-site soil.
There is a past indeterminate health hazard posed by past private well use. All residences have been connected to the municipal water supply. Private wells within 5,000 feet have been sampled for PCBs. Sampling data for other site-related contaminants such as TCE and dioxins were not found.
High levels of PCBs were found in the wooded depressions near this site. Data are not available as to whether actions have been taken to ensure that humans are not exposed to significant concentrations of PCBs found in this area.
Community-specific health outcome data do not indicate that the site has had an adverse impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.
High levels of PCBs were found in the associated springs and streams for this site and may pose a health risk to individuals who came into contact with them primarily through dermal contact.
There is a data gap concerning dioxins and furans in the site-associated springs and streams.

Neal's Dump

Based on the environmental data reviewed, this site is judged as being a past public health hazard to trespassers and scavengers due to levels of PCBs that were found in on-site soil.
An indeterminate health hazard is posed by private well use. Samples from private wells within 5,000 feet were all below the detection limit. Due to the on-site groundwater contamination, there is the potential for private wells to be contaminated.
High levels of PCBs were found in a ditch leaving (south-southwest) Neal's Dump. Data are not available as to whether actions have been taken to ensure that humans are not exposed to significant concentrations of PCBs found in this area.
Community-specific health outcome data do not indicate that the site has had an adverse impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.

Neal's Landfill

Based on the environmental data reviewed, this site is judged as being a past public health hazard to trespassers, scavengers, and subsistence fishermen due to levels of PCBs found in on-site soil and off-site sediment samples.
This site was a public health hazard to individuals who ate more than one meal per week of fish caught in Richland Creek or Conard's Branch. The levels of PCBs found in fish taken from Richland Creek are currently below the FDA recommended level.
There is one private well connected hydrogeologically to the site. Although PCBs were found at very low levels, the on-site groundwater contamination presents a potential for this well to become contaminated.
The current National Pollutant Discharge Elimination System permit level may not be protective of human health and the environment.
The current collection and treatment systems may not be protective of health during high water flow conditions, thus presenting the potential for recontamination of Richland Creek.
Cattle drinking from Conard's Branch may become contaminated with PCBs due to the problems identified in conclusions 4 and 5 listed above. This would pose a public health hazard to individuals consuming these cattle.
Community-specific health outcome data do not indicate that the site has had an adverse impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.

Winston-Thomas Facility

Based on the environmental data reviewed, this site is judged as being a past and present public health hazard to individuals who used sewage sludge for gardening purposes and subsistence fishermen due to levels of PCBs that were found in sewage sludge, and off-site sediment samples.
An indeterminate health hazard is posed by private well use. Samples from private wells within 5,000 feet were all below the detection limit of 98 ppt. Due to the on-site groundwater contamination, there is a potential for private wells to become contaminated.
The sediment and surface water of Clear Creek are contaminated with PCBs at levels of health concern. The levels of PCBs found in fish taken from Clear Creek are above the FDA recommended level.
Community-specific health outcome data do not indicate that the site has had an adverse impact on human health. Elevated PCB body burdens were found in specific sub-groups from the Bloomington area, i.e.; scavengers and fish eaters. These sub-groups may be exhibiting signs and symptoms of adverse health outcome due to site-related exposures that would not be identified through analysis of county-wide databases.

All Sites

Due to the number of sites and parties involved in sampling occurring over such a long period of time, it is possible that pertinent environmental data may have been inadvertently left out of this document.
Existing ATSDR toxicological profiles for aluminum, boron, chloroethane, cobalt, heptachlor, lead, 1,1,1,-trichloroethane, vanadium, and zinc lack a MRL, which would allow a better assessment of the site's public health implication. There is a need for a toxicological profile for sodium.
Physicians may lack information regarding the toxicity of exposure to PCBs.
Significant exposures may have occurred at sites of former scavenger activities and where PCB-contaminated sewage sludge was used in private gardens.

RECOMMENDATIONS

Site-specific recommendations:

Anderson Road Landfill

Periodic sampling of MW-1 and MW-6 should be performed to ensure that humans are not exposed to significant concentrations of site-related substances.
Soil gas sampling for methane gas needs to be done.

Bennett Stone Quarry

The Fish Advisory for Stout's Creek should be continued.
Periodic private well sampling should be performed to ensure that humans are not exposed to significant concentrations of hazardous substances in the future. A well survey should be done for the area due to the unknown number of private wells still in use.
Communications should be maintained with the INDOT to ensure that the potential health risk involved in creating the interchange across potentially contaminated soils is addressed appropriately. Close attention should be given to groundwater contamination as well as contamination of environmental media with other chemicals.

Lemon Lane Landfill

Individuals using private wells for any purpose should have their well tested for PCBs and other site-related contaminants such as TCE and dioxin.
Information should be obtained regarding private well sampling for other chemicals besides PCBs.
Additional information should be obtained concerning the PCB-contaminated wooded depression area as to whether remediation has occurred in a manner protective of public health.
Actions should be implemented to prevent human exposures to the contaminated streams and springs associated with this site.
To reduce the potential for incidental ingestion and dermal exposures, children should not be allowed to play around and in the streams and springs associated with this site. Any persons performing activities in and around these areas should wash all exposed parts of the body as soon as possible.
Fill the data gap concerning dioxins and furans in the springs and streams associated with this site.

Neal's Dump

Periodic private well sampling should be performed to ensure that humans are not exposed to significant concentrations of hazardous substances in the future.
Additional information should be obtained concerning the documented contaminated ditch as to whether remediation has occurred in a manner protective of public health.
Actions should be implemented to prevent human exposures to the ditch until the data gap in number two is obtained.

Neal's Landfill

Periodic sampling should be performed on all private wells to ensure that humans are not exposed to significant concentrations of hazardous substances in the future.
A re-evaluation of the water collection and treatment system should be made to ensure that the NPDES permit level for this site is at a level which will not result in the accumulation of PCBs in aquatic species, wildlife, and domestic animals, and is also protective of public health.
Additional sediment sampling should be performed at Richland Creek and Conard's Branch to ensure that PCB recontamination is not occurring.

Winston-Thomas Facility

Periodic sampling should be performed at the private wells within 5,000 feet of the site to ensure that humans are not exposed to significant concentrations of hazardous substances in the future.
The Fish Advisory should be continued for Clear Creek.
All vegetables grown in sludge-treated gardens must be washed thoroughly and peeled before eating.
Actions should be implemented to prevent human exposures to the contaminated sediment and surface water found in Clear Creek.

All Sites

When indicated by public health needs, and as resources permit, the evaluation of additional relevant environmental data, health outcome data, and community health concerns, if available, is recommended.
It is also recommended that substance-specific applied research be conducted to identify a chronic MRL for ingestion exposure to aluminum, boron, chloroethane, cobalt, heptachlor, lead, 1,1,1,-trichloroethene, vanadium, and zinc. In addition, a toxicological profile should be written for sodium.
Community health education programs should be developed and implemented for local nurses and primary care physicians.
State and Federal environmental agencies should perform surface soil analysis for PCBs at sites where scavenging activities were known to occur, as well as at sites where PCB-contaminated sewage sludge was thought to have been used.
A full characterization of the sewage sludge taken from the Winston-Thomas Sewage Treatment Plant is needed so that calculations can be made of the potential health impact of using sludge in vegetable gardens.

Studies

The following types of studies are recommended to further evaluate the impact of PCB contamination on human health.

Since little information is available regarding the specific congeners present and the half-life of PCBs in human serum, it is recommended that a study of individuals in the Bloomington area who have previously had their blood tested for PCBs be used in a congener-specific serum PCB study.
Workers at the Westinghouse/ABB plant may currently be exposed to PCBs. Additional studies of the PCB levels present in the plant, and their effect on the health of the workers, may be warranted.
Former workers have expressed concerns that their health has deteriorated. Re-evaluation of these workers by NIOSH and the ISDH should be performed using the same methods as were used in earlier investigations so that changes in the signs or symptoms of disease can be determined.
