PUBLIC HEALTH ASSESSMENT

MARION (BRAGG) DUMP
MARION, GRANT COUNTY, INDIANA


CONCLUSIONS

  1. Currently, there is a public health hazard to individuals who eat fish from the off-site pond. Tissue sampling of fish taken from the off-site pond revealed mercury contamination at levels of health concern. The pond water and sediment poses an indeterminate public health hazard because mercury was present at high levels in the initial sampling but was absent in a subsequent surface water sample.

  2. There is no apparent public health hazard from on-site exposure because 1) access to the site is restricted by a fence surrounding the site, and 2) the site is covered by a clay cap. If the site is converted to a recreational or residential area in the future, on-site workers or residents could be exposed to contaminants in the subsurface soil. Also, if private wells are installed at the site in the future, exposure to groundwater contaminants is possible.

  3. Groundwater in the site area and the Mississinewa River downstream of the site have elevated levels of sodium.

RECOMMENDATIONS

The ISDH Environmental Epidemiology Section has reviewed all available information regarding the site. The following recommendations are made in response to statements made in the Conclusions Section:

  1. Restrict access to the off-site pond until further information is collected through routine monitoring of the pond. In addition, fish from the off-site pond should not be consumed until additional sampling of the fish and pond has been conducted.

  2. Conduct additional sampling of surface water, sediment, and fish in the off-site pond to determine the extent of contamination by mercury or other contaminants of concern.

  3. Continue restriction of access to the site to prevent exposure to contaminants in the soil and on-site pond.

  4. Routinely monitor the Mississinewa River for increased concentrations of sodium and other site-related contaminants.

Health Activities Recommendation Panel (HARP) Recommendations

In accordance with the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 as amended, the data and information developed in the Marion (Bragg) Public Health Assessment have been evaluated by the Health Activities Recommendation Panel (HARP) for appropriate follow-up health actions. The ISDH will continue to provide community health education on site-related health issues. HARP concurred with the ISDH that although it is possible that individuals were previously exposed to on-site contaminants during recreational activities, adverse health effects are unlikely because of the short time period and low levels of exposure. In addition, because these potentially exposed individuals cannot be identified, no other follow-up actions are indicated at this time. If any additional data become available that suggest that human exposure to hazardous substances at levels that could cause illness or injury is occurring, ATSDR and ISDH will reevaluate this site for appropriate follow-up.

PUBLIC HEALTH ACTION

Actions Planned

Based on the recommendations made in the public health assessment, the following public health actions have been or will be undertaken.

  1. ISDH will continue to provide community health education on site-related health issues.

  2. ISDH will work jointly with EPA and the Indiana Department of Environmental Management to accomplish the following:

    • additional sampling of surface water, sediment, and fish in the off-site pond is conducted; and

    • restricting access to the off-site pond until further information is collected through routine monitoring of the pond.

Actions Undertaken

  1. The Mississinewa River is routinely monitored for increased concentrations of sodium and other contaminants.

  2. Access to the site is completely restricted.
