PUBLIC HEALTH ASSESSMENT

WHEELING DISPOSAL SERVICE COMPANY LANDFILL
AMAZONIA, ANDREW COUNTY, MISSOURI


CONCLUSIONS

From the information reviewed, DOH and ATSDR conclude that the Wheeling Disposal site currently poses no apparent public health hazard. No exposures are known to be occurring at this time; although, there is potential for exposures to occur in the future.

  1. Shallow groundwater has been confirmed to be contaminated on site. Contamination of the deeper groundwater has not been confirmed.


  2. Pesticides have been found in the on-site ravine sediments.


  3. Site access is restricted and warning signs are posted, limiting access to on-site contaminants.


  4. On-site contaminants are covered with a geoliner, soil cover and vegetation, limiting exposures.

RECOMMENDATIONS

  1. Monitor off-site and on-site shallow and deep groundwater to determine if contaminants are migrating from the site into groundwater.


  2. Monitor surface water and seeps, including the intermittent streams to determine if contaminants are migrating into surface water.


  3. Monitor vegetation, soil cover and geoliner in waste areas to assure that vegetative cover remains intact.

PUBLIC HEALTH ACTION PLAN

The Public Health Action Plan (PHAP) for the Wheeling Disposal Service Company, Inc., site contains a description of actions to be taken by ATSDR and/or DOH at and in the vicinity of the site subsequent to the completion of this public health assessment. The purpose of the PHAP is to ensure that this public health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment. The public health actions that have been or will be implemented are as follows:

  1. DOH will continue to monitor available private wells around the site as part of their legislatively-mandated responsibilities in monitoring waste sites throughout the state. The wells selected for monitoring will be those identified as most likely to become contaminated and those used for human water supplies.


  2. DOH/ATSDR will review new sampling data as they become available.


  3. DOH will continue to respond to reports and concerns expressed by the community or will refer the concerned person to the agency who can address the concerns.
