From the MDCH:
Of the results from the Public Health Assessment, soil from the former burn area and from a nearby neighborhood did not have levels of chemicals over health-based screening levels. There are ash piles in the former burn area that do have levels of arsenic and lead over health-based screening levels. However, people are not expected to be harmed by those chemicals, as people will have little to no contact with the ash piles.
Further, shallow groundwater under the former burn area had higher levels of chemicals than groundwater from deeper underground. This could potentially mean that chemicals in the soil or ash piles at the former burn area could be moving into the groundwater. People have little, if any, contact with the shallow groundwater under the former burn area, and nearby private drinking water wells did not have chemical levels above health-based screening levels.
The MDCH officials are inviting comments from the public on their health assessment. Comments are being accepted through May 7.
The Environmental Protection Agency has been developing a cleanup plan for the site and the Velsicol chemical plant site.
