Reassessment of Soil and Groundwater, Atlantic Water Supply Superfund Site, Atlantic, Cass County, Iowa
The U.S. Environmental Protection Agency (EPA) Region 7 will oversee a site reassessment of soil and groundwater sampling at the Atlantic Water Supply Site in Atlantic, Cass County, Iowa. This sampling is scheduled to begin during the first week of October 2012. The soil and groundwater sampling is being conducted under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) or Superfund Program site assessment process. Site assessments are typically conducted to determine if contamination exists at levels that are harmful to human health and the environment.
Atlantic, Iowa, is a rural community in northeastern Cass County, about 75 miles west of Des Moines, Iowa, and 45 miles northeast of Council Bluffs, Iowa.
The municipal water supply well field in Atlantic, Iowa, has been impacted by perchloroethylene (PCE). The source of the contamination is believed to be a former dry cleaners facility. Norge Dry Cleaning Village operated at this location during the 1960s.
Based on historical data, the building that housed the former dry cleaners was demolished between 1982 and 1994. The location is now owned by the Rolling Hills Bank and Trust.
The Iowa Department of Natural Resources has monitored the site for several years to ensure that PCE contamination was below action levels. EPA is reassessing the area to also ensure that contamination levels at the site are protective of human health and the environment.
This site reassessment is to document current groundwater concentrations at the source area and in downgradient municipal wells; to assess threats posed to public health, welfare, or the environment; and to determine if further investigation under the CERCLA or Superfund Program is necessary.
The reassessment includes review of information available from federal, state, and local agencies; sampling to identify releases of hazardous substances to the environment and their existing pathways; and assessment of the need for a removal action.
EPA is committed to keeping the community and public informed of ongoing activities at the site.
