The main question that EPA seeks to answer is whether the identified waste areas warrant consideration for placement of the Site on the National Priorities List (NPL) or Superfund List.

In the first round of sampling, EPA collected surface soil samples (0-2 feet) from the landfill property, and surface water and sediments of the Muckinipattis Creek to determine if any contaminants are impacting the sensitive environments of John Heinz National Wildlife Refuge.

EPA also conducted soil sampling at 21 residential homes in May 2018 to determine whether or not contaminated fill was found on residential properties within the Winona Homes and Norwood Acres Neighborhoods.
