Is a 10’ deep soil sample deep enough to reach contaminants located below the surface fill that would have been used to cover the landfill? Will EPA be taking core samples at a later date that go deeper - 20’, 30’, or 40’ deep?
There are no plans to conduct additional soil sampling in the landfill or dump areas at this time. Soil borings advanced into the dump and landfill areas at the depths achieved in this investigation were sufficient for encountering solid waste buried beneath the surface. Soil borings that were advanced in the residential areas reached up to 10 feet below the surface, with a soil sample collected from that interval. EPA does not anticipate that residents will come into regular contact with soils at depths greater than two feet below the surface.
