In September of 2017, OEPA requested assistance in further evaluating the American Legion Trailer Park Site. Previous assessment had identified lead concentrations, in surface soils, ranging from non-detect to 4,810 milligrams per kilogram (mg/kg). Nine of the samples exceeded the EPA Residential Removal Management Level (RML) of 400 mg/kg.
EPA conducted a removal evaluation on June of 2018. Sampling identified lead concentrations in surface soils ranging from 105 to 4,390 mg/kg and TCLP results ranging from 0.016 to 170 milligrams per liter (mg/L). In August of 2018, EPA, in coordination with OEPA, Ohio Department of Health and Zanesville-Muskingum County Health Department, held a meeting with residents to present the results and address any questions or concerns.
In September of 2018, EPA mobilized contractors to stabilize Site conditions, by providing temporary cover to exposed soils, until a Time-Critical Removal Action could be conducted.
The Action Memorandum was signed on May 15, 2019 and EPA began Site setup the week of June 24, 2019 with full mobilization beginning on July 15, 2019.
