As part of the remedial investigations, Evergreen compared the lead data to the Act 2 soil-to-groundwater Statewide Health Standard, which is 450 parts per million (ppm) and the direct contact Statewide Standard, which is 1000 ppm, as well as the Site Specific Standard. This comparison is shown on the figures/tables in the Remedial Investigation Reports and in the 8/27/20 presentation. The Remedial Investigation Reports only report the data, no remedial decisions relating to the use of lead Site-Specific Standard are included in the Remedial Investigation Reports. The approved Site-Specific Standard for lead is based on updated information and models from the EPA and PADEP that reflect the current state of science for lead. Evergreen will modify the Site-Specific Standard if the PADEP or the EPA modifies these models or assumptions. If the PADEP changes their assumptions related to lead, such as permissible blood lead levels, Evergreen will update the Site-specific standard accordingly.
