Frog Switch - Carlisle PA - Supplemental Phase II Environmental Site Assessment

This contract involves conducting a Supplemental Phase II Environmental Site Assessment (ESA) at the Frog, Switch & Manufacturing Company property, a 31-acre site located at 600 East High Street in Carlisle, Pennsylvania. The assessment builds upon a 2025 Phase II ESA that identified soil contamination from several metals and polycyclic aromatic hydrocarbons. The primary goals are to further delineate the extent of soil contamination through expanded sampling and to collect background samples to establish a reference standard for arsenic, a naturally occurring contaminant of concern. The site is characterized by silty clay soils overlying limestone, with surface soils consisting primarily of loams, sands, or fill material, and no groundwater encountered above the limestone formation. The solicitation for this contract was issued by the Department of Commerce under the Volpe National Transportation Systems Center, with a total small business set-aside designation and NAICS code 238910. The contract opportunity was posted on April 6, 2026, with a response deadline of May 4, 2026. The place of performance is Carlisle, Pennsylvania, and the primary point of contact is Roland Regan. The contract aims to provide a more detailed understanding of the contamination to inform any necessary remediation or risk management actions.
