Brief Site History

The River’s Edge Development Site (the Site) is located at 484-490 Boston Post Road (Route 20), Wayland, MA. The Site is located directly east of the Sudbury Landfill, southeast of the Wayland Transfer Station, and approximately 1,500 feet west of the Sudbury River. The Site formerly operated as a wastewater treatment plant, municipal firing range, and DPW storage yard.

Environmental assessments completed at the Site have identified oil and/or hazardous materials (OHM) at concentrations that required the MassDEP be notified. These notifications are identified by MassDEP as Release Tracking Numbers (RTNs), which are used to keep track of the assessment and remediation activities at the Site. A brief explanation of each of the RTNs, and the associated documents pertaining to the assessment and remediation of the OHM associated with each of these RTNs are found below.
