Princeton Theological Seminary Historic Pesticide Sampling

Project Description

ACT Engineers conducted a remedial investigation to delineate the horizontal and vertical extents of pesticide contamination associated with the historical agricultural operations at the site. A total of 144 soil samples were collected and analyzed. In an effort to minimize environmental costs, the Thiessen Polygon Method was utilized to evaluate hot spots areas and determine volumes to be remediated/excavated in order to achieve regulatory compliance.

ACT’s responsibilities also included coordination of NJDEP notification and LSRP retention, completion of a Remedial Investigation Work Plan (RIWP), Remedial Action to remove impacted soils, and submittal of a Remedial Action Report (RAR) to support the Remedial Action Outcome.

ACT Engineers was responsible for the coordination of Public Notification as required for contaminated properties by the NJDEP. This task included on-going support to address resident/staff concerns about the remedial investigation process including the coordination of an Informational Meeting for residents.
