Residual Risk Assessment
with Remedial Goals

A residual risk assessment was prepared for a site that evaluated potential impacts to an adjacent right-of-way.  Due to increasing plume trends observed in the vicinity of the source area after remediation activities, a post-remedial care plan was necessary to monitor future plume migration to off-site areas.  This post-remedial care plan incorporated periodic sampling of select monitoring wells based on a complex hydrogeologic CSM.  A site-specific series of groundwater monitoring criteria were developed for both on-site and off-site receptors (both direct contact and vapor intrusion) in order to assess future groundwater results to ensure continued attainment of PADEP risk benchmark criteria.
