The UST was located adjacent to the residential structure’s foundation. ESI, through a soil investigation determined the extent of the impacted soil which extended beneath a corner of the residential structure and the standing deck.
A protective structural support system was designed and installed to support the residential structure adjacent to, and the standing deck above, the excavation area. Building permits from the Township were obtained.
Based on the results of the investigation, approximately 140 tons of impacted soil was excavated and disposed of at a licensed facility.
During excavation activities it was documented that groundwater was not present and/or in contact with the impacted soil; therefore, a groundwater investigation was not warranted.
Site restoration efforts included re-paving and/or sealing the driveway, backyard leveled as requested by the client and re-seeding. An AOC, Unrestricted Use – No Further Action & Covenant Not to Sue letter was issued by the NJDEP.
