Phillipsburg, NJ

Time Frame: September 2018 - February 2019

Enviro-Air was contracted to excavate and remove contaminated soil to a depth of 48 feet below ground level. In addition, EAT was required to excavate foundry sand from a 3-acre area and use that material as backfill in the excavation. A small TSCA PCB area was excavated, transported and disposed of at a hazardous waste factility. In addition, 12,000 tons of impacted soil were shipped to a Pennsylvania landfill. After the excavation was filled with the foundry sand, it was capped, and the entire 3 acres site was restored.

Time Frame: January - June 2016

EAT was contracted to excavate and remove both known and unknown substructures and piping, MGP impacted material and TSCA-level PCB impacted material from an area directly adjacent to an active natural gas facility. This project encompassed several different waste streams that required extensive effort to excavate, manage on site, stockpile, transport and dispose of at multiple treatment/disposal facilities. The known/unknown substructures included a tar holder, USTs, concrete pads, timber piles, abandoned natural gas piping and asbestos wrapped piping. Dewatering and handling/disposal of impacted groundwater was a challenging aspect of this project.

Seven (7) waste streams were excavated, segregated and stockpiled on site including:
- TSCA PCB soil
- TSCA PCB pipe/debris
- Low level PCB soil
- Low level PCB debris
- MGP soil
- MGP pipe/debris
- Clean pipe/metal
Excavated, transported and disposed of:
- 2,500 linear feet of underground piping
- 500 tons of TSCA PCB impacted soil, piping and debris
- 5,000 tons of low level PCB impacted soil and debris
- 800 tons of MGP impacted soil
- 180,000 gallons of MGP impacted and PCB impacted water

EAT finished the project ahead of schedule.
