Western Pennsylvania

Site Conditions
– Source Areas & Groundwater Plumes
Western Pennsylvania –
TCE/TCA with plume in Soil
(TH: 5-15 ft) & Fractured Bedrock
(TH: 15-35 ft)

Pennsylvania – Installed, 2013

 

Combined Technologies Approach
Source area treatment

  • Excavation of 1500 tons of highly impacted soil
  • Enhanced In-Situ Bio (EISB) & In-Situ Chemical Reduction (ISCR)

TCE/TCA in Two Groundwater Formations (5-15 & 15-35 ft)

  • TreeWell units to address both aquifer horizons

Source Area Total CVOCs – 262 mg/l

Downgradient Wells – From Sept.,2012 to Mar.,2016
Shallow dropped from 25 to 5 mg/L

Deep dropped from 95 to 45 mg/L
