Remediation Feasibility Testing

Northstar is capable of self-performing remediation feasibility testing. Northstar believes that remediation feasibility studies (pilot tests) at sites with impacted soil and groundwater are one of the most critical steps in the site remediation process. Feasibility tests commonly conducted for Northstar customers include aquifer testing (including step-drawdown, constant-rate, and recovery tests), soil vapor extraction (SVE) and dual-phase extraction (DPE) testing, air sparge and in-situ groundwater remediation pilot studies (chemical oxidation, bioremediation).
