Phase II ESA of a Known Contaminated Site

Texas A&M University System

Dallas, Texas

A contaminated site at the Texas A&M University Health Science CenterSince contamination was already known to exist on this site, the primary objective was to gather enough information so that the client could make a rough estimate of potential treatment and disposal costs with either minor resurfacing, or major construction. The practical concern was to determine the quantity of hydrocarbon affected soil that would require special handling, treatment and disposal should it be exposed in the course of construction. The client also desired limited additional sampling conducted to determine if chlorinated solvents had migrated onto the site from an off-site source and what additional data would be necessary to form the basis for an innocent owner/operator certificate application for the site.
