We provide site characterization services to identify the lateral and vertical extent of contaminants in the soil and groundwater and impact that may be present in surface water. Analysis is performed on the degree of impact on the natural environment relative to background or baseline conditions. Forensic-type evaluations can be performed to evaluate the source of contamination either as a function of time or location. Impacts are assessed for cost-effective remedial strategies to mitigate impacts and initiate performance monitoring.
