EC&A provides a full range of geological, hydrogeological, engineering, environmental management and contracting services for investigation and cleanup of hazardous substances releases. Our services are most commonly employed to investigate and remediate releases of petroleum hydrocarbons from underground fuel storage tanks (USTs), or waste dry cleaning solvents that have impacted soil and groundwater as a result of long-term disposal onto the ground surface, or escape through breaches in sanitary sewer lines. For unknown substances, we collect samples, have them analyzed at an appropriate laboratory and report the results with our conclusions and recommendations.
