Subsurface Investigations and Site Remediation

We help businesses evaluate and clean up contaminated sites to minimize risk, contain costs, protect human health, and restore the environment.

Focusing on our clients’ long-term goals and strategies, ATC helps minimize costs and risks when conducting property assessments, remediating known environmental issues, or developing contingency plans to prepare for a future response.

Each year we conduct thousands of Phase I and Phase II Environmental Site Assessments (ESAs) to identify, analyze, and resolve property environmental conditions. We help clients design sampling plans and remedial programs, select cleanup technologies, prepare comprehensive findings reports, and manage the permitting process, and we provide expert witness testimony as well.

We are deeply experienced in soil, soil vapor, and groundwater remediation strategies through both traditional and innovative means including chemical, biological, and physical mass removal technologies.
