Phase I Environmental Site Assessments

Environmental risks can slow or derail a deal. ASTI has completed thousands of Phase I ESAs for residential, industrial, commercial, and infrastructure sites, helping clients identify risks early and avoid costly surprises. Many of our assessments support brownfield redevelopment and financing programs at the State and Federal levels to start due diligence on solid ground. Our work gives decision-makers the confidence to move quickly without overlooking environmental liabilities.
