Phase I and Phase II Environmental Site Assessments

One Stop Environmental regularly performs Phase I and Phase II environmental site assessments for our clients. This due diligence affords them liability protection under the American Society for Testing and Materials (ASTM) 1527. We use in-depth site investigation, personal interviews and historical research to uncover potential contamination or other environmental conditions on a given site. We use the ASTM standard to prepare our reports, and we are more than happy to tailor our research to focus on your specific concerns. We serve the following industries:

We are used to working under tight deadlines. Even if you have waited until the last minute to schedule Phase I and Phase II environmental site assessments, call us.

What is a Phase I Environmental Site Assessment?

Our teams of environmental consultants review site records and perform a site inspection. They conduct interviews with owners, occupants, neighbors and local government officials. Our Phase I’s also include sampling and laboratory analysis by an environmental professional trained in the appropriate standards. Depending on the results of the samples, the Phase II ESA should outline additional site investigation needs, and potential remedial actions that may be required to clean up the property

What is a Phase II Environmental Site Assessment?

If a Phase I ESA identifies potential contamination of the site by hazardous materials, we will perform a Phase II ESA. The Phase II includes sampling and laboratory analysis to confirm the presence of hazardous materials. Some of the tests we may perform include:

  • Drum sampling (if any were left on the property)
  • Surficial soil and water samples
  • Sampling of dry wells, floor drains and catch basins
  • Testing of underground storage tank
  • Subsurface soil borings
  • Groundwater monitoring well installation, sampling, and analysis (may be appropriate on neighboring properties as well to determine the presence of contamination)
  • Transformer/capacitor sampling for Polychlorinated Biphenyls (PCBs)
  • Geophysical testing for buried tanks and drums
  • Asbestos, lead, and other regulated material testing
