Phase I Environmental Site Assessments allow our customers to identify past, present, or potential hazardous substance conditions. In 1980, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) made landowners liable for the environmental condition of their property. Site assessments can determine hazards before, during, or after purchase. If discovered after purchase, previous landowners may still be liable under the “innocent landowner defense”. |
Because no sampling or testing occurs, Phase I Assessments do not quantify or prove contamination. Instead, assessments create a picture of current environmental conditions and investigate the site's history.
All assessments conducted by CIH Environmental Solutions comply with the American Society for Testing and Materials' standard E-1527-05, which includes:
- Site history development of property and surrounding area using available documents, records, maps, and interviews.
- Visual inspections for recognizable environmental conditions like spills, bulk storage tanks, and hazardous materials.
- Review of available federal, state, and local government documents to determine the environmental condition of surrounding properties. This includes site histories and covers environmental contamination or violations indicating possibility of contamination.
- Any additional information necessary to determine if further action or emergency action must take place (or if additional investigation is required).
