Environmental Site Assessment

Coastal Testing Laboratories provides comprehensive Environmental Site Assessment (ESA) services to help clients evaluate environmental conditions prior to property acquisition, development, or redevelopment.

Our experienced team performs site reconnaissance, readily available records research, and interviews to prepare Phase I Environmental Site Assessments in general accordance with ASTM E1527-21.
If a Phase I ESA identifies recognized environmental conditions, CTL can perform a Phase II Environmental Site Assessment, which may include subsurface sampling and laboratory testing to evaluate the presence and extent of potential environmental impacts.

Whether supporting commercial, industrial, or municipal projects, CTL’s environmental professionals prepare reports intended to assist clients in making informed decisions regarding environmental conditions and associated risks
