CEA has conducted site assessments and/or subsurface investigations at hundreds of contaminated properties including commercial properties, former industrial properties and residences. The goals of most site assessment programs are: (1) to confirm or deny the presence of environmental contamination at a Site; (2) to define the extent of the media contamination, if present; (3) to support development of a Conceptual Site Model and performance of a human health and ecological risk assessment; and (4) to support the development, evaluation and selection of Remedial Action Alternatives (RAAs) for a Site. Typically, site assessments include:
- State, Local and Federal File Reviews
- Site Reconnaissance and Field Screening Activities
- Media Sampling & Analysis/Subsurface Investigations
Most site assessments involve advancement of a minimum of three (3) soil borings completed as groundwater monitoring wells, and sampling and analysis of soil and groundwater to evaluate subsurface conditions.
