Environmental Site Assessment Services

Athenica has a team of geologists, engineers, and environmental professionals who conduct Phase I Environmental Site Assessments (Phase I ESAs) and Phase II ESAs throughout the New York Metropolitan area.
Our Phase I ESAs meet the requirements of the current American Society for Testing and Materials (ASTM) standard and the EPA All Appropriate Inquiries, and consist of a Site visit, and a detailed analysis of regulatory database search report, local records, and available historical documentation. 
Our Phase II ESAs are designed to provide a focused evaluation of subsurface conditions based on the findings of prior studies and/or specific project requirements of our clients. 

The Phase II ESA can include the following:

• Geophysical survey,
• Installation of soil borings or direct-push borings, test pits, and permanent groundwater monitoring wells,
• Screening of soil and groundwater conditions in the field for evidence of contamination
• Collection of soil, groundwater, soil gas, sub-slab vapor and indoor air samples for laboratory analysis
• Determination of ground water flow direction and other aquifer properties (hydraulic conductivity, hydraulic storativity, etc.)
• Evaluation of laboratory results by comparison to applicable regulatory standards and/or guidance values
