PHASE I ESA
A Phase I Environmental Site Assessment (ESA) is the initial phase for assessing a property of interest. Here site reconnaissance, historical information and documentation are compiled to determine if other avenues are required to further investigate a property for possible signs of hazardous waste.
PHASE II ESA
A Phase II Environmental Site Assessment (ESA) is usually initiated when recommended in a Phase I ESA. Basically, a Phase II ESA is conducted to establish the chemical makeup of the soil and groundwater in order to determine if there are significant amounts of contaminants that may require remediation or monitoring, or create land use limitations.
An underground storage tank (UST) system is an Area of Concern (AOC). When an UST is suspected of a release, when it is to be closed, removed, or when it is to be temporarily taken out of service an investigation may be required.
SOIL SAMPLING & WATER MONITORING
Soil samples are taken to analyse the chemical makeup of the soil on which your property stands. CAS also conducts groundwater monitoring of property to document the levels of any possible on-site groundwater contamination.
The purpose of the U.S. Environmental Protection Agency (EPA) Spill Prevention, Control & Countermeasure (SPCC) rule is to help facilities prevent a discharge of oil into navigable waters or adjoining shorelines.
