Phase II ESAs are usually performed after a Phase I ESA has identified an environmental concern.
The Phase II ESA may simply consist of surficial soil sampling and screening with an organic vapor
analyzer, or it may consist of a comprehensive assessment involving monitoring well installation,
soil and/or ground water sampling and analysis, and/or ground water elevation surveys. On more
complicated sites, a Phase II ESA may involve employing a geophysical survey to locate buried
waste or tanks. A Phase II ESA report typically includes a site plan, description of procedures, a
summary of the test results, and conclusions and recommendations.
