Our consultants have performed Environmental Site Assessments (ESAs) in almost every U.S. State as well the Virgin Islands and Jamaica.

We have performed hundreds of soil and groundwater investigations.  We are experts in soil excavation and remediation.  We are experts in groundwater remediation design/installation/operation and the owner and manager of LP Environmental invented and co-holds a U.S. Patent for groundwater remediation.

ENVIRONMENTAL SITE ASSESSMENTS

Phase I Environmental Site Assessments
Phase I ESAs are an essential part of property acquisition due diligence.  The ESA identifies recognized environmental conditions (RECs) associated with a property.  The following scope is typical of a Phase I ESA:

Site Inspection - a qualified environmental professional performs a site inspection to determine current uses of the subject property.  Hazardous substances and petroleum products, underground and aboveground storage tanks, chemical storage, storm water drainage, evidence of historical conditions, environmental permits, transformers, and other items are documented.

Neighboring Properties - during the site inspection, the neighboring properties are inspected to determine potential impact to the subject property.

Interviews - interviews are conducted with persons knowledgeable of the subject property.  Persons can include current and past owners, site managers, employees, neighbors, and tenants.  An interview with the local government official (e.g., fire marshal or local HazMat) is conducted to determine if any emergency response has occurred at or near the subject property.

File Search - a file search is performed on the subject property and properties within the required search radii.  Environmental files are investigated for registered underground storage tanks, drycleaners, brownfields, historical contamination or remediation, wetlands delineation, monitoring or drinking water wells, and other environmental information.  Historical documents are also researched included aerial photography and USGS topographic mapping in the vicinity of the subject property.

Phase II Environmental Site Assessments
Phase II ESAs may be recommended on a property in which the owner or perspective buyer needs to confirm the severity of Recognized Environmental Conditions (RECs).  A typical reason to conduct a Phase II ESA would be if the site had a current or former underground storage tank and the owner or perspective buyer wanted to determine if a release had ever occurred.  The Phase II involves soil and groundwater testing and compares data to State and Federal regulation levels.

Phase III Environmental Site Assessments
A Phase III ESA is the remediation design phase.  If the Phase II ESA determines that contamination exists and the responsible party wishes to remove, abate, or control that contamination, then a Phase III ESA may be performed to determine the remedial options, engineering/institutional controls, costs, and degree of regulatory involvement that is necessary.  Typically, the end product of the Phase III ESA is an approved work plan and cost summary/estimate.

Phase IV Environmental Site Assessments
The Phase IV ESA is the remediation or engineering/institutional control implementation.  This is the field work task of the remediation or engineering/institutional controls.  If an underground storage tank is found to have released gasoline, then this phase will likely include excavation and disposal of dirt in the area around the underground storage tank.  Confirmation sampling would also be required for a no further action letter from the State environmental agency.  Another example would be a treatment system installation or injection of bio-enhancements to remediate contamination in groundwater.
