Environmental Services

Federal environmental laws hold current property owners responsible for above-ground pollution or contamination of the soil/groundwater on their land even if it was caused by a previous owner. Phase I Environmental Site Assessments (ESAs) can uncover Recognized Environmental Conditions (RECs) through the assessment of historic records, aerial photos, government pollution reports, tank registries, and site reconnaissance of environmental conditions and potential hazards. Adhering to ASTM E1527 guidelines meets the “due diligence” standard, which allows property buyers and developers to comply with legal requirements of the Innocent Landowner Defense, and thus minimizes the risks of environmental liability associated with property transactions.

Phase II ESAs further explore RECs through the sampling and testing of soils, groundwater, and building materials. Through these practices, the presence of contamination can be documented and compared to state and federal standards, thus determining whether further environmental action (such as additional sampling, chemical testing, monitoring, or remediation) is warranted.
