ENVIRONMENTAL ASSESSMENTS WSP personnel have been conducting environmental site assessments (ESAs) since the inception of this type of assessment, both regionally and nationally. ESAs are performed in accordance with the American Society of Testing and Materials (ASTM) standards and the All Appropriate Inquiry rule issued by EPA and state agencies Site Characterization Guidance document. Our team of engineers and scientists includes world class experts in the assessment and remediation of contaminated soils, groundwater and surface water.

Contamination Assessments If it is determined that contamination is present, an additional sampling effort, such as a Phase III ESA, may be conducted to assess the extent of contamination. Contamination assessments are conducted to more completely identify the source, nature, character, and extent of contamination. WSP would then make recommendations as to the technical and economic feasibility of remedial (cleanup) alternatives. We have the resources available to implement a risk based cleanup and confirmatory testing and post-cleanup monitoring. Remediation WSP’s experience relates to a wide array of remediation activities and technologies such as the installation and operation of in-situ remediation systems for soil excavation and source removal, containment and capping systems, and long-term monitoring programs. Our project managers have decades of experience in site characterization, pathway evaluation, feasibility studies, and corrective action implementation.

Our staff has completed numerous ESAs including Phases I, II, and III; Preliminary Contamination Assessment Reports; Contamination Assessment Reports; and Remedial Action Plans (RAPs). WSP offers a wide range of services that will provide the information necessary to effectively evaluate potential environmental risks. Phase I and II ESAs WSP’s ESAs are conducted in general accordance with provisions of ASTM standards which identifies a typical level of care, limitations and purposes of such assessments. Work completed during a Phase I ESA is primarily intended to evaluate whether current or past land use may have potentially affected soil, surface water and/or ground water quality as well as identify whether a site has been potentially affected by the surrounding property activities. Phase II investigation strategies are developed based upon the results of a Phase I ESA, and can be used to evaluate the possible effects of a known release or to evaluate for a possible release. A Phase II typically involves collecting and analyzing samples to evaluate if the media have been impacted by contamination. Results of the Phase I ESA will be used to identify analytical parameters and sampling strategies for an assessment. Analytical parameter groups are typically fairly broad and intended to investigate several different types of contamination.
