Environmental site audits are comprehensive property evaluations which address historic and present uses to determine what environmental concerns may exist. Assessments are conducted in phases. A Phase I Assessment is trying to answer one important question: Is there any indication that an environmental hazard may still exist on the property?
If the Phase I concludes a hazard may be present, then the report will recommend that a Phase II Assessment be conducted. The Phase II Assessment will use direct investigative techniques to quantify the extent of any hazards and make recommendations on necessary remedial actions.
Phase III work will mitigate the problem.
Phase I assessments include but not limited to the following tasks:
· Review of pertinent geologic and hydrologic literature and maps.
· Review of historical aerial photographs and archival land use maps.
· Review of federal, state, county, and municipal records of known and suspected hazardous waste release sites at the subject property and/or within the immediate surrounding areas.
· Reconnaissance of the subject property and the immediate surrounding areas. The site reconnaissance includes conducting interviews with past and present property owners and managers to assess past and present operations and maintenance procedures.
· Contact of local regulatory agencies regarding past site use, notices of violation, suspected problems, and noncompliance issues.
· Preparation of a summary report including our investigative methods, findings, photographs, conclusions, and, if warranted, recommendations for additional work
Phase II assessments include but not limited to:
- Development of a comprehensive sampling plane in accordance with Federal, State and Local governmental agency requirements
Phase III assessments include:
-Development of a mitigation plan to neutralize or remove the hazardous materials in accordance Federal, State and Local agencies.
Hazardous material investigation:
Baseline Surveys are conducted at facilities that intend to install containment structures or handle hazardous materials. Ideally, the survey is designed and data are collected prior to any construction. Once the facilities are constructed, another baseline data set is collected. These two data sets serve as the original uncontaminated images of the facility to which any future data sets are compared.
Subsequent surveys are collected at periodic intervals as a method of monitoring the facility or at any time in the event of a material release. Discrepancies between the baseline data sets and subsequent data sets highlight the areas of concern. The extent of contamination or even the existence of a release can be quickly identified and quantified.
Creating a baseline data set provides extremely valuable information if you are faced with a catastrophic event or when used with a regular monitoring program. Baseline data can be your insurance policy against speculative litigation.
