Site Investigations and Field Services

Our environmental professionals start with the development of the site investigation work plan.  We typically employ the Data Quality Objectives (DQOs) approach developed by the US EPA for conducting data collection activities associated with risk assessment and remediation engineering. We define a preliminary list of potential chemicals of concern.

The next step is to develop the appropriate risk-based screening criteria and to identify potential receptor populations.

From the risk-based screening criteria, the laboratory analytical procedures are developed which provide for types of analyses, analytical detection limits, and  proper sample collection and handling procedures.  Incorporated into our sampling plans are Standard Operating Procedures that have proven successful throughout numerous field investigations.

The last step in the site characterization process is the development of the Site Investigation Report or Affected Property Assessment Report. Streamlined procedures for sampling and data analysis reduce the report preparation time and allow us to provide higher quality and less costly reports.

Included in our program are special negotiated rates with many of the subcontractors that are commonly used during field operations. These include drilling subcontractors, analytical laboratories, equipment rental companies, and specialty instrument companies. These cost savings allow us to provide the highest quality services for reasonable prices.
