Technical Guidance

Remediation and investigation activities are guided by the Delaware Risk-Based Corrective Action Program (DERBCAP), a risk-based clean up approach that assesses the risks associated with petroleum and chemical impacts to soil and groundwater. If remediation is required, DERBCAP is used to develop clean up goals.

To assist consultants, responsible parties, and the public through the investigation process, the Corrective Action Program has developed a collection of guidance documents.

Environmental Investigation and Remediation Consultants

The Division of Waste and Hazardous Substances maintains a list of Environmental Investigation and Remediation Consultants. This list is provided to the regulated community to help select an environmental consultant for the investigation and remediation of leaking underground and aboveground storage tank sites.

Inclusion on the list does not imply endorsement, recommendation or certification of the consultants by the Division. This list may be subject to modification, addition and/or deletion of consultants at any time without notice.
