Broadbent Remediation Compound

Broadbent has been providing environmental consulting and engineering services to a major oil and gas company, since 1989, focusing on underground storage tank (UST) and leaking underground storage tank (LUST) facilities. Broadbent has retained a contract with this company through numerous highly competitive consultant consolidation procurement events and in recent years has successfully expanded services with the client. In 2011, Broadbent was awarded a Master Service Agreement to provide Environmental Consulting and Engineering Services to the major gas and oil company, across North America. Currently, Broadbent is working as the client’s consultant on 36 LUST projects in California and Nevada and is a key consultant at an acid rock drainage project located at a former mine in the Sierra Nevada Mountains (Alpine County, CA).

Work performed by Broadbent for the client on UST and LUST projects includes:

  • Phase I Environmental Site Assessments;
  • detailed site characterization activities and preparation of conceptual site models;
  • soil vapor studies to investigate potential vapor intrusion concerns;
  • groundwater modeling for determining contaminant plume migration and containment;
  • remedial efforts;
  • risk assessments;
  • and preparation of regulatory closure request packages.

Remedial technologies designed and implemented on the client UST and LUST projects by Broadbent include:

  • soil excavation;
  • groundwater pump and treat;
  • soil vapor extraction (SVE) in conjunction with air sparge (AS);
  • dual phase and mobile dual phase extraction;
  • vacuum enhanced extraction;
  • enhanced in situ bioremediation including injection of oxygen releasing compounds and hydrogen peroxide (aerobic) and sulfate (anaerobic);
  • and in-situ chemical oxidation (ISCO).

The objective of these activities is to work with the client, and the respective regulatory agency, to protect human health and the environment and ultimately move sites to regulatory closure.
