Former Millcreek Cash Saver / Corrective Action

Client: Premium Oil Company, PST Fund
Location: Salt Lake City, Utah

SAGE developed a Corrective Action Plan (CAP) based on the findings of previous site investigations conducted at this former underground storage tank site. The CAP evaluated a variety of remediation methods comparing cost, effectiveness, and applicability to subsurface conditions. With the property now redeveloped as a busy drive-through restaurant, access constraints and public safety were also considered when developing the plan.

Chemical injection was selected as the remedial technology; the CAP included baseline and follow-up groundwater monitoring to evaluate the effectiveness of the treatments. To avoid impacting the operating business, chemical injections were performed at night, after the restaurant had closed. Follow-up groundwater monitoring demonstrated that contaminant concentrations decreased in the areas where the injections occurred; site monitoring is ongoing.
