Gas Station Remediation (ISCO)

Total Chemical Management for Remediation

A remediation company was contracted to perform a cleanup of an abandoned gas station in south central Pennsylvania. The consulting engineer and the remediation contractor selected a treatment program utilizing In-Situ Chemical Oxidation (ISCO) as the preferred treatment technology. Due to the magnitude of the contamination and the widespread nature of the groundwater contamination, significant quantities of chemical (hydrochloric acid, ferrous sulfate, hydrogen peroxide, and sodium persulfate) and equipment were required to execute the site remediation. The scope and structure of the project required that a high volume of multiple chemicals be mobilized quickly which created a significant operational and cost challenge for the contractor. USP Technologies developed a Total Chemical Management program to efficiently, and cost-effectively, execute the project.


Based on the requirements for the project, USP developed a Total Chemical Management program to meet project schedules and budget objectives, which included the following:

Site Analysis and Hazards Review

USP engineering personnel worked closely with the remediation contractor to evaluate and plan for the specific hazards of the project site. Equipment was selected to ensure the chemical containment site security provided additional public protection. In addition, a water storage tank for emergency response and to support product dilution requirements was required as only a restricted-flow water source was available.
