IN-SITU CHEMICAL OXIDATION (ISCO) WITH TOTAL CHEMICAL MANAGEMENT

Project Scope

A Northeast engineering firm was selected to clean up a former roofing tar manufacturing site in Queens, NY. Following extensive bench testing and a comprehensive pilot study, they selected a treatment program using a remediation contractor’s surfactant enhanced In-Situ Chemical Oxidation (ISCO) technology. Due to the extent of contamination and the significant quantities of surfactant, sodium persulfate, and sodium hydroxide required, equipment and field services were required to remediate the site.

The remedial design required high flows (5-20 gallons per minute) of chemicals to be injected site-wide on a daily basis. This required storage and management of bulk chemicals on-site, creating operational and financial challenges for the contractor. USP Technologies developed a Total Chemical Management program to safely and cost-effectively execute the project. Safety and environmental compliance were critical considerations due to the project location in a highly-populated area and proximity to waterways.

Solution

Based on project requirements, USP developed a Total Chemical Management program to meet project schedules and budget objectives:

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. Project duration occurred over the winter and required equipment and operational adaptation to extreme cold, rain, and snow. Operations within close proximity to the public and public water required strict site safety and environmental procedures.
