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.

US Peroxide was contracted to provide total chemical management including chemicals, logistics, field services, equipment mixing and storage systems as well as chemical management oversight for the remediation of pesticides and petroleum products at a site located in California.
Due to significant dry chemical requirements as well as a large square footage application treatment area, this project included the need to design a novel way to spread supersack quantities of chemical in a controlled manner. The resulting system pictured uses a device at the end of the spreader to accomplish this task. Equipment requirements included three 3-ton capacity dry material spreaders, all terrain tractors and a 3-ton all-terrain forklift system to distribute dry chemicals.
US Peroxide can supply a wide range of chemicals such as hydrogen peroxide, ferrous sulfate, sodium persulfate, sodium percarbonate, acids and others commonly used for ISCO or other remediation technologies. These chemicals are available in wet (drum, tote, bulk) or dry (bags or super sacks where applicable) form. USP works with remediation companies to develop a cost effective, logistically optimized, and reliable chemical management program based on project specific chemicals, quantities, usage rates and other project constraints.[/vc_column_text][/vc_column][/vc_row]

USP combines experienced applications and equipment field support with a large inventory of storage systems and pumping modules to respond quickly to time sensitive water and wastewater treatment situations.
USP Technologies’ 
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.
