The USEPA declared the land that once contained two dumps and a large development facility in New Jersey a Superfund Site. Substandard hazardous waste handling and disposal practices at previous onsite facilities had contaminated the surrounding environment with dangerous levels of VOCs, Heavy metals, and PCBs. WaterSolve, LLC was involved with a phase of this remediation project that consisted of removing over 30,000-cubic yards of contaminated sediments from the river adjacent to the property.

GEOTUBE® CONTAINER SIZING

Geotube® containers were the tubes of choice for this project and are manufactured from high strength polypropylene fabric and designed to allow effluent water to escape through the pores of the fabric while retaining the chemically-conditioned solids. The Geotube® Estimator, along with comprehensive sediment sampling and lab testing were used to determine the amount of Geotube® containers required. A two acre lay-down area was designed to hold up to three layers and over 5000 lineal feet of 80’ circumference Geotube® containers.

WATERSOLVE’S CHEMICAL CONDITIONING

Extensive testing was performed on representative sediment samples by a WaterSolve technician in the facilities laboratory. Dewatering polymers were evaluated based on water release rate, water clarity, and flocculent appearance. In addition, dosing rate(s) were determined during bench-top dewatering experiments and recommendations provided to the contractor during this phase of the program. It was determined that a dual chemical treatment of Solve 426 and Solve 2220B would be most effective for this project.

THE RESULT

The contractor selected by the USACE for this phase of remediation contracted with WaterSolve to help with the dewatering portion of the project. WaterSolve was tasked to provide Geotube® containers, Polymer Feed Equipment, Polymer and the technical assistance for daily operations. The project was deemed a success after four months of dredging when over 30,000-cubic yards of contaminated sediment was pumped to and dewatered in over 5,000 linear feet of Geotube® containers.
