Our team supported a Remedial Systems Optimization effort for NYS Part 373 permit compliance at a major RCRA-regulated chemical manufacturing Treatment, Storage and Disposal Facility on the Hudson River in Eastern New York. Work involved the examination of over 40 years of geochemical data in a complex hydrogeological terrain utilizing state of the art visualization and groundwater modeling software. The resulting work limited pumping configuration from 650 gpm at 50+ wells to under 400 gpm from many less wells pumping at lower rates, providing significant savings in long-term treatment costs.
