The City of New York is among the potentially responsible parties (PRPs) required to clean up Newtown Creek and Gowanus Canal from historical pollution that led to superfund designation in early 2010s.
Although historical pollution in Newtown Creek and Gowanus Canal is attributed to organic contaminants, the combined sewer overflows (CSOs) and stormwater (point sources) from City’s outfalls do contribute sediments into these waterbodies that the organic contaminants can attach to.
Our staff led the review of IW models of Newtown Creek drainage area for various parties including New York State and USEPA and established the legal basis for using the City’s models for superfund analyses. Boomi evaluated a range of alternatives involving storage tunnels and tanks, high level sewer separation, green infrastructure, and pump station upgrades to mitigate the impacts of CSOs on these two waterbodies.
