The EPA R[emedial] I[nvestigation] data, compared with Army Corp benthic study, show that the DEP is dumping about six-inches of sludge into the upper canal each year. Even if we accept their model prediction to reduce sediment sludge from CSO's by 34%, that leaves us with an annual accumulation of about four-inches of sludge. The Superfund cleanup will be a major investment into the canal.
Is it OK to continue dumping that much sludge on top of the clean canal base? The DEP needs a plan that keeps this gunk inside their pipes and not at the bottom of the canal.
