I work for the Department of Environmental Protection here in NYC and I can tell you that the water is MUCH cleaner than it has been in almost 100 years. In the mid 80's the North River Waste Water Treatment Plant was the final Treatment Plant to come online and ended the practice of NYC expelling waste water (human waste, soaps, detergents, grease etc.) from entering the waterways. As we monitor the waterways we can see aquatic life returning to the area which we have not seen in many years. I do take exception to the "science being settled" comment as shut down of debate is not true science and therefore becomes a narrative.
