Agency Focus: New York City Department of Environmental Protection

When New Yorkers turn on a faucet at home or at work, it’s assumed that the water coming out is safe to drink. It goes without saying that the air we breathe ought to be clean, and that the waterways surrounding the city should be uncontaminated. Local residents look to municipal government to keep noise levels under control, and city officials are expected to do whatever they can to improve the city’s resilience to major storms.

In New York City, all of these tasks – and more – are carried out by the Department of Environmental Protection. In its own words, DEP’s mission is to protect “public health and the environment by supplying clean drinking water, collecting and treating wastewater, and reducing air, noise, and hazardous materials pollution.”

In other words, the agency of nearly 6,000 employees does many of the things that residents take for granted. While the DEP only seems to make headlines when there’s a problem, in this special section, we take a closer look at some of the major projects that are critical to the city’s health.

New York City Waste Water treatment plant

New York City generates a lot of waste.
