Between now and August, New York City’s Department of Environmental Protection (DEP) will be using chemical treatment in four local reservoirs to control overgrowth of algae: The New Croton, Muscoot, Cross River, and Croton Falls.

The DEP will also be treating the New Croton Reservoir for Hydrilla, an invasive weed that was first discovered in the reservoir, and in the Croton River, in 2014.  MORE AT Algae and Hydrilla are back in our reservoirs, and so are the chemicals used to treat them.
