North Castle Prescription Drug Take- Back Program 2015 
Previously, consumers had been told to flush unwanted drugs. However, since low levels of some drugs are being found in our surface water, this has no longer been recommended. Residents can safely dispose of unused prescriptions, OTC medications and vitamins 24 hours a day, seven days a week at the new North Castle Drug Collection Unit .This metal green unit (similar to that of a mailbox) has been installed in the lobby of the Police Department which is located in Town Hall.

Managing and Disposing of Household Hazardous Waste NYSDEC
Every year in New York State, more than 100,000 tons of these household hazardous wastes are emptied into trash cans. They end up in landfills or incinerators. They may also enter the environment from lawns, sewers and septic systems. To protect and preserve the quality of our groundwater, streams and lakes follow these guidelines.
