On Sunday, August 20, from 8 AM to 3 PM, bring your household hazardous materials to our next S.T.O.P. event at Town Parking Lot at 200 North Franklin Street in Hempstead. The program is designed to provide area residents with a safe, environmentally sound method of disposal of the many hazardous materials found in the average home. By bringing such toxins as antifreeze, drain cleaners and pesticides on any of the scheduled S.T.O.P. collection days, you and your family can make a significant contribution to the protection of our precious groundwater supply and the preservation of our bays and estuaries. You can bring your old thermostat containing mercury to a S.T.O.P. event, keep mercury out of the waste stream and receive a $5 gift card to a local home center compliments of Covanta Energy (limited # of offers per household).
