Aquatic Pesticide Applications

Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Aquatic Pesticide Application

Regulates the use of chemicals proposed for introduction into the waters of the state, whether public or private, for control of aquatic organisms. These organisms are usually aquatic weeds or algae, but could include mosquitoes or unwanted fish. Applications are evaluated for the potential of causing unreasonable adverse effects to human health or the environment. Only chemicals registered for aquatic sites may be used.
