Why This Matters
Improper disposal of pesticides can pollute soil, groundwater, and surface water, posing risks to humans, pets, livestock, and wildlife. Since 1982, Maine’s Obsolete Pesticide Collection Program has safely diverted more than 250,000 pounds of hazardous pesticides from the waste stream.
Collected materials are transported by a licensed hazardous waste contractor to specialized, out-of-state disposal facilities that meet strict environmental safety standards.
“This program provides safe and environmentally responsible disposal of unwanted pesticides for homeowners and family-owned farms,” said Karla Boyd, BPC Policy & Regulations Specialist. "By participating, people are directly protecting our land and water for future generations.”
