November 2026: Hazardous Waste Collection Event Scheduled for April 19 at Fairgrounds

Boulder County residents can safely dispose of household hazardous waste including paint, solvents, pesticides, batteries, and electronics at a free collection event on Saturday, April 19 at the Boulder County Fairgrounds. No appointment is necessary. Commercial waste is not accepted.

The Walden Ponds open space property encompasses 389 acres and features 13 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $260,000, making it one of the largest collaborative efforts in the county’s history.
