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.

Water quality monitoring at 8 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2025. The Parks & Open Space publishes quarterly water quality reports on the Boulder County website.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $355,000, making it one of the largest collaborative efforts in the county’s history.

Community Impact

Wildfire risk mapping conducted by Wildfire Partners shows that 35% of properties in the Louisville area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Louisville and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

Next Steps

Volunteers contributed over 12,688 hours to this program last year. The Parks & Open Space coordinates with 7 nonprofit partner organizations throughout Boulder County to deliver services.

Data from the 2025 Boulder County Community Survey shows that 81% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 4,975 responses from residents across the county.
