The Solution to Pollution

The ONLY legal way to dispose of hazardous and toxic materials and products is through a Household Hazardous Wastes (HHW) program.

Hazardous waste generated by residents and businesses can reach our waterways through illegal dumping, runoff, sewer spills, storm drains, and landfills, and pollutes our local water environment.


to all Pleasant Hill residents, the Household Hazardous Waste Collection Facility helps reduce this pollution through reuse, recycling, and proper disposal of hazardous waste. Nominal processing fee for small businesses.
