Household Hazardous Waste Program

Our Guide to Safe Hazardous Waste Disposal

Believe it or not...your home is probably full of hazardous waste. Many products we use regularly everyday (cleaners, glues, soaps, pesticides, pharmaceuticals) are toxic or hazardous. If these products are used improperly, carelessly, or in a manner not intended, they can injure you both directly and indirectly. By putting these into your trash can, you endanger refuse collectors, the environment and our drinking water. You are ultimately liable for these wastes and any harm they cause.

Hazardous Waste Collection Centers

The permanent collection facility is located at County Center IV, 1710 Morgan Road, Modesto. Household Hazardous Waste are collected free of charge to the residents of Stanislaus County.

The collection facility is open Friday and Saturday 8 am to 12 pm, excluding major holidays.

Safe Mercury Disposal

Stanislaus County residents who drop off a mercury-containing thermostat and/or thermometer at the Permanent Household Hazardous Waste Collection Facility in Modesto or at one of the County's upcoming mobile collection events can now receive a $5 gift card to Home Depot provided by Covanta Energy. By recycling the old mercury-containing thermostats and thermometers, residents can do their part to protect the environment by making sure these kinds of products don't end up in the trash. Mercury is a heavy metal that can present risks to human health and the environment unless it is properly handled and disposed of.

Residents who replace their old thermostats with digital units can also save money on their energy bills. According to the U.S. Department of Energy, installing a new programmable, mercury-free digital thermostat can help cut a home's energy cost by 15-20%.
