Hazardous Waste & Disposal
Follow proper procedure for disposal of hazardous waste
Motor oil can be recycled curbside
Average household stores 3-10 gallons of hazardous waste
Household hazardous waste should NEVER be placed in garbage, recycling, or yard waste carts. U.S. households generate more than 2 million tons of hazardous waste each year. The average household stores from 3 to 10 gallons of hazardous waste.
Although most of the products' labels listed here do not usually contain the word "hazardous", they are just as hazardous as any industrial waste. Potential hazardous chemicals in these products can be:
Toxic: poisonous or lethal when ingested, touched or inhaled even in small quantities (rat poison, cleaning fluids, pesticides, bleach)
Flammable: easily ignites (lighter fluid, spot and paint removers)
Corrosive: eats away materials and living tissue by chemical action (oven and toilet bowl cleaners)
Reactive: creates an explosion or produces deadly vapors (bleach mixed with ammonia cleaners)
Careless use and disposal of these substances contaminate our food, soil, water, and air; and seriously threaten the ecosystems on which we depend.
Household hazardous wastes (HHW) should never be thrown into the trash or washed down the household or storm drains. Hazardous chemicals can "pass through" treatment processes or storm drains and get discharged into the environment. This occurs because wastewater treatment plants are not designed to remove hazardous chemicals from wastewater, and storm drains flow directly to the Bay without any treatment at all. HHW thrown into the garbage can injure workers during collection or mix with other chemicals when landfilled. Groundwater used for drinking or irrigation can be contaminated when waste products are poured onto or seep into the ground. Follow this link for proper HHW disposal.
All hazardous wastes, including solvents, cleaners and pesticides, can be taken to the Central Contra Costa Sanitary District's facility at 4797 Imhoff Place, Martinez. Call 1-800-646-1431 for information and hours or visit the district's website at www.centralsan.org.

Central Contra Costa Sanitary District
The Central Contra Costa Sanitary District (CCCSD), in partnership with Mt. View Sanitary District, opened a permanent Household Hazardous Waste (HHW) Collection Facility October 25, 1997. The facility is located adjacent to the CCCSD's wastewater treatment plant at 4797 Imhoff Place in Martinez. All Central Contra Costa County residents are eligible to use the facility at no charge.

Collected products that can be reused are given away at no charge to residents and businesses through an innovative waste exchange program.
