Mercury is a metal with many useful properties, so it has been used by people in many different ways. Unfortunately, mercury is also very toxic to people and wildlife, and some of its uses have resulted in widespread contamination of the environment.
The Sacramento Stormwater Quality Partnership has identified mercury as a top priority pollutant.
Be Mercury Free
Be Mercury Free is a regional program dedicated to reducing the amount of mercury entering the Sacramento River watershed. Be Mercury Free strives to educate Sacramento area residents and businesses about the sources, effects, and proper disposal of mercury and how to reduce mercury sources in residential households, schools, hospitals, and industries. Be Mercury Free is supported by various public and private partners.
Mercury Product and Spilled Mercury Disposal
Several commonly used household and business products contain mercury, such as fluorescent light bulbs and batteries. Mercury is toxic to people and to wildlife and these products cannot be disposed of in garbage or recycling containers. These items require special care in disposal to prevent harm to the environment. Contact your local solid waste service provider to determine the best way to dispose of items such as batteries and lightbulbs that contain mercury.
