The State oversees large water systems that provide drinking water for most of the public. The Small Drinking Water Systems Program makes sure that small systems provide safe drinking water in adequate supply and delivered under adequate pressure.
A small water system is a system that serves water to 25-200 persons daily for at least 60 days out of a year. These systems are usually found in rural ares.
County Services
Staff enforce the California Safe Drinking Water Act (SDWA) which regulates water quality, operator qualifications, maintenance, and systems design. They perform the following functions:
- inspect water sources, treatment and distribution facilities.
- review test results to determine the presence of bacteria in small water systems. If any bacteria is found, staff notify water system operators of actions they must take.
- respond to complaints about poor water quality, contamination or suspected waterborne illness. In the event of an illness confirmed by a physician or a disaster, staff can implement emergency actions.
- issue permits for water suppliers. Staff review and approve permit applications to make sure the system has the equipment, staff and resources it needs.
- advise system operators on how to comply with regulations. Staff help water companies develop their own inspection and testing programs.
- revoke operating permits or work with district/city attorneys to prosecute operators who refuse to comply with regulations.
- supervise construction, rebuilding and destruction of water wells. Staff approve development of new sources of drinking water.
- review and approve changes of ownership of water systems. Staff assist water companies to apply for loans under the State Revolving Fund Program.
Public Concerns
If you are concerned about the quality of your water, your local supplier is required by law to give you information at your request.
If you are not satisfied after reviewing water company data, you can hire a local state certified laboratory to analyze your tap water. The lab will give you sample containers and collection procedures. You can test for bacteria, iron, lead and copper or other contaminants.
Environmental Health does not routinely sample individual resident's water supply.
SEDIMENT COMING FROM TAP WATER
If sediment is coming from out of your hot water line, it is probably caused by rust in your water heater or your plumbing. It is not dangerous to your health. You can correct it by flushing or repairing your water heater or pipes.
If sediment is coming out of your cold water line, it is probably caused by rust in the distribution mains in the street. It can happen when water mains are shaken due to earthquakes or when heavy equipment is used near the mains. The fire department can also cause sediment to break loose by opening hydrants, causing the mains to shake. It is not a health hazard. The sediment should gradually dissipate and disappear.
CAN WATER MAKE ME SICK?
Not likely. Outbreaks of waterborne disease are very rare. Public water systems must routinely test their water quality. If there are signs of contamination, the system is required by law to notify the public immediately.
If you become ill and you don't know why, contact your physician. Your doctor is required to report certain illnesses to the Health Department. Environmental Health can investigate water systems and put emergency safety procedures into effect, if necessary.
