Key California Drinking Water Regulations
California’s laws make sure your water is safe to drink by setting clear rules on water quality, testing, and contamination limits. The state lists what contaminants are allowed, how often to test, and what to do if problems come up.
California Safe Drinking Water Act
This act sets the foundation for safe drinking water in California. It requires your local water supplier to meet strict safety standards.
The law gives the California Department of Public Health the power to enforce these rules. Water systems must test your water regularly and report the results.
If contaminants go over allowed limits, they must tell you and fix the problem quickly. The act keeps your drinking water clean and requires water providers to stay transparent about water quality issues.
Maximum Contaminant Levels
The state sets Maximum Contaminant Levels (MCLs). These are the highest amounts of substances allowed in drinking water without harming your health.
Examples include bacteria, lead, pesticides, and minerals. An MCL is based on health studies to keep long-term exposure safe.
Your water supplier tests for these regularly. If levels go over the MCL, they must reduce contamination or warn consumers.
Important facts about MCLs:
- They apply to drinking water systems throughout California.
- They cover harmful chemicals, metals, and microorganisms.
- Water providers must meet MCLs at all times.
Monitoring and Compliance Requirements
California requires frequent testing to keep your water safe. Water suppliers test sources and distribution systems for contaminants like bacteria, chemicals, and metals.
Certified labs must do these tests using state-approved methods. Most systems test several times a year.
If a test shows contamination, your water provider must fix it and notify you. They send reports to state agencies to prove they follow the rules.
This monitoring helps catch problems early and keeps your home’s tap water safe.
Federal vs. State Standards
Drinking water standards in California follow federal rules but also include stricter state rules. These rules regulate contaminants and testing requirements to help make sure your water is safe to drink.
Comparison With EPA Regulations
The Environmental Protection Agency (EPA) sets federal rules for drinking water under the Safe Drinking Water Act. These rules include limits on over 90 contaminants like lead, bacteria, and chemicals.
California follows EPA rules, but some local water systems do extra testing to meet local needs. Water suppliers must test your water regularly and report the results.
EPA standards provide a strong foundation. California water providers often add rules to handle local risks better.
Unique California Requirements
California has its own rules that go beyond federal ones. The state sets stricter limits for some contaminants, such as chromium-6, which the EPA has not fully regulated.
California may require more frequent testing or extra treatment steps, especially in areas with known pollution risks. For example, the state demands special nitrate testing in farm regions.
California enforces public notification laws. You get clear information if your water does not meet these standards.
Contaminants Regulated in California
You need to know what kinds of contaminants are controlled in California's drinking water. These include bacteria, chemicals, radioactive materials, and new substances that may pose risks.

Microbial contaminants are tiny organisms like bacteria, viruses, and parasites. These can cause illnesses if they enter your drinking water.
California monitors microbes such as E. coli and Giardia, which can come from sewage or animal waste. Water systems use treatment methods like chlorination and filtration to kill or remove these microbes.
Regular testing helps detect microbial contamination quickly. If microbes are found, water providers fix the problem and alert the public.
Chemical Contaminants
Chemical contaminants come from natural sources, farming, industry, or household waste. California regulates many types, including:
- Lead and copper from old pipes
- Nitrates from fertilizers
- Pesticides used on crops
- Volatile organic compounds (VOCs) from chemicals like solvents
These chemicals can cause health problems, especially over time. The state sets maximum levels to keep you safe.
Water suppliers must test for these chemicals regularly. If levels go too high, they must act to reduce contamination and notify you.
Radiological Contaminants
Radiological contaminants are radioactive elements like radium, uranium, and iodine. These come from soil and rocks but can enter your water supply.
Long-term exposure to radiation in water can increase cancer risk and other health effects. California keeps strict limits to keep these contaminants well below harmful levels.
Water providers test for radiological contaminants. If levels go over the limit, they use treatment or alternative water sources.
Emerging Contaminant Concerns
New chemicals and substances are being found in water more often. These "emerging contaminants" include pharmaceuticals, personal care products, and per- and polyfluoroalkyl substances (PFAS).
California works to understand how these affect health and sets rules for monitoring them. Some may build up in the body or the environment, so early detection is important.
Water systems may test for these less common contaminants and start new treatment methods to reduce risks. Staying informed helps you protect your drinking water.
