Tap water quality in Pasadena, California? Is it safe to drink?

The tap water quality in Pasadena, California is carefully monitored and managed to meet federal and state safety standards. The local water utility in charge of providing high-quality water to the residents is Pasadena Water and Power.

Key Points about Pasadena's Water Quality:

1. Source: Pasadena's water comes from a combination of surface water and groundwater sources. Surface water is primarily drawn from the Metropolitan Water District of Southern California (MWD), while groundwater is extracted from local aquifers.
2. Testing and Standards: Pasadena Water and Power conducts regular and rigorous testing to ensure that the water meets the standards set by the Environmental Protection Agency (EPA) and the California State Water Resources Control Board. These tests check for contaminants like lead, nitrates, and other potential pollutants.
3. Water Hardness: The water in Pasadena is categorized as moderately hard because it contains minerals like calcium and magnesium. Those minerals can accumulate in plumbing fixtures over time, causing scale buildup and reducing the efficiency of water heaters and other appliances.
4. Common Concerns: Some residents report issues with the taste and odor of the water, which can be attributed to the mineral content and chlorine used for disinfection. Additionally, there are occasional concerns about contaminants like lead and pesticides, although levels typically remain below the regulatory limits. Using water filters can help mitigate these concerns and improve the overall taste and quality of tap water.

Despite meeting safety and quality standards, some residents may prefer using water purifiers and water softeners to enhance their water experience. This can help reduce mineral content, improve taste, and provide additional protection against potential contaminants.
