Los Angeles-City (LADWP) Water Quality Report

DID YOU KNOW water quality reports, also known as “Consumer Confidence Reports (CCRs),” are annual documents that all public water systems are required to provide to you via mail and online. These reports are supposed to provide important information about the quality of the drinking water delivered over the previous year.

They can be difficult to read or understand. They are often many pages long and contain complex tables and charts. Culligan Water wants to change this and help you MAKE SENSE OF YOUR WATER.

This easy-to-read report will provide you with the following:

1) Infrastructure Improvements: Significant investments were made in water infrastructure, including the commissioning of the Los Angeles Reservoir Ultraviolet Disinfection Plant (LARUVDP), a state-of-the-art water treatment facility costing $123.8 million. This facility marks the completion of a 20-year journey to bring LADWP’s infrastructure into full compliance with U.S. EPA regulations for protecting drinking water in reservoirs.

2) Water Sources and Usage: The report details the sources of Los Angeles’ water in 2022, with 15% coming from the Los Angeles Aqueduct, 73% from purchased imported water, 10% from local groundwater, and 2% from recycled water. It highlights the community’s response to conserve water amidst a severe multi-year drought, noting a significant reduction in water usage compared to the previous year.

3) PFAS: The California State Water Resources Control Board (State Board) has been actively investigating and sampling for PFAS since 2019. Updated drinking water response levels remained 10 parts per trillion for PFOA and 40 parts per trillion for PFOS during the course of the year. Additionally, two other PFAS constituents in the PFAS family have recently been assigned response levels by the Division of Drinking Water. Those chemicals are Perfluorobutane sulfonic acid (PFBS) and Perfluorohexane sulfonic acid (PFHxS).

Violations in this water system that have happened in the last five years. To learn more about the violations visit the source at the EPA Echo site.

These are issues that are often discussed within the region. While some may not meet or exceed health guidelines, many rise above the public health goal.

Unregulated contaminants are of concern because they are not officially governed at a federal level by the EPA. These substances could pose a threat to health and the environment, but there are no standards.
