Water Quality

One of the most critical aspects of SGCWD’s mission is to provide safe and clean drinking water each and every day. The District provides water to approximately 50,000 people in the service area through roughly 9,300 service connections. All of the water the District supplies is pumped from wells in the Main San Gabriel and Raymond groundwater basins.

SGCWD produces Water Quality Reports, also known as Consumer Confidence Reports, annually. The reports contain vital information about your drinking water, including data from nearly 1,000 tests conducted throughout the year and details about how the District meets state and federal regulations. Below are links to current and previous Consumer Confidence Reports, which are published by July 1 each year.
