Your Water Quality

Safe Drinking Water Act (SDWA)

Valley County Water District proudly serves the potable water needs and demands of portions of the City of Baldwin Park, the City of Irwindale, the City of West Covina, and the City of Azusa. As a public water agency, Valley County Water District is regulated at the state level by the State Water Resources Control Board (SWRCB) and at the federal level by the United States Environmental Protection Agency (USEPA). In 1974, the United States Congress passed the Safe Drinking Water Act (SDWA) and later amended it in 1996. The drinking water standards imposed by this legislation require Valley County Water District to test for and remove substances detected in the drinking water in quantities as small as 1 part per billion. That’s the equivalent to finding and removing a single drop of a substance in a typical 20,000-gallon swimming pool.

Water Testing

In an effort to remain compliant with all of the state and federal standards, Valley County Water District regularly collects and tests samples of the drinking water being produced and served. Valley County Water District contracts with a third party laboratory to analyze the collected water samples using SWRCB-approved methods. All sample results are reported to SWRCB for compliance monitoring to ensure that the water served by Valley County Water District is safe for you and your family to drink. In addition, Valley County Water District is required to provide an annual Consumer Confidence Report to its customers summarizing the quality of the water served throughout the year.
