Water Quality Reports

The Santa Clara Valley Water District's water quality laboratory is responsible for ensuring that the drinking water that the district provides is of the highest possible quality, meeting or exceeding all federal and state drinking water standards.
The laboratory accomplishes this by performing a range of analytic services on both untreated (source) and treated water, including organic, inorganic and microbiological analysis. The laboratory's water quality professionals perform water quality compliance and operational control monitoring, using methodology approved by the Environmental Protection Agency and state-of-the-art instrumentation.
The monthly water quality report shows the quality of source (untreated) water at each of the district's three water treatment plants, and the treated water which the district delivers to water retailers in Santa Clara Valley.
