How Safe and Clean is your water? Our Water Quality Lab just got a perfect score!

As the primary wholesale water supplier in Santa Clara County, Valley Water is dedicated to assuring a reliable supply of safe, clean drinking water to our community.

In support of this mission, Valley Water is home to a sophisticated laboratory dedicated to the safety of our tap water, source water and groundwater. Since 2008, the Water Quality Lab has been housed in a new, state-of-the-art building designed to maintain the specialized test equipment used to meet increased water-quality testing needs and respond to emerging contaminants and more stringent water quality standards. The rigorous testing performed by the lab ensures that the treated water we deliver consistently meets or exceeds all applicable water quality regulatory standards.

Our Water Quality Lab tests water from our water treatment plants, reservoirs, groundwater basin, and recycled water.

The Water Quality Lab recently completed its annual performance evaluation and achieved a remarkable 100% passing score! This was a single-blind study based on samples of unknown concentrations for a wide variety of chemical and microbiological analyses and involved a total of 321 different parameters.

This study is annually required by the state of California’s Environmental Laboratory Accreditation Program (ELAP). Together with ELAP’s on-site audits of the Water Quality Lab’s quality management system and analytical performance, this milestone allows our Lab to maintain accreditation for the main Lab and a small laboratory located at the Silicon Valley Advanced Water Purification Center.

And this achievement highlights the outstanding work performed by our team of chemists, microbiologists and support staff to ensure Santa Clara County residents have safe and clean drinking water.

  1. SO hard water does not enter into the testing process. Lime and calcium are still evident even with anti-scale filtering.
    Anderson Dam is not broken, Fixing has more to do with pleasing the worries of ridiculous builders and buyers of homes built directly in front of the dam in what used to be orchards.
