Problems We Found in Fresno's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Fresno's water quality, we aggregated water quality test data from the City of Fresno Water Division and the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. We cross reference these data with toxicity studies in the scientific and medical literature, and look at upcoming regulatory changes.  The water filters we build for people in Fresno are optimized with this research in mind.

Source Of Fresno Drinking Water

For Fresno residents, there are two sources of drinking water. One is derived from the Fresno Sole Source Aquifer, a large underground water system that supplies many communities in the San Joaquin Valley. The Water Division operates approximately 260 wells that draw from this aquifer. The second source of Fresno's drinking water is surface sourced water from the Sierra Nevada delivered via Fresno Irrigation District and Friant-Kern canals. This water is stored in both Millerton and Pine Flat lakes, located in the foothills east of Fresno. 

Extremely High Levels Of Chromium 6 In Fresno Drinking Water

Fresno's drinking water has one of the higher levels of Chromium 6 among major US cities.  Chromium 6 is a highly toxic metal that is not regulated by the EPA.  In recent years, Fresno tap and drinking water has averaged 2200 parts per trillion for Chromium 6.  For the sake of perspective, these levels are a staggering 110 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Fresno's Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter.  Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. 

Still Have Questions About Fresno Tap Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each customer's water.  The contaminants that we list above are what we consider to be major “points of emphasis” that we use to build water filters that are built specifically for Fresno city water, but our filters provide broad protection against a wide range of contaminants.
