Problems We Found With Santa Ana Drinking Water


Emma Schultz, M.S. | Scientific Contributor   

For our Santa Ana water quality report, we aggregated we aggregated contaminant data from the City of Santa Ana’s Water Resources Division, the water provider for Santa Ana, 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 that we sell in Santa Ana are optimized with these issues in mind.

Source of Santa Ana Drinking Water

Santa Ana tap water is a blend of 70% groundwater and 30% imported water. Water is imported via the Metropolitan Water District of Southern California from the Colorado River via Lake Havasu and snowpack runoff from Northern California’s Sierra Nevadas. All imported water is treated in Yorba Linda or La Verne before delivery to Santa Ana. Local groundwater is pumped to the surface from 20 city-owned wells.

Arsenic Contamination In Santa Ana Tap Water

Arsenic is a toxic heavy metal that is known to cause cancer, as well as other adverse health effects. Arsenic originates in the source water itself.  While Santa Ana is in compliance with EPA water quality standards, it is important to understand that the EPA standard balances toxicity against the costs of removing arsenic from drinking water. The most recent tap water quality report for Santa Ana reported average arsenic concentrations of less than 2 parts per billion for groundwater, and 2.3 ppb for imported surface water.  We recommend that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children.  

High Levels Of Chromium 6 In Santa Ana Drinking Water

Chromium 6 is a highly toxic metal not currently regulated by the EPA.  Santa Ana tap water has recently averaged 780 parts per trillion for chromium 6.  These levels are nearly 38 times higher than the concentration determined to have a negligible impact on cancer risk.  For this reason, we recommend that Santa Ana residents take steps to remove chromium 6 from drinking water.  

Disinfection Byproduct (DBP) Levels In Santa Ana Drinking Water

DBPs are emerging contaminants that form when chlorine-based disinfectants are added to water and then combine with naturally-occurring organic matter found in the water supply.  While these chemicals are not yet well-regulated, the EPA has cautioned that ingesting high levels of disinfection byproducts have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. Santa Ana’s tap water has recently had moderate levels of trihalomethanes, with an average of 37 ppb (and a maximum of 51.2 ppb), and has measured low levels of haloacetic acids as well.

Chlorine Levels In Santa Ana Drinking Water

Like most municipalities in the United States, Santa Ana adds chlorine to the water supply to protect against waterborne illness. While not considered harmful to public health, many consumers find that removing chlorine from their drinking water greatly improves the overall taste and odor.  When your tap water is filtered, we expect that you will notice an immediate taste improvement.  

Still Have Questions About Santa Ana Tap Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each city’s water.  The contaminants that we list above are what we consider to be “points of emphasis” to address in our filter design, so we can design and build the best water filter for Santa Ana tap water, but all of our water filters provide broad protection against other contaminants commonly found in drinking water (e.g. VOCs, heavy metals (including lead), pharmaceuticals, solvents, pesticides, mercury).
