Problems We Found With Riverside Drinking Water

Emma Schultz, M.S. | Scientific Contributor   

For our assessment of Riverside tap water, we aggregated water quality test data from Riverside Public Utilities, the water provider for Riverside, 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 Riverside are optimized with these issues in mind.

Source Of Riverside Drinking Water

Riverside tap water is groundwater-sourced. Water is pumped from the Bunker Hill and Riverside groundwater basins. It should be noted that “these sources are considered most vulnerable to historical contamination from industrial and agricultural operations” (see above link to Water Quality Report 2014).

Arsenic In Riverside Drinking Water

Arsenic is a cancer-causing toxic heavy metal, that can also lead to other adverse health effects. Arsenic originates in the source water.  While Riverside is in compliance with EPA water quality standards, it should be understood that EPA’s standard balances toxicity against the costs of removing arsenic from drinking water. Riverside’s most recent tap water quality report listed average arsenic concentrations of less than 2 parts per billion, with a maximum of 3.5 ppb.  We strongly recommend that tap water with more than 1 part per billion be treated to remove arsenic, particularly if there are children in the home.  

Lead In Riverside Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as what recently happened in Flint, Michigan), lead leaches into drinking water, and can reach unsafe levels.  Recent analysis for lead in Riverside found 90th percentile concentraions of 5 parts per billion.  While the city is currently in compliance with federal regulations, EPA and CDC acknowledge that there is no safe level of lead. In addition, federal regulations cannot take into account levels measured at an individual tap.  

High Levels Of Chromium 6 In Riverside Drinking Water

Chromium 6 is a highly toxic metal not currently regulated by the EPA.  Riverside tap water has recently averaged a substantial 800 parts per trillion for chromium 6.  For reference, these levels are nearly 39 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Riverside Drinking Water

DBPs are halogenated emerging contaminants that occur when chlorine-based disinfectants are added to the water supply and then combine with naturally-occurring organic matter.  Although these chemicals are not yet well-regulated, EPA has stated that they have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. Riverside’s tap water has recently had high levels of DBPs, with an average of 100 ppb.

Use Of Chlorine In Riverside Tap Water

As is common practice in the United States, Riverside adds chlorine to its water to protect consumers against waterborne illness. While not considered harmful per se, many people 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 improvement in taste.  


Still Have Questions About Riverside's Tap Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each city’s water.  The chemicals that we list above are what we consider to be “points of emphasis” so we can build the best water filter for Riverside 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).

If you’re interested in learning more about water filters that have been optimized for Riverside tap water, feel free to visit www.hydroviv.com, reach out by email (hello@hydroviv.com) or through our live chat.  We also frequently post water-related news on Twitter or Facebook.
