Problems We Found In Drinking Water In Stockton
Kezia Snipe | Research Analyst
For Hydroviv’s assessment of Stockton’s tap water, our scientists examined water quality test data from California Water Service, the water utility provider for Stockton, 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 work with our contacts at EPA to understand upcoming regulatory changes. The water filters that we sell to people who live in Stockton are optimized with all of these things in mind.
Source Of Stockton Drinking Water
California Water uses a combination of local groundwater and water purchased from the Stockton East Water District, which is imported from the New Melones and New Hogan Reservoirs. The Stockton system includes 27 active wells, one well being prepared to go online, 17 booster pumps, and 12 storage tanks.
Arsenic In Stockton Drinking Water
Arsenic is a toxic metal that is known to cause cancer and other health issues. Arsenic contamination originates from the source water itself, and is more prominent in areas (like Stockton) that pull water from groundwater sources. Like other municipalities in the same region, Stockton has detectable levels of arsenic in the drinking water, on average 2.2 parts per billion (up to 8 parts per billion) in the most recent data. Because of this, Stockton made the following public disclosure:
"While your drinking water meets the federal and state standards for arsenic, it does contain low levels of arsenic. The arsenic standards balance the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking water. The EPA continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects, such as skin damage and circulatory problems."
We highly recommend that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children.
Chromium 6 In Stockton Drinking Water
Chromium 6 is a toxic metal that is not regulated by the EPA, despite being a common discharge from steel processing plants, tanneries, and metal plating facilities. In recent years, tap water in Stockton has averaged 790 parts per trillion for Chromium 6. For the sake of perspective, these levels are 40 times higher than the concentration determined to have negligible impact on cancer risk by the state of California.
Disinfection Byproducts (DBPs) In Stockton 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 website discloses that exposure to high levels of disinfection byproducts are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.
Still Have Questions About Stockton Tap Water Or Water Quality In General?
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 Stockton, but our filters provide broad protection against a wide range of contaminants found in Stockton's tap water, including lead, VOCs, and pesticides.
If you’re interested in learning more about water filters that have been optimized for Stockton's water, or just have questions about water quality in general, feel free to visit www.hydroviv.com, reach out by email (firstname.lastname@example.org) or through our live chat. We also frequently post water-related news on Twitter or Facebook. We pride ourselves in being a reputable source of information on water quality, and your questions will be answered by scientists, not salespeople (we don't have any salespeople on staff).
