**Updated July 2021 to include most recent water quality info

For Hydroviv’s city of Glendale water quality assessment, we aggregated water quality test data from City of Glendale Water and Power, the city’s water provider, 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 scientific and medical literature, and look at upcoming regulatory changes. The water filters that we build for people who live in Glendale are optimized with these figures in mind.

Source Of Glendale Drinking Water

In 2016, 65% of Glendale’s water was purchased from the Metropolitan Water District, after being imported and treated from Northern California and the Colorado River. The remaining 35% comes from local groundwater sources extracted from the Verdugo and San Fernando Basins. In addition, 7% of total water used in 2016 was recycled water delivered by the Los Angeles-Glendale Water Reclamation Plant, though this water is only used for irrigation and industrial purposes.

Arsenic In Glendale Drinking Water

Arsenic is a toxic heavy metal that is known to cause cancer and other health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. While the city of Glendale's water quality is in compliance with EPA water quality standards, it’s important to point out that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. The most recent City of Glendale water report revealed that the water from the Jensen plant had average arsenic levels of 3.1 parts per billion, while the Glendale Treatment Plant had up to 1.6 parts per billion. We recommend that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if there are children in the home.

Extremely High Chromium 6 Levels In Glendale Drinking Water

Chromium 6 is a highly toxic metal that is not currently regulated by the EPA, and is only loosely regulated at the state level. In the most recent water quality data, the Glendale Treatment Plant averaged 5300 parts per trillion of chromium 6, with a maximum measured concentration of 6400 parts per trillion. To put it in perspective, these levels are 265 and 320 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Glendale 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 high levels of disinfection byproducts in drinking water are are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

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 Glendale, but our filters provide broad protection against a wide range of contaminants found in Glendale's tap water, including VOCs, pesticides, lead, and mercury.

**Updated June 11, 2021 to include current data

Hydroviv’s Water Nerds have updated our assessment of Huntington Beach water to include the most current available data. We look at information from quality test data from the Huntington Beach Utilities Division, 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 scientific and medical literature, and look at upcoming regulatory changes. The water filters that we build for users in Huntington Beach are optimized with these data in mind. 

Source Of Huntington Beach Drinking Water

Huntington Beach drinking water is a blend of groundwater provided by Orange County Water District, water imported from Northern California, and water from the Colorado River by the Municipal Water District of Orange County (MWDOC). 77% of Huntington Beach water comes from groundwater sources, and 23% is imported surface water from the Colorado River. Groundwater comes from a natural underground aquifer that is replenished with water from the Santa Ana River, local rainfall, Orange County Water District’s Groundwater Replenishment System, and imported water. The groundwater basin is 350 square miles and lies beneath north and central Orange County from Irvine to the Los Angeles County border and from Yorba Linda to the Pacific Ocean.

The State of California last performed a Source Water Assessment in 2002, and they found that the surface water sources are most vulnerable to runoff from increased urbanization and other types of runoff. The groundwater sources are considered most vulnerable to pollution from: dry cleaners, electrical/electronic manufacturing, gas stations, known contaminant plumes, metal plating, finishing, or fabricating, military installations and plastics/synthetics producers.

Arsenic In Huntington Beach Drinking Water

Arsenic is a toxic heavy metal that is known to cause cancer and other health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. While Huntington Beach is in compliance with EPA water quality standards, it’s important to point out that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. The most recent tap water quality report for Huntington Beach reported an average arsenic concentration up to 2 parts per billion. We strongly 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 Huntington Beach Drinking Water

Chromium 6 is a highly toxic metal that is not currently regulated by the EPA. In recent years, Huntington Beach tap water has averaged 105 parts per trillion for Chromium 6. To put it in perspective, these levels are 5 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Huntington Beach 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 on disinfection byproducts 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.

Chlorine and Chloramine In Huntington Beach Drinking Water

Like many other municipalities in the United States, Huntington Beach treats its water with chlorine to protect against waterborne illness. Huntington Beach also imports water from MWDOC, which disinfects the water with chloramines. While these two disinfectants are not typically considered to be harmful on its own (unless you are a dialysis patient), many people find that removing chlorine and chloramine from drinking water greatly improves its taste and odor.

What Do I Need To Know About Arsenic In My Drinking Water

How Do I Remove Chromium 6 Contamination From My Drinking

Water? Disinfection Byproducts In Your Drinking Water

Kezia Snipe  |  Hydroviv Research Analyst

For Hydroviv’s assessment of Pasadena's city water quality, we aggregated water quality test data from Pasadena Water and Power, the city’s water provider 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 delve into upcoming regulatory changes. The water filters that we offer at Hydroviv are optimized with these numbers in mind.

Sources Of Pasadena Drinking Water

In 2016, PWP produced 26,890 acre-feet or 8.8 billion gallons of water, to serve approximately 166,000 consumers in Pasadena, portions of the unincorporated areas of Altadena, East Pasadena, and San Gabriel. During the year, nearly 40 percent of the water supply was pumped from local groundwater, whereas 60 percent came from imported surface water purchased from the Metropolitan Water District (MWD). Less than 1 percent was purchased from neighboring water agencies that combine surface water and groundwater.

Lead In Pasadena Drinking Water

Lead enters Pasadena's city water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Currently,10% of samples analyzed for lead in Pasadena are 1.7 parts per billion. Though in compliance with federal regulations, EPA and CDC both acknowledge that there is no safe level of lead, and federal regulations do not take into account levels measured at an individual tap. The American Academy of Pediatrics recommends that any taps used to serve children have lead levels no higher than 1 part per billion.

Very High Chromium 6 Levels In Pasadena Drinking Water

Pasadena's water quality was reported with very high levels of Chromium 6. Chromium 6 is a highly toxic metal that is not currently regulated by the EPA. In recent years, the city’s tap water has averaged a concerning 1900 parts per trillion for Chromium 6. For a bit of perspective, these levels are 95 times HIGHER than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Pasadena 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.

How Do I Remove Chromium 6 Contamination From My Drinking Water?
Disinfection Byproducts In Your Drinking Water

Emma Schultz, M.S. | Scientific Contributor   
**Updated August 6, 2019 to include current data

We've aggregated the most current water quality test data from Riverside Public Utilities, the U.S. Environmental Protection Agency (EPA). We then cross reference these data with toxicity studies in scientific and medical literature, and supplementary internal data. The water filters that we sell in Riverside are optimized to remove detected contaminants.

Source Of Riverside Drinking Water

Riverside gets its drinking water entirely from groundwater sources. Water is pumped from the Bunker Hill and Riverside groundwater basins and is treated before being distributed to Riverside residents. It should be noted that “these sources are considered most vulnerable to historical contamination from industrial and agricultural operations” (see above link to the 2018 Water Quality Report).

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 2200 parts per trillion for chromium 6. For reference, these levels are nearly 110 times higher than the concentration determined to have a negligible impact on cancer risk. For a bit of context, the state of California tried to set a state Maximum Contaminant Level (MCL) of 20 parts per trillion for chromium 6. After municipalities were unable to comply with the interim MCL, a lawsuit resulted in the withdrawal of the 20 parts per trillion standard. 

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 1 parts per billion, with a maximum concentration of 2.9 parts per billion. 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 Riverside's 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. EPA, CDC, and American Academy of Pediatrics all acknowledge that there is no safe level of lead for children. In addition, federal regulations cannot take into account levels measured at an individual tap.  

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.

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 Riverside's 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).

Updated May 28, 2021 to include most recent water quality data

Our Water Nerds analyze data from the City of Stockton to better understand present contaminants in your tap water.We also use data from the U.S. Environmental Protection Agency (EPA), toxicity studies, scientific and medical literature, as well as from samples that we collect and analyze. The undersink water filters that we build and 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 City Stockton's water 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's drinking water has detectable levels of arsenic in the drinking water, on average 3.6 parts per billion according to 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 and drinking 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.

Hydroviv is a water filtration company that uses water quality data to optimize whole house water purifiers 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.
