Problems We Found In Orange's Tap Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Orange's tap water, we aggregated water quality test data from the City of Orange Water Division, 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 Orange are optimized with these figures in mind.

Source Of Orange Drinking Water

Orange’s water comes from three sources. The primary source is groundwater drawn from 14 municipal wells drilled about 1000 feet into the Santa Ana River Aquifer. Well water goes directly into the distribution system, is disinfected with chlorine and meets all state regulations. The second source is water imported by the Metropolitan Water District, from the Colorado River and from northern California (San Francisco-San Joaquin Bay Delta). Metropolitan water is filtered and disinfected with chloramines. Orange also purchases a small amount of water from the Serrano Water District. This source is primarily treated surface water, but also includes local treated well water.

Chromium 6 Levels In Orange Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA.  In recent years, Orange’s tap water has averaged 320 parts per trillion for Chromium 6.  While they are in compliance with nonexistent federal and very loose state regulations, these levels are 16 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Orange 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. 

Still Have Questions About Orange 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 Orange, but our filters provide broad protection against a wide range of additional contaminants found in Orange's tap water.

If you’re interested in learning more about water filters that have been optimized for Orange's water, or just have questions about water quality in general, 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.  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).

Problems We Found In Irvine, California Drinking Water

Emma Schultz, M.S. | Scientific Contributor   
Updated July 19, 2019 to include current data

Our Water Nerds have updated our assessment of Irvine drinking water to include the most recent available data. We used information from the Irvine Ranch Water District, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. Our team then cross references these  water data with toxicity studies in the scientific and medical literature, and look at upcoming regulatory changes. The water filters that we sell in Irvine are optimized with these issues in mind.

Source Of Irvine Drinking Water

Irvine's drinking and tap water is a mix of groundwater - and imported surface water-based. 65% of the water supply is groundwater that comes from the Orange County Groundwater Basin. Additional groundwater is also obtained from the Cleveland National Forest from the Harding Canyon Dam watershed, the State Water Project and the Colorado River. 

Arsenic In Irvine Drinking Water

Arsenic is a toxic heavy metal that can cause cancer and other health problems. Arsenic originates naturally in source water. Although Irvine's water quality is in compliance with EPA water quality standards, consumers should know that the U.S. EPA's standard balances toxicity against the costs of removing arsenic from drinking water. Irvine’s most recent tap water quality report listed a highest level detected of 3.6 parts per billion, with a local treated groundwater average of less than 2 ppb.  We strongly suggest that tap water with more than 1 part per billion be treated to remove arsenic, especially in homes with children.  

Lead In Irvine Drinking Water

Lead enters into a consumer’s tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as recently happened in Flint, Michigan), lead leaches into the drinking water and can reach hazardous levels. Recent analysis for lead in Irvine's tap water found a 90th percentile concentration of less than 5 parts per billion. While the Action Level is 15 parts per billion, the EPACDC and American Academy of Pediatrics all recognize that there is no such thing as a safe level of lead. Of course, federal regulations cannot take into account levels measured at an individual tap.

Chromium 6 In Irvine Drinking Water

Chromium 6 is a highly toxic metal that, while monitored, is not regulated by the EPA. Irvine’s tap water recently averaged 240 parts per trillion for chromium 6, with samples ranging up to 720 ppt. Average levels are 12 times higher (with the upper range 36 times higher) than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Irvine Drinking Water

DBPs are a category of emerging contaminants that are created when chlorine-based disinfectants added to the water supply combine with naturally-occurring organic matter. Although these chemicals are not fully regulated, the EPA has explicitly stated that they are linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. Irvine’s tap water had a 2016 average tested across twelve locations of 57 parts per billion, ranging as high as 58 ppb. This is well within the Maximum Contaminant Levels for Total Trihalomethanes and Haloacetic Acids.

Use Of Chloramine In Irvine Tap Water

While many cities use chlorine as the primary disinfectant, Irvine’s water is disinfected with chloramine, made by combining chlorine and ammonia. Chloramine is the frequent problem when customers report a “bad taste” in their tap water, and unlike chlorine will not fade away if left in the fridge overnight. The recent chloramine residual for Irvine was 1.9 parts per million, with samples ranging as high as 11 ppm; while not a violation, this amount exceeds the maximum residual disinfectant level of 4.0 ppm. Most one-size-fits-all water filters use filtration media that don’t adequately remove chloramine, but the filters that Hydroviv builds for Irvine use special filtration media that are purpose-built to remove chloramine as well.

Still Have Questions About Irvine’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 Irvine 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).

Problems We Found In Fullerton, California Drinking Water

Kezia Snipe | Hydroviv Research Analyst
Updated August 16, 2019 to include current data

We've updated our water quality report of Fullerton, California to include the most up-to-date information. Our team aggregated data from the City of Fullerton Water System Management, the U.S. Environmental Protection Agency (EPA), as well our own internal data. We cross reference these data with toxicity studies in scientific and medical literature, and look at upcoming regulatory changes. The water filters that we sell to our customers in Fullerton are optimized with this research in mind. 

Source Of Fullerton Drinking Water

Fullerton source water is a mix of both surface and groundwater. Surface water  is imported by the Metropolitan Water District of Southern California (MWD), which is a blend of the State Water Project and the Colorado River Aqueduct. The groundwater that Fullerton uses comes from a reservoir under the Prado Dam. 

Lead In Fullerton Drinking Water

Lead enters tap 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. A 90th percentile was not detected in Fullerton drinking water, but older homes built before 1986 still contain lead pipes and plumbing. The EPACDC and The American Academy of Pediatrics all  acknowledge that there is no safe level of lead for children.

Chromium 6 In Fullerton Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Fullerton tap water quality averaged 340 parts per trillion. For the sake of perspective, these levels are nearly 17 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Fullerton 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.

Problems We Found With Sacramento's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

***Updated to include 2019 water quality data***

For Hydroviv’s assessment of Sacramento drinking water, we analyzed the most recent water quality test data from the Sacramento Suburban Water District, the U.S. Environmental Protection Agency (EPA), as well as samples that we collect and analyze. Our Water Nerds then research scientific and medical literature to help determine susceptibilities in your water. The water filters we build for people in Sacramento are optimized to remove the following contaminants.

Source Of Sacramento Drinking Water

Sacramento is split into four service areas: (1) Arden Park Vista, Northgate, and Southwest Tract, (2) Hood, East Walnut Grove, and Delta Estates (3) Laguna, Vineyard, Country Creek Estates, and Grantline (4) Mather, Sunrise, and Anatolia. All four of these sources draw water from local groundwater wells, as well as supplementary surface water treated by the San Juan Water District (SJWD) and the City of Sacramento. Click here if you'd like more information on where your water comes from. 

Arsenic In Sacramento Drinking Water

Arsenic is a toxic metal that is known to cause cancer and other adverse health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. The levels in Sacramento While the average arsenic concentrations are low in Sacramento, there were groundwater samples that reached 4 parts per billion. Arsenic levels in Sacramento range from 3.7 to 9.9 parts per billion. These levels are extremely close to the federal standard of 10 parts per billion, which takes into account the cost of removing arsenic from municipal systems. This means that the 10 part per billion threshold does not fully take into account public health . 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.  

Extremely High Levels Of Chromium 6 In Sacramento Drinking Water

Sacramento's drinking and tap water has some of the highest levels of chromium 6 among major US cities. Chromium 6 is a highly toxic metal that is not currently regulated by the EPA. In recent years, Sacramento tap water has averaged around 4000 parts per trillion for Chromium 6 (in all four service areas), with concentrations reaching over 8000 parts per trillion. For the sake of perspective, the average levels are a staggering 200 times HIGHER than the concentration determined to have negligible impact on cancer risk

Lead Levels In Sacramento Tap Water

Lead enters into a Sacramento consumer’s drinking and tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as recently happened in Flint, Michigan), lead leaches into the drinking water and can reach toxic levels. Recent sampling for lead in Atlanta found that roughly 10% of samples were above 7.8 parts per billion. While the regulatory limit is 15 ppb, both the EPA and CDC recognize that there is no such thing as a safe level of lead. 

Disinfection Byproducts (DBPs) Levels In Sacramento'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.

Problems We Found In Oakland, California Drinking Water

Analies Dyjak, M.A. | Hydroviv Research Analyst
Updated August 5, 2019 to include current data

For Hydroviv’s assessment of Oakland, California drinking water, our Water Nerds aggregate data from various sources. In this report, we've assessed the most recent available data provided by the East Bay Municipal Utility District, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. Our team then cross reference these data with toxicity studies in scientific and medical literature. The water filters that we build and sell at Hydroviv are optimized to removed contaminants in Oakland tap water. 

Source Of Oakland Drinking Water

The city of Oakland gets its water from the Mokelimne River Watershed, which is at the foothills of the Sierra Nevada mountain range. The remaining water is supplied by the East Bay Watershed. 

Lead In Oakland Drinking Water

Lead enters tap 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), lead drains into the drinking water, and can reach dangerous levels. Currently, the 90th percentile for lead in Oakland drinking water is 2.4 parts per billion. Though Oakland's water quality is within compliance with federal regulations, the EPACDC, and The American Academy of Pediatrics all acknowledged that there is no safe level of lead, and federal regulations do not take into account levels measured at an individual tap.

Chromium 6 In Oakland Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Oakland's tap water quality averaged 50 parts per trillion. For the sake of perspective, these levels are nearly 3 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Oakland 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.

Problems We Found in Glendale's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

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. 

Still Have Questions About Glendale 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 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.
