Problems We Found In Fullerton's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Fullerton, CA tap water quality, we aggregated water test data from City of Fullerton Water System Management, the water provider for the city 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 offer at Hydroviv are optimized with these numbers in mind. 

Source Of Fullerton Drinking Water

Fullerton's drinking water is a blend of county groundwater basin and surface water imported by the Metropolitan Water District of Southern California (MWD). MWD’s imported water sources are a blend of State Water Project water from northern California and water from the Colorado River Aqueduct. Fullerton's groundwater comes from a natural underground reservoir that stretches from the Prado Dam and fans across the northwestern portion of Orange County, excluding the communities of Brea and La Habra, and stretching as far south as the El Toro ‘Y’.

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. Currently, 10% of samples analyzed for lead in Fullerton is 5 parts per billion or higher. Though the city is in compliance with federal regulations, the EPA and CDC have both acknowledged 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.

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 380 parts per trillion. For the sake of perspective, these levels are nearly 19 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.

Still Have Questions About Fullerton Drinking Water?

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 Fullerton, but all of our our filters provide broad protection against a wide range of contaminants (including lead).

Problems We Found In Pasadena's Drinking Water

Problems We Found In Pasadena's 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.

Problems We Found With Sacramento's Drinking Water

Problems We Found With Sacramento's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Sacramento’s drinking and tap water, we aggregated water quality test data from the Sacramento Suburban Water District 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 we build for people in Sacramento are optimized with this research in mind.

Source Of Sacramento Drinking Water

The District has two service areas; North and South. The North Service Area (NSA) is supplied with water from local groundwater wells and, when available, with surface water treated by the San Juan Water District (SJWD). The South Service Area (SSA) is supplied with water from local groundwater wells and, when available, with treated surface water from the City of Sacramento. In 2016, the District supplemented the supply of both service areas with surface water.

Arsenic In Sacramento Drinking Water

Arsenic is a toxic 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 average arsenic concentrations are low in Sacramento, there were groundwater samples that reached 4 parts per billion.  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 both 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 Fresno's Drinking Water

Problems We Found in Fresno's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Fresno's water quality, we aggregated water quality test data from the City of Fresno Water Division 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 we build for people in Fresno are optimized with this research in mind.

Source Of Fresno Drinking Water

For Fresno residents, there are two sources of drinking water. One is derived from the Fresno Sole Source Aquifer, a large underground water system that supplies many communities in the San Joaquin Valley. The Water Division operates approximately 260 wells that draw from this aquifer. The second source of Fresno's drinking water is surface sourced water from the Sierra Nevada delivered via Fresno Irrigation District and Friant-Kern canals. This water is stored in both Millerton and Pine Flat lakes, located in the foothills east of Fresno. 

Extremely High Levels Of Chromium 6 In Fresno Drinking Water

Fresno's drinking water has one of the higher levels of Chromium 6 among major US cities.  Chromium 6 is a highly toxic metal that is not regulated by the EPA.  In recent years, Fresno tap and drinking water has averaged 2200 parts per trillion for Chromium 6.  For the sake of perspective, these levels are a staggering 110 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Fresno'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 Irvine's Drinking Water

Problems We Found In Irvine's Drinking Water

Emma Schultz, M.S. | Scientific Contributor   

For our assessment of Irvine's water quality, we aggregated water quality test data from the Irvine Ranch Water District, the water provider for Irvine, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze.  We cross reference these Irvine 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, managed by the Orange County Water District. Water is pumped from a natural underground reservoir that reaches from the Prado Dam across northwestern Orange County. Additional groundwater originates in the Cleveland National Forest from the Harding Canyon Dam watershed. Roughly 35% of Irvine’s water is supplied by the Metropolitan Water District of Southern California, imported from the Colorado River (and transported via the Colorado River Aqueduct), and from northern California (via the State Water Project).

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 ppb, with lead being found in 2 homes. While the Action Level is 15 ppb, both the EPA and CDC 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 Oakland's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Oakland's tap water quality, we aggregated water quality test data from East Bay Municipal Utility District, the water provider for the city 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 offer at Hydroviv are optimized with these numbers in mind. 

Source Of Oakland Drinking Water

Almost all of Oakland’s water comes from the 577-square mile watershed of the Mokelumne River on the western slope of the Sierra Nevada. This area is mostly national forest, EBMUD-owned lands and other undeveloped lands little affected by human activity. The Mokelumne watershed collects snowmelt from Alpine, Amador and Calaveras counties, which flows into Pardee Reservoir near the town of Valley Springs. Three large aqueducts carry water 90 miles from Pardee Reservoir to the East Bay.

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, 10% of samples analyzed for lead in Oakland is 5 parts per billion. Though Oakland's water quality is within compliance with federal regulations, the EPA and CDC have both acknowledged 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.

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 54 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.
