Problems We Found With Phoenix Water Quality

Kezia Snipe | Hydroviv Research Analyst   

For Hydroviv’s assessment of Phoenix's water quality, we aggregated water quality test data from City of Phoenix Water Services Department, the water provider for Arizona’s capital 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 the scientific and medical literature, and look at upcoming regulatory changes.  The water filters that we offer at Hydroviv are optimized with this research in mind.

Source Of Phoenix Drinking Water

The sources of Phoenix’s city and tap water include rivers, lakes, streams, springs and wells. In 2016, about 98 percent of Phoenix’s water came from surface water that mostly started as snow pack. Phoenix’s primary sources of untreated surface water are the Salt, Verde and Colorado rivers. Some water from the Agua Fria River is mixed with water from the Colorado River when stored in Lake Pleasant. The water is then delivered to one of the city’s five water treatment plants. Colorado River water is delivered to the city via the Central Arizona Project aqueduct. Water from the Salt and Verde rivers is delivered via the Salt River Project canal network. The remaining two percent of Phoenix' drinking water was supplied by about 20 groundwater wells currently operated by the city.

Chromium 6 In Phoenix Drinking Water Is Highest In The US

Chromium 6 (also known as hexavalent chromium) is a highly toxic metal that is not regulated by the EPA.  Unfortunately, Phoenix's city and tap water  has the highest levels of this toxic metal among all major US cities.  In recent years, tap water in Phoenix has averaged 8 parts per billion for Chromium 6, with a maximum of 54 parts per billion.  For the sake of perspective, these levels correspond to 400x and 2700x higher than the concentration determined by toxicologists to have negligible impact on cancer risk.   We strongly recommend that all Phoneix residents filter their water for chromium 6.

Arsenic In Phoenix 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.  Phoenix is in compliance with EPA water quality standards but it’s important to mention that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. Phoenix's most recent tap water quality report shows an average arsenic concentration up to 8 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.  

Lead Levels In Phoenix 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 recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Currently, 10% of samples analyzed for lead in Phoenix are over 5 parts per billion.  While currently 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.  

Disinfection Byproducts (DBPs)

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.

Chlorine

Like many other municipalities in the United States, Phoenix injects its city and tap water with chlorine, which is typically used to protect against waterborne illness.  Chlorine is not typically considered to be harmful on its own but many find that removing chlorine from drinking water greatly enhances its taste and odor.  

Still Have Questions?

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” for the filters that we sell in Phoenix, but all of our filters provide broad protection against other contaminants commonly found in drinking water (e.g. VOCs, solvents, pesticides, mercury).  If you’re interested in learning more about our city-specific water filters, 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, so check us out!

Problems We Found In Oklahoma City's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s Oklahoma City water quality report, we aggregated water quality test data from Oklahoma City Utilities, 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 Oklahoma City are optimized with these figures in mind.

Source Of Oklahoma City Drinking Water

Oklahoma City’s water footprint spans 250 miles and includes seven surface water reservoirs from five counties in Oklahoma. They include Canton Lake in northwest Oklahoma, McGee Creek, Lake Atoka, and Sardis Lake in southeastern Oklahoma, as well as Lake Overholser, Lake Hefner and Lake Stanley Draper in Oklahoma City.

Arsenic In Oklahoma City 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. Long Beach is in compliance with the EPA’s water quality standards but it is very important to point out that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. The most recent Oklahoma City water quality report revealed an average arsenic concentration up to 2 parts per billion for  the cityHydroviv recommends that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children. 

Chromium 6 Levels In Oklahoma City Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA.  In recent years, Oklahoma City’s tap water has averaged 110 parts per trillion for Chromium 6, with levels reaching 390 parts per trillion.  While they are in compliance with nonexistent federal and very loose state regulations, these levels are 5.5-19 times higher than the concentration determined to have negligible impact on cancer risk

Lead Levels In Oklahoma City Tap Water

Lead is a contaminant that enters OKC's tap water when it leaches from lead-containing pipes, valves, joints, and fixtures, and homes built before 1986 are particularly susceptible.  2015 was the most recent year when Oklahoma City collected samples for lead analysis, and they found that the 90th percentile was 5 parts per billion or below.  For sake of comparison, the American Academy Of Pediatrics is lobbying for policy that fixes taps for children that produce water with more than 1 part per billion lead.

Disinfection Byproducts (DBPs) In Oklahoma City 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.  Oklahoma City's disinfection byproduct levels are on the upper end of compliance.

Use Of Chloramine In Pittsburgh Tap Water

While most cities use chlorine as the primary disinfectant, Oklahoma City water is disinfected with chloramine (which is formed by mixing chlorine and ammonia).  Chloramine is the primary culprit for what many customers report as the “bad taste”of tap water, and unlike chlorine will not dissipate if left in the fridge overnight.  Most one-size-fits-all water filters use filtration media that successfully removing chloramine, but the filters that Hydroviv builds for Oklahoma  City use special filtration media that are designed to remove chloramine as well.

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

Problems We Found In Jacksonville's Drinking Water

Kezia Snipe | Research Analyst

For our assessment of Jacksonville's tap and drinking water quality, we aggregated water quality test data from the Jacksonville Electric Authority, the water provider for the Florida 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 for our Jacksonville customers with these numbers in mind.

Source Of Jacksonville Drinking Water

Jacksonville’s drinking water comes from the Floridan aquifer, one of the major sources of groundwater in the United States. Floridan wells are protected from surface chemical contamination by the Hawthorne formation, which is a thick layer of clay that prevents pollutants from seeping below it. Water comes from over 115 Floridan wells throughout Duval, St. Johns and Nassau Counties and is pumped from the aquifer into large reservoirs at one of 37 water treatment plants.

Arsenic Detected In Jacksonville 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 Jacksonville is in compliance with EPA water quality standards, it’s important to point out that EPA’s drinking water standards balance the toxicity of the contaminant against the costs of it at the municipal scale. The most recent tap water quality report for Jacksonville reported an average arsenic concentration of 2.75 parts per billion. Hydroviv strongly recommends that anyone that lives in an area with more than 1 part per billion take steps to remove arsenic from their water, especially families with children.  

Lead Levels Found In Jacksonville 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 recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Currently, 10% of samples analyzed for lead in Jacksonville are 2.26 parts per billion. Though Jacksonville's drinking water quality is in compliance with loose 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.  

Disinfection Byproducts (DBPs) In Jacksonville Drinking Water

Disinfection Byproducts (DBPs) are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter.  Although these chemicals are only loosely regulated at this time, the EPA  website discloses that that high levels of DBPs are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Chlorine In Jacksonville Drinking Water

Like most other municipalities in the U.S., Jacksonville injects its water with chlorine to protect against waterborne illness. While not typically considered to be harmful on its own, many people find that removing chlorine from drinking water greatly enhances its taste and odor.

Problems We Found In Milwaukee's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Milwaukee's tap and drinking water quality, we aggregated water quality test data from Milwaukee Water Works, 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 look at upcoming regulatory changes.  The water filters that we build for our neighbors in Milwaukee (Hydroviv is a DC-based company) are optimized with this research in mind.

Source Of Milwaukee's Drinking Water

Milwaukee draws it's raw and drinking water from Lake Michigan.

High Levels Of Lead In Milwaukee Drinking Water

Lead enters Milwaukee's drinking and tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Currently, 10% of samples analyzed for lead in Milwaukee are over 8.2 parts per billion. Though Milwaukee's drinking water quality is currently 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.  Homes built before 1986 are most susceptible to lead contamination.  The American Academy of Pediatrics recommends that any taps used to serve children have lead levels no higher than 1 part per billion.

High Levels Of Chromium 6 In Milwaukee Drinking Water

Chromium 6 is a hazardous metal not fully regulated by the EPA. Milwaukee’s tap and drinking water recently averaged 220 parts per trillion for chromium 6. These levels are nearly 11 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Milwaukee 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 Omaha's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For Hydroviv’s assessment of Omaha’s tap and drinking water, we aggregated water quality test data from Metropolitan Utilities District, the water provider for Omaha, 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 Omaha are optimized with this research in mind.

Source Of Omaha Drinking Water

Sources of Omaha's tap and drinking water include the Missouri and Platte Rivers and the Dakota sandstone aquifer. These sources are categorized as surface water (Missouri River), groundwater under-the-direct-influence of surface water (Platte River) and groundwater. Water is pumped from intakes and wells maintained by the District.

Arsenic In Omaha 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. Omaha's most recent tap water quality report for Omaha reported an average arsenic concentration of 5.07 parts per billion.  These levels are high enough that cities like Omaha place the following boilerplate disclosure in their consumer confidence report.

"While your drinking water meets EPA’s standard for arsenic, it does contain low levels of arsenic. EPA’s standard balances the current understanding of arsenic’s possible health effects against the cost of removing arsenic from drinking water. EPA continues to research the health effects of low levels of arsenic, which is a mineral known at high concentrations to cause cancer in humans 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.  

Lead In Omaha 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 recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Currently, 10% of samples analyzed for lead in Omaha are over 6.4 parts per billion.  While Omaha's water quality is currently 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.

Chromium 6 In Omaha Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA.  In recent years, Omaha's tap and drinking water has averaged 610 parts per trillion for Chromium 6, with concentrations reaching up to nearly 2 parts per billion.  For the sake of perspective, these levels are 31-100 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Omaha 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. 

Chloramine Is Used In Omaha Tap Water Instead of Chlorine

While most cities use chlorine as their primary disinfectant, Omaha water is disinfected with chloramine (a product of chlorine and ammonia). Chloramine is primarily responsible for what customers often report as the “bad taste”of tap water, and unfortunately does not dissipate if a container of water is left in the fridge overnight. Most one-size-fits-all water filters use filtration media that doesn’t adequately remove chloramine, but the custom water filters that Hydroviv builds for Omaha use special filtration media that are purpose-built to remove chloramine as well.

How Do I Filter Chromium 6 From Drinking Water?

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 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.  Recent analysis for lead in Riverside found 90th percentile concentraions of 5 parts per billion.  While Riverside's water quality 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 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).

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.
