Water Quality Reports

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

For our Garland water report, we aggregated water quality test data from Garland Water Utilities, 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 Garland are optimized with these issues in mind.

Source Of Garland Drinking Water

Garland’s drinking water is surface water-sourced, and is purchased from the North Texas Municipal Water District (NTMWD). Water is pumped from Lavon Lake, Jim Chapman Lake, Lake Tawakoni, Lake Texoma, and the East Fork Raw Water Supply Project. Water is treated at one of the NTMWD’s six water treatment plants before being distributed to the City of Garland. Water may be stored in one of eight ground storage tanks or three elevated storage tanks.

Lead In Garland Drinking Water

Lead enters into tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as recently seen in Flint, Michigan), lead leaches into drinking water and can reach hazardous levels. A recent water quality analysis for Garland revealed a 90th percentile concentration of 3.88 parts per billion. While the Action Level is 15 parts per billion, both the EPA, CDC, and the American Academy of Pediatrics all recognize that there is no such thing as a safe level of lead for children. In addition, federal regulations cannot take into account levels measured at an individual tap.

Chromium 6 In Garland Drinking Water

Chromium 6 is a highly toxic metal that, although monitored, is not regulated by the EPA. Garland’s tap water recently averaged 91.2 parts per trillion for chromium 6. These average levels are over 4 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Garland Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. While these chemicals are not well regulated, the EPA has stated they have an association with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. EPA regulates two categories of DBPs: Total Trihalomethanes (TTHMS) and Haloacetic Acids 5 (HAA5). The average concentration of TTHMs is 36 parts per billion, and 25 parts per billion for HAA5. For a bit of perspective, the outdated Maximum Contaminant Level for TTHMs is 80 parts per billion and 60 parts per billion for HAA5.

Use Of Chloramine In Garland Tap Water

While most cities use chlorine as their primary disinfectant, the City of Garland’s water is disinfected with chloramine, produced by mixing chlorine and ammonia. Chloramine is primarily responsible for what customers report as the “bad taste” of tap water, and unlike chlorine this bad taste will not fade 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 filters that Hydroviv builds for Garland use special filtration media that is purpose-built to remove chloramine as well.

In 2016, the running annual average for chloramines was 2.93 parts per million and the upper detected range was 4.2 parts per million, which is over the Maximum Residual Disinfectant Level (MRDL) of 4.0 parts per million. It is important to note that while this is above the MRDL, it is not a violation.

Still Have Questions About Garland’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 Garland 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 reflect current water quality data

For Hydroviv’s City of Mesa, AZ Water Report we aggregated water quality test data from Mesa Water Resources, U.S. Environmental Protection Agency (EPA) and 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 Mesa Drinking Water

Mesa relies on two sources for its drinking water: surface water and groundwater wells. Salt and Verde River water from the Salt River Project (SRP) supplies water delivered in the City Zone. Colorado River water delivered through the Central Arizona Project (CAP) provides water delivered in the Eastern Zones. 16 deep aquifer wells supply drinking water throughout the City Zone. 14 deep aquifer wells supply drinking water throughout a wide area in Mesa’s Eastern Zones.

Arsenic In Mesa 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. Mesa's water quality is in compliance with the EPA’s water quality standards but it’s important to point out that EPA’s standard balances the toxicity against the costs of removing arsenic from drinking water. The city’s most recent tap water quality report reported an average arsenic concentration up to 7.8 parts per billion. Hydroviv recommends that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children.

Lead In Mesa 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 Mesa, AZ's water are 3.7 parts per billion. Though Mesa's water quality is 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.

Extremely High Chromium 6 Levels In Mesa Drinking Water

Mesa's water quality has one of the highest levels of Chromium 6 in its' tap water in the entire country. 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 5600 parts per trillion for Chromium 6. For a bit of perspective, these levels are 280 times HIGHER than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Mesa 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.

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 Mesa, AZ's water, but all of our our filters provide broad protection against a wide range of contaminants (including lead).

For our Gilbert water quality report, we aggregated water quality test data from the City of Gilbert’s Water Quality 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 the scientific and medical literature, and look at upcoming regulatory changes. The water filters that we sell in Gilbert are optimized with these issues in mind.

Source Of Gilbert Drinking Water

Gilbert’s drinking water is both groundwater- and surface water-sourced. Surface water originates from the Salt River Project, with dams and reservoirs located on the Salt River and Verde River watersheds; and from the Central Arizona Project, drawing water from the Colorado River via Lake Havasu in a canal. All surface water is directed to one of Gilbert’s two water treatment plants, either the North Water Treatment Plant or the Santan Vista Water Treatment Plant. The Santan Vista plant is working to double its water production capabilities, which should be finished by early 2018. Groundwater is pumped as needed from 17 wells located throughout Gilbert, with ion exchange or adsorptive media used at some wells to reduce inorganic contaminant concentrations. In 2016, SRP provided 49% of the water used, while groundwater supplied 28% and CAP 23%.

Arsenic In Gilbert Drinking Water

Arsenic is a dangerous heavy metal known to cause cancer, among other health problems. Arsenic originates in source water. While the city of Gilbert's water report is in compliance with EPA water quality standards, consumers should take note that the EPA's standard balances toxicity against the costs of removing arsenic from drinking water; the standard is therefore quite high. The city of Gilbert's most recent water report listed average arsenic concentrations ranging from 3.2-9.1 parts per billion, with an average concentration of 6.43 ppb. Although this is a not an EPA violation, we strongly advocate that tap water with more than 1 part per billion be treated to remove arsenic, especially if there are children in the home.

Lead In Gilbert Drinking Water

Lead enters consumer 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 drinking water and can reach toxic levels. Recent analysis for lead in Gilbert found a 90th percentile concentration of 1.33 ppb, with an upper range limit of 2.9 ppb. 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. In addition, federal regulations cannot possibly take into account levels measured at an individual tap.

Very High Levels Of Chromium 6 In Gilbert Drinking Water

Chromium 6 is a highly toxic metal that, while monitored, is not regulated by the EPA. Gilbert’s tap water recently averaged 5900 parts per trillion for chromium 6. These average levels are a staggering 295 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Gilbert 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 well regulated, the EPA has stated that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. DBPs in Gilbert’s tap water had a 2016 local running annual average of 48.0089 parts per billion. It should be noted that levels of Total Trihalomethanes ranged as high as 110 ppb, while the EPA’s Maximum Residual Disinfectant Level is only 80 ppb. While over the MRDL, this is not an EPA violation since local running annual averages are used for comparison.

Use Of Chlorine In Gilbert Tap Water

Like most cities in the United States, Gilbert adds chlorine to its water supply to keep consumers safe from waterborne pathogens. While not considered harmful in low concentrations, many people find that removing the chlorine from their water supply results in a taste and odor improvement. When you choose to filter your tap water, we believe you will notice an immediate taste enhancement.

For Hydroviv’s assessment of Raleigh drinking and tap water, we aggregated water quality test data from the City Of Raleigh Public Utilities Department, 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 Raleigh water 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 Raleigh Drinking Water

Raleigh sources its drinking water from Lake Benson and Falls Lake.

PFAS In Raleigh Drinking Water

Per and Polyfluoroalkyl Substances or PFAS are a category of chemicals found in various non-stick/stain resistant products, as well as fire fighting foam. PFAS are considered to be "emerging contaminants" because they are not currently regulated by EPA, but are known to be toxic, carcinogenic, and persistent in the environment. High levels of PFAS have been detected throughout the entire state of North Carolina, specifically in Raleigh tap water. Most municipalities don't test for or remove PFAS from tap water, and most water filters are not designed to remove PFAS. A recent study by Duke University and NC State University revealed elevated levels in of a variety of PFAS compounds in Raleigh tap water.

Lead In Raleigh Drinking Water

Lead enters Raleigh'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 Raleigh are less than 3 parts per billion. Though Raleigh's water quality 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 Raleigh Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Raleigh tap and drinking water averaged 56 parts per trillion. For the sake of perspective, these levels are 3 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Raleigh 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 Raleigh Drinking Water?

Per and Polyfluoroalkyl Substances (PFAS) are being identified in a growing number of municipalities across the United States. San Francisco has not yet tested for PFAS, but several variations have been detected throughout the state of California. Not all water filters are designed to remove PFAS from 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 Raleigh, but all of our our filters provide broad protection against a wide range of contaminants (including lead).

**Updated June 25, 2021 to include current data

Our team has updated our assessment of Hampton drinking water to include the most current available data. To do this, we've aggregated water quality test data from Newport News Waterworks Department, the U.S. Environmental Protection Agency (EPA), as well as 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 to remove contaminants in Hampton, Virginia drinking water.

Source Of Hampton Drinking Water

Hampton supplies its drinking water from both surface and groundwater sources. The surface supply comes from the Chickahominy River. Supplementary groundwater is supplied from wells in the Lee Hall area. Waterworks owns and operates five reservoirs that store and supply water to the treatment plants. The two source waters are treated separately, then blended together before being distributed to Hampton residents. 

Per and Polyfluoroalkyl Substances (PFAS) In Hampton Drinking Water

PFAS are a class of chemicals found in various non-stick and stain resistant products, as well as fire fighting foam. PFAS are considered to be "emerging contaminants" because they are not currently regulated by EPA, but are known to be both toxic and persistent in the environment. PFAS have historically been an ingredient in fire fighting foam, which is why they're often found on or near military bases. The Langley Air force Base Hampton detected PFAS levels between 26,000-220,000 parts per trillion, which are upwards of 11,000 times higher than advisory levels. Hydroviv undersink filters remove PFAS. If you'd like to check out third-party data on our removal rates, send us an email at hello@hydroviv.com.

Lead In Hampton 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, the 90th percentile for lead in Hampton drinking water is around 1 part per billion. Though the city of Hampton's water quality is well within in compliance with federal regulations, the EPA, CDC and The American Academy of Pediatrics all acknowledged that there is no safe level of lead for children. Additionally, if your home was built before 1986, you most likely have internal lead pipes and plumbing.

Chromium 6 In Hampton Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Hampton tap water averaged 90 parts per trillion. For the sake of perspective, these levels are nearly 5 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Hampton 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.
