**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).

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.

Our Water Nerds have updated our analysis of Durham, North Carolina drinking water to include the most updated data. Our team has aggregated water quality test data from the City of Durham Department of Water Management, 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 Durham are optimized with these issues in mind.

Source Of Durham Drinking Water

Durham gets its drinking water from surface water sources. The two primary sources are Lake Michie and Little River Reservoir. Supplementary water is supplied by Jordan Lake and Teer Quarry. The two treatment plants in Durham are the Williams Water Treatment Plant and the Brown Water Treatment Plant.

PFAS In Durham 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 Durham. 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 Durham tap water. 

Lead In Durham Drinking Water

Lead enters Durham drinking water through older lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as in Flint, Michigan), lead leaches into drinking water and reaches toxic levels. Recent analysis for lead in Durham tap water found 90th percentile concentrations of .003 parts per billion. Although the Action Level for lead is 15 ppb, both the EPA and CDC recognize that there is no such thing safe levels of lead. Of course, federal regulations cannot take into account levels measured at an individual tap.

Disinfection Byproducts (DBPs) In Durham Drinking Water

DBPs are a category of emerging contaminants formed when chlorine-based disinfectants combine with naturally-occurring organic matter. While these chemicals are not well 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. Both regulated types of DBPs (total trihalomethanes and haloacetic acids 5) are elevated in Durham drinking water. 

Use Of Chloramine In Durham Tap Water

While many cities use chlorine as their primary disinfectant, Durham’s water is disinfected with chloramine, made by combining chlorine and ammonia. Chloramine is the frequent culprit 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 running annual average for Durham was 2 parts per million. Most one-size-fits-all water filters use filtration media that don’t adequately remove chloramine, but the filters that Hydroviv builds for Durham use special filtration media that are purpose-built to remove chloramine as well.

For our Lubbock water quality assessment, we aggregated water quality test data from the Lubbock Water Department, 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 Lubbock are optimized with these issues in mind.

Source Of Lubbock Drinking Water

Lubbock’s drinking water is a mixture of surface and groundwater. 58% of Lubbock drinking water comes from the Robert County Well Field, 19% from Lake Alan Henry, 13% from Bailey County Well Field, and 10% from Lake Meredith. Water from the Roberts County and Bailey County well fields is supplied from the Ogallala Aquifer. These four sources of water travel 65-160 miles to reach Lubbock.

PFAS In Lubbock 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. PFAS have been detected in at the former Reese Air Force Base. Most municipalities, including Lubbock, don't test for or remove PFAS from tap water, and most water filters are not designed to remove PFAS. If you'd like to find a water filter that removes PFAS from tap water, check out this Duke/NC State PFAS study.

Arsenic In Lubbock Drinking Water

Arsenic is a dangerous heavy metal known to cause cancer, among other health problems. Unlike lead which accumulates in distribution pipes, Arsenic originates in source water itself. While Lubbock's is in compliance with EPA standards, consumers should take note that the EPA standards for arsenic balances toxicity against the costs of removing it from drinking water. That being said, the standard is much higher than health experts would advise. According to the most recent report, the highest detected arsenic concentration in Lubbock drinking water is 2 parts per billion. We strongly encourage 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 Lubbock 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 the drinking water and can reach toxic levels. Recent analysis for lead in Lubbock found a 90th percentile concentration of less than 14 parts per billion, with an upper range detection of 41 parts per billion. While the Action Level is 15 parts per billion, both the EPA and CDC recognize that there is no such thing as a safe level of lead for children. In addition, federal regulations cannot possibly take into account levels measured at an individual tap. Hydroviv Undersink filters are NSF/ANSI 53 certified to remove lead from drinking water.

Chromium 6 In Lubbock Drinking Water

Chromium 6 is a highly toxic metal that, while monitored, is not regulated by the EPA. Lubbock’s tap water quality recently averaged 932 parts per trillion for chromium 6. Average levels are 46 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Lubbock 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 concluded that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. DBPs in Lubbock’s tap water had a 2016 average of 49.4 parts per billion.

Use Of Chloramine In Lubbock Tap Water

While most cities use chlorine as the primary disinfectant, Lubbock's Drinking Water is disinfected with chloramine, which is produced by mixing chlorine and ammonia. Chloramine is primarily responsible for what many 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 Lubbock uses special filtration media that is purpose-built to remove chloramine as well.

In 2016, while the running annual average for chloramines was 2.9 ppm, the upper detected range was 4.4 ppm, which is over the Maximum Residual Disinfectant Level of 4.0 ppm. It is important to note that this is not a violation.

**Updated May 30, 2021 to include current data

Our Water Nerds have updated our assessment of Buffalo's drinking water to include the most recent available data. We used information from Buffalo Water, U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. We're then able to cross reference these data with toxicity studies in scientific and medical literature. The custom water filters that we sell in Buffalo are optimized to remove present contaminants.

Source Of Buffalo Drinking Water

Buffalo’s gets its tap water from Lake Erie. Despite its size, Lake Erie is a very shallow lake, and has a water detention time of only 2.6 years. This quick turnaround time for water replenishment helps to explain the success of cleanup efforts following the heavy pollution of Lake Erie in the 1960s and 1970s. Buffalo’s city water intake is located upstream of the Niagara River in the Emerald Channel, and flows through a mile-long tunnel before reaching a pumping station. Water then proceeds to underground basins for treating and filtering, before being stored in a 28 million gallon clearwell.

Lead In Buffalo 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 toxic levels. According to the most recent report, the 90th percentile detected was 2.7 parts per billion. While the regulatory limit 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. Of course, federal regulations cannot take into account levels measured at an individual tap.

Chromium 6 In Buffalo Drinking Water

Chromium 6 is a highly toxic metal not regulated by the EPA. The city of Buffalo’s tap water recently averaged 100 parts per trillion for chromium 6. These levels are 4 times higher than the concentration determined to have a negligible impact on cancer risk.

Use Of Chlorine In Buffalo Tap Water

Like many cities in the United States, Buffalo adds chlorine to its drinking and tap water supply to keep consumers safe from waterborne illness. While not considered overtly harmful, many people find that when they remove the chlorine from their tap water, they notice an improvement in taste and odor. When you choose to filter your tap water, we believe you will notice an immediate taste enhancement.
