Problems We Found With Laredo's Drinking Water

BREAKING 9/29/2019:  Laredo has issued a city-wide boil order as the result of insufficient tap water chlorination.  The city has made the adjustment, and is monitoring levels across the system.  Please follow municipality's instructions for when the boil order is lifted. 

Emma Schultz, M.S. | Scientific Contributor   

For our assessment of city of Laredo's water quality, we aggregated water quality test data from the City Of Laredo Utilities 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 Laredo are optimized with these issues in mind.

Source Of Laredo Drinking Water

Laredo’s drinking water is surface water-based, and comes from the Rio Grande River. There are two water treatment plants that filter and treat water for Laredo customers. The Jefferson Water Treatment Plant has two separate river intakes, pump structures, and related pump units, although one of the pump structures has been permanently closed since 2013. The El Pico Water Treatment Plant is a new facility that commenced operations in 2015. In addition to these treatment plants and associated water storage facilities, Laredo has the option of using Webb County’s Lake Casa Blanca Reservoir in a water emergency.

Arsenic In Laredo Drinking Water

Arsenic is a hazardous heavy metal that can cause cancer and other health problems. Arsenic originates in source water naturally. While the city of Laredo'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. Laredo’s most recent tap water quality report listed a highest level detected of 4 parts per billion.  We strongly suggest that tap water with more than 1 part per billion be treated to remove arsenic, especially in homes with children.  

High Levels Of Disinfection Byproducts (DBPs) In Laredo 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. Laredo’s tap water has recently had high levels of DBPs, with a 2016 average of 103 parts per billion. The level of trihalomethanes (TTHM) detected in 2016 ranged as high as 147 ppb, which is nearly double the Maximum Contaminant Level (MCL) of 80 ppb. This was a violation, as TTHM levels exceeded the MCL in the 2nd, 3rd, and 4th quarters of 2016. While not a violation, the level of Haloacetic Acids detected also ranged above the MCL of 60 to 83.9 ppb.


Use Of Chlorine In Laredo Tap Water

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

Laredo made the news in September of 2016 when five schools tested positive for a lack of chlorine in their water supply, prompting the schools to provide students with bottled water until the system was flushed with enough chlorine to ensure safe levels of disinfection.


Still Have Questions About Laredo’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 Laredo 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 McAllen's Drinking Water

Kezia Snipe | Hydroviv Research Analyst


For Hydroviv’s assessment of tap water in McAllen, TX, we aggregated water quality test data from McAllen Public Utility, 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 McAllen Drinking Water

The sources of drinking water used by McAllen Public Utility are Surface Water and Ground Water. Water is received from the Falcon and Amistad Dams, located in Starr and Val Verde Counties, respectively. The water is transferred from the Rio Grande River by irrigation districts into reservoirs. 

Arsenic In McAllen 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. McAllen 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 3 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.  

Chromium 6 Levels In McAllen Drinking Water

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 7 parts per trillion for Chromium 6.  These levels are well within compliance with federal standards but do carry risks of having negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In McAllen 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 McAllen 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 McAllen, but all of our our filters provide broad protection against a wide range of contaminants (including lead).

If you’re interested in learning more about water filters that have been optimized for McAllen tap 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).

Problems We Found In Killeen's Drinking Water

Kezia Snipe | Hydroviv Research Analyst

For our assessment of Killeen tap water, we aggregated water quality test data from the City of Killeen, the water provider for Killeen, 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 Killeen are optimized with these issues in mind.

Source Of Killeen Drinking Water

The City of Killeen obtains its drinking water from Belton Lake, a surface water source located in Belton, Texas.

Disinfection Byproducts (DBPs) In Killeen 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. Killeen’s tap water had a 2016 average tested 119.7 parts per billion. This is well within the Maximum Contaminant Levels for Total Trihalomethanes and Haloacetic Acids.

Use Of Chloramine In Killeen Tap Water

While many cities use chlorine as the primary disinfectant, Killeen’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 Killeen was 3.4 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 Killeen use special filtration media that are purpose-built to remove chloramine as well.

Problems We Found In Garland, Texas Drinking Water

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 EPACDC, 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.

Problems We Found In Lubbock, Texas Drinking Water


Emma Schultz, M.S. | Scientific Contributor   
Updated August 5, 2019 to include current data

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.

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  4 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 1.5 parts per billion, with an upper range detection of 8.6 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.

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.

Problems We Found In San Antonio Drinking Water

Kezia Snipe | Hydroviv Research Analyst

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

We've updated our water quality report for San Antonio to include 2019 data. Our Water Nerds analyzed the most recent available data from the San Antonio Water System, U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. We compare these data with toxicity studies in scientific and medical literature, and look at upcoming regulatory changes. The water filters that Hydroviv builds for San Antonio customers are optimized with these numbers in mind.

Source Of San Antonio Drinking Water 

The San Antonio Water System draws groundwater from the Edwards, Carrizo and Trinity aquifers. In certain areas and, San Antonio will draw surface water from Canyon Lake.

Lead In San Antonio 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 San Antonio are 3.25 parts per billion. Though San Antonio's water quality is in compliance with federal regulations, EPACDC and The American Academy of Pediatrics all agree that there is no safe level of lead for children.

Chromium 6 In San Antonio Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, San Antonio tap water has averaged 136 parts per trillion for Chromium 6. For the sake of perspective, these levels are nearly 7 times higher than the concentration determined to have negligible impact on cancer risk


Disinfection Byproducts (DBPs) In San Antonio Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter in water. Although these chemicals are not well regulated, EPA has acknowledged 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 San Antonio 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 San Antonio's water quality, but all of our  filters provide broad protection against a wide range of contaminants (including lead).
