Haslet Water Quality & Filtration Guide

Introduction To Water Quality in Haslet

Haslet, Texas is a growing suburban city within the Dallas-Fort Worth metroplex, primarily located in Tarrant County with a portion extending into Denton County. The city's municipal water system serves approximately 1,720 residents, with water sourced primarily from purchased surface water rather than locally extracted groundwater. This purchased water undergoes treatment before distribution through the municipal system.

While Haslet's municipal water supply currently meets all federal health-based drinking water standards according to the Environmental Protection Agency (EPA) and Texas Commission on Environmental Quality (TCEQ), our analysis has identified several contaminants present at levels exceeding health guidelines established by independent research organizations. This report examines:

• The current state of Haslet's municipal water quality
• Potential concerns for residents using private well water
• Health implications of identified contaminants
• Effective filtration approaches to address water quality issues

All Haslet residents should understand that compliance with federal standards doesn't necessarily indicate optimal water quality. Several substances exist at levels below legal limits but above health guidelines established by independent research organizations based on the latest scientific research.

Contaminants and Pollutants in your Local Water

Our analysis of Haslet's municipal water, based on tests conducted between 2014 and 2019, revealed the presence of several concerning contaminants. While all detected substances remain below federally established legal limits, many exceed the more stringent health guidelines established by the Environmental Working Group (EWG).

The primary contaminants of concern in Haslet's water include:

• Carcinogenic Compounds
  • Arsenic (0.495 ppb) - 124 times higher than EWG health guideline
  • Radium (Combined -226 & -228) (0.31 pCi/L) - 6.3 times higher than EWG health guideline
• Disinfection Byproducts
  • Haloacetic Acids (HAA5) (6.63 ppb) - 66 times higher than EWG health guideline
  • Bromate (1.06 ppb) - 11 times higher than EWG health guideline
  • Bromochloroacetic Acid (3.23 ppb) - 162 times higher than EWG health guideline
• Agricultural and Fertilizer-Related Contaminants
  • Nitrate (0.459 ppm) - 3.3 times higher than EWG health guideline
  • Nitrate and Nitrite (Combined) (0.524 ppm) - 3.7 times higher than EWG health guideline

It's important to note that these contaminants, while exceeding health guidelines, remain below federal legal limits. However, mounting scientific evidence suggests that long-term exposure to even low levels of these substances may pose health risks, particularly for vulnerable populations.

Explanation of Contaminants and their Problems

Arsenic

Arsenic was detected in Haslet's water at 0.495 parts per billion (ppb), which is 124 times higher than the EWG health guideline of 0.004 ppb, though still below the federal legal limit of 10 ppb. This naturally occurring element enters water supplies through both geological processes and human activities including agriculture and industry.

Long-term exposure to arsenic, even at low levels, presents serious health concerns:

• Cancer Risk: Arsenic is a potent carcinogen known to cause thousands of cancer cases annually in the United States, particularly affecting the bladder, lungs, and skin.
• Cardiovascular Effects: Research has linked chronic arsenic exposure to increased risk of heart disease and high blood pressure.
• Neurological Impacts: Exposure during critical developmental periods may affect cognitive function, particularly in children.
• Endocrine Disruption: Arsenic can interfere with normal hormone function at low exposure levels.

While Haslet's arsenic levels remain below legal limits, the significant exceedance of health guidelines warrants attention, especially for households with pregnant women, infants, or immunocompromised individuals.

Radium (Combined -226 & -228)

Radium was measured at 0.31 picocuries per liter (pCi/L) in Haslet's water, exceeding the EWG health guideline of 0.05 pCi/L by 6.3 times while remaining below the legal limit of 5 pCi/L. This radioactive element typically enters drinking water through natural geological processes but can be elevated in areas with certain types of mining or extraction activities.

Health concerns associated with radium exposure include:

• Bone Cancer: As a calcium-mimicking substance, radium accumulates in bone tissue, increasing cancer risk with long-term exposure.
• Other Cancers: Studies have associated radium exposure with increased risks of lymphoma and leukemia.
• Chronic Radiation Exposure: As a radioactive element, radium emits radiation as it decays, potentially damaging cellular DNA over time.

Residents should be particularly concerned about radium if they have lived in Haslet for many years, as the health effects typically result from long-term cumulative exposure.

Haloacetic Acids (HAA5)

Haloacetic acids were found in Haslet's water at 6.63 ppb, which is 66 times the EWG health guideline of 0.1 ppb, though still below the legal limit of 60 ppb. These disinfection byproducts form when chlorine or other disinfectants react with naturally occurring organic matter in water.

Potential health impacts from haloacetic acid exposure include:

• Cancer Risk: Long-term exposure has been linked to increased bladder cancer risk in multiple epidemiological studies.
• Reproductive Effects: Some research suggests possible links to adverse pregnancy outcomes, including low birth weight and birth defects.
• Liver and Kidney Function: Animal studies indicate potential effects on liver and kidney health with chronic exposure.

While these compounds result from necessary disinfection processes that prevent waterborne diseases, their presence at elevated levels represents an unintended consequence that should be addressed through appropriate filtration.

Bromate

Bromate was detected at 1.06 ppb in Haslet's water, exceeding the EWG health guideline of 0.1 ppb by 11 times while remaining below the legal limit of 10 ppb. This carcinogenic disinfection byproduct forms when source waters containing bromide are treated with ozonation or sodium hypochlorite.

Health concerns associated with bromate include:

• DNA Damage: Laboratory studies indicate that bromate damages DNA and causes cancer in multiple organs.
• Kidney Toxicity: Animal studies have shown bromate can cause kidney damage at high doses.
• Nervous System Effects: Some research suggests potential neurological impacts from long-term exposure.

Like other disinfection byproducts, bromate represents a trade-off between necessary water treatment and the creation of potentially harmful compounds, emphasizing the importance of post-treatment filtration.

Bromochloroacetic Acid

This disinfection byproduct was measured at 3.23 ppb in Haslet's water, which is 162 times higher than the EWG health guideline of 0.02 ppb. There is currently no federal legal limit for this compound, highlighting the gap between regulated contaminants and substances of emerging concern.

Potential health effects from bromochloroacetic acid exposure include:

• Cancer Risk: Studies suggest potential carcinogenic properties similar to other haloacetic acids.
• Reproductive Health: Animal studies indicate possible effects on reproductive system development.
• Embryonic Development: Some research suggests potential impacts on embryonic development with exposure during pregnancy.

The extremely high exceedance of health guidelines for this unregulated compound makes it a particular concern for Haslet residents, especially those in vulnerable populations.

Nitrate and Nitrite

Nitrate levels were reported at 0.459 parts per million (ppm) in Haslet's water, exceeding the EWG health guideline of 0.14 ppm by 3.3 times, while remaining well below the legal limit of 10 ppm. Combined nitrate and nitrite levels were found at 0.524 ppm, which is 3.7 times the EWG health guideline. These fertilizer chemicals enter water supplies through agricultural runoff, urban runoff, and wastewater discharge.

Health concerns associated with nitrate and nitrite exposure include:

• Methemoglobinemia (Blue Baby Syndrome): High nitrate levels can interfere with oxygen transport in infants, potentially causing this serious and sometimes fatal condition.
• Cancer Risk: Long-term studies have associated nitrate exposure with increased risks of colorectal cancer and thyroid cancer.
• Thyroid Function: Some research suggests nitrate exposure may interfere with normal thyroid function.

While Haslet's levels remain well below the regulatory threshold for acute effects like blue baby syndrome, the chronic exposure concerns associated with cancer risk and endocrine disruption warrant attention.

Deep Dive on Well Water Quality in the Area

While specific data on private wells in Haslet is limited, residents using well water should be aware of potential contamination issues unique to groundwater sources. Unlike municipal water, private wells don't receive the same treatment or regular testing, making independent assessment crucial.

The North Texas region, including Haslet, faces several groundwater quality challenges:

• Naturally Occurring Contaminants: The geological formations underlying Haslet may contain elevated levels of arsenic, radium, and other naturally occurring elements that can leach into groundwater.
• Agricultural Impacts: As a historically agricultural area, groundwater in and around Haslet may contain elevated nitrate and pesticide levels from decades of farming activities.
• Oil and Gas Activities: The broader region has seen extensive oil and gas development, which can potentially impact groundwater quality through spills, leaks, or migration from improperly sealed wells.

Well owners in Haslet should be alert to potential signs of water quality issues, including:

• Strange odors resembling chlorine, sulfur (rotten eggs), or metallic smells
• Cloudy or discolored water
• Staining on fixtures or laundry (orange/brown for iron, blue/green for copper)
• Scaling or mineral buildup on plumbing fixtures and appliances
• Gastrointestinal symptoms among household members

Regular well flow testing and comprehensive water quality assessment are essential for Haslet residents relying on private wells. At minimum, annual testing should include bacteria, nitrates, pH, total dissolved solids, and every 3-5 years should include a more comprehensive panel including arsenic, radium, and other potential contaminants of concern.

Filtration Recommendations for Haslet

Based on Haslet's specific contaminant profile, we recommend a multi-barrier approach to water filtration that addresses the full spectrum of identified substances. No single filtration technology removes all contaminants effectively, making a strategic combination necessary for comprehensive protection.
