Contaminant Analysis
View Data SourcesArsenic
CarcinogenWhat is it?
Arsenic is a naturally occurring element that enters groundwater from rock formations. Industrial pollution and agricultural runoff can also contaminate water supplies with this potent toxin.
Health Risks
Long-term arsenic exposure is linked to skin, bladder, lung, and kidney cancers. It also causes cardiovascular disease, diabetes, and neurological damage. The EPA classifies arsenic as a Group A carcinogen.
How to Remove It
Standard carbon filters cannot remove arsenic. Reverse Osmosis, distillation, or specialized arsenic-removal media (iron-based adsorption) are required for safe removal.
Get a Certified SolutionColiform
BacteriaWhat is it?
Coliform bacteria are organisms found in the digestive systems of warm-blooded animals. Their presence in water indicates potential contamination from human or animal waste.
Health Risks
While total coliform itself may not cause illness, its presence signals that dangerous pathogens like E. coli, Cryptosporidium, or viruses may also be in your water supply.
How to Remove It
Bacteria require UV disinfection or certified microbial purification systems. Boiling water kills bacteria but is not a sustainable long-term solution.
Get a Certified SolutionHaloacetic Acids
ByproductWhat is it?
Haloacetic acids (HAA5) are disinfection byproducts formed when chlorine or other disinfectants react with natural organic matter in water.
Health Risks
Long-term exposure to haloacetic acids may increase cancer risk and cause reproductive and developmental problems. These chemicals form during the water treatment process.
How to Remove It
Activated carbon filtration effectively removes haloacetic acids. Whole-house or point-of-use carbon filters provide comprehensive protection.
Get a Certified SolutionTTHM
ByproductWhat is it?
Total Trihalomethanes (TTHMs) are disinfection byproducts formed when chlorine reacts with organic matter in water. They indicate problems with water treatment or source water quality.
Health Risks
Long-term TTHM exposure is linked to bladder cancer, liver problems, and adverse reproductive outcomes. Pregnant women face increased risk of miscarriage and birth defects.
How to Remove It
Activated carbon filters effectively remove TTHMs and chlorine. A whole-house carbon filtration system provides protection at every tap in your home.

Why Filtration is an Investment in Your Health
Your local water utility meets federal standards, but "legal" doesn't always mean "optimal." The contaminants listed above—even in trace amounts—can accumulate in your body over time.
Protect Your Long-Term Health
Heavy metals and synthetic chemicals found in tap water have been linked to long-term metabolic and immune system issues. Filtering at the source is your first line of defense.
Better Skin & Hair
Unfiltered water often contains chlorine and hardness minerals that strip natural oils from your skin and hair. Pure water can lead to softer skin, shinier hair, and a healthier glow.
Based on Lexington's water profile, these NSF-certified reverse osmosis systems are the most reliable way to remove the contaminants identified above. Choose the option that fits your home.

Frequently Asked Questions for LEXINGTON
Is it safe to shower with Coliform bacteria?
It is generally safe for healthy adults, but avoid swallowing water. Open wounds should be covered.
Can I taste or smell Arsenic in my water?
No. Arsenic is completely odorless and tasteless. Only a lab test can confirm its presence in your water.
What are TTHMs and where do they come from?
TTHMs (Trihalomethanes) are byproducts created when chlorine reacts with organic matter during water treatment. They're linked to cancer.
Does boiling water kill Coliform?
Yes, bringing water to a rolling boil for 1 minute kills bacteria. However, a UV or Chlorine system is required for a permanent solution.
How We Analyze LEXINGTON Water Quality
Official EPA Data
We source all violation records directly from the EPA's Safe Drinking Water Information System (SDWIS), the federal government's official database for public water system compliance.
