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.

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 SolutionLead
NeurotoxinWhat is it?
Lead is a toxic heavy metal that leaches from aging pipes, solder, and fixtures. It was banned from plumbing materials in 1986, but millions of older homes and water systems still contain lead service lines.
Health Risks
Even low levels of lead in blood affect IQ, attention span, and behavior in children. In adults, lead exposure causes high blood pressure, kidney damage, and reproductive problems. There is NO safe level of lead exposure.
How to Remove It
Boiling does NOT remove lead - it actually concentrates it. You need a certified NSF/ANSI 53 filter or Reverse Osmosis system to effectively remove lead from drinking water.
Get a Certified SolutionUranium
RadioactiveWhat is it?
Uranium is a radioactive heavy metal that occurs naturally in certain rock formations and groundwater. Mining activities can also increase uranium levels in local water supplies.
Health Risks
Uranium damages kidneys and increases cancer risk with prolonged exposure. As a radioactive element, it poses both chemical toxicity and radiation hazards to your body.
How to Remove It
Standard filters cannot remove radioactive elements. You need a specialized Reverse Osmosis or ion exchange system certified for radionuclide removal.
Get a Certified SolutionNitrate
AgriculturalWhat is it?
Nitrates enter water from fertilizer runoff, septic systems, and animal waste. Agricultural areas are particularly susceptible to nitrate contamination of groundwater.
Health Risks
High nitrate levels are extremely dangerous for infants, causing 'blue baby syndrome' (methemoglobinemia) which restricts oxygen in the blood. Pregnant women are also at elevated risk.
How to Remove It
Carbon filters do NOT remove nitrates. Reverse Osmosis, ion exchange, or distillation systems are the only effective home treatment methods for nitrate removal.
Get a Certified SolutionFluoride
MineralWhat is it?
While fluoride is added to many water supplies for dental health, some areas have naturally high fluoride levels that exceed safe thresholds. Excessive fluoride poses health risks.
Health Risks
High fluoride exposure causes dental fluorosis (mottled teeth) and skeletal fluorosis (bone and joint damage). Children are particularly vulnerable during tooth development.
How to Remove It
Reverse Osmosis is the most effective method for fluoride removal. Activated alumina or bone char filters can also reduce fluoride to safe levels.

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 Norman'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 NORMAN
Does boiling water remove Lead?
NO. Boiling water actually concentrates lead levels as water evaporates. You must use a certified filter.
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.
Why is Nitrate dangerous for babies?
Nitrate reduces oxygen in the blood, causing 'blue baby syndrome' (methemoglobinemia). Infants under 6 months should not drink nitrate-contaminated water.

How We Analyze NORMAN 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.
Strict Grading
Our grading system prioritizes public health. We distinguish between critical contaminants (Lead, Arsenic, PFAS) and administrative violations like late paperwork - because your health matters more than bureaucracy.
Independent Analysis
We are not affiliated with any water utility, government agency, or filter manufacturer. Our analysis is independent and designed to help you make informed decisions about your family's water safety.
