Contaminant Analysis
View Data SourcesUranium
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.

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.

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 Coyle'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 COYLE
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.
Is Uranium in my water radioactive?
Yes, Uranium is radioactive. Long-term exposure through drinking water increases cancer risk and can damage kidneys.
Does boiling water remove Nitrate?
No, boiling concentrates nitrate levels. Reverse Osmosis or ion exchange systems are required for removal.
Do pitcher filters work?
Most standard pitchers are cosmetic and do NOT remove serious contaminants like Lead, Arsenic, or Bacteria. You need an NSF-certified system.
How We Analyze COYLE 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.
