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.

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.

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 Hilmar'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 HILMAR
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.
Does boiling water remove Arsenic?
No, boiling actually concentrates Arsenic. You need a Reverse Osmosis system to remove it safely.
Does boiling water remove Nitrate?
No, boiling concentrates nitrate levels. Reverse Osmosis or ion exchange systems are required for removal.

How We Analyze HILMAR 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.
