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 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.

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 Fremont'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 FREMONT
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.
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.
