Contaminant Analysis
View Data SourcesColiform
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.

RadioactiveWhat is it?
Radium is a naturally occurring radioactive element found in underground rock formations. Deep wells and groundwater sources are most susceptible to radium contamination.
Health Risks
Radium accumulates in bones and can cause bone cancer and leukemia. Long-term exposure through drinking water significantly increases lifetime cancer risk.
How to Remove It
Radioactive contaminants require specialized treatment. Ion exchange or Reverse Osmosis systems certified for radionuclide removal are necessary for safe drinking water.
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.

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 Colchester'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 COLCHESTER
Is it safe to shower with Coliform bacteria?
It is generally safe for healthy adults, but avoid swallowing water. Open wounds should be covered.
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 dangerous is Radium in drinking water?
Radium accumulates in bones and can cause bone cancer and leukemia. Long-term exposure significantly increases cancer risk.
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.
