Contaminants in Well and City Water
What is a water contaminant?
- Technically, anything that is NOT water that is IN water is a contaminant
- For example, iron, sodium, even Kool-Aid, are contaminants
- Some contaminants are harmful and some are just a nuisance
No single unit will remove every contaminant
- Don’t confuse conditioned water, softened water or neutralized water with “purified” water.
- For most residential households, a combination of an Ultra Violet Light System for bacteria and a Reverse Osmosis or an Always Fresh filtration system would achieve safe, potable water
The most common water contaminants in Connecticut are:

Frequently Asked Questions about Contaminants
How do I know I have contaminants in my water?
- Most of the time, you don’t.
- Most contaminants are colorless, odorless and tasteless
- Testing is the only way to really know
There are so many things to test for, what should I do first?
- City water is regulated by the Environmental Protection Agency
- Go to www.epa.gov and search for your county
- Private wells are not regulated
- The CT Dept of Public Health recommends a yearly test for:
- Total Coliform Bacteria
If you have children, test for fluoride and lead
