Most of their 25 contaminants have cancer-causing attributes.
- Arsenic is at extremely high levels: 113x health guidelines.
- Chloroform is at very high levels: 59x health guidelines.
- Haloacetic acids (HAA5) are at extremely high levels: 202x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 477x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
- PFOA is at extremely high levels: 1,429x health guidelines.
- PFOA is considered a “forever chemical” by the EPA and is being studied extensively.
Let’s look closer at what’s in Bloomington water.
What’s in Bloomington water?
Here are the top 5 chemical compounds in Bloomington water and what health issues they can potentially cause:
- Arsenic – Potential effect: Cancer
- Bromodichloromethane – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 25 contaminants analyzed by the Environmental Working Group (ewg.org).
15 of these contaminants are rated as exceeding EWG Health Guidelines.
Does Bloomington water have Lead contamination?
Yes, Bloomington has lead in its water. The most recent Lead samples collected from 2015 through 2017 showed concentrations up to 3.9 parts per billion (ppb).
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be removed.

What Can You Do?
Information about water quality in Bloomington can be surprising.
But there are things you can do in your home to clean up your water.
To Remove Lead and Other Contaminants In Your Home:
There is one solution that beats Brita, PUR, and expensive whole house systems.
- It costs less per gallon.
- Needs fewer filter changes.
- And it doesn’t make your water taste weird.
- Use Berkey filters with activated carbon to filter out the majority of contaminants in your drinking water.
- To filter out 23 of the 25 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Arsenic – health risks
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Dibromoacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Perfluorooctanoic acid (PFOA)
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
