- Haloacetic acids (HAA9) are at extremely high levels: 316x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
- Hexavalent chromium is at high levels: 15x health guidelines.
Let’s look closer at what’s in Gary water.
What’s in Gary water?
Here are the top 5 chemical compounds in Gary water and what health issues they can potentially cause:
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Nitrate – Potential effect: Cancer
- Nitrate and Nitrite – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 12 contaminants analyzed by the Environmental Working Group (ewg.org).
These 6 contaminants are rated as exceeding EWG Health Guidelines.
Does Gary water have Lead contamination?
Yes, Gary has lead in its water. The most recent Lead samples collected from 2016 through 2018 showed concentrations up to 6.0 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 Gary 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 some 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 at least 80% of contaminants in your drinking water.
- Berkey filters can also remove up to 99.99% of Lead in Gary water.
- Brita can filter 4 contaminants and Lead depending on the filter.
- Note: We may receive a commission if you decide to purchase filters through links on this page.
- To filter out All 12 contaminants, consider a Reverse Osmosis water filtration system for your house.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium
- Total trihalomethanes – byproduct of chlorination*
*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.
