What is the water quality like in Fontana, CA?
Let’s dive deeper into what’s in Fontana water.
What’s in Fontana water?
Here are the top 5 chemical compounds in your 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 29 contaminants analyzed by the Environmental Working Group (ewg.org).
12 of these contaminants are rated as exceeding EWG Health Guidelines.
See the What Can You Do? section below for all of the contaminants you can filter out and how to do it.

Conclusion – What Can You Do?
Information about water quality can be surprising.
But there’s no reason to lose hope. There are things you can do in your household as well as things you can do at a community level.
In Your Household:
- Use Berkey filters with activated carbon to filter out 24 of the 29 contaminants in your drinking water. (Berkey Light and Travel Berkey are the only types available in California.)
- To filter out 25 of the 29 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:
- Arsenic – health effects in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- DBCP – soil fumigant causing male sterility at high exposure levels.
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monobromoacetic acid
- Perchlorate – used as oxidizers in propellants for rockets, fireworks, and highway flares. Also used to control static electricity in food packaging.
- Tetrachloroethylene – dry cleaning fluid. See: Health and safety
- 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.
In Your Community:
Contact your local government officials and put pressure on them to invest in cleaner waterways and upgraded city water filtration and treatment.
