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 28 contaminants in your drinking water. (Berkey Light and Travel Berkey are the only types available in California.)
- Berkey filters can also remove up to 99.99% of Lead in Chino Hills water.
- Brita can filter 14 (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 26 of the 28 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 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
- Monobromoacetic acid
- Monochloroacetic acid
- Selenium – health risks
- 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.
