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 22 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 Salinas water.
- Brita can filter 9 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 25 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:
- 1,4-Dioxane – “Exposure may cause damage to the central nervous system, liver and kidneys.”
- Arsenic – health risks
- Barium – health risks in water
- Chromium (total)
- Hexavalent chromium – health effects
- MTBE – fuel additive to increase knock resistance and reduce unwanted emissions.
- Radon – Health risks
- 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.
