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 16 of the 20 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 Walnut Creek water.

  • To filter out 10 of the 20 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.

*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:
