In Your Household:

    • Berkey filters can also remove up to 99.99% of Lead in Visalia water.

  • To filter out 28 of the 32 contaminants, consider a Reverse Osmosis water filtration system for your house.

*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.
