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 19 of the 24 contaminants in your drinking water.
  • Berkey filters can also remove up to 99.99% of Lead in Norman water.
  • Brita can filter 7 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 22 of the 24 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:
    • Antimony
    • Arsenic – health risks
    • Barium – health risks in water
    • Bromodichloromethane – health risks in drinking water
    • Chloroform – side effects
    • Chromium (total)
    • Cyanide – exposure limits
    • Dibromochloromethane
    • Dichloroacetic acid
    • Fluoride
    • Haloacetic acids – chlorination byproduct*
    • Hexavalent chromium – health effects
    • Molybdenum
    • Nitrate
    • Nitrite
    • Radium
    • Selenium – health risks
    • Strontium
    • Total trihalomethanes – byproduct of chlorination*
    • Uranium

*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.
