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 23 of the 30 contaminants in your drinking water.
  • Berkey filters can also remove up to 99.99% of Lead in Mission water.
  • Brita can filter 13 (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 27 of the 30 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 – irritant to the eyes and respiratory tract.
    • Aluminum
    • Arsenic – health risks
    • Barium – health risks in water
    • Bromodichloromethane – health risks in drinking water
    • Bromoform
    • Chlorite
    • Chloroform – side effects
    • Chromium (total)
    • Cyanide – exposure limits
    • Dibromoacetic acid
    • Dibromochloromethane
    • Fluoride
    • Haloacetic acids – chlorination byproduct*
    • Hexadecanoic acid (palmitic acid) – increased risk of heart disease
    • Hexavalent chromium – health effects
    • Nitrate
    • Radium
    • Selenium – health risks
    • Strontium
    • Total trihalomethanes – byproduct of chlorination*
    • Trichloroacetic acid
    • 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.
