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 filters can also remove up to 99.99% of Lead in Green Bay water.
  • Brita can filter 12 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.”
    • Aluminum
    • Antimony
    • Arsenic – health risks
    • Barium – health risks in water
    • Bromate
    • Bromide
    • Bromodichloromethane – health risks in drinking water
    • Bromoform
    • Cadmium – poisoning can lead to weak and brittle bones.
    • Chloroform – side effects
    • Dibromoacetic acid
    • Dibromochloromethane
    • Dichloroacetic acid
    • Fluoride
    • Haloacetic acids – chlorination byproduct*
    • Hexavalent chromium – health effects
    • Molybdenum
    • Nitrate
    • Radium
    • Silver
    • 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.
