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 22 contaminants in your drinking water.
- To filter out 19 of the 22 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Arsenic – health risks
- Barium – health risks
- Bromodichloromethane – health risks
- Chloroform – health risks
- Chromium (total)
- Dibromoacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium
- Total trihalomethanes – byproduct of chlorination*
*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.
