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 15 of the 18 contaminants in your drinking water.
- To filter out 16 of the 18 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:
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*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.
