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 27 of the 34 contaminants in your drinking water.
- Berkey filters can also remove up to 99.99% of Lead in Frisco water.
- Brita can filter 16 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 30 of the 34 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:
- Arsenic – health risks
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Cyanide – exposure limits
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monobromoacetic acid
- Monochloroacetic acid
- Selenium – health risks
- 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.
