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 30 of the 37 contaminants in your drinking water.
- To filter out 33 of the 37 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
- Atrazine – herbicide
- Barium – health risks in water
- Bromacil – herbicide used for brush control. See: Safety
- Bromochloroacetic acid
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monochloroacetic acid
- Phenanthrene – used in dyes, plastics, pesticides, explosives, and drugs.
- Simazine – herbicide (banned in European Union states)
- 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.
