Drinking Water

The United States has one of the most reliable and safest drinking water networks in the world. This is thanks in large part to federal regulation such as the Safe Drinking Water Act, passed in 1974. However, federal regulation doesn’t cover all drinking water sources, and many sources (such as cisterns and wells) aren’t required to be tested. This can lead to serious issues with local drinking water quality, and many aren’t aware of how severe some of these issues can be.

For example, here in Rusk County:

  •  An estimated 40% of Rusk County residents drink well water from federally unregulated sources. 

  • Only 16% of well owners have their water tested. 
  • 47% of private wells could be contaminated with one or more contaminants, so having well water tested is very important
