"North Carolina did not properly police public water supplies or private wells. Thousands of systems were not obeying laws requiring them to test their water and clean up contamination. Hundreds did not have a certified operator. While state regulators levied fines, they usually did not collect. The story also revealed problems with private wells that put two million North Carolinians at risk. The state enacted well construction standards years ago, but didn't enforce them. Two-thirds of the state's 100 counties didn't either. There was no state law in North Carolina requiring tests of private well water, and few counties require such tests."
