Researchers Identify US Counties With Worst Drinking Water Violations

Standing out among the top 10 such regions was Wyoming County, West Virginia, whose public water utility boasted the highest number of infringements in a single water system, according to the study, published Tuesday in international journal Risk Analysis.
