How many wells were sampled and in what areas?
Samples of ambient ground water from almost 3,500 wells in 98 aquifer studies were analyzed for volatile organic compounds (VOCs). The wells were located throughout the conterminous United States as well as Alaska and Hawaii. In addition, results of samples from about 2,400 domestic wells and more than 1,100 public wells were compiled to assess VOC occurrence. These domestic and public wells also were distributed nationwide.
