According to a New York Times report, 10% of Americans drink water that contains dangerous chemicals or fails to meet a federal health benchmark in other ways. The report found that Charleston, VW, for example, has significant levels of lead, nickel, and other heavy metals, causing- in the worst cases- customers to develop painful rashes and significant loss of tooth enamel. The report also notes wells, both private and public, are often the most dangerous water sources, because they are the least regulated. It should be noted that no distinction was drawn between bored wells, which pull heavily on the water table, and properly constructed drilled wells, which are sealed against surface water. As a water consumer, the bottom line is whether you choose to trust water safety to an outside provider- even the government, or would prefer to take the responsibility yourself.
