An Iron-Clad Guarantee?
Moreover, while most of the stored, untreated water would be contained 1,000 feet underground in a layer of salty, brackish water, about 30 percent of the untreated water would drift away. Whether it could find its way into the pure aquifer water above and below it by working its way through confining layers remains in question. If all that doesn't create an uneasy feeling about the future of ...
