There was no change in concentrations of chloride, dissolved solids, or nitrate in groundwater for more than 50 percent of well networks sampled in a new analysis by the USGS that compared samples from 1988-2000 to samples from 2001-2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.
