The Very Intense Study Area (VISA) Network monitors specific areas of the state that are believed to be highly susceptible to ground water contamination, based on predominant land use and hydrogeology. A VISA well is designed to monitor the effects of multiple sources of contamination on water quality within a segment of the aquifer.

VISA Network wells are sampled for the same analytes as those in the Background Network. The resulting data are statistically compared to like parameters from the Background Network representing the same aquifer segment, in order to determine the effects of land use and site hydrogeology upon the ground water quality. Based on the results of the latter analyses, predictions are made regarding the effects of siting comparable land uses in hydrogeologically similar areas of the state.
