The National Ground Water Association (NGWA) published a law column from their Water Well Journal on an upcoming Supreme Court Case that could dramatically impact groundwater deposits throughout the US. Mississippi is arguing that groundwater levels underlying Mississippi have been unduly lowered by usage in Tennessee thereby depriving Mississippians of their resource, and that the definition of the aquifer is legally distinguishable from a river. Tennessee is arguing that an aquifer is an interstate resource. The authors, Scott M. Doran, Esq. and William J. Levendusky, Esq. do not anticipate that the ruling could affect private well operators but they caution that it is still too soon to tell. A decision is not expected before early 2017.
