Before reading about the ruling, it may be helpful to listen to NPR journalist Ryan Finnerty's reporting on the case as it was heard by SCOTUS in November 2019.
I somehow missed news of last week's ruling until I saw a link to Steve Hanley's article US Supreme Court Decides Clean Water Act Applies To Groundwater on a site called CleanTecnica, which describes the case in terms of its partisan implications. Journalist Adam Liptak provides a more dispassionate description of the case in Clean Water Act Covers Groundwater Discharges, Supreme Court Rules for the New York Times. Writing for SCOTUS Blog, Lisa Heinzerling dissects the legal philosophies at play.
|Connections between ground water and surface water vary,
but often are this simple.
I use the phrase "is considered a victory" because nobody is quite certain what the ultimate impact of this case will be. As often happens, the Court has returned the case to a lower court with some direction, but that court might have more than the usual latitude in deciphering the court's intent.
Underlying (pun intended, I guess) all of this complication is the fact that Federal jurisdiction over water has in many ways been limited to navigable waterways, a term that originated in the 1899 Rivers and Harbors Act, and whose definition has never engendered a lot of consensus.
For me, this ruling will have been a victory for the environment only if it helps to bring about an end to the dangerous practice of oil extraction through hydraulic fracturing (fracking). The current drop in oil prices will sideline fracking for the next year or two, but legal action will be needed to prevent it from continuing to destroy the quality of ground water in places with minimally accessible petroleum deposits. See my Imagine No Fracking (2012) Non-Oil Futures (2012), and More Than Modified (2014) posts for more on the dangers of pumping toxic solutions into damaged aquifers.
