UPDATE: Miss. seeks high court help in Memphis water fight

NASHVILLE, Tenn. — Mississippi wants the U.S. Supreme Court to decide whether Tennessee’s largest city is pumping too much water out of an aquifer shared by the two states.

This week’s filing claims heavy pumping by Memphis has created a “cone of depression” in the aquifer that is siphoning more than 24 million gallons of ground water out of northern Mississippi.

Mississippi claims Memphis has wrongfully taken up to 22 percent of its water supply from its neighbor since 1965. The petition seeks an order for Tennessee, Memphis and the city’s water utility to stop the practice and pay more than $1 billion in damages.

Memphis utility officials have argued that their wells are not designed to pull water from Mississippi.
