Authorities say someone has threatened to poison the water supply in Columbus.
As a precaution, residents are being urged to drink bottled water while state, city and Lowndes County authorities investigate the threat.
Columbus officials said there's been no indication the threat is credible.
The call was reportedly made about 9:00 a.m. Tuesday to the Mississippi Emergency Management Agency office in Jackson.
MEMA director, Robert Latham, said the call was from, "somebody who said they had gotten a call from another individual who said he would actually put something in the water."
Latham said his office always investigates when such threats are made.
