The area affected is all of the Edmonson County water district's service area south of Green River except the city of Brownsville and 31-W north of the crossroad.
Officials issued the advisory Tuesday due to main line breaks.
The leak has since been repaired and the tanks are full.
Now water officials say samples are being taken and the results should be back early Thursday afternoon.
Until then a boil water advisory still remains in effect.
