   A malfunctioning valve at the water treatment plant in Bowling Green led to a release of an estimated 2,000 gallons of drinking water treatment sludge Monday, state officials said.
   City officials notified the Department of Natural Resources. The sludge reached Buckner Hollow and Noix Creek, which is a tributary of the Mississippi River. The leak affected about 2.5 miles of waterways.
   The release was discovered at 2:30 p.m. Monday and stopped shortly thereafter, officials said. It was not immediately known when the overflow began.
   The department dispatched an investigator from its Macon office to assess environmental effects. Samples of the water were taken and will be tested for by-products of the drinking water treatment process.
   Unlike wastewater sludge, the drinking water treatment sludge that was released consisted primarily of the solids that settled or were filtered out of the lake water used by the city as its source for raw water and carbon from the treatment process.
