Abstract

To monitor the downward movement of distillery effluent and possible ground water contamination, piezometers were installed at 1 metre depth in the Cumbu Napier hybrid grass field at Research and Development Farm of M/s. Bannari Amman Sugars Ltd., Ealur, Erode district, Tamil Nadu, during August 2009 to July 2010. Treatments involved are distillery spentwash @ 37.5 and 50 kilo litres per ha at full and split dose along with recommended dose of fertilizers. Leachate was collected from piezometers at 4th week after planting and subsequent collections at the time of harvesting from 12th week after planting to 52nd week after planting and leachate samples were analyzed for various parameters. The results indicated that there was an increase in pH, EC, COD, anions and cations content due to the application of BDS over the recommended dose and were within the critical limits and have not influenced the ground water and there is no possibility of pollution by BDS application.
