130-Trace Element Concentration Levels from Ash Pond in Semi-Infinite Aquifer.

Abstract

Distribution of trace elements concentration levels due to leaching from ash pond in semi-infinite aquifer has been studied. Analytical solution has been obtained for predicting the trace elements concentration levels by applying Laplace Transformation Technique (LTT). Initially aquifer is not supposed to be solute free and it is of homogeneous nature. Source concentration at the origin of the aquifer is considered function type which gives more realistic results. Sinusoidal form of groundwater velocity has been considered and it has been observed that sinusoidal form of seepage velocity represents the seasonal variation in tropical regions. Trace elements concentration levels at various positions have been discussed keeping in the view of Bokaro Thermal Power Station (BTPS) which is located in the bank of Damoder river, Jharkhand.
