Ground water arsenic contamination is a well known health and environmental problem in Bangladesh.Sources of this heavy metal are known to be geogenic, however, the processes of its release into groundwater are poorly understood phenomena.In quest of mitigation of the problem it is necessary to predict hbl5266ca probable contamination before it causes any damage to human health.

Hence our research has been carried out to find the factor relations of arsenic contamination and develop an arsenic contamination prediction model.Researchers have generally agreed that the elevated concentration of arsenic is affected by several factors such as soil reaction (pH), organic matter content, geology, iron content, etc.However, the variability of concentration within short lateral and vertical intervals, and the inter-relationships of variables among themselves, make blackmores ache relief focus review the statistical analyses highly non-linear and difficult to converge with a meaningful relationship.

Artificial Neural Networks (ANN) comes in handy for such a black box type problem.This research uses Back propagation Neural Networks (BPNN) to train and validate the data derived from Geographic Information System (GIS) spatial distribution grids.The neural network architecture with (6-20-1) pattern was able to predict the arsenic concentration with reasonable accuracy.
