The present study was done to evaluate the water purifying property of activated Phyllanthus Emblica wood and Coconut Shell. The groundwater sample was collected from Sangli and Ashta. Activated Phyllanthus Emblica and coconut shell were examined as a natural alternative material of ground water treatment. The water sample was tested for 12Hrs, 20Hrs, and 24Hrs respectively. We examined the hardness of the water sample and found that the hardness of water was reduced up to certain percentage. Hence, the hardness was reduced with increased time up to 24Hrs and as the dosage of material was increased.
