The quality of water resources is a subject of concern. The health and happiness of the human beings are closely tied up with the quality of the water used for consumption where the per capita consumption of water is an index of quality of life of the people as well as their economic and social condition. Two major sources of drinking water are groundwater and surface water. In India groundwater is the major source of drinking water with 85% of the population dependent on the same. Due to various natural and anthropogenic factors, the groundwater is getting polluted because of deep percolation from intensively cultivated fields, disposal of hazardous wastes, liquid and solid wastes from industries, sewage disposal, and surface impoundments. The risk of drinking water is rising rapidly in the developing countries. Millions of people all over the world particularly in the developing countries are losing their lives every year from water borne diseases like cholera, typhoid, bacillary dysentery, infectious hepatitis, leptospirosis, giardiasis, and gastroenteritis. Similarly, the purpose of our study is to recognize the groundwater contaminate zone in Churu district the help of GIS.
