Water is important for sustaining life. Presently the demand of water is increased for drinking, irrigation and industrial purposes. Excessive use of water leads to the depleting of aquifer as well as deterioration of quality. In these days many techniques are available for searching of groundwater and quality establishment. In the present study Geographical Information System (GIS) has been used to study spatial groundwater quality in Kaithal district, Haryana. Kaithal district is located between the latitudes 29°30” North to 30°11 North and longitudes 76°090 East to 76°41 East and covering area 2,317 sq. km. In the study 62 groundwater samples were collected during field in the month of February 2019. All the groundwater samples were analyzed using Field Water Testing Kit prepared by Tamilnadu Water Supply and Drainage Board, Chennai for twelve chemical parameters-pH, alkalinity, hardness, chloride, total dissolved solids, fluoride, iron, ammonia, nitrite, nitrate, phosphate and residual chlorine. Results of chemical analysis of groundwater samples were put in GIS environment and inverse distance weighted interpolation technique applied to get spatial scenario of each chemical parameter in the study area. Chemical results were categorized in desirable, permissible and non-potable drinking water class as per BIS drinking water standards and area under each drinking water class was calculated. In the study area pH covers 97.45% area under desirable and 2.55% area under non-potable, alkalinity is desirable in 0.18% area, permissible in 99.14% area and non-potable in 0.68% area, hardness covers 63.15% area under desirable, 34.94% area under permissible and 1.91% area under non-potable, chloride is desirable in 85.32 % area and permissible in 14.68% area, total dissolved solids cover 0.15% area under desirable, 98.83% area under permissible and 1.02% area under non-potable, fluoride is desirable in 4.79% area, permissible in 18.88% area and non-potable in 76.33% area, iron is desirable in 94.48% area and non-potable in 5.52% area, ammonia covers 55.29% area under desirable and 44.71% area under non-potable, nitrate covers 100% area under non-potable and nitrite, phosphate and residual chlorine cover 100% area under desirable drinking water class. The spatial groundwater quality scenario in the study area is highly useful for planning, monitoring and management of groundwater for drinking purpose.
