EFFECT OF MONSOON ON GROUNDWATER QUALITY OF JAIPUR DISTRICT, RAJASTHANSUBHASH CHAND JAT, SIVARANJANI S., RAMAVTAR GAUTAM AND AMITAVA RAKSHITAbstract Deterioration of ground water resources has long been a major concern to human society, the aim is to preserve and maintain balanced biological communities and sustainable stream ecosystem health. The sustainable use of ground water resources in India and other countries requires the development of more powerful tools to assess the water quality and health of ground water. The present study area enjoys arid and semi-arid climate with mild winter and long summer days. The area receives rainfall from the southwest monsoon lasting from June to September with a mean annual rainfall of 61.36 cm, 90 to 93 per cent of which is received during June to September and potential evapo-transpiration is about more than annual rain fall. The temperature of the area varies from 4 °C to 45 °C. The physico-chemical analysis of water samples in the study area indicates pH ranged from 7.1 to 8.4 suggesting neutral to alkaline nature of groundwater. The water samples have been collected from different blocks and villages of Jaipur district before and after rainfall season, thirteen parameters have been considered for determining water quality namely pH, EC, total dissolved solids, total hardness, calcium, magnesium, carbonate, bicarbonate, chloride, nitrate, sodium, potassium, phosphorus. The study show the presence of nitrate in the ground water in different water sample varies between 0.45 and 3.77 ppmL-1, but it does not exceeds BIS standard except in one case. |
