Hydrochemical characteristics of ground water at Makrana, Nagaur, Rajasthan (India): a case study.

: An investigation was carried out to find out the subsurface water quality at eighteen different sites at Makrana, Nagaur, Rajasthan (India) keeping in view its utilization for portability and domestic use. Various physico-chemical parameters, such as pH, free CO2, TDS, hardness, total alkalinity, chlorides, electric conductivity, calcium, total dissolved solids, magnesium, phosphate, nitrate and sulphate were examined through the water analysis. The results were compared with the standard values prescribed by the Bureau of Indian Standards (BIS) and World Health Organization(WHO). The results indicate that the water of tube wells and hand pumps of the city as well as nearby industrial areas has higher concentrations for all physico-chemical parameters. Therefore, proper disposal of marble slurry after treatment, and recycling of wastewater along with periodical monitoring of sub-surface water are very important as a part of management strategies for the Makrana area. Such aspects have been discussed in this paper.
