Physico-chemical and microbiological quality evaluation of groundwater for human domestic consumption in adjoining area of Omti Nallah, Jabalpur (M. P.), India

摘要

Groundwater is one of the most useful water sources. Contamination of such water sources is a big problem creating health hazards. The sewage water from Omti nallah plays a vital role in contaminating the groundwater quality in Jabalpur city, M.P., India. Hence the present study was undertaken to characterize nature (parameters) of groundwater in Jabalpur city, by taking water samples from six different stations locating near to the Omti nallah area. Evaluation of physico-chemical and microbiological parameters of water samples was carried out during March – April 2011. To assess the quality of groundwater, each parameter was compared with the standard desirable limit of that parameter in drinking water as prescribed by BIS 10500-91. The comparison of different parameters spatially showed an increasing pattern of alkalinity, total dissolved solids, total hardness, calcium, fluoride and fecal coliform concentrations and decreasing concentration of dissolved oxygen in the groundwater. It is necessary to apply strong preventions immediately to save groundwater from deterioration in the area around Omti nallah in Jabalpur city.
