?EVALUATION OF SHALLOW GROUNDWATER QUALITY IN URBA~ AREAS OF KARACHI (PAKISTAN)-INORGANIC NUTRIENTS AND BACTERIAL CONTAMINATION
Keywords:
Groundwater contamination, Inorganic nutrient, Faecal coliformAbstract
A total of 193 groundwater samples, collected from Karachi-urban areas, were analysed to determine the concentrations of
nitrate, nitrite, ammonia andbacterial densities (coliformand faecalcoliformbacteria). From nitrogen component view point
groundwater quality ofKarachi isacceptablefor humanconsumption. However.coliform bacteria were higherin 83% samples
than the WHO permissiblelimit.The inorganic nitrogen andbacteriologicalcontamination levels suggest that the groundwater
quality is mainly affected by wastewater.
