Portability of water obtained through boring in Karachi

This study was carried out to detect the faecal contamination in water obtained from indigenously designed boring facilities. The presence of escherichia coli [major indicator of faecal contamination] was detected after performing the coliform test along with biochemical studies in 32 boring water samples out of 60 samples collected from various localities of Karachi city. Its presence in underground water resources definitely indicates the possible presence of water-borne pathogens
