KARACHI, Oct 15: While several deaths caused by waterborne amoeba have been reported in the city, a quality report released on Monday said that all 58 samples of drinking water collected in four towns were ‘non-chlorinated’.

A senior official of the Karachi Metropolitan Corporation said that all the 58 samples — 30 from Baldia Town, 10 from Saddar, eight from Lyari and 10 from Bin Qasim Town — collected from main water lines of the Karachi Water and Sewerage Board on Monday had been found unsatisfactory or with no level of chlorine.Also on Monday, the KWSB collected 81 water samples from 13 towns. Of the 81 samples, four — all collected from Gulberg Town — were termed unsatisfactory due to an absolute absence of chlorine in them.

According to laboratory details, 41 samples had traces, while the presence of chlorine ranging from 0.15 parts per million to 2ppm was confirmed in the remaining 36 samples.

The provincial health department was not satisfied with the results related to piped water chlorination and wanted the KWSB to improve its process of disinfecting water, a source said, adding that Health Minister Dr Sagheer Ahmed clearly said that he did not accept results of the samples showing just traces of chlorine as any quality or chlorinated water.
