WATER management Authority (WARMA) is investigating the source of the sky-blue colour found in boreholes and shallow wells in Garden House area in Lusaka West.
WARMA in collaborating with the Department of Water Resources Development (DWRD) and Ministry of Health is investigate the actual affected water by using a fluorimeter and contouring of the landscape to detect the possible source of the sky-blue color in the water.
WARMA Public Relations Officer Joshua Kapila said they had done preliminary investigations on the recent suspected contamination of water in the boreholes and shallow wells.
Mr Kapila told the Daily Nation that the specific zone that was suspected to have been contaminated was isolated to establish the extent of the problem.
He said the water from the boreholes was discovered to be sky blue in colour, but had no discharge.
“WARMA carried out preliminary on-site tests and the results indicated that the sky-blue color in the water cleared upon addition of Chlorine, which is a bleaching agent.
‘The disappearance of the sky-blue color after addition of chlorine is an indication that there is high probability of dyes in the water,” he said.
He said WARMA was going to investigate the actual affected water by using a fluorimeter and contouring of the landscape to detect the possible source of the sky-blue color in the water.
He has assured the general public that key parameters of the said water was in compliance with the Zambia Bureau of Standards and within allowable limit for Drinking Water despite the coloration, as evidenced by no indication of hazardous reports to human health from the area as a result of consuming the said water.
