More than five buildings on Chitrakar Dhurandhar Marg,Khar West,have been receiving polluted water from Brihanmumbai Municipal Corporation (BMC) for over a fortnight. What has alarmed residents is the presence of worms and insects in the water in the last couple of days. Sanjivani Kashikar,a resident of Naad Brahma building on CD Marg,said the tap water smelled foul at times in the past three months,but the problem aggravated in the last fortnight. Last week,I complained to the BMC. Earlier,I thought there was a problem with my pipeline,but later learnt that residents from nearby buildings,too,were getting dirty water, she said. Kashikar has complained to the BMC twice. On Wednesday,her domestic help found worms in the purifiers filter slot. Swati Sah,another resident,said the tank was cleaned a month ago so chances of dirt accumulating in it were slim. I am sure BMCs water supply is contaminated with sewage. The water has been noticeably stinky for the last three days, she said. R D Bhendkhale,assistant engineer,water works department in the H West wards office,said a team was sent to take samples on Thursday. We have to ascertain the level of contamination. This will take a few more days, he said. The samples are sent to G North ward (Dadar) office for inspection. M R Boudhankar,health officer,H West ward,said the analysis takes 10-15 days,after which the water is classified as fit,unfit or containing Escherichia coli. If the water has E coli bacteria,then it is flushed out through a pump. CD Marg has never been on the fix spots list for water contamination in H West ward. Fix spots are those areas that frequently report water contamination and have to be monitored regularly. Boudhankar said this was the first time such a complaint was received from this area. tabassum.barnagarwala@expressindia.com Contamination level rises: Report MUMBAI: Water contamination levels in the city have risen in the past year,says BMCs environment status report for 2012-2013.
