Following WHO guidelines on water safety, QMRA were performed was to estimate burden of disease from E. coli from water vending machines. Triplicate drinking water samples from water vending machines were collected from six sampling areas around the city, analysed for E. coli, information of health symptoms and daily water intake was obtained from 121 respondents by questionnaires. The results indicated the highest numbers of E. coli levels were found in Seri Serdang (45-68â¯CFU/100â¯mL) and Taman Pinggiran Putra (45-62â¯CFU/100â¯mL). Escherichia coli levels in drinking water samples from water vending machines obtained from Seri Serdang, Taman Pinggiran Putra, Taman Equine, Balakong and Serdang Jaya exceeded both Malaysian Drinking Water Quality and WHO Drinking Water Quality guidelines.
