Abstract
The current work aims to assess the Water Quality Index of the supplied tanker water in Kudlu village of Bangalore, India. The area is heavily dependent on water supplied by tankers, since groundwater is scarce. Water tankers supplying water in the area claim the supplied water to be of drinkable quality. Water samples were collected from four tankers supplying water in the area for a period of 18 months, from September 2021 to February 2022. These samples were subjected to physicochemical and microbiological characteristic analysis. Heavy metals were also characterized for the collected samples. Water quality indices was calculated using 18 parameters, namely chlorine, pH, alkalinity, cyanuric acid, total hardness, conductivity, temperature, sodium, potassium, total dissolved solids, calcium, magnesium, heavy metals, such as iron, zinc, lead, arsenic, copper, and cadmium. The results indicate that the calculated WQI for most of the months is > 50, hence unsuitable for drinking purposes. Microbiological contamination with the bacteria E. coli was also noted for some samples for a few months. Hence, the water supplied by the commercial tankers in this area is not suitable for direct consumption and must be treated by boiling or filtering before usage. Correlation parameters were also calculated for the physicochemical parameters for all the average values obtained for all the collected water samples.
