Groundwater quality deterioration due to anthropogenic activities has become a subject of prime concern. The objective of the study was to assess the spatial and temporal variations in groundwater quality and to identify the sources in the western half of the Bengaluru city using multivariate statistical techniques.

Urban water demand will increase by 80% by 2050, while climate change will alter the timing and distribution of water. Here we quantify the magnitude of these twin challenges to urban water security, combining a dataset of urban water sources of 482 of the world’s largest cities with estimates of future water demand, based on the Intergovernmental Panel on Climate Change (IPCC)’s Fifth Assessment scenarios, and predictions of future water availability, using the WaterGAP3 modelling framework. We project an urban surface-water deficit of 1,386–6,764 million m³.

The presence of diarrhoeagenic bacteria such as Escherichia coli in drinking water indicates faecal and sewage contamination. Testing the microbial quality of drinking water at source (n = 29) and households (n = 43) of 29 peri-urban villages of Bengaluru city, indicated that 80% and 93% of samples respectively were unfit for human consumption as per WHO standards, i.e. nil E. coli in 100 ml sample. This also indicated that water gets contaminated further at the point-of-use when compared to the source.
