NERC EDS Environmental Information Data Centre 10.5285/9bc3dce7-7c2b-49dd-9b76-819267d7a352 This dataset comprises field sensor physicochemical and optical/fluorescence measurements, as well as laboratory microbiological and chemical analysis, for urban surface water samples. Samples were collected at different locations throughout the urban area of Kolkata, with the latitude and longitude of all sample location provided within the spreadsheets. Samples/data were collected across three separate field surveys undertaken in June 2018 (file 1), March 2019 (file 2) and December 2019 (file 3). This dataset forms a case study of the water quality of three different types of urban surface freshwaters within the city of Kolkata, India. This case study was created to deploy a prototype multichannel fluorimeter and assess its ability to identify waters with a high bacterial load and biological contamination events through the use of Peak T fluorescence.

Field equipment was calibrated as necessary, with handheld meters being calibrated with the correct reagents weekly. The fluorimeters were calibrated before the field surveys by the manufacturer and checks were carried out before each sampling day to ensure baseline values were as expected (0 QSU or 0 FNU in DI water). Data here is provided as an average with a standard deviation to represent 1 minute (n =-60) of sampling time. The survey conducted in December 2019 provides fluorescence data as a single value due to errors in data logging. Microbiological analysis was conducted within 6 hours of the sample collection, whilst some of the nutrient analysis was conducted up to 3 weeks after samples were collected in India. These were analysed in the UK but standard preparation, storage and transportation procedures were followed.
