Groundwater is predominantly used for domestic water consumption in urban territory, which includes Bhubaneswar town, grouped under the smart city of Odisha, India. Although there is provision of pipe water supply, the population of the city is increasing in a tremendous way, and to fulfil the demand for water supply as per SDG 6, we have given importance to groundwater sources. The rapid urbanisation leads to an increase in municipal waste, an increase in industrialisation, development in health care facilities, and unregulated vehicle cleaning sites discharging contaminated water to adjacent drains or water bodies. Due to the above reason, the quality of groundwater has been deteriorating gradually. So, to have a clear idea about the status of groundwater quality data of Bhubaneswar city for the last 18 years, i.e. from 2000 to 2018, it has been collected from the National Water Informatic Centre (NWIC). In this perspective, there is a need for statistical analysis of the present available data to know the trend of groundwater quality parameters. This research has focused on a detailed analysis of groundwater parameters such as chloride, fluoride, iron, and sulphate by using Mann–Kendall and Sen’s Slope method. From the collected sample, it is observed that iron concentration of 3.562 mg/L at Patia in the year 2015, Kapilaprasad areas observed 2.221 mg/L. Fluoride is detected in the range of below 0.5 mg/L at the three designated sites, such as Patia, Bhubaneswar-1, and Kapilaprasad.

摘要

Groundwater is predominantly used for domestic water consumption in urban territory, which includes Bhubaneswar town, grouped under the smart city of Odisha, India. Although there is provision of pipe water supply, the population of the city is increasing in a tremendous way, and to fulfil the demand for water supply as per SDG 6, we have given importance to groundwater sources. The rapid urbanisation leads to an increase in municipal waste, an increase in industrialisation, development in health care facilities, and unregulated vehicle cleaning sites discharging contaminated water to adjacent drains or water bodies. Due to the above reason, the quality of groundwater has been deteriorating gradually. So, to have a clear idea about the status of groundwater quality data of Bhubaneswar city for the last 18 years, i.e. from 2000 to 2018, it has been collected from the National Water Informatic Centre (NWIC). In this perspective, there is a need for statistical analysis of the present available data to know the trend of groundwater quality parameters. This research has focused on a detailed analysis of groundwater parameters such as chloride, fluoride, iron, and sulphate by using Mann–Kendall and Sen’s Slope method. From the collected sample, it is observed that iron concentration of 3.562 mg/L at Patia in the year 2015, Kapilaprasad areas observed 2.221 mg/L. Fluoride is detected in the range of below 0.5 mg/L at the three designated sites, such as Patia, Bhubaneswar-1, and Kapilaprasad. At the 0.05 significance level, the Mann–Kendall test shows a downward trend, but even at the 5% confidence interval, the Sen’s slope shows a non-positive slope. A little more troubling situation involves the concentration of fluoride in the groundwater quality at Kapilaprasad. Even at the 5% confidence interval, the Sen’s slope shows a non-positive slope, contrasting to the Mann–Kendall test’s decreasing trend at the 0.1 significance level. Most of the trace element concentrations are found below the detection limit and permissible limit of WHO.
