“…Water is the fundamental key to life (Chowdhury et al 2022 ). The rapid growth of population, industrialisation, and anthropogenic activities have resulted in poor drinking water quality (Ramapriya and Elango 2022 ; Darko et al 2021 ; Faroque and South 2021 ). The availability of safe drinking water is one of the minimum passenger amenities at the railway stations in India (Pravithra 2018 ).…”

Availability of safe drinking water at the railway stations is a basic passenger amenity. To maintain the quality of drinking water, the Ministry of Railways, Government of India, follow the Uniform Drinking Water Quality Monitoring Protocol, 2013, with a benchmarking standard of Bureau of Indian Standards, 2012. The quality of drinking water varies from state to state, including station to station, due to the diversified regional structure of the country. The regional structure of Tripura, Northeastern state of India, is unique for its Tilla-Lunga topography, where 27 railway stations provide passenger services, including safe drinking water of heterogeneous quality. The present study aims to assess and develop a model of drinking water quality at the railway stations of Tripura, India, with a possible strategic solution. Multivariate statistical tools like multiple regression analysis, principal component analysis, and cluster analysis have been used. Weighted Arithmetic Water Quality Index (WAWQI) and Entropy Weighted Water Quality Index (EWWQI) have been applied to assess the drinking water quality of the railway stations of Tripura. It has been observed that several physical ( r = 0.42, p -value = 0.064), chemical ( r = 0.31, p -value = 0.047), and biological ( r = 0.47, p -value = 0.077) parameters of drinking water are positively correlated with each other, whereas chloride ( λ = 2.98), E. coli ( λ = 2.13), turbidity ( λ = 1.72), fluoride ( λ = 1.49), and iron ( λ = 1.08) are most significant water quality parameters in the railway stations of Tripura. The WAWQI and EWWQI classified the drinking water of 55.55% and 85.19% of railway stations as good for drinking, respectively. Drinking water quality can improve 55.55% to 81.48% by removing iron content from the water. Physiography and land use patterns of surrounding areas of railway stations influence drinking water quality. Elevation and urbanisation have significant negative correlation (− 0.438 and − 0.441 at 5% level) with drinking water quality. Policy-practice interference has been analysed, and passenger satisfaction with drinking water has been measured for the bottom-up planning approach. Through content analysis, a few technical suggestions have been made to improve the physio-chemical and biological properties of drinking water at the railway stations of Tripura.

“…Contaminated environment due to waste disposal is a serious threat to health and the wider environment. It was not only direct contamination that resulted in the death of this lifeline, but also the combined effects of urbanization and industrialization (Faroque & South, 2021).…”

Water pollution is a scientific study of environmental chemistry on the sources, impacts and fate of chemicals in the aquatic environment, as well as the effects of human activities on them. As a student, you are required to have broad insight and knowledge, especially in dealing with environmental problems in society, by creating a caring character of the environment and finding solutions as an effort to overcome these problems. The purpose of this study is to produce educational materials in the form of additional e-books about water pollution, raising real problems that exist in the surrounding community. In addition, feasibility test and student responses were also measured against the Electronic Supplement on Water Pollution Equipment. The method employed in this study is R&D with the ADDIE model. Research data were collected through speaker and student interviews, due diligence questionnaires and student response questionnaires. The results of the feasibility test conducted by the expert validator on the Electronic Supplementary Book on Water Pollution Material show that the feasibility test for material, language and graphics is 1.00 with a very high validity category. The results of student responses to the Electronic Supplement Book on Water Pollution Material in the limited trial produced a percentage of 86% in the very good category and field trials produced a percentage of 93%.

“…Besides AMD, the leaching of domestic wastes also leads to the contamination of water. This pollution can be worse when the area experiences heavy rainfall and surface runoff simultaneously (Faroque & South, 2022 ). In general, AMD forms during the mining of iron and other ores all over the world (Sahoo et al, 2020 ).…”

Mining activities in the Chini Lake catchment area have been extensive for several years, contributing to acid mine drainage (AMD) events with high concentrations of iron (Fe) and other heavy metals impacting the surface water. However, during the restriction period due to the COVID-19 outbreak, anthropogenic activities have been suspended, which clearly shows a good opportunity for a better environment. Therefore, we aimed to analyze the variation of AMD-associated water pollution in three main zones of the Chini Lake catchment area using Sentinel-2 data for the periods pre-movement control order (MCO), during MCO, and post-MCO from 2019 to 2021. These three zones were chosen due to their proximity to mining areas: zone 1 in the northeastern part, zone 2 in the southeastern part, and zone 3 in the southern part of the Chini Lake area. The acid mine water index (AMWI) was a specific index used to estimate acid mine water. The AMWI values from Sentinel-2 images exhibited that the mean AMWI values in all zones during the MCO period decreased by 14% compared with the pre-MCO period. The spatiotemporal analysis found that the highest polluted zones were recorded in zone 1, followed by zone 3 and zone 2. As compared with during the MCO period, the maximum percentage of increment during post-MCO in all zones was up to 25%. The loosened restriction policy has resulted in more AMD flowing into surface water and increased pollution in Chini Lake. As a whole, our outputs revealed that Sentinel-2 data had a major potential for assessing the AMD-associated pollution of water.
