Water is essential to life. The availability of safe drinking water is a fundamental amenity for passengers at railway stations in India. The Indian railway network is the fourth largest network in the world, spanning 65,000km with 7,083 railway stations, after the USA (250,000 km), China (100,000 km), and Russia (85,500 km). As the number of people choosing railways as a mode of transport has increased significantly in recent days, it is crucial to evaluate the tap water quality at railway stations. Therefore, the objective is to evaluate the physiochemical parameters of drinking water provided at railway stations between Thiruvananthapuram and Nagercoil and to determine its suitability for consumption.
