AbstractGroundwater is a vital freshwater resource for various uses, including drinking, irrigation, and industry needs. The increasing dependence of India on groundwater due to dwindling surface water sources and climate extremes has led to concerns about its availability and quality. This study focuses on the groundwater quality and associated human health risks in the West Medinipur district of West Bengal, India. The region, situated between the Kangsabati and Subarnarekha rivers, faces challenges from anthropogenic activities such as agricultural practices and industrial pollution. A comprehensive analysis of physicochemical parameters was conducted on well water samples collected during the monsoon and post‐monsoon periods. The study examined the suitability of groundwater for drinking and irrigation purposes. Water quality indices were calculated to assess its fitness for human consumption. Despite several parameters meeting the water quality standards, elevated iron (Fe) and ammonia (NH4+) levels were observed, potentially impacting groundwater use for drinking. Similarly, groundwater's suitability for irrigation was evaluated based on parameters like sodium adsorption ratio (SAR) and sodium percentage (Na%). The groundwater types dominated by magnesium bicarbonate and the quality could affect soil structure and crop productivity in certain areas. The elevated levels of Fe and NH4+ showed potential human health risks, indicating the need to mitigate adverse effects on human well‐being through appropriate policy and other interventions. The study highlights the complexity of groundwater quality in the study area. It underscores the necessity for comprehensive water policy and management strategies to safeguard water resources and human health in rural India. The findings emphasize the importance of ongoing monitoring and intervention measures to ensure the sustainability and safety of groundwater for present and future generations.

AbstractTransdisciplinary approaches in water are important to ensure water security to everyone around the world. Recently, Young Water Professionals (YWPs) training was carried out to impart learning in transdisciplinary approaches. Besides online workshops and lectures, the training program included the Situation Understanding and Improvement Project (SUIP). Through SUIP, YWPs were able to implement the transdisciplinary approaches learnt during lectures and workshops. The SUIP selected by one of the groups of YWPs was related to the flooding experienced by the residents of Chennai, India. Flooding is a very common phenomenon having its occurrence across the world with varying severity and magnitude because of changes to the use of river floodplains, changing the land use pattern, encroachment of waterbodies, and the impact of climate change on water resources. Chennai City in Tamil Nadu, India, with a population of about 6.5 million is facing frequent flooding because of extreme rainfall events and the presence of three rivers within the city and is also facing an acute shortage of water which also needs to be addressed for its sustainable development. This study used transdisciplinary approach to understand 2015 flooding in Chennai and made several recommendations to improve the flood management in Chennai including an early warning system. The YWP training and the concept of SUIP significantly enhanced the outcomes from this study.
