JODHPUR, April 23 -- Traditional water harvesting systems in Jodhpur harbour high levels of pollution, including microplastics and heavy metals, threatening their role as vital resources in the arid region, a new Indian Institute of Technology (IIT) Jodhpur study has found. The research examined 12 structures: Toolji Ka Jhalra, Mahila Bag School Ka Jhalra, Mahila Bag Ka Jhalra, Achalnath Mahadev Mandir, Chand Bawri, Gulaab Sagar, Fateh Sagar, Jeta Bera, Silota Ke Masjid, Teliyo Ke Masjid, Padma Sagar, Govinda Baori, and Kaylana Lake. "Urban water management has emerged as a critical barrier to sustainable development, threatening public health, economic stability, and ecosystem integrity due to recurrent floods or water scarcity. Traditional Water Harvesting Systems (TWHS), once reliable sources of water in arid regions, are increasingly compromised by stagnation, pollutant inflows, and neglect," said Chandana N, assistant professor, department of environment and sustainability engineering (DESE) and affiliate faculty at civil and infrastructure engineering, IIT Jodhpur. She added, "This study assesses the current condition and restoration potential of TWHS in Jodhpur. Twelve TWHS were monitored over a cycle consisting of pre-monsoon, monsoon, and post-monsoon seasons to evaluate water quality, microplastic (MP) contamination, and trace metal loads. Household surveys and focus group discussions provided insight into user perceptions and management practices." Results showed severe water quality....
