Long-term changes in wastewater reuse and health (India)

This research explored the historical relationship between wastewater reuse and health in villages surrounding the Jajmau sewage treatment plant in Kanpur, India. It focused on two villages in a life history case-control study: Alaulapur, a case village under a wastewater reuse scheme and Lalukheda, a control village under a groundwater reuse scheme. It employed in-depth life histories with 19 farmers aged above 55 years and 4 key informant interviews (KII) with experts. The study reviewed that farming practices and the community’s health status had evolved with irrigation water type. Alaulapur faces skin, lung, respiratory and cancerous conditions linked to potential long-term exposure to heavy metal contaminants like chromium, while Lalukheda experiences milder health problems. Alaulapur is limited to growing millet, rice, and wheat, which has potentially affected the nutritional diversity of the village’s diets and the overall health of its community members. In contrast, Lalukheda’s economic growth has improved primarily due to crop diversity and adequate food availability.Alaulapurs flooding irrigation method has led farmers to exposure to Escherichia coli (E. Coli) and chromium contaminants. It has contributed to methane (CH4) production, resulting in greenhouse gas (GHG) emissions in the environment. In contrast, Lalukheda has adopted modern irrigation practices.
