Delhi Farms Poisoned by Polluted Drain Water

Farming in Delhi's Dichaon Kalan, a significant cauliflower-producing area, is increasingly reliant on polluted drain water for irrigation. This practice has become widespread over the last 15 to 20 years, with farmers in areas like Jharoda Kalan using water from drains containing industrial effluents and sewage. Scientific studies by IIT-Delhi researchers have detected heavy metals such as chromium, copper, and lead in the drain water at concentrations up to 50 times the permissible limits.

The use of this untreated wastewater poses significant health risks, as identified by studies concluding that consumption of contaminated produce can lead to deleterious health effects. Experts note that the lack of proper irrigation channels, unlike in neighboring states, forces farmers to depend on these polluted sources when groundwater is not viable. Farmers are actively demanding alternative clean water solutions, such as canals, to ensure the safety of their produce and public health.

Incidents, like a drain breach in January that inundated fields with polluted water, highlight the precarious situation. Farmers recount how their produce grew in this toxic water, despite its foul smell and visible contamination. This reliance on contaminated water raises concerns about the long-term accumulation of heavy metals in soil and crops, impacting both agricultural sustainability and consumer safety.
