Four Decades After Bhopal, Residents Still Fear the Water They Drink

Fresh water tests conducted by activists have raised concerns over sewage contamination in several neighbourhoods around the former Union Carbide plant, reviving questions about public health and infrastructure in one of India’s most enduring industrial disaster zones.

More than four decades after the Bhopal gas tragedy, many families living around the abandoned Union Carbide factory continue to grapple with concerns that extend far beyond the toxic gas leak that changed their lives in 1984. For many residents, the daily question is no longer only about the air they once breathed but also about the water that now flows from their taps.

A coalition of survivor organisations has claimed that 68% of drinking water samples collected from affected neighbourhoods showed signs of sewage contamination. According to the groups, 63 water samples were collected from 30 localities between July 2 and July 22, with 43 samples testing positive for the presence of faecal coliform bacteria, an indicator of possible sewage contamination.

The findings have renewed concerns about ageing civic infrastructure and the quality of drinking water supplied to communities that have long demanded better healthcare, rehabilitation, and environmental protection. Activists argue that access to safe drinking water remains a fundamental challenge for thousands of families living near the disaster site.

The groups also warned that the situation bears similarities to recent incidents of contaminated municipal water supplies that resulted in serious public health consequences elsewhere in Madhya Pradesh. They have called for immediate testing by government agencies, replacement of damaged pipelines where necessary, and regular public disclosure of water quality data.

According to the activists, contamination was detected across several neighbourhoods, including some where water pipelines had been laid only in recent years. Samples collected from different water sources reportedly showed varying levels of contamination, raising further questions about the integrity of sections of the city’s water distribution network.

The water testing exercise was undertaken after months of representations to civic authorities seeking official intervention. Survivor organisations say the initiative was intended to document conditions on the ground and draw attention to what they describe as an urgent public health concern requiring independent verification and corrective action.

The Bhopal gas tragedy remains one of the world’s worst industrial disasters, and many affected families continue to face long-term health, environmental, and social challenges. For residents living in its shadow, concerns over clean drinking water have become another chapter in a decades-long struggle for rehabilitation and basic public services.

Authorities have yet to publicly respond in detail to the findings presented by the activists. Independent verification by government agencies would be necessary to confirm the reported contamination levels and determine the appropriate remedial measures.
