Shillong: Shillong's primary rivers, the Umshyrpi and the Umkhrah, remain severely polluted despite years of environmental campaigns and government restoration promises. Recent water quality assessments from the Meghalaya State Pollution Control Board for May 2026 classify these waterways as having unsatisfactory water quality across all monitored locations.
Technical data confirms the extent of the ecological crisis. At the Umshyrpi Bridge, biological oxygen demand levels reached 17 mg/l, which is nearly six times higher than the standard limit. Near the local Law College, the situation is more dire, as dissolved oxygen levels were recorded at zero and faecal coliform concentrations hit 93,000 MPN per 100 ml. Similar conditions exist along the Umkhrah, where sites near Demthring and Mawlai also recorded a complete absence of dissolved oxygen.
The pollution is largely driven by the direct discharge of untreated sewage, exacerbated by rapid urban growth and gaps in the city's sanitation infrastructure. While successive governments have announced various rejuvenation projects, environmental observers suggest that implementation remains the primary hurdle. Official reports indicate that the city's rivers continue to fail, stating that "the Umshyrpi and Umkhrah serve as a reminder that environmental protection is ultimately judged not by the number of saplings planted or speeches delivered, but by the condition of the ecosystems governments and citizens claim they are working to protect."
Institutional shortcomings are only part of the issue. Authorities point to continued public negligence, including the illegal dumping of garbage and waste encroachment along riverbanks. Experts maintain that while awareness campaigns are useful, they cannot replace the urgent need for proper sewage treatment facilities, strict enforcement against polluters, and comprehensive waste management systems.
