SHILLONG, June 7: Shillong’s rivers are failing the ultimate test of the state’s environmental commitment. While World Environment Day 2026 unfolds with plantation drives and glossy conservation promises, fresh data from the Meghalaya State Pollution Control Board (MSPCB) delivers a troubling verdict: the city’s major rivers—Umshyrpi and Umkhrah—remain severely polluted, with no meaningful signs that years of campaigns, projects, and political pledges have reversed their ecological decline.
The latest water quality assessment for May 2026 paints a grim picture of the Umshyrpi and Umkhrah rivers, both of which continue to be classified as having “Not Satisfactory” water quality at all monitored locations.
At Umshyrpi Bridge, dissolved oxygen (DO) levels stood at 4.2 mg/l, below the desirable level of above 5 mg/l required to sustain healthy aquatic ecosystems. Biological Oxygen Demand (BOD), a key indicator of organic pollution, was recorded at 17 mg/l, nearly six times higher than the prescribed standard of less than 3 mg/l.
The situation is even more alarming near Law College, where dissolved oxygen was recorded as nil, indicating water conditions incapable of supporting most aquatic life. The BOD level touched 53 mg/l, while faecal coliform concentration reached 93,000 MPN per 100 ml against the acceptable limit of 2,500 MPN per 100 ml.
The Umkhrah river fares little better. At Demthring, dissolved oxygen was absent and BOD stood at 35 mg/l. Near the slaughterhouse area, BOD climbed to 48 mg/l while faecal coliform levels reached 84,000 MPN per 100 ml. At Mawpdang, Mawlai, dissolved oxygen was once again recorded as nil.
Taken together, the figures point to rivers under severe ecological stress and heavily contaminated by organic waste and sewage.
The data also raises a larger question: why do Shillong’s rivers continue to deteriorate despite repeated environmental campaigns and government interventions?
The answer appears to lie in a combination of rapid urban growth, inadequate infrastructure and continued public negligence.
Shillong’s population has expanded significantly over the years, increasing pressure on drainage systems, sanitation infrastructure and waste management facilities. More households, commercial establishments and settlements inevitably generate larger volumes of wastewater and solid waste.
However, population growth alone cannot account for the extent of pollution reflected in the latest figures.
The exceptionally high faecal coliform levels strongly suggest the continued discharge of untreated sewage into the rivers. Large stretches of the city still lack comprehensive sewerage connectivity, while wastewater from households and commercial establishments often finds its way into streams and drains that ultimately flow into the Umshyrpi and Umkhrah.
Environmental observers note that the problem has been identified for years. Successive governments have announced river rejuvenation initiatives, sanitation projects, solid waste management measures and beautification programmes. Yet the water quality indicators show little meaningful improvement.
This points to a gap not necessarily in awareness, but in implementation.
At the same time, responsibility does not rest solely with the authorities. Illegal dumping of garbage, disposal of waste into drains, encroachment along riverbanks and poor waste management practices by residents continue to contribute to the degradation of urban water bodies.
The condition of the rivers suggests that Shillong’s pollution crisis is the result of both institutional shortcomings and public behaviour.
The irony is difficult to miss. While environmental awareness has arguably never been higher and plantation drives continue to receive significant attention, the city’s most visible natural waterways remain among the clearest indicators of an environmental challenge that has yet to be effectively addressed.
For many environmentalists, the lesson is straightforward. Tree plantations and awareness campaigns are important, but they cannot substitute for sewage treatment facilities, effective waste management systems, strict enforcement against polluters and sustained restoration efforts.
As another World Environment Day passes, 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.
