SHILLONG, Aug 2: The once-pristine waters of the Rymben River in Lapalang village have turned murky and alkaline, causing alarm among the local community and researchers involved in a fish conservation project.
Villagers have reported that the river, a crucial habitat for the endangered chocolate mahseer (Neolissochilus hexagonolepis), has been increasingly polluted over the last three years, especially during the monsoon season.
Known for its serene and clean waters, the Rymben River became the focal point of a successful fish conservation zone established in 2021 by the village community and researchers.
The project aimed to safeguard and increase the population of the chocolate mahseer, a species under threat.
Initially, the initiative saw remarkable success, with a significant increase in the mahseer population.
However, this success is now under threat.
Villagers have reported that during the monsoon, the river’s water turns muddy and whitish, resembling cement water. This change has been attributed to wastewater from limestone mining activities near Pongtung village.
The debris flows into the river, raising its alkalinity, making it inhospitable for aquatic life in areas where the current is weak, and leading to the death of many fish.
The polluted water is also unsuitable for daily use, including washing, bathing, and even drinking in some villages.
Residents of Lapalang and surrounding villages have aired deep concern over the situation.
The community fears that if the pollution continues, it could devastate the mahseer population and endanger the livelihoods of those who depend on the river.
