What is the news?
Meghalaya government has claimed that a detoxing project through the use of phycoremediation has rejuvenated Lukha river. The project was funded by the “District Mineral Fund”.
What is the reason for contamination?
The Lukha River was considered toxic beyond redemption a decade ago. Meghalaya’s pollution control board in its report blamed drainage from ‘acid mines’ drainage and ‘rat-hole coal mines’ as the reason for toxicity in the river.

The river passes into southern Assam’s Barak Valley and ends up in the floodplains of Bangladesh.
