In the trans-boundary Ravi River flowing from India to Pakistan, in urban areas of Lahore the pollution levels in the river discharge are reportedly very high, which is attributed to careless disposal of large amount of industrial and agricultural waste water and faulty drainage systems in both countries. A stretch of the Ravi River from Lahore Siphon to Baloki headworks indicates heavy contamination of the water and sediment with Cd, Cr, Pt and Cu. The river sediments are highly contaminated and have become secondary source for pollution of the river water, even though some control over unauthorised discharges into the river have been checked. Hence, measures to check metal re-mobilization from sediments into the river flows needs attention. The worst affected drainage is the Hadharaam drain, a tributary of the Ravi River. It is also a trans-border problem involving both India and Pakistan. A UNDP funded a special programme was launched in 2006 to address the issue in both countries.
