HC Deb 13 March 1986 vol 93 c556W
Mr. Chris Smith

asked the Secretary of State for the Environment what are the concentrations and quantities of (a) tributyltin and (b) dieldrin released into the River Rother during pollution incidents in 1985; and if he will state the source of the pollution.

Mrs. Rumbold

In October 1985 there was a leakage of tributyltin and dieldrin from a timber treatment tank into the Newmill Channel, a tributary of the River Rother. Prompt action by the Southern water authority contained the spillage, and none entered the River Rother until it had been diluted very considerably. No adverse effect was observed in the River Rother.
