RIVER quality in the North West is continuing to improve, according to figures released by the Environment Agency (EA) today.

The Agency's annual survey of rivers and canals showed 91 per cent of the region's waterways were of good or fair chemical quality in 2002, compared with 75 per cent 10 years ago. Last year the Agency surveyed 7,000 sites representing 40,000km of rivers and canals for their chemical and biological quality across England and Wales. Among the rivers and canals that have sustained improvements in recent years is the Calder, near Whalley.

EA chairman, Sir John Harman, said: "We are starting to meet our threshold of improvement."
