Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what plans the Government has to remedy metal contamination of bed sediments in the Upper Mersey catchment that result from industry and urban development.

There are currently no plans in place to remediate existing metal contamination of bed sediments in the Upper Mersey Catchment. The Environment Agency (EA) does however have powers to limit pollution from heavy metals and uses these powers to prevent heavy metal pollution from entering the catchment.

In the wider water environment, Defra is working with the EA and the Coal Authority to tackle legacy impacts of industry through the Water and Abandoned Metal Mines (WAMM) programme. The WAMM programme targets pollution of the water environment in areas with a legacy of historical metal mining through the development and operation of mine water treatment schemes, which deliver benefits for the local environment, people and the economy. The current schemes successfully treat 7.4 billion litres of mine water each year and prevent 800 tonnes of metals from entering and polluting rivers.
