Tip restoration proceeds as expected, say engineers

INITIAL testing at the Auldcathie landfill site near Winchburgh show there are no significant amounts of gas seeping from the area.

Engineers Grontmij, who are in the process of restoring Auldcathie,l said this week early indications show gas generation at the centre of the site has peaked and is now decreasing.

Wells have been drilled to monitor the gas, soil samples are being analysed and ground water levels are being assessed at the site, which is part of the overall plan for the £1 billion Winchburgh makeover.

The wells have been placed at 250m intervals around the site to monitor any gas migration.

A Grontmij spokesman said: “We are measuring landfill gas indicators and the gas is not coming near the development zones.

‘‘There are no significant amounts of methane or CO2 being emitted and gas is not seeping out into Winchburgh.

“There is no gas migration issue and any gas is being managed through a venting system.”

Grontmij is working with the Scottish Environment Protection Agency and West Lothian Council to make sure every criteria is met when restoring the site.

The spokesman added: “The ground water is not good quality at the centre of the site but we are confident that this will be managed by the restoration project.

‘‘All waste is being documented - we have details about everything from bits of newspaper to an Irn Bru can from 2002. Investigations will be continued.”

Analysing the data should take around four weeks with a report being submitted to West Lothian Council in mid-October.

Grontmij representatives spoke at a meeting of Winchburgh Community Council on Monday evening.
