Proposals Could Stem Pollution Leak At Former Llay Landfill Site

Plans to improve the capping at a former landfill site at Alyn Waters Country Park look set to be given the go ahead today.

There are currently high leachate levels leaking from the site which is causing contamination to 20 acres of land at the country park.

Under proposals being considered by Wrexham Council 6 months of work will be undertaken to prevent deficiencies within the clay cap, particularly around the perimeter of the site.

If successful the proposals would make extensive improvements to the capping of the closed Llay landfill, with associated pipelines and installation of monitoring equipment.

The aim is to reduce levels of leachate being produced on site and thus the risk the site poses to the environment through improvements to the perimeter cap with additional monitoring being held to determine whether further works are necessary.

The works would see 30 lorries going in and out of the site every day.

There are a number of nearby residential properties and one resident wrote to express their concerns regarding levels of noise, dust and vibrations stating: “we find ourselves again faced with years of similar problems.”

The report acknowledges that the works have the potential to cause noise and vibration from work associated with the reinstatement of the cap and from construction road traffic, but describes the impact as “unavoidable”.

The site was a former sand and gravel quarry which was worked during the early 1950s and was subsequently used for the controlled tipping of domestic, commercial and non-toxic refuse between 1988 and 1994.

Part of it is used for animal grazing and is managed by the HACK horse sanctuary

A previous survey found that there is the potential for a number of protected species to use the site, including badger, bats, reptiles and nesting birds.
