Engineering and management consultancy Design2e has said that work on a new phase of groundworks to decommission a chemical works in the north east has got underway.
The firm has said that the current work at the Elementis Chromium site in Stockton on Tees follows on from work it has been involved in since 2012.
The contamination issue at the site, which closed in 2009 but is still owned by Elementis Chromium, centres around chemical cells containing chromium that were buried 20m below ground level.
Design2e’s contract includes the production of detailed earthworks, cell cap design and specification, drainage and overland flow modelling, geotechnical testing, the production of a construction quality plan and overall validation.
“This is now our fourth tranche of work at this site,” said Design2e executive director Wayne Holt. “Working within legislative specification guidance, we have worked to strengthen the clay walls, as well as strengthening and improving the surface layer.
“We have also modelled the profile of the area to ensure that rain runs off and is managed effectively.
“This will be an ongoing process to ensure the residue disposal facility is maintained and managed effectively for years to come.”
