Newbury Gasworks site, within the Sterling Industrial Estate, has had a long history of industrial use leaving a heavily contaminated site within a built up area of Newbury surrounded by residential and commercial properties. Stringent environmental monitoring was therefore required to ensure minimal impact on the local environment. A main line railway line on the southern boundary of the site meant works had to be carried out under strict asset protection agreement with Network Rail. Demolition was also required of a redundant building adjoining an operational office/workshop commercial industrial past meant that remediation was essential and several approaches were required to decontaminate the site to meet regulatory approval.
Cognition was appointed by Nelson Land and PSP Consulting to remediate the site to reduce environmental and human health risk and enable redevelopment to Residential Apartments with Basements. The key elements of these works included:
Cognition successfully remediated 17,000m3 of contaminated materials on site to meet remedial criteria for residential use. This included the removal of NAPL to <5mm thickness on groundwater interface by deploying the fabric extraction system . A protective PRB wall around the site will protect against potential off-site contamination migration. The works were carried out with minimal disruption to local residents.
One of the key successes was the liaison with the residents and regulators from inception through to completion. Cognition endorsed regular visits from both the Local Authority and Environment Agency throughout the works. Regular newsletters issued to the local community provided details of anticipated site works and progress. This was commended by regulators given that the site was overlooked by many properties. The scheme had been many years in planning and the successful remediation has formed an outstanding first stage in this highly-publicised development.
