Contractor Hydrock is close to completing a remediation works programme that will help a £400m science and innovation campus to go ahead in Swansea.
The new Swansea University campus on a site off Fabian Way, east of Swansea Docks, will receive £15m in funding from the Welsh Assembly and outline planning permission has already been granted.
Hydrock began a remediation works programme at the 69-acre site, owned by St Modwen Properties, last summer working alongside consultants Atkins.
The firm’s work has included remediation treatment of hydrocarbon impacted soils and groundwater, a legacy from the former owners operations on the site.
Project director Mike Higgins said: “It has been a challenging project from the start, due to the timescales, the contamination present and the proximity of Swansea Bay, made easier by the team-oriented approach of St Modwen and their advisers, and the thorough understanding of the site conditions gained by Atkins prior to our involvement.
The remediation work is being undertaken in full consultation with Environment Agency Wales and Neath Port Talbot Council.
An economic study by the University estimates the project will contribute more than £3 billion to the regional economy over the next 10 years and create thousands of jobs.
