Ceredigion C.C. wished to redevelop a former coal carbonisation gasworks to create school playing fields as part of a PFI project. We initially undertook a comprehensive desk study and subsequently designed a site investigation to enable a quantified risk assessment to be completed.

Geophysics were used to establish the locations of buried structures and trial pits/boreholes provided soil and water samples. The quantified risk assessment allowed an outline remediation strategy to be developed.

Following this project, ExCAL were again commissioned by Ceredigion C.C. to provide environmental impact assessments for improvements on the A485 and various points along the A486; these were at Horeb Crossroads, Croeslan, Ffostrasol and Capel Cynon. Detailed ecological surveys were undertaken to supplement the EIAs.

ExCAL were commissioned by Ceredigion C.C. to provide a detailed quantified risk assessment for three former lead mines in mid Wales. Historical studies, an archaeological study and ecological studies were undertaken in order to allow site investigations to be designed.

Protected lichen species were present on some of the sites, and the sites all lay adjacent to rivers. A cost benefit analysis was undertaken to identify the effects that could be anticipated on fauna for various remediation strategies.

We have also carried out detailed asbestos surveys on a series of schools and other public buildings within Ceredigion.
