REGENESIS have recently been involved in a remedial pilot study for a former gas works site in the South East, as part of its proposed high density development scheme. The site is situated within a high risk area for groundwater vulnerability with an aquitard protecting the underlying principal aquifer. A reduction in DNAPL and groundwater LNAPL concentrations are required to allow deep piling to take place.

A remedial solution was required that would address the groundwater contamination in the bedrock and sorbed contamination in the soils.
