This project exemplifies a highly sustainable form of remediation, virtually devoid of environmental burden with low H&S risks, and with estimated cost savings likely to have exceeded £500,000. The outcome was the best the client could have hoped for and exceeded project sign-off goals proposed to the regulators.
“ This highly technical groundwater remediation project impressed the judges. It demonstrated a range of techniques that were used to gather high quality data to monitor the progress and the success of the project.”
“This project was an excellent example of how existing technology can be thoughtfully applied.”
“Great teamwork by Hyder and REGENESIS Europe has provided the best hoped for outcome, with minimal disruption to our operation and neighbourhood.”
Tetrachloroethene (PCE) is used as a dry cleaning fluid at an industrial dry cleaning facility near Manchester, in the Northwest of England. In the early 1980s, prior to Johnsons Apparelmaster ownership, a delivery spill occurred. Most of the spill was captured by hardcover and within surface drainage but up to 2 tonnes was estimated to have entered the made ground and clay soils beneath the yard and factory, to depths of 10m BGL. As part of Johnsons’ CSR policy and liability provision, they investigated the historic spill and determined that remediation was required to protect off-site receptors and remove the potential for action under Part 2A. The project was initially managed by another consultancy, who had proposed pollutant mass reduction via excavation. Hyder were asked to provide a peer review and were then retained to help deliver an alternative, less disruptive and more and cost-effective in situ remediation. They researched whether the degree of pollution present (several zones of DNAPL) and high impact to groundwater could be addressed by enhancement alone and concluded it would be possible to reduce risk to acceptable levels by using REGENESIS products.
