In the US state of California, a small property developer is
benefiting from the environmental remediation of its property
portfolio, which includes 15 shopping centres. Seven of these
contained dry cleaning facilities and had documented releases of
chlorinated solvents, which were historically used as part of the
dry cleaning process.
Seeking to improve environmental and compliance outcomes, the
developer engaged GHD to perform investigations of the dry cleaning
facilities, commission remediation activities, and work closely
with regulatory agencies overseeing the projects. Mark Dockum,
GHD's Job Manager says, “We performed soil remediation (soil
excavation activities) at two of the sites and successfully
negotiated closure of these sites with the regulatory agencies.
Various remediation technologies including Soil Vapour
Extraction (SVE) and Air Sparge (AS) for soil as well as in-situ
Enhanced Reductive Dechlorination (ERD) for groundwater are
currently being completed at several of the other sites.
"The remedial methods used in this project, in particular SVE,
AS and ERD, are excellent technologies that allow for remediation
of the various media without the removal of soil and/or
groundwater, and are at the forefront of industry practices."
Over the course of the project, GHD was commended by the
regulatory agencies for the quality of its work, and ability to
provide excellent technical interpretation of the data and clear
communication of schedules/ progress at each of the sites. This
seamless delivery has meant that the investigation and remediation
activities have proceeded at a much faster pace than most
Once the projects are completed, the developer will have boosted
the value and versatility of its property portfolio and will hold
environmentally unencumbered properties allowing for unrestricted
