A collaborative approach: Creating robust remediation designs to accommodate site realities

Language: English
Presenter: Steve Jackson (Soilfix), Jack Shore (REGENESIS)

In this webinar, Steve Jackson from Soilfix and Jack Shore from Regenesis discuss why a collaborative approach between consultants, contractors and technology vendors is critical when dealing with complex sites. Using a recent project as a case study, they delve into the planned remedial approach and explaine how the site challenges were overcome. They also discuss how to best design for sites where the groundwater remediation objective is ‘Betterment’.

About the project: this is a complex site where a historic timber yard was demolished and an office facility built in its place in the early 1980s. The site was found to be impacted with high levels of petroleum hydrocarbons as well as a mixture of pentachlorophenol, trimethyl tin and pesticides (lindane, dieldrin and aldrin, amongst others), which was thought to be a result of the timber yards industrial practices. Due to divestment; the owner of the office park wished to remediate the site before the sale.

An integrated remediation strategy was devised to accelerate closeout. This strategy comprised excavation, ISCO, In situ sorption and enhanced biological degradation, to achieve low groundwater concentrations. Once onsite, it was discovered that conditions differed from that identified in the site investigation, threatening the ability to apply the necessary in-situ substrates.

This presentation explains the planned remedial approach, the challenges overcome and the importance of collaboration when dealing with a complex site.
