Speakers: Helena Nord (RGS Nordic) and Jack Shore (REGENESIS)

Our webinar guest speaker series continues with Helena Nord of RGS Nordic discussing a complex groundwater project located in a redevelopment area in Central Stockholm, Sweden. A former gasworks left a complex mix of contaminants impacting the soil, groundwater and shoreline sediments. One of the more challenging problems to overcome was the contaminated groundwater at depth: down to 20 meters below ground level. The City of Stockholm engaged RGS Nordic who worked with REGENESIS to find viable solutions to the problems. In this webinar you will learn how three sets of pilot tests were carried out using different in-situ remediation products – including PersulfOx®, RegenOx®, ORC Advanced® and PetroCleanze® – to test the efficacy of in-situ chemical oxidation (ISCO), enhanced aerobic biodegradation (ENA) and enhanced desorption, and how the outcome of these have informed the full-scale remediation design of this complex site.
