Remediation of orphaned sites inundated with wood preservatives (pentachlorophenol & creosote), and detailed environmental impact assessment of dichloro-octyl-isothiazolinone (DCOI) on soil core and groundwater

There is a pressing need for studies centered on the impact assessment of emerging wood preservatives and the remediation of orphaned sites. The present proposal describes a dual-purpose research project. The project aims to; (i) apply a modified in situ chemical oxidation technique for the removal of pentachlorophenol (Penta) and creosote compounds in orphaned sites and; (ii) conduct a comprehensive environmental impact assessment of the dichloro-octyl-isothiazolinone (DCOI)-formulated wood preservative on soil cores and groundwater. Penta and creosote can be referred to as legacy pollutants. They used to be the foremost wood preservatives until their restrictions due to the toxicity potential they pose to humans and aquatic organisms. Conversely, DCOI is one of the present-day’s choices approved for use as a wood preservative in the United States. Findings from this project may provide some basis for DCOI’s approval for use in Canada; and this will be advantageous to Stella-Jones Inc.
