WSP, as part of a GHD-led team, contributed to the design plan to dredge, decontaminate and store the sediment and for developing the infrastructure to do so. WSP also led efforts to refine the estimates of contaminated material using innovative in-situ sludge thickness measurements. In addition, close to 6 million cubic metres of water will have to be treated during the remediation process. The planning will also have to factor in future sea level changes and storm surges once the harbour is reopened to the Northumberland Strait.
WSP's team, which included collaboration with members of Pictou Landing First Nations, has expertise in the areas of environmental protection, geomatics, infrastructure and structural/geotechnical engineering. The full clean-up is scheduled to start in 2022. Thanks to its multidisciplinary contributions, WSP will be collectively helping to right a historic wrong.
