|Biggest Hurdle:||The post-fire remediation process was very challenging because it was done during the winter months, and the contaminated water had to be thawed before it could be treated and disposed of.|
XCG was retained to conduct the studies necessary to file Records of Site Condition (RSCs) with the Ontario Ministry of the Environment and Climate Change (MOECC) for a brownfield property in Kingston, Ontario, to allow for a change to residential land use. The property was being redeveloped as a 140-unit student apartment complex.
XCG completed Phase One and Two Environmental Site Assessments (ESAs) of the property. This involved full delineation of soil and groundwater quality impacts. The soil contamination identified on the site included metals, petroleum hydrocarbons (PHCs), and polycyclic aromatic hydrocarbons (PAHs). The groundwater contamination on site included mercury, several volatile organic compounds (VOCs), and PHCs (F2 and F3). The groundwater contamination was isolated to a small portion of the site. Thus, remediation of the soil and groundwater was required in order to file RSCs.
XCG conducted a clean-up of environmental impacts at the site, starting with soil remediation. Approximately 11,000 metric tonnes of contaminated soil was excavated and hauled off-site. Following the soil remediation, a RSC was filed for the portion of the site that did not have groundwater contamination. On the remaining parcel where groundwater contamination had been identified, six months of follow-up groundwater testing was completed after the soil remediation. Following confirmation of the successful remediation of the soil and groundwater on the remaining parcel, a second RSC was filed, completing the RSC process for the entire site.
Following the successful completion of this project, a fire destroyed the partially constructed building on the property. The fire made international headlines when a military helicopter dramatically rescued a crane operator trapped high above the ground by the flames. Following the fire, XCG completed a clean-up to treat and remove the contaminated fire water from the below grade parking garage. This remediation process was very challenging because it was done during the winter months, and the contaminated water had to be thawed before it could be treated and disposed of. XCG completed the remediation successfully in a period of approximately nine weeks.
