Client: Associated Engineering/Halton Region
Location: Trafalgar Road, Georgetown, ON
Budget: $78, 000

XCG was sub-contracted by Associated Engineering to conduct a Phase One Environmental Site Assessment (ESA) and Phase Two ESA as part of the Zone 4 Reservoir Design and Construction project for Halton Region. Halton Region purchased a rural property for the purpose of constructing a new drinking water reservoir and as part of the overall project required a Phase One ESA be completed prior to development of the property.

In the fall of 2015, XCG completed a Phase One ESA in accordance with Ontario Regulation 153/04, as amended (O. Reg. 153/04) and CSA Standard Z68-01(R2006). The Phase One ESA included review of available background records including aerial photographs, insurance inspection reports, and regulatory database records including spill reports. Based on the findings of the Phase One ESA, one Area of Potential Environmental Concern (APEC) was identified. Halton Region requested that a Phase Two ESA be completed to investigate this APEC.

In the spring of 2016, XCG completed a Phase Two ESA to investigate the identified APEC identified.  This APEC was investigated through the advancement of a total of five boreholes, three of which were instrumented as monitoring wells.  The Phase Two ESA included logging of boreholes, collection of soil and groundwater samples, surveying of monitoring well elevations, measurement of depth to groundwater and determination of equipotential contours, laboratory testing /chemical analysis of potential contaminants of concern, and  preparing cross section figures illustrating the geology of the site.  Following the initial sampling, the three existing wells were re-sampled as well as four additional wells installed on-site (originally for geotechnical purposes).  XCG prepared a detailed report summarizing the findings.

Through communication with all parties and detailed project management, XCG was successful in providing the required environmental information to the satisfaction of Halton Region, the client (Associated Engineering), and in accordance with Ontario Regulation (O. Reg.) 153/04, as amended, and the Region was able to proceed with the development project.
