Geofirma worked with South Nation Conservation Authority to develop an Aquifer Capability Screening Tool (ACST) for the City of Clarence-Rockland to help pre-screen potential water quality and water quality concerns for water supply of privately-serviced lots. The ACST pre-screens development applications and provide information to the applicant regarding potential water quantity or water quality at the proposed site prior to initiating a study and it is anticipated that this advanced notice of water quantity and water quality will save the applicant and municipality time and money during the overall development application process. The ACST is a GIS-based tool created from a series of maps that outline areas of potentially limited water quantity and areas with potentially lower water quality. The maps were generated through the interpretation of geology (surficial and bedrock), groundwater pumping data and groundwater quality data and extrapolate the data across the City of Clarence-Rockland. The results of the study highlight the importance of comprehensive water quality analyses when characterizing drinking water supplies.
