Several of the conservation authorities (CA) in eastern Ontario are partnered with the City of Ottawa to provide technical advice about hydrogeological studies that are submitted to the City in support of development applications and about related policy and guidance development. These CA's also facilitate Source Protection initiatives for the local Source Protection Regions and maintain an ongoing partnership with the Ministry of the Environment and Climate Change (MOECC) to collect data from local Provincial Groundwater Monitoring Network (PGMN) wells. In addition, the City also owns information from municipal wells and data from numerous land use monitoring programs. As a result of the above responsibilities, the CAs and City house a tremendous amount of hydrogeological information in separate paper, pdf, tabular, and various old database formats; all of which has never been catalogued. Moreover, this data cannot currently be accessed, summarized, mapped or analysed together. However, there are on-going demands for the presentation and use of this information during the course of regular municipal and conservation authority business. To address the above hydrogeological data management gap, in 2016, the City of Ottawa in partnership with the Rideau Valley Conservation Authority implemented a project to develop a hydrogeological geodatabase and data harvesting plan. This presentation will provide an overview of the project context, outcomes and anticipated next-steps.
