|Abstract||Ontario's Ministry of the Environment and Climate Change (ministry) has a dataset of over 750,000 well records from 1899 to present with a growth rate of 15,000 to 20,000 records per year. Well records
provide information about a well's location, construction, lithology and pumping test, as prescribed by the Wells Regulation. In general, a well record is required to be submitted by the well contractor at the time of construction, major alteration
or decommissioning of water supply wells, test holes and dewatering wells.|
Since its inception, the provincial well record dataset has been an invaluable resource for geologists, engineers, and other stakeholders across the province as it is the
primary source of province wide subsurface geological and groundwater information. It is made available through the ontario.ca website as a Data Catalogue and an Interactive Well Records Map.
Data on the well records are of varied quality with
some well records providing a high degree of accuracy and completeness, and others not. During use of the well record data by external stakeholders, professional geoscientists and engineers have assessed and corrected the data, and added new data to
produce "value-added" well record datasets for their areas of study. They have checked for and interpreted for regional consistency in nomenclature, location, etc.
In November 2016, the ministry initiated the Well Record Enhancement Project to
determine how to create, maintain and present an authoritative provincial well record dataset in which the geoscience community has confidence and can contribute ongoing improvements. WSP Canada Inc. was retained to assist with the delivery of this
The objectives of the project are to identify and assess options to 1) enhance the quality of Ontario's well record data, including the integration of existing value-added datasets; 2) identify how to validate/curate corrections and value
added data from external sources into a "best available" dataset on an ongoing basis; 3) enhance how well record and value-added data are made available to the public, including improved functionality/presentation and delivery models; and 4)
potentially recover the costs of enhancements and delivery. Recommendations are to be based on a solid understanding of the needs and capacity of the MOECC, other existing well record users and creators of existing value added datasets including
professional geoscientists, engineers and well contractors.
To this end, the ministry is consulting with key stakeholders to better understand what enhancements they need and want in terms of well record quality, access, presentation and delivery.
In addition the ministry is examining what corrected/value added data may be available for a curated authoritative provincial dataset, and what role, if any, stakeholders would like to play in its delivery.
