AbstractGroundwater flow does not stop at municipal, provincial, state, or national boundaries, but groundwater data typically does. This makes the data difficult to find and use, particularly for cross-border studies, because it is distributed amongst many agencies, in different formats, using a variety of methods. This situation is not unique to groundwater data, but is typical of water data in general. Emerging international solutions include the development of water data networks that link together distributed online sources using open geospatial data standards. The Canadian Groundwater Information Network (GIN, and the U.S. National Ground Water Monitoring Network (NGWMN, data portal/) are examples of such networks. They address the data accessibility issue by providing single points of online access to a distributed collection of groundwater data. As a result, users are able to view, query, and download the data transparently, as if it resided in a single repository. GIN's base layer of data consists of water well databases from eight provincial agencies, but recent work has added historical water level time-series from three provincial monitoring networks and one local conservation authority. The use of open standards for both accessing and formatting the data ensures the GIN approach is compatible with the NGWMN prototype, which includes monitoring networks from five states and the USGS. This submission will recap the common GIN and NGWMN approach, discuss the underlying technical advances, and present results of an experiment that confirms their interoperability. Overall, these results signal the nascent emergence of a North American network for online groundwater data.
