GTS Surficial Aquifers

The goal of the North Dakota Geographic Targeting System for Groundwater Monitoring (GTS) was to reassess monitoring priorities for existing glacial drift aquifers, assign monitoring priorities to new aquifers, and update the methods of the GTS to include new geographic information system (GIS) capabilities. The GTS is a tool used by the Agicultural Ambient Groundwater Monitoring Program to assign monitoring priority to shallow aquifers. This layer represents maps in Attachment 3 of the "North Dakota Geographic Targeting System For Groundwater Monitoring" dated October 2019. The report is published by the North Dakota Department of Environmental Quality, Division of Water Quality. Full report available online at
