Description

The North Dakota Geographic Targeting System for Groundwater Monitoring (GTS) was first conducted in 1997 as a method of assigning monitoring priority to shallow aquifers. The decision to update the monitoring priority was made in 2015 in response to changing aquifer boundaries, land use, and groundwater appropriation. The analysis was complete and published in 2018. Additional update to address water levels in confined aquifers was completed December 2018 and published in October 2019.

The GTS consists of three components: Vulnerability, Sensitivity, and Risk. Each component is given three values: a Value, a Score, and a Rating. The Value is the numeric representation of each component. The Score is a number ranging from 1 to 3, and is assigned based on the Value range. A Rating can be LOW, MODERATE, or HIGH, and correlates to a Score rating of 1, 2, or 3 respectively.

The score of each component is added together to achieve a total monitoring score ranging from 3 - 9. The Total Monitoring Rating is then assigned based on this score: 3-4 (LOW), 5-7 (MODERATE), 8-9 (HIGH).

This dataset has value, score, and rating fields for each component, total monitoring score, total monitoring rating, and DRASTIC and Pesticide DRASTIC value fields.

COMPONENT RATINGS

Vulnerability

Pesticide DRASTIC Value - Score - Rating

0-130 - 1 - LOW

131-160 - 2 - MODERATE

160+ - 3 - HIGH

Sensitivity

Production (in dollars per farmed acre) Value - Score - Rating

0-202.14 - 1 - LOW

202.15 - 356.91 - 2 - MODERATE

356.92+ - 3 - HIGH

Risk

Appropriated acre-feet per square mile - Score - Rating

0-1.243 - 1 - LOW

1.244-33.50 - 2 - MODERATE

33.21+ - 3 - HIGH

Total Monitoring Score

Vulnerability Score + Sensitivity Score + Risk Score = Monitoring Score (Monitoring Rating)

3-4 (LOW)

5-7 (MODERATE)

8-9 (HIGH)

Dataset Finalized: October 2019


Summary

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.
