DRASTIC Results 2019

The DRASTIC model was developed by the US EPA as a way of quantifying an aquifer’s susceptibility to surface contamination events. In 1997, the NDDoH Environmental Health Section, now the Department of Environmental Quality, applied this system to North Dakota’s shallow aquifers as part of the North Dakota Geographic Targeting System for Groundwater Monitoring (GTS). In 2015, it was decided to update the GTS to reflect changes in aquifer boundaries, water use and land use. The complete report was finalized in October 2019 and is available online here. (URL https://deq.nd.gov/publications/wq/1_GW/GeoTargetSys/2018_GTS/2019_GTS_R...). The DRASTIC model was reapplied to all known shallow groundwater resources within North Dakota in order to obtain the Vulnerability rating shown in the Attachment on page 32 of the report.
