Abstract

Aquifer systems in the Dickinson lignite area of North Dakota are in sandstone beds in the Fox Hills Sandstone and lower Hell Creek Formation, in the upper Hell Creek Formation and lower Ludlow Member of the Fort Union Formation, in the upper Ludlow and lower Tongue River Members of the Fort Union Formation, and in the upper Tongue River and the Sentinel Butte Members of the Fort Union Formation. Well yields from each of the aquifer systems generally are less than 100 gallons per minute. Water in the Fox Hills-lower Hell Creek aquifer system and in the upper Hell Creek-lower Ludlow aquifer system is soft and a sodium bicarbonate type. Dissolved-solids concentrations range from 1 ,010 to 1,690 milligrams per liter. Water in the upper Ludlow-lower Tongue River aquifer system and in the upper Tongue River-Sentinel Butte aquifer system ranges from soft to very hard and generally is a sodium bicarbonate type. Dissolved-solids concentrations range from 574 to 2,720 milligrams per liter. Discharges of ground water are less than 0.1 cubic foot per second to the Cannonball River and less than 1.0 cubic foot per second to the Heart River. (USGS)
