Water Availability in the Big Sioux Aquifer

Submitted by Anonymous (not verified) on

The city of Sioux Falls, South Dakota, requires a sustainable supply of municipal water to meet current demand and support future economic development and population growth. As such, the city has requested USGS assistance to provide information that will be useful in evaluating and managing its groundwater resources. The project will rely on an airborne electromagnetic survey (AEM) of the Big Sioux aquifer to help define the aquifer subsurface characteristics. These data will then be used to develop a groundwater flow model of the Big Sioux aquifer for management decision making. The study was initiated in 2015 and will conclude in 2018.
