Aquifer-Specific Groundwater Temperature Map of Missouri, Springfield Plateau Aquifer and Equivalent Bedrock Units (2013) OFM-13-639-GS

Basic Information
Author: Tracey Mason
Description:This map illustrates the measured groundwater temperatures and depths in the Springfield Plateau Aquifer and equivalent bedrock units throughout the state of Missouri. The aquifer comprises the upper Mississippian Subsystem, from the Ste. Genevieve Limestone to the Osagean Series (undifferentiated). Each well data point has a corresponding groundwater temperature and depth measurement. These depth measurements were used to verify that the well water was originating from the Springfield Plateau Aquifer and equivalent bedrock units. Groundwater temperature data was collected state-wide from public water supply districts and springs. These measurements were taken with a YSI conductivity meter that measures temperature. This data includes measurements from oil and gas geophysical logs, Plains CO2 Reduction (PCOR) partnership data, Shallow Carbon Sequestration Demonstration Project, and springs data gathered from Missouri Department of Natural Resources publications and files. Additional data was collected from U.S. Geological Survey publications. Temperature data accuracy reflects original data source. The contours were generated in ArcView TM10.0 using raster interpolation, within the 3D Analyst Tools. The raster interpolation utilized the natural neighbor tool. Subsequent to generating the raster image, the raster surface tool was used to contour the data from the raster interpolation. Some manual editing was performed to ensure contour lines honor data points values and guarantee data quality. The units of the contours are in degrees Fahrenheit and depict the temperature-at-depth for the aquifer. This data shows that the geothermal characteristics of Missouri support use of ground source heat pumps (GSHPs) that generally do not need to be drilled deeper than 1,000 feet. The use of geothermal GSHPs has the potential to reduce the reliance on fossil fuels for heating, ventilation, and cooling (HVAC) consumption. These systems are excellent economical alternatives to electric and fossil fuel powered HVAC systems. This map was provided by the Missouri Department of Natural Resources, Division of Geology and Land Survey and made available for publication through the National Geothermal Data System.
