Summary

This data release presents tabular data and water-level drawdown model files for 32 Mississippi River Valley alluvial aquifer monitoring wells and 4 Memphis aquifer observation wells from an aquifer test conducted in October 2017 at the Tennessee Valley Authority Allen power plants in Memphis, Shelby County, Tennessee. The dataset contains the water-level model files used to estimate drawdown in the monitoring and observation wells during the aquifer test, created using the SeriesSEE Excel add-in program (Halford and others, 2012). The SeriesSEE Excel add-in also is included so that water-level models can be reactivated.

Purpose

A short-term, stepped aquifer test of four Memphis aquifer production wells installed at the Tennessee Valley Authority Allen Combined Cycle Plant was conducted in October 2017 to determine the extent of drawdown in water levels in the Memphis aquifer and the potential for hydraulic connection between the Memphis aquifer and the overlying Mississippi River Valley alluvial aquifer, locally. Drawdown in distant observation wells or observation wells completed in a different aquifer is often masked by natural or environmental water-level fluctuations. The application of analytical water-level models such as SeriesSEE to aquifer-test data provide a mechanism to distinguish pumping and non-pumping related stresses in the water-level record during analysis of the data.
