Abstract

Water supplies from confined aquifers, such as those pumped from the Memphis aquifer, are typically less influenced by modern recharge than those from unconfined aquifers. However, zones of hydraulic connection believe to be occurring through the confining unit between a shallow aquifer and the deeper Memphis aquifer adjacent to the McCord well field in Memphis, Tennessee. Locally, the shallow aquifer experiences a depression in the water table and Fletcher Creek experiences a loss in discharge. To confirm and further research this anomalous depression in the water table and the local flow paths that are occurring, a combination of physical data, chemical data and age-dating results were analyzed. Considered together, the data suggest a strong linkage between stream loss in Fletcher Creek, the loss of ground water storage in the shallow aquifer and the presence of modern water in production wells in the Memphis aquifer at the McCord well field.
