Abstract

"Carbonate rock aquifers underlie many parts of Missouri. As population and water use increase, these aquifers will increase in importance as sources of water supply. The purpose of this study is to investigate the applicability of barometric calculations and a variety of pump test evaluation equations to a shallow confined doloii mite aquifer. The aquifer is the upper Gasconade Formation of Lower Ordovician age in the vicinity of Norman Creek, south central Phelps County, Missouri.

The response of water level to atmospheric pressure showed that the carbonate aquifer in this study site has a rather high barometric efficiency (Bav = 75%) and low porosity (aav = 0.96%). The results from pump tests showed low values of transmissibility (Tav = 20 gpd/ft), permeability (Kav = 0.155 gpd/ft2) and storage coefficient (Sav = o. 00013). Little variation was found between fully penetrating and partially penetrating nonequilibrium formulae, but a wide variation exists between results obtained from the equilibrium formulae. The results of these tests give an order-of-magnitude estimate of the hydrologic characteristics of the aquifer, and the advantage and disadvantage of applying different boundary conditions to the same data"--Abstract, p. ii
