This study focused on thermal characteristics of the ground water and recharged surface water at The Upjohn Company's (now Pharmacia and Upjohn) Portage Road manufacturing facility. Major objectives were: (a) a compilation and graphical evaluation of historical lower aquifer ground water temperatures; (b) estimates of thermal energy introduced into the ground water system through recharge from Upjohn Pond, and predictions of future production well discharge temperatures; (c) an evaluation of hydraulic conductivity related to changes in water density and viscosity influenced by variable temperature; and (d) the stratigraphy beneath Upjohn Pond.
Records reveal increasing ground water temperatures through time in response to the recharge of non-contact cooling water at the site. Three methods were employed and estimated thermal input via Upjohn Pond to be 1.81E+10, 7.71E+10, and 1.38E+ 11 BTU's. Future discharge temperatures are predicted to be 53.2 by 1997. The temperature of the recharging pond water is a significant factor in the value of the hydraulic conductivity. The stratigraphy beneath the pond indicates the basal pond clay layer and the upper aquitard are separate lithologic units.
