Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Temperature-dependent reactive mass transport is simulated numerically in three dimensions. The multicomponent chemistry and heat transport model is based on the Galerkin finite element technique with symmetric time-weighting and uses a preconditioned conjugate gradient matrix solver. The groundwater geochemistry, assumed governed by equilibrium reactions, is coupled with mass transport using a sequential physical-chemical approach. A large-scale 3D simulation of the Borden thermal injection experiment helps illustrate the complex reactions associated with shallow ATES systems, including changes in groundwater pH and temperature-induced carbonate precipitation"--Abstract. gccst Groundwater gccst Geochemistry gccst Models Frind, E.
