Nonlinearity and nonconvexity are two major characteristics of groundwater quality
management models. The classical solutions of such problems require enormous
computational effort without ensuring a global optimum. To circumvent this problem, the
outer approximation method, a global optimization technique, was introduced to solve
groundwater quality management problems characterized by a nonconvex objective
function with minima at the boundary of the feasible region and constraints that have
convex or nonconvex behavior. In this paper, a more sophisticated and computationally
efficient approach for the case of the nonconvex constraints is presented. To illustrate
the efficacy and efficiency of this new approach, a hypothetical and a field-scale problem
are considered
