In this paper we analyze a fully practical piecewise linear finite element approximation involving numerical integration, backward Euler time discretization, and possibly regularization and relaxation of the following degenerate parabolic equation arising in a model of reactive solute transport in porous media: find u(x,t) such that u + [(u)] - δu = f in ω (0,T], u = 0 on ω (0,T] u(',0) = g(.) in ω for known data ω R, 1 ≤ d ≤ 3, f, g, and a monotonically increasing C(R) C (-,0) (0,) satisfying (0) = 0, which is only locally Hölder continuous with exponent p (0,1) at the origin; e.g., (s) [s] . This lack of Lipschitz continuity at the origin limits the regularity of the unique solution u and leads to difficulties in the finite element error analysis.
