1. INTRODUCTION<br />
1.1 Overview<br />
<strong>POLYMIN</strong> is an advanced numerical model for solving reactive mass transport problems. The<br />
model can be used to solve one or two-dimensional mass transport problems within a variety <strong>of</strong><br />
hydrogeological systems. <strong>POLYMIN</strong> was originally developed as a research tool to study the<br />
behaviour <strong>of</strong> acid mine drainage or reactive contaminant plumes within porous media (see Figure 1).<br />

<strong>POLYMIN</strong> will run on any computer although it is recommended that the model be run on at least a<br />
Pentium III/500 MHz machine. The memory requirements depend on your application. 2D<br />
simulations may require on the order <strong>of</strong> 64-128 Mbytes.<br />
