<div style='text-align:Left;'><div><div><p><span>The SNG Response theme grid is the relative vulnerability map for the Surficial Aquifer System. It was calculated using the ArcSDM extension and applying the weights of evidence method. A relative vulnerability class field is also in the table so that the grid can be symbolized into 4 vulnerability classes. These classes were developed based on weights of evidence vs. cumulative area breaks.</span></p></div></div></div>
