The very high nitrate in the north east corner is a single analysis from a shallow well that was probably badly polluted. Figure 23 shows the relation between nitrate and chloride. It can be seen that there is a small population of waters with high nitrate and low chloride. The nitrate could not have been derived by evaporative concentration of river water, and is either a result of pollution, or possibly direct infiltration of nitrate rich waters. The very high chloride waters have low nitrate. 5.4.1.3 Potassium and Sodium Figure 21 shows the relationship of potassium and sodium concentrations. For the Todd at the Anzac and Heavitree gauging stations there is a clear power relationship. The groundwater samples are far more scattered, but show a very similar power relationship. The reason for this is not known. 29
