A simple water analysis I did of the Dee River last year (PDF), testing the pH, conductivity and total dissolved solids (TDS). A summary of the results are shown below.
|Water Quality Test||Dee River Sample||Bore Water Sample|
|Total Dissolved Solids (measured by evaporation)||2050 mg/L||950 mg/L|
|Conductivity (measured by probe)||2120 mS/cm||1602 mS/cm|
But as can be seen from the photos below, the Dee River is still far from healthy.
