The manganese concentrations have however, been decreasing with time. For example, manganese concentrations in samples taken in August, 1981 averaged approximately 3.6 mg/L, whereas samples taken in June, 1984 averaged approximately 0.21 mg!L. The AWRC/NHMRC recommend desireable levels of 0.5 mg!L, with long term objec~ives of 0.05 mg!L. Also, with the removal of highly polluted lakes from the Rum Jungle area and the unlikely chance of any significant mining or industrial development in the area, in the opinion of Water Resources Division, it is unforseeable that there will be any future pollution of the groundwater. In the unlikely event of any development proposals in the area, consideration should be given to the risk of pollution of the aquifer system. 20
