Appendix C shows all bacteriological tests in HYDSYS. Coliforms have been detected in 13 of 31 samples tested, a high detection rate. Further study would be needed to determine what the sources of contamination were for particular bores. Faecal coliforms have been detected in 6 of 36 samples tested. The two very high faecal coliform counts came from RN 6518. It is clear that the Town Basin could not now be used for potable town supply without disinfection. 5.4.5 Viral No viral testing in the basin is known, and it is very unlikely that any has been carried out. 5.4.6 Radionucleides During the period of atmospheric nuclear weapons testing regular checks were made of the radioactivity of Alice Springs water supply, as for many other Australian towns. No records of analyses for uranium, radium, or for gross alpha or beta activity could be found in the HYDSYS database. Two determinations of gross alpha and beta activity in 1985 were found in a data file and are shown in Appendix C. Levels are well below those of concern. 0 2000 4000 6000 8000 Cl in mg/L 0 50 100 150 200 250 N O 3 i n m g/ L Nitrate vs Chloride Groundwater Todd River at Anzac Figure 23 Nitrate versus Chloride 5.4.7 Stable isotopes Berry (1992) shows 18O and 2H compositions for samples from the Town Basin.
