Supervising Scientist Environmental Monitoring Program
The Supervising Scientist's interpretation of the data in these charts is available at Explanatory notes on physical and chemical indicators of water quality.
The uranium limit of 6 µg/L recommended by the Supervising Scientist has been derived using local ecotoxicological data. The limit must not be exceeded. Please note that the limit is far above the range shown on the charts, but the scale on the right hand axis shows how the measured concentrations compare to the limit.

Due to a natural source of magnesium between the upstream and downstream monitoring points in Ngarradj Creek, the Supervising Scientist has recommended a guideline value of 0.76 mg/L determined statistically and which may be extended occasionally due to natural events.
