Hurry Save The Murray!

Last week the community monitors were recording pH levels on the Finniss at “hot spots”.

Today John Yelland and Diane Bell visited the “acid pools” near the mouth of the Currency Creek. The Currency Creek has disconnected from the Goolwa Channel and is no longer running water.

Diane and John took five sets of readings of pH levels at pits (CC1a-e) from 88 metres from the banks to the water’s edge, about 280 metres from the bank.

Following the familiar pattern for acid sulfate soils (ASS), they found that closer to the bank the pH was low and as they moved closer to the water body, the pH increased.

Our most surprising finding was that the soil in the red depressions near the water’s edge was not acid, in fact it was alkaline.

The water in the pools near the water’s edge was acid.

Our suggestions
1. Continue monitoring to track whether the acid in the soil is being mobilised.
2. Do not disturb the soils near the banks and expose potential ASS
3. Mulch exposed areas
4. Lime upstream
