Iron contamination at Kangaloon Aquifer site.

SANDBAG LEVEE-BANK,
TO SETTLE THE WATER
PUMPED FROM THE BORES.
Last week, the water being pumped from the Kangaloon Aquifer had turned brown, from iron. That there is a high iron content in the water is completely normal, and was expected by the Engineering Report commissioned by the SCA.

What is not normal, and not correct procedure, is that the iron ought be dumped onto the soil.

The Engineering Report proposed an aeration tank, with a sludge collection system, to prevent contamination of the local area.

I asked Mr John Ross, the SCA's Project Manager, after the Bowral Meeting, why they were not using the aeration/settlement tank system. Hs reply was: "No iron in that water".
You can now judge for yourself how good Mr Ross's technical expertise is.
If he is wrong on this issue. What else is he wrong on?
SANDBAGS ON TOP EDGE OF THE SETTLEMENT POND.
CLEAN ONES ARE ABOVE THE WATER LEVEL.
LOWER ONES ARE STAINED BY THE IRON.
Unfortunately, in their sloppiness (or indecent haste) the SCA have not bothered to install this proposed aeration tank, but just spill the water out over a metal tray, and allow it to spill onto the ground, then to run over the ground, through some Lomandra (rushes), and through another pipe, into the creek.
What is happening is that the iron, when "aerated" forms a form of iron oxide (a rust-like precipitate), and settles out into the ground. The question is, what will the SCA do to prevent this contamination spreading, or, indeed to remediate the area, after they have finished the "trial pumping"?
Site on Day 1 of pumping.
After the heavy rain,
the first water pumped was clean.
I emailed Mr Graeme Head, Chief Executive of the SCA, last week, (15 March) about this issue, but have had no reply, as yet.

So, I am now turning this into an "Open Letter" to Mr Head - in the hope that it might provoke an answer from him.
I will copy my original email to the local ALP Member for Kiama, Mr Matt Brown, and to Ann Sudmalis, Liberal Candidate, to see if either of them can get a reply for me.
