I read it from either a Crikey or New Matilda article, Mark. I’m not sure that the water is going to run out in the timeframe you’re suggesting, but that the company won’t want to pay for the cost of continuing to do it.

I am also concerned re the open cut uranium mines, dust from site and tailings.
I am also concerned that these winds blew thru Maralinga bringing radioactive dust east.
Similar winds gathering in the NT will bring depleted uranium from the bombing ranges US B52s use to test their bunker busters, 2.3 ton of DU each, to the east. This stuff is there for 4 billion years, safely if left alone, but not if blown anywhere.

The main point about this storm is that we must realise that just because we put or do things 1000ks from anywhere, a big dust storm can bring these things to our front door. Right now the tailings are dampened according to Meski (above) but what happens when the water runs out in 10, 50, 100 years, and we get these big storms?
The answer? Don’t do stuff out there we do not want in our own backyard, becasue quite like that is where it will end up.

Currently the dust from tailings is being damped - but that’s not really good enough. I’d think the mine owners would need to be thinking of burial. Imagine asbestos type claims on a much vaster scale.

The possible role of dust storms in dispersing anthrax spores, which can survive for decades in the soil, was once a concern in New Zealand, and may still be. But biological contamination is not the only health concern created by Australian dust storms.

Dust blowing from central Australia and covering populated centres and agricultural land demonstrates that radioactive dust from uranium mine tailings could, and most likely will, be ingested and inhaled by citizens of Australia and New Zealand. It could also concentrated in the food chain, for example by animals grazing on dust contaminated fodder (this has been shown to occur with lead in particulate fallout downwind of lead smelters), and by filter feeders in marine and aquatic environments (this has been shown to occur with cadmium adsorbed onto fine particles of iron oxide).

The juggernaut seems a little too big to turn around now, so as usual we will probably just live - or die - with the consequences.

Very interesting Brian. I have been speaking to a retired lawyer next to a manure/soil batching plant in Rouse Hill area and he says now the general populace know how he feels most days. Imagine that - manure dust contrary to lazy derelict Blacktown City Council development consent - on your home and the nearby Rouse Hill Regional Park food preparation area. Makes Louie the fly sound positively hygenic. Tsk tsk.

The real health costs of this storm will not be apparent for some weeks yet. When I lived in Saudi Arabia the Shamaal, a yearly occurring strong Northerly wind always brought sand storms similar to today’s. A couple of weeks later there would be outbreaks of all sorts of illnesses brought about by bacteria that had been buried in the sand for some time, only to be spread far and wide by the winds. I suspect we will see a similar outbreak of illnesses in the weeks to come.

Is that a reference to Dune? Or the similar monsters in BeetleJuice?

Actually, Ben as you know I’m just away from the Sydney basin, thank God even on the best of smoggy days. So I think there is alot to your point about the bowl effect in story no.1. I drove through South Windsor at 1 pm and at the line of shops there were only two dusted cars parked, mine (south of Windsor) and one other. So they either hosed them quick smart or missed the dust storm.

I drove further north to Cattai toward Maroota say 40 km north west of Sydney cbd and there was little or no evidence of dust but signs of high wind at destination (dunny with no roof). Which suggests to me local air currents play a role in particulate pollution for good and ill and in Sydney that’s for ill.

“Why no advice to the NSW public to wear dust masks?”

Probably because it would conflict with the advice to stay at home. Thousands of people going out to buy dust masks. If you think it’s going to become a regular occurrence, buying some now might be prudent.

How do these particularate figures compare with the great Melbourne dust storm before Ash Wednesday 1983?

Why no advice to the NSW public to wear dust masks?
