Ice lab leached deadly toxins into Sydney’s water catchment area

Daily Telegraph Ashlee Mullany 28 August 2015

CHEMICALS from the biggest ice lab ever found in NSW leached into the catchment area that feeds into Sydney’s water supply at Warragamba Dam west of the city.    Court documents reveal waste and “methamphetamine byproducts” from the lab ­polluted the Yerranderie Catchment area, a pristine water supply that flows into Warragamba Dam.

Chemical experts carried out testing of the soil at the ­Yerranderie site after noticing dead trees in the area and ­allegedly found traces of caustic liquids and methamphetamine leaching into groundwater.

Rivers of red threaten the future of the reef

Radio National Background Briefing Gregg Borschmann 30 August 2015

New scientific research reveals the flood plumes from tropical rivers are travelling further and hanging around longer than previously thought, killing young corals and impacting reef growth.  In addition, the sediments—and the attached nutrients—are linked to the latest outbreak of crown of thorns starfish on the reef.

Chemicals ‘build up’ in breast milk

The Australian John Ross August 21, 2015

A Harvard University public health expert says Western mothers should limit breastfeeding to a few months, after his team found that contaminants had accumulated in the blood of breastfed babies.
The Danish and American study found that a widely used class of industrial chemicals, known as “perfluorinated alkylate substances” or PFASs, had seeped into the bloodstreams of babies fed on mothers’ milk.
“We knew that small amounts of PFASs (could) occur in breast milk, but our serial blood analyses now show a build-up in infants the longer they are breastfed,” said Philippe Grandjean, an adjunct professor at Harvard’s Chan School of Public Health.

Tests into mysterious Gold Coast Seaway spill

Brisbane Times Tony Moore August 12, 2015

A large plume of brown, dirty water seen in Southport’s Gold Coast Seaway this week is being investigated by government and university experts.
The huge brown water spill was not sewage, a Gold Coast Waterways spokesman said, but the source of the mysterious brown cloud of dirty water was unknown.
On Monday the huge wash of brown water could be seen kilometres out to sea after it appeared in the Gold Coast Seaway to the north of Southport.
Gold Coast City Council has two outflows on either side of the Gold Coast Seaway where it discharges treated sewage.
