Saga of lead in Perth Children’s Hospital water supply

The ABC reports – Perth Children’s Hospital (PCH) lead contamination in water pipes supplying site – my Dec 2016 blog “Australian Government financial disasters” was discussing this issue early this month. How slow it is for truth to emerge.
The WA Building Commission has reported on the lead contamination issue with an 83 page pdf – Final report – Perth Children’s Hospital audit. Analytical results are presented in a 3 page pdf – Test results – Perth Children’s Hospital lead level patterns. The crux of the Commission findings are on page 27 of the audit section in their must read 6.4.1 Findings. High metal contents were found in the “dead leg”, a 52m dead end length of pipe open to the QEII ring main see page – see page 34 for table of analyses. The location of the “dead leg” is shown on the page 22 map – note proximity to PCH offtakes. The Commission also suspects new brass fittings in PCH as another source of lead contamination.
Page 2 of the test results shows 4 charts labelled North-South-East-West Blocks of presumably the PCH. The South Block chart in lower left shows an increasing trend of lead content. I do not recall that being addressed.

NIWA 3 month Outlook destroyed inside two weeks

Just as useless as our BoM – the NIWA March to May Outlook issued 1st March wrecked by heavy rain they never saw coming. They said –
Regional predictions for the March – May 2017 season
Northland, Auckland, Waikato, Bay of Plenty
Rainfall totals are about equally likely to be in the near normal (35% chance) or below normal range (40% chance).

The MetService shows that both Auckland and Hamilton had useful rain starting last Tuesday 7th March.

Wonthaggi seawater desalination plant using diesel generators

I saw this at Andrew Bolt. Last year the Vic Govt ordered 50GL water from Wonthaggi when there was no need for the water as dams look OK(despite the mad wasting of water on environmental flows). The sequence of news is –
Damaged power cable shuts down start up of desalination plant 30 Dec 2016
Desalination plant faces ‘substantial consequences’ over looming water deadline 11 Jan 2017
and now – Desal plant operator ships in diesel generators in desperate bid to deliver first water order 22 Feb 2017 You just could not make this up.
