NIWA “dryer than average” New Zealand rain Outlook looks under threat – again

The NZ climate prediction maestros look to have dropped another dodgy one – to my untrained eye anyway.
Stuff says – Live: Christchurch declares state of emergency, orders evacuation as floods rise – and the NZ Herald with hopeless front page – Winter storm chaos: What you need to know
If I read the COLA forecast right – more rain this coming week. Not long since – NIWA 3 month Outlook destroyed inside two weeks 11 Mar 2017

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.
