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.

Floods but no Feb 2017 rain recorded yet by BoM in Perth dam catchments

How bizarre is this – heavy rain and floods starting 9/10 Feb – but no Feb 2017 rain recorded yet – while rain is so easy to measure and record.
[1] BoM station Mundaring Weir 9031 has no data later than March 2016
[2] BoM station Victoria Dam 9216 is missing March and Jun, Oct to Dec 2016 nothing yet for 2017
[3] BoM station Churchman Brook 9010 has many periods in 2016 where no daily readings were taken – arrows. And no data yet for 2017
[4] BoM station Wungong Dam 9044 has all months for 2016 now and Jan 2017 as well(applause).
[5] BoM station Serpentine Main Dam 9115 has nothing after May 2016 – nothing for 2017 yet.
Can anybody recall anything like this tardy recording by the BoM anywhere else?
The rain that caused the floods from around York and Northam we saw on TV news was mostly from 9 Feb to 11 Feb and left this broad band of 100mm+ rain from Perth SW into the wheatbelt.

Lead reported in water supply to Perth hospitals

This story started last year with lead reported in the water onsite at the brand new Perth Children’s Hospital which has not yet been handed over to the WA State Govt. The subject came up in comments at my pre-Christmas post – Australian Government financial disasters – Philip just pointed out two new articles – Perth Children’s Hospital builder John Holland denies hospital lead fault 26 Jan 2017 – and – Joe Spagnolo: Lead weight in Colin Barnett’s poll bid 28 Jan 2017. I see this as mainly between Water Corporation and the Contractors, not so much the politicians who tend to be lawyers not scientific people. IMHO the best way forward is – The Govt must release all analytical data relevant over 2015 and 2016 including sampling dates, locations, quantity collected, storage details, if surplus samples still exist, the analytical method, detection limits and date of assay, results for all elements assayed for including quality control results and the laboratory which conducted the analyses. Then many experts world wide will examine the results and might offer constructive comments.

Pauline Hanson to visit Wellington Dam

Thanks to Beachgirl for this marvelous news from The West Australian. My post from last May – Plans to reduce WA wheatbelt salinity and utilize Wellington Dam with link to Agritech Wellington Dam Water Recovery Project on the WayBack machine. Any WA people interested in rational water policies should get in the car on Friday and visit Collie and Wellington Dam with Pauline Hanson. Help to make the day a success for Pauline and WA people.
