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.

One thought on “Lead reported in water supply to Perth hospitals”

  1. For those not familiar with the situation. The water supply for the new Children’s Hospital comes directly from the Mt Eliza Reservoir in nearby Kings Park.

    This is the situation a I understand it.

    Mt Eliza was the first water supply reservoir in Perth. Although, the original reservoir built in 1890 no longer exists, and the oldest part of the reservoir currently in use, dates to just after 1900. There are in fact 3 reservoirs, with supply coming from the newest and largest (built around 1970), and the 2 older reservoirs are used to feed water into the newest reservoir.

    I’ve suggested that the oldest parts of the Mt Eliza reservoirs were built prior to the awareness of lead in water being a problem and contain lead. Lead pipes previously common, started to be banned in the 1920s. I don’t have a date for WA.

    The presumably episodic feeding of water from the older reservoirs into the newer supply, may be the reason for the conflicting test results of lead being in the supply (or not). As well as I assume increased frequency of water transfer from the older reservoirs as water demand increased with the new hospital.

    It’s unfortunate this has come just prior to an election, as it will become a political football.
