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.
