Perth Children’s Hospital: New lead test failures in drinking water highlight murky health transparency

10/9/25: Adrian Rauso (The West Australian)

There is no clearer example that WA’s health system is veering off a cliff than Roger Cook prematurely declaring lead issues at Perth Children’s Hospital were “well and truly in the rear-view mirror”.

Premier Cook made the definitive statement on Friday after The West Australian revealed 11 samples of PCH’s drinking water taken between January 2023 and March 2024 had exceeded the lead safety benchmark allowed under the Australian Drinking Water Guidelines.

But on the same day the Premier made his ‘mission accomplished’ remark, PCH’s management became aware of five new exceedances of the toxic metal from a batch of water testing carried out during August and last week.

The blunder was just the tip of the iceberg in a saga plagued by a titanic lack of transparency.

WA’s Chief Health Officer Andrew Robertson has maintained that elevated lead levels over the past three years posed “no risk” to patients or staff, yet scarce detail has been provided as to how these conclusions have been reached.

Health Minister Meredith Hammat initially refused to disclose how much the recent water samples overshot the ADWG lead threshold, before eventually bowing to pressure. One sample was nearly four times the limit.

This threshold of 0.005 milligrams of lead per litre is not an arbitrary number, it’s been set with PCH’s core patient demographic in mind.

“A drinking water guideline for lead of 0.005 mg/L was set with the general aim of reducing or minimising lead exposure to a blood-lead level target of less than five micrograms per decilitre,” a spokeswoman for the National Health and Medical Research Council, which oversees the ADWG, said.

“This approach was consistent with current Australian science policy to minimise exposure to lead in the most sensitive population groups — infants, children and pregnant women.”

Lead in PCH’s water is not the only issue crippling WA’s health system. Ambulance ramping is at unprecedented levels and, across the road from the children’s hospital, Sir Charles Gairdner is falling apart.

For a State that enjoyed $9.9 billion of iron-ore royalties last year this situation is simply not good enough. Maybe it’s time to put the Burswood racetrack in the “rear-view mirror” and focus on fixing our broken hospitals?

Water Corporation Reassures Perth Residents Over Drinking Water Safety After PCH Lead Concerns

Water Corporation has sought to reassure Perth residents that the city’s drinking water is safe, following reports of lead contamination linked to plumbing at Perth Children’s Hospital (PCH).

The utility said no lead above guideline levels has ever been detected in its metropolitan water supply scheme since records began 18 years ago.

It stressed that the water supplied to households across the Perth metropolitan area “meets all health-related requirements and is completely safe for use.”

Water Corporation supplies about 290 billion litres of drinking water each year to nearly two million people.

More than 66,000 water samples are collected annually from sources, treatment plants and points along the network, with analysis conducted by independent laboratories in line with Department of Health requirements.

While routine annual testing has shown no issues with lead, the Corporation said it began additional testing near the hospital site in response to concerns raised in 2016.

These results also showed no detections of lead.

“As a further precautionary measure, we have increased the frequency of lead testing across the entire metropolitan area from annually to quarterly,” Water Corporation said.

“Again, there were no detections of lead above guideline levels.”

The Department of Health regulates drinking water quality in Western Australia and audits Water Corporation’s testing and reporting systems.

Water Corporation clarified that it does not directly supply water to the hospital.

Instead, the utility supplies the broader QEII Medical Centre site through two meters, with internal distribution managed via a shared private network known as a “ring main.”

Responsibility for water quality beyond the supply point rests with site owners and plumbing regulators.

The corporation said it installed additional sampling points at the QEII complex in 2016 after being alerted to lead issues during construction of PCH.

A review of earlier testing also found no detection of lead within the wider Mt Eliza Zone supply.

“Supplying safe drinking water is always our highest priority,” the utility corporation said.

Lead in water at Perth Children’s Hospital prompts national investigation

 
April 1, 2018 2:00AM

A NATIONAL probe into whether toxic lead is leaching into drinking water from plumbing inside Australian buildings is under way.

The Australian Building Codes Board has commissioned a research project to investigate potential sources of lead in plumbing materials.

Prompted by the Perth Children’s Hospital lead fiasco and concern about lead contamination in other buildings, the national regulator was asked to investigate the issue by the Building Ministers Forum, a body of Commonwealth, State and Territory ministers.

A recent report into the PCH debacle, stemming from a parliamentary inquiry, called for “urgent action to clarify whether the lead exceedances at PCH was an isolated event”.

Lead leaching from brass plumbing fittings “is a potentially significant public health issue”, it added.

ABCB chief executive Neil Savery said the project would also investigate the effect of water chemistry, quality and temperature on plumbing products/materials, the cumulative effect of multiple products/materials in a water service and the interaction of different products/materials.

The probe will also consider whether the relevant Australian Standards afford enough protection.

Australian Standards allow up to 4.5 per cent of lead content in materials that come into contact with potable water, whereas the US only allows up to 0.25 per cent because of increasing evidence of harm caused by low levels of lead in drinking water. Cheaper brass contains more lead.

WA Master Plumbers chief executive Murray Thomas said following the American step by reducing lead content to almost zero was the “logical pathway”.

However, the WA Government is still resisting calls to investigate the presence of lead in drinking water fountains at Optus Stadium.

Lead levels up to 14 times the Australian Drinking Water Guideline maximum of 0.01mg/L were found in samples collected by The Sunday Times and tested at accredited laboratories.

Building Commissioner Ken Bowron said the Optus Stadium fountains complied with Australia’s WaterMark Certification Scheme. Fountains at Whiteman Park closed last June after sampling revealed elevated lead levels. The taps and fittings, found to be the source of the contamination were also WaterMarked.

Deadly legionella bacteria found in Perth Children’s Hospital drinking water

A new problem has struck the trouble-plagued Perth Children’s Hospital with the potentially deadly legionella bacteria detected during routine water testing, as the Health Department grapples with an ongoing lead contamination issue.

Child and Adolescent Health Service chief executive Robyn Lawrence confirmed to the ABC that 14 instances of legionella had been found.

The bacteria was discovered in warm water outlets, a shower head and a drinking water fountain.

Legionella is found naturally in lakes and streams but can become a health concern when it grows and spreads in human-made water systems, including large plumbing systems.

People can contract Legionnaires’ disease — a severe, occasionally lethal form of pneumonia — when they breathe in small droplets of water that contain the bacteria.

Last year, one man died and 15 people contracted Legionnaires’ disease when the bacteria was discovered in two water cooler towers in the Sydney CBD.

The WA Australian Medical Association President Omar Khorshid said a Legionnaires’ disease outbreak could be serious.

“There have been deaths in Australia,” Dr Khorshid said.

“Unfortunately though legionnaires can affect the young and it can affect the healthy, so it’s very important to have it eradicated from the water systems.”

In a statement Dr Lawrence the “results detected were at the low end of the accepted scale” and the relevant authority would implement remediation strategies, but she did not detail what that would involve.

The positive samples were collected on October 19 and 20.

“The likely reason is a combination of low hot water temperatures and restricted flow due blocked aerators/inline strainers and/or a lack of flushing resulting in a biofilm build-up at the outlet that harbours and supports the colonisation of legionella,” she said.

A litany of problems

It is the latest in a string of issues for the hospital, ranging from asbestos in the roof panels to contractor disputes and faulty water piping.

The main issue that has prevented the hospital opening is lead contamination in the drinking water, which remains unresolved.

The basement of the hospital has been flooded by a burst pipe, 900 fire doors have had to be ripped out and replaced, and key members of the hospital’s leadership team have resigned.

It is currently costing taxpayers $6 million a month as it sits idle with no patients — that includes about $6000 a day in power bills and $700,000 a month to contractor Capella Parking for car bays that are sitting idle.

On top of these issues, WA health officials recently admitted a raft of other construction issues at the hospital during a budget estimates committee hearing.

These included problems at the on-site childcare facility, mental health unit, isolation rooms and anaesthetic gas delivery.

The WA Government is bracing itself for a lengthy legal battle in its bid to recoup millions of dollars from the head contractor of the hospital, John Holland, over long delays to the project.

John Holland in return is seeking $300 million in compensation from the Government for changes to the project.

The $1.2 billion project is now running more than two years behind schedule, and is not expected to open until the first half of 2018.
