Answers wanted over cause of lead leaching into drinking water

Sustainable Development Goals and Critical Infrastructure Failures in Queensland

Key Points:

• Lead has been detected in Yarrabah’s schools, health facilities, and some houses
• Authorities say there is no evidence drinking water has contributed to elevated lead in blood levels
• But the Queensland government was aware of critical infrastructure failures more than a year before lead was discovered in the water

The Queensland government received warnings about critical infrastructure failures over a year before lead was found in the tap water of Yarrabah, Australia’s largest Aboriginal community.

In May, lead levels up to 12 times the safe limit were detected in tap water at schools in Yarrabah, located in far north Queensland. Elevated lead levels were also found in water at the town’s health services and some homes.

Queensland Health suspects that corroded pipes or fittings are the source of contamination, causing heavy metals to leach into the water. They claim that the recorded levels are safe when taps are flushed for 30 seconds.

Documents reveal that the automatic pH system, responsible for controlling the acidity of the town’s water supply, had been broken for over a year before the discovery of heavy metals.

The Yarrabah Aboriginal Shire Council reported these issues to the government regulator in July of the previous year. They stated that water samples taken between January 2021 and April 2022 from various outlets in the town failed to meet Australian Drinking Water Guidelines due to corrosiveness.

The council has been actively seeking support and funding from the state government for a water treatment plant upgrade, including pH correction.

Tropical Public Health Service director Richard Gair acknowledges that corrosive water may contribute to lead leaching in fittings but emphasizes that no conclusions have been drawn yet.

Yarrabah’s water supply comes from bores and is naturally acidic, which increases the likelihood of pipe corrosion and metal leaching.

The Queensland government has allocated $1.25 million in funding to upgrade the water treatment plant in Yarrabah, with an additional $3.2 million for various water, wastewater, and solid waste projects.

Elevated lead levels have been detected in both adults and children in Yarrabah. Around 250 people have been tested so far, with approximately 11 individuals showing elevated results. However, only 18 out of more than 1,800 children in the community have been tested.

The Cairns and Hinterland Hospital and Health Service states that there is no evidence linking the consumable water to the elevated lead levels. Environmental and health factors are believed to be contributing to these results.

Outreach worker Kaylene Jackson reports that two of her grandchildren and a family friend have elevated lead levels in their blood. The health service attributes one child’s levels to exposure to a lead fishing sinker but has not provided an explanation for the other two children.

Cynthia Barlow, a lead contamination researcher at the University of Adelaide, explains that lead fittings are common in Australian homes but become more problematic when the water has a low pH. She emphasizes the need for widespread testing in Yarrabah to determine the extent of the problem.

Jason King, director of clinical services at Gurriny Yealamucka Health Service, agrees that there should be a better understanding of the water quality issues in the community. He calls for comprehensive investigations to identify the source of the problem.

It is crucial to address these issues promptly as long-term exposure to even low levels of lead can have lifelong impacts on health, including developmental and behavioral issues.

Community Concerns and the Importance of Testing

Residents of Yarrabah are demanding answers regarding the water issues in their community. They express frustration and a desire for more information and communication about the situation.

Health authorities are urged to be proactive in addressing the problem and conducting comprehensive testing to ensure the safety of the community. Immediate action is necessary to prevent further damage and protect the health of residents.

Sustainable Development Goals

This situation in Yarrabah aligns with several Sustainable Development Goals (SDGs) established by the United Nations:

1. No Poverty
2. Good Health and Well-being
3. Clean Water and Sanitation
4. Sustainable Cities and Communities
5. Partnerships for the Goals

Addressing the critical infrastructure failures and lead contamination in Yarrabah is essential for achieving these SDGs. It requires collaboration between government entities, health services, and community members to ensure access to safe drinking water and protect the well-being of individuals.
