Report on PFAS Contamination in New South Wales Water Catchments and Implications for Sustainable Development Goals

1.0 Executive Summary

A recent New South Wales parliamentary inquiry has revealed significant contamination of drinking water catchments with per- and poly-fluoroalkyl substances (PFAS), commonly known as “forever chemicals.” This report details the inquiry’s findings, the associated public health risks, and the direct challenges these issues pose to achieving several United Nations Sustainable Development Goals (SDGs), most notably SDG 3 (Good Health and Well-being), SDG 6 (Clean Water and Sanitation), and SDG 16 (Peace, Justice and Strong Institutions).

2.0 Inquiry Findings and Institutional Accountability

The investigation highlights critical lapses in water management and public communication, undermining progress towards SDG 16, which calls for effective, accountable, and transparent institutions.

• Premature Declarations: The inquiry found that Sydney Water had prematurely declared “no known PFAS hotspots” without conducting sufficient testing, a failure in due diligence.
• Detection of Contaminants: Subsequent testing confirmed the presence of PFAS in untreated water from sources including Medlow Dam in the Blue Mountains, leading to the shutdown of smaller water supplies.
• Erosion of Public Trust: Expert testimony criticized water agencies for a reactive, “tick-box” approach to safety guidelines rather than proactive health safeguarding, resulting in diminished community trust and anxiety among residents.

3.0 Public Health Impacts and SDG 3: Good Health and Well-being

The presence of PFAS in drinking water is a direct threat to SDG 3, which aims to ensure healthy lives and promote well-being for all at all ages. The persistent nature of these chemicals presents long-term health challenges.

3.1 Health Risks Associated with PFAS

• Bioaccumulation: PFAS are known as “forever chemicals” because they do not break down in the environment or the human body, leading to accumulation over time.
• Adverse Health Outcomes: Scientific studies have linked PFAS exposure to severe health issues, including:
  • Various forms of cancer
  • Immune system disruption
  • Thyroid disease
  • Reproductive and developmental problems

4.0 Challenges to SDG 6: Clean Water and Sanitation

The contamination directly contravenes the primary objective of SDG 6, specifically Target 6.1, which aims for universal and equitable access to safe and affordable drinking water. The situation in New South Wales underscores the vulnerability of water systems to chemical pollution and the need for robust management frameworks.

• Compromised Water Safety: The detection of PFAS demonstrates a failure to protect water sources from chemical pollution, compromising the safety of public water supplies.
• Lack of Transparency: Affected communities reported feeling uninformed and excluded from decision-making processes, highlighting a gap in ensuring equitable access to information regarding water quality.

5.0 Recommendations for Mitigation and Alignment with SDGs

The parliamentary committee issued 32 recommendations aimed at addressing the contamination and preventing future occurrences. These measures are critical for restoring public trust and realigning state efforts with SDG targets.

5.1 Key Recommendations

1. Implement Routine Testing: Establish a comprehensive and routine PFAS testing protocol across all NSW water catchments to ensure ongoing monitoring and compliance with SDG 6.
2. Enhance Inter-Agency Coordination: Improve coordination between state and federal agencies to create a unified and effective response to chemical contamination, strengthening institutional capacity as per SDG 16.
3. Support Affected Communities: Offer voluntary blood testing for residents in affected areas to address health concerns and improve transparency, contributing to the well-being objectives of SDG 3.
4. Review National Guidelines: Undertake a comprehensive review of how Australia implements drinking water guidelines to ensure they are proactive health safeguards rather than minimum compliance standards.

5.2 Consumer and Policy Actions for SDG 12

Individual and collective actions can support broader policy goals aligned with SDG 12 (Responsible Consumption and Production) by reducing demand for and use of PFAS.

• Public Inquiry: Residents can request information from local water providers regarding PFAS testing and results.
• Filtration: The use of certified home water filters can reduce exposure to PFAS.
• Policy Advocacy: Supporting policy initiatives to phase out the use of PFAS in consumer and industrial products is crucial for preventing future environmental contamination.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

1. SDG 3: Good Health and Well-being
   • The article directly connects the presence of PFAS chemicals in drinking water to significant health risks. It states that these synthetic compounds are “linked to health issues like cancer and immune system disruption” and also mentions “thyroid disease, and reproductive issues.” This highlights a direct threat to the well-being of the residents of New South Wales.
2. SDG 6: Clean Water and Sanitation
   • The central theme of the article is the contamination of drinking water sources. The discovery of “PFAS… in local drinking water catchments” and the subsequent shutdown of “smaller water sources” clearly points to a failure in ensuring the safety and quality of water, which is the core objective of SDG 6.
3. SDG 12: Responsible Consumption and Production
   • PFAS are described as “forever chemicals” because “they don’t break down in the environment or human body.” This points to unsustainable production and consumption patterns where hazardous chemicals are released into the environment without proper management throughout their lifecycle, leading to long-term pollution of natural resources like water.
4. SDG 16: Peace, Justice and Strong Institutions
   • The article highlights institutional failures and a lack of transparency. It mentions that Sydney Water “prematurely declared there were ‘no known PFAS hotspots'” and that a water safety expert “criticized agencies for treating drinking water guidelines as a ‘tick-box exercise’.” Furthermore, the community’s feeling of being “uninformed and excluded from decision-making” points to a breakdown in accountable and inclusive governance.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. Under SDG 3 (Good Health and Well-being):
   • Target 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination. The article’s focus on PFAS, which are hazardous chemicals in water linked to cancer and other diseases, directly relates to this target.
2. Under SDG 6 (Clean Water and Sanitation):
   • Target 6.1: By 2030, achieve universal and equitable access to safe and affordable drinking water for all. The contamination of tap water in New South Wales means the water is not “safe,” directly challenging the achievement of this target for the affected population.
   • Target 6.3: By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials. The presence of PFAS in water catchments is a clear example of water pollution by hazardous chemicals that needs to be addressed to meet this target.
   • Target 6.b: Support and strengthen the participation of local communities in improving water and sanitation management. The article notes that “Communities living near contaminated sites have reported feeling uninformed and excluded from decision-making,” indicating a failure to meet this target.
3. Under SDG 12 (Responsible Consumption and Production):
   • Target 12.4: By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle… and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment. The persistence of “forever chemicals” in the water supply demonstrates a failure in the sound management and disposal of these chemicals, leading to their release into the environment and subsequent human exposure.
4. Under SDG 16 (Peace, Justice and Strong Institutions):
   • Target 16.6: Develop effective, accountable and transparent institutions at all levels. The criticism that Sydney Water made premature declarations without adequate testing and that agencies are not proactive suggests a lack of effectiveness and accountability.
   • Target 16.7: Ensure responsive, inclusive, participatory and representative decision-making at all levels. The community feeling “let down” and “excluded” directly contradicts the principle of inclusive and participatory decision-making that this target promotes.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

1. For SDG 3 & 6 (Health and Water Quality):
   • Levels of PFAS in water: The article explicitly mentions that “tests revealed levels of PFAS in untreated water.” This measurement is a direct indicator of water contamination (Indicator 6.3.2) and the safety of drinking water (Indicator 6.1.1). Progress would be measured by the reduction of these levels to below safety standards.
   • Voluntary blood testing: The recommendation for “voluntary blood testing for concerned residents” implies an indicator for human exposure to hazardous chemicals. The results of such tests could measure the extent of the population’s exposure and the effectiveness of mitigation efforts.
2. For SDG 16 (Strong Institutions):
   • Implementation of recommendations: The article states the committee report issued “32 recommendations.” The number and effectiveness of these recommendations that are implemented by government agencies can serve as a quantitative indicator of institutional responsiveness and accountability.
   • Level of community concern/trust: The article notes, “We recognize there is community concern.” While qualitative, measuring shifts in public perception, trust in water authorities, and the feeling of being included in decision-making can serve as an indicator of progress towards more transparent and participatory institutions.
3. For SDG 12 (Responsible Consumption):
   • Routine PFAS testing: The recommendation for “routine PFAS testing across NSW” implies an indicator for monitoring the release of hazardous chemicals into the environment. The frequency and results of these tests would measure the extent of the problem and the effectiveness of policies aimed at phasing out PFAS.
