Children and Contaminated Water: Understanding the Legal Responsibility to Protect Vulnerable Communities

Access to clean and safe water is essential for every community. However, when drinking water becomes contaminated, the consequences can extend far beyond inconvenience. Families may face serious health concerns, children may become ill, and communities may be left without a reliable source of safe water.

Children are particularly vulnerable because their health and development can be affected by exposure to unsafe water. In communities where access to alternative water sources is limited, the risks may be even greater.

In South Africa, access to sufficient water is a constitutional right. Government institutions, municipalities and other responsible parties have legal obligations relating to water provision, water quality and pollution prevention. Understanding these responsibilities is important when contaminated water places children and vulnerable communities at risk.

The constitutional right to safe water

Section 27(1)(b) of the Constitution of the Republic of South Africa, 1996, provides that everyone has the right to have access to sufficient food and water. Section 27(2) requires the state to take reasonable legislative and other measures, within its available resources, to progressively realise this right.

This means that access to water is not simply a matter of convenience. It is a constitutional issue that affects people’s dignity, health and ability to live safely.

The Constitution also recognises children’s rights under section 28. Every child has the right to basic nutrition, shelter, basic healthcare services and social services, as well as protection from maltreatment, neglect, abuse or degradation. Section 28(2) further provides that a child’s best interests are of paramount importance in every matter concerning the child.

When children are exposed to contaminated water, these constitutional protections become particularly relevant. Authorities responsible for water services must consider the potential effects on children and other vulnerable members of the community when responding to water quality concerns.

Why contaminated water presents a serious risk to children

Contaminated water may contain harmful microorganisms, chemicals or other substances that make it unsafe for human consumption or domestic use.

Children may be exposed through drinking water, food preparation, bathing, washing or playing in contaminated water sources. Depending on the contaminant and level of exposure, the consequences may include gastrointestinal illness, infections and other health complications.

The risks may be more difficult for families in low-income communities to avoid. Where households have no affordable alternative source of water, parents may have little choice but to rely on the available supply, even when concerns about its quality have been raised.

Schools, early childhood development centres and public facilities also require access to safe water. Contamination affecting these facilities can expose many children at once.

The impact is therefore not limited to individual households. It can become a broader public health and community safety concern.

Who is legally responsible for providing safe water?

Responsibility depends on the source of the contamination, the circumstances and the duties imposed by law.

1. Municipalities and water services authorities

Municipalities designated as water services authorities have responsibilities relating to access to water services within their areas.

Section 3 of the Water Services Act 108 of 1997 recognises everyone’s right of access to basic water supply and basic sanitation. It requires water services institutions to take reasonable measures to realise these rights. Section 11 further places duties on water services authorities to progressively ensure access to water services for consumers and potential consumers in their areas.

These responsibilities are important when a municipal water supply becomes contaminated.

Depending on the circumstances, the responsible authority may need to investigate the problem, identify the source of contamination, take corrective action and communicate relevant health risks to affected consumers.

A failure to respond appropriately may raise questions about whether the authority has fulfilled its legal obligations.

2. Government departments and regulatory authorities

The Department of Water and Sanitation has national responsibilities relating to water resource management, regulation and oversight.

The Water Services Act provides for the monitoring of water services institutions and intervention where authorities fail to perform their functions effectively. The National Water Act also provides mechanisms for addressing pollution and protecting water resources.

The Department of Health also has an important role in public health protection, including the monitoring of health risks associated with unsafe water.

Where contamination affects a community, the relevant authorities may need to work together to investigate the problem and protect affected residents.

3. Businesses and other parties responsible for pollution

Contaminated water does not always originate from municipal infrastructure. Industrial activities, waste disposal, sewage leaks, mining operations and other activities may contribute to water pollution.

Section 19 of the National Water Act 36 of 1998 places a duty on owners of land, persons in control of land, and those who occupy or use land to take reasonable measures to prevent pollution of water resources where activities or conditions on that land cause, have caused or are likely to cause pollution.

These measures may include stopping the activity causing pollution, containing pollutants, removing the source of contamination and remedying its effects.

A private business or other responsible party may therefore face legal consequences where its activities cause water pollution and the relevant legal requirements for liability are established.

What standards apply to drinking water in South Africa?

Water supplied for drinking must meet the applicable national drinking water quality requirements.

The Water Services Act provides for compulsory national standards relating to water services and water quality. The revised Compulsory National Water and Sanitation Services Standards were published in Government Gazette 52814 on 6 June 2025 and commenced on 16 April 2025, replacing the previous 2001 standards.

The standards include requirements relating to drinking water quality and responses to water quality failures.

The 2025 incident management protocol recognises that drinking water quality failures can pose risks to public health. It emphasises the importance of documenting incidents, responding to failures and communicating relevant information to affected communities.

This is particularly important where children attend schools or live in communities affected by contaminated water. Residents need accurate information about the nature of the risk, precautions to take and steps being taken to restore a safe supply.

Can families claim compensation when children become ill?

In certain circumstances, families may have legal grounds to pursue a claim for damages if a child suffers harm because of contaminated water.

However, the fact that a child became ill after using a particular water source does not automatically establish legal liability. The circumstances must be investigated and the necessary legal elements must be proved.

A delictual claim generally requires evidence of:

* Wrongfulness: The conduct or failure to act must be legally wrongful.

* Negligence or fault: The responsible party must have acted negligently or with the required form of fault.

* Causation: There must be a legally sufficient connection between the conduct and the harm suffered.

* Damage: The child or claimant must have suffered legally recognised harm or loss.

For example, if a responsible authority receives repeated complaints about contaminated water but fails to take reasonable steps to investigate or address a known risk, its conduct may raise questions of negligence and legal responsibility.

A claim would still require evidence establishing the relevant duties, the failure to meet those duties, the child’s injury and the connection between the contamination and the harm.

Depending on the circumstances, damages may include reasonable medical expenses and other legally recognised losses. Where a child suffers long-term injury, the potential consequences may require further medical and legal assessment.

What evidence should affected families keep?

Evidence can be important when reporting contaminated water or considering possible legal action.

Families and community members should consider keeping:

1. Medical records: Keep hospital records, medical reports, prescriptions and other documents relating to a child’s illness or treatment.

2. Water test results: Where possible, obtain water quality testing from an appropriately qualified laboratory. Record where and when the sample was collected.

3. Photographs and videos: Document visible signs of contamination, damaged infrastructure, sewage leaks or affected water sources.

4. Complaint records: Keep copies of emails, reference numbers, letters and messages sent to the municipality or relevant authorities.

5. Witness information: Record the details of people who can confirm the conditions in the affected area or the complaints that were made.

6. Information about exposure: Make a record of when the child may have been exposed, the source of the water and when symptoms developed. Medical professionals should assess whether the illness is consistent with the suspected exposure.

Families should avoid handling potentially hazardous water unnecessarily or attempting to collect samples without appropriate guidance.

What can communities do when their water is contaminated?

Communities should not have to wait until people become seriously ill before water quality concerns are addressed.

Where residents suspect that their water is contaminated, they can take practical steps to raise the issue and protect their families.

* Report the problem to the relevant municipality or water services provider.

* Request an investigation and appropriate water quality testing.

* Keep written records of complaints and responses.

* Follow official public health warnings and instructions.

* Avoid drinking or preparing food with water that authorities have identified as unsafe.

* Seek medical attention if a child develops symptoms after possible exposure.

* Escalate unresolved concerns to the relevant provincial or national water and health authorities.

Where a serious risk persists and authorities fail to take appropriate action, affected residents may need legal assistance to understand the available remedies.

The importance of protecting vulnerable communities

Contaminated water can affect anyone, but its impact is often more difficult for vulnerable communities to manage.

Households with limited financial resources may struggle to purchase bottled water or travel to alternative water sources. Schools and childcare facilities may also lack the resources to secure an alternative supply for children.

The legal responsibility to provide access to water and prevent pollution must therefore be considered alongside the practical realities faced by affected communities.

Protecting children requires more than responding after an illness has occurred. It requires reasonable prevention, proper monitoring, timely communication and effective action when water quality problems are identified.

Conclusion

Clean and safe water is fundamental to public health, dignity and the protection of children’s rights. When water becomes contaminated, the consequences can affect entire families and communities, particularly those with limited access to alternative supplies.

South African law places responsibilities on water services authorities and provides mechanisms to address pollution caused by private and public activities. Where a failure to meet a legal duty causes harm, affected families may have grounds to seek legal remedies, depending on the evidence and circumstances.

Children should not have to bear the consequences of failures to protect essential water resources. Ensuring that communities have access to safe water is both a public health responsibility and an important part of protecting constitutional rights.
