Contaminated water can cause serious illness, particularly where harmful bacteria, parasites or other contaminants enter drinking water supplies, recreational water facilities or workplace environments.

One of the best-known waterborne illnesses is cryptosporidiosis, an infection caused by the parasite Cryptosporidium. The illness can result in significant gastrointestinal symptoms and may have a particularly severe impact on young children, older adults and people with weakened immune systems.

Where illness occurs because water supplies, facilities or environments have not been properly maintained or monitored, it may be possible to bring a personal injury claim.

What is Cryptosporidium?

Cryptosporidium is a microscopic parasite that can cause an infection known as cryptosporidiosis.

People can become infected by swallowing contaminated water or coming into contact with contaminated environments.

Outbreaks have been linked to:

• Drinking water contamination
• Swimming pools and leisure facilities
• Agricultural environments
• Animal contact
• Contaminated food preparation areas

The infection can spread easily where hygiene and water management controls are inadequate.

How contaminated water illnesses occur

Illnesses linked to contaminated water can arise in a variety of settings.

Common causes include:

• Contaminated public or private water supplies
• Poorly maintained swimming pools or water attractions
• Inadequate water treatment systems
• Failures in environmental hygiene controls
• Agricultural runoff or animal contamination
• Failures to identify and respond to known contamination risks

In some situations, multiple people may become ill as part of the same contamination incident.

Symptoms of cryptosporidiosis and waterborne illness

Symptoms can vary depending on the nature of the contamination and the individual affected.

Common symptoms may include:

• Diarrhoea
• Stomach cramps
• Nausea
• Vomiting
• Fever
• Dehydration
• Fatigue

For some people, symptoms may last for several weeks and may require medical treatment or hospital care.

Responsibilities for water safety

Organisations responsible for managing water systems, facilities or environments are expected to take reasonable steps to minimise contamination risks.

Depending on the circumstances, this may include:

• Monitoring water quality
• Maintaining treatment and filtration systems
• Following hygiene and safety procedures
• Responding appropriately to contamination incidents
• Investigating and managing known risks

Where these responsibilities are not met and illness occurs, liability may arise.

The impact of contaminated water illness

Illness caused by contaminated water can affect many aspects of daily life.

This may include:

• Time away from work
• Medical treatment and recovery
• Ongoing digestive symptoms
• Financial loss due to absence from work
• Disruption to family and personal life

In more serious cases, vulnerable individuals may experience longer-term health consequences.

Claiming compensation for contaminated water illness

If illness was caused by contaminated water and reasonable steps were not taken to manage known risks, compensation may be available.

A claim may take account of:

• The severity of the illness
• Medical treatment received
• Loss of earnings
• Recovery time
• The impact on daily life
• Any ongoing symptoms or complications

Each claim depends on the circumstances of the contamination and the available evidence.

Time limits for contaminated water claims

Early investigation can be important, particularly where environmental evidence or outbreak information may be relevant.

Contaminated water and cryptosporidium claims – frequently asked questions

Can I claim compensation for cryptosporidiosis?

A claim may be possible where the illness was caused by contamination that could reasonably have been prevented or managed.

What if multiple people became ill from the same source?

In some cases, contamination incidents affect a number of individuals. Each claim will still be assessed on its own circumstances.

Does contaminated water always involve drinking water?

No. Illness can arise from a range of contaminated water sources, including swimming pools, recreational facilities and workplace environments.

How do I know whether my illness was caused by Cryptosporidium?

Medical records, testing and public health investigations may help establish the cause of an illness.

Can I claim if symptoms developed several days after exposure?

Some waterborne illnesses do not cause immediate symptoms. The timing and circumstances of exposure may be relevant when assessing a claim.
