Why you need to test for excess copper in recreational water

Health Concerns

Excess copper in recreational water can pose significant health risks. Swimmers exposed to high copper levels may experience skin irritation, resulting in rashes, itching, and redness. This is particularly problematic for individuals with sensitive skin or pre-existing skin conditions. Additionally, high copper levels can cause eye irritation, leading to redness and discomfort, which can detract from the overall swimming experience.

Accidentally swallowing pool water containing excess copper can also lead to gastrointestinal issues such as stomach cramps, nausea, vomiting, and diarrhoea. These symptoms are especially concerning for children, who are more likely to ingest pool water while swimming. Ensuring that copper levels remain within safe limits helps protect swimmers from these adverse health effects.

Aesthetic and Maintenance Issues

Copper can cause noticeable aesthetic issues in swimming pools. One common problem is hair discolouration. Swimmers, particularly those with blonde or light-coloured hair, may find their hair turning a greenish tint after swimming in water with high copper content. While not harmful, this discolouration can be distressing and lead to complaints from pool users.

Excess copper can also result in staining on pool surfaces and fixtures. Blue or green stains on pool walls, floors, and equipment can make the pool appear unclean and poorly maintained. These stains are difficult to remove and can damage the facility’s reputation.

Equipment Damage and Maintenance Costs

High copper levels can lead to the corrosion of pool equipment, including pipes, heaters, and pumps. Corroded equipment not only requires frequent maintenance and replacement but also affects the efficiency of the pool’s filtration and heating systems. This can lead to increased operational costs and potential downtime for repairs, disrupting the use of the facility and inconveniencing swimmers.

Environmental Impact

Copper discharged from swimming pools can enter the environment, posing risks to aquatic ecosystems. Copper is toxic to many forms of aquatic life, and even low concentrations can harm fish and other organisms. By regularly testing and managing copper levels, pool operators can minimise environmental contamination and protect local water bodies.

Protect Swimmers and the Environment

Regular testing for excess copper in recreational water is crucial for several reasons. It helps protect swimmers from health issues such as skin and eye irritation and gastrointestinal distress. It also prevents aesthetic problems like hair discolouration and pool staining, as well as equipment damage and increased maintenance costs. Additionally, controlling copper levels reduces the risk of environmental contamination. By maintaining safe copper levels, pool operators can ensure a safe, enjoyable, and sustainable swimming environment for all users.
