Microbiological Testing

Recreational water, such as swimming pools and spas, can present favourable conditions for the proliferation of infectious agents and bacteria. Regular testing is an essential part of any effective water treatment programme. As per the Pool Water Treatment Advisory Group Code of Practice, swimming pool water should undergo monthly microbiological testing by an accredited laboratory to monitor disinfection processes and help prevent the spread of harmful pathogens.   

Drinking water, also known as potable water, is generally supplied under agreed standards of quality in most developed countries.  

In the wild, environmental waters such as lakes, rivers and seas can be impacted by sewage pollution. Where these waters are used for recreational activities, such as swimming, diving, fishing or sailing, testing for the presence of bacteria can help you gauge the potential risk to health.  

Using a measure of total viable counts (TVCs), we can establish the level of microorganisms present in a given water sample. When such testing is integrated into an ongoing water-quality monitoring programme, it can provide a valuable indication of unexpected change to bacterial content levels. 

Key areas of risk covered by our microbiology tests: 

• Legionella 

The presence of this bacteria in water can cause Legionnaires’ disease, a potentially serious lung condition, as well as other illnesses. Envirochem’s Legionella analysis detects and quantifies the bacteria within potable, process and recreational water samples. Envirochem can supply self-sampling water-test kits, which can then be returned directly to our lab facilities. 

• Pseudomonas aeruginosa 

This pathogen can cause a wide range of infections, presenting a particular risk to anyone who is immunocompromised. Pseudomonas aeruginosa should not be present in drinking water and it is a common risk associated with recreational waters. 

• Coliform bacteria and E.coli 

Testing for these bacteria, which are commonly present in the intestines of animals and humans, can signal where water is contaminated by faecal matter. The ongoing management of this risk can provide evidence of the wider effectiveness of a water treatment and disinfection regime. 

Areas also covered by our microbiology testing: 

• Pseudomonas species   
• Faecal streptococci (enterococci)   
• Clostridia
