Water Sampling & Testing

Water testing may help identify areas where control has failed or needs to be improved where adverse samples are detected. We provide tailored sampling programmes for our clients according to their requirements. Sampling for legionella, Total Viable Counts, E.Coli and Total Coliforms are carried out in most buildings to monitor water quality and ensure corrective actions are taken if adverse test results are detected.

Legionella – Legionella bacteria can cause flu like symptoms in people, which it infects. Legionellosis (any illness caused by exposure to legionella) is normally contracted by inhaling legionella bacteria in tiny droplets of water contaminated with the bacteria deep into the lungs.  Infection with legionella bacteria can be fatal in approximately 12% of reported cases.  Aerosols can be produced from high-pressure taps, showers, water features with a fountain, cooling tower systems, spas, whirlpool baths, humidifiers and air washers.  Proper treatment, control and monitoring can control or prevent the risk of exposure to legionella.

E.Coli – occurs in the faeces of all mammals and is regarded as the primary indicator of faecal contamination.

Coliforms – are also used as an indicator for the presence of faecal contamination. There are, however, Coliforms that are present in soil and other environmental materials which can grow in water.

The E.Coli and Coliform tests are used as indicator bacteria as a means of assessing the potential presence of water borne pathogens. E.Coli is regarded as a the best biological indicator for drinking water and public health protection. Water borne pathogens include Campylobactor. E.Coli 0157, Salmonella and Shigella. These can cause gastrointestinal illnesses and can be potentially fatal.

TVCs – Total Viable Counts. These are counts of the general bacteria present in the water sample. An important benefit of determining colony counts is the data generated can indicate a significant change in numbers over a period of time which may highlight a deterioration in water quality.
