As well as having a Legionella risk assessment in place you may also have a need to carry out Legionella testing. There are a many types of Legionella bacterial strains, some are more common or harmful than others. Not all testing options cover the full range of bacteria or show how much bacteria is in your system. Identifying the type and levels of bacterial are important as they dictate the remedial, control and prevention measures required under the HSE's ACOP L8.
All water samples should be tested by a UKAS accredited laboratory as required by the HSE's ACOP L8. Not all testing products on the market are UKAS accredited. Same day testing options only give an indication of the presence of some Legionella bacterial strains. They do not give a bacterial count and are subject to uncontrolled test conditions.
Some service providers are also incorrectly using Dip Slides to test hot & cold water systems for the presence of Legionella bacteria. Dip slides should only be used to test for aerobic bacteria in water used in cooling systems and not in hot & cold water systems.
We recommend that testing be carried out as part of the initial risk assessment which allows the condition of the water to be "bench marked". The risk assessment will then identify if there is a need for further testing and recommend a testing frequency. At Water Wise we have a testing contract with one of the country’s biggest and leading UKAS accredited testing laboratories. Our normal turnaround time for test results is on average 14 days unless otherwise stated. Once testing is complete you are issued with a test certificate and any recommended actions that may be required. Our Legionella test certificates come with built-in document control stating how long the test certificate needs to be retained for.
