Legionella Sampling provides a more accurate insight to whether there is bacteria within the water systems at hand. Our legionella and hazardous materials team advise our clients on whether samples should be collected and provide further knowledge explaining the reasons for the requirement of sampling.
Certain circumstances where sampling may be needed include;
These are just a few reasons why sampling may be necessary. Our team are trained and competent to carry out legionella sampling in accordance with the Approved Code Of Practice L8 (2013), Health and Safety Guidance 274 Part 1 - 3 (2013/14) and British Standard 8580-1:2019. Water Quality - Risk Assessments For Legionella Control (click for overview document). Where sampling is carried out within Healthcare premises, we complete our work in accordance with Health Technical Memorandum 04-01.
In accordance with BS 7592:2022 - Sampling for legionella bacteria in water systems, trained and competent our Legionella Consultants will be able to discuss a sampling plan for the client and discuss in further detail the need for pre flush and post flush sampling. To briefly describe, pre flush sampling can give an indication of a localised issue with the water system whereas post flush sampling can determine a systematic issue with the water system.
Collection of Legionella Samples
Samples are collected in sample bottles containing sodium thiosulphate that neutralises any free chlorine in the system to provide a more accurate reading. All samples collected by our Legionella Surveyors will contain as much detail as possible such as location, temperature, time, pre or post flush and if it is a repeat sample. This information is very useful when interpreting the results from the laboratory.
Transportation and Analysis
We ensure all samples are escorted to a UKAS accredited laboratory in the right conditions, legionella samples should be stored at ambient temperature more specifically between 6°C- 20°C and aim to be at the laboratory for analysis within 48 hours in accordance with BS 7592. After the 10 day analysis period, once the results have been received, our team will interpret these at the clients request, for readings above 100cfu (colony forming unit) action is to be taken and this is where our legionella consultants expertise will apply.
In addition to legionella sampling, we provide microbiological sampling services such as pseudomonas, TVC (total viable count) at 22°C and 37°C, E.coli and coliforms. In accordance with the Water Supply (Water Quality) regulations 2016, E.coli and coliforms should have no detection as this deems the water not drinkable and further action will be required. For any further information please do not hesitate to contact our team.
