The 4 main types of micro-organism that can be present in water are Coliforms, Cryptosporidium, Pseudomonas aeruginosa andEscherichia coli (E.coli).
Health, safety & environmental consultancy Assurity Consulting has for over 25 years “monitored the health of buildings” through independent workplace audits, especially covering indoor air and water quality. Assurity Consulting UKAS accredited laboratory, based in Horsham, West Sussex processes around 35,000 samples each year. Rebecca Jupp and her colleagues are regularly look at drinking water quality using general TVC’s (Total Viable Counts) at a range of dilutions, E.coli/coliform identification, Pseudomonas aeruginosa identification and Legionella identification from water samples.
When analysing samples for the TVC analysis, 1ml of the sample is placed into 2 separate Petri dishes, 15ml of Yeast extract agar (YEA) is added to each and left to set. They are then incubated at their relevant temperatures for a set period of time. After incubation, they are read using the Sorcerer system. Each Petri dish is placed in the Petri-viewer and dark-field illumination provides a high contrast image for the system to analyse. Special algorithms are used to detect, separate and count the number of colonies. The Sorcerer system is linked to the Assurity Consulting database, allowing all counts to be automatically entered against each particular sample. Typically, up to 400 plates are counted per day.
The system has significantly reduced the time spent in reading these plates, and by linking to the company database, the risk of errors has also been reduced. Furthermore, certain bacteria such as aerobic spore bearing types, which have irregularly shaped colonies can be excluded from the counts using the image editor function. Assurity Consulting has a UKAS accredited laboratory, and any new procedures/equipment must be of a high standard. The accuracy of the Sorcerer colony counter ensures that there is no ‘drift’ during use and its audit trail facilities guarantee that it conforms to UKAS standards.

They provide professional, qualified advice on a broad range of Environmental Auditing, Risk Assessment, Health & Safety, Training needs and specialist consultancy.
