Special Focus on the Microbiological Testing of Water


Water, the origin of life, we wouldn't be alive without it. However, if not treated with the respect it deserves, water can harbour pathogens such as Legionella and Clostridium perfringens, which if ingested or inhaled can cause harm to the public and your business.

To prevent these catastrophic events from happening, water must go through various treatments e.g. UV, chemical and bactericidal, to remove potential pathogens from the water before it is released into the public domain.

However, problems can occur beyond an operator's control which may weaken the effect of these treatments, such as a purification system failure or system hacking, for example.

Therefore, water requires regular testing and is critical for any business or municipal authority to protect the public from infection.

This special focus on the 'Microbiological Testing of Water' equips you with the latest methods from suppliers of routine water testing kits. There's also a podcast and webinar for you to enjoy!

A recent amendment to the EU Drinking Water Directive now requires mandatory Legionella testing, another lockdown restriction is eased and stagnant water needs to be tested, the hits keep coming! How are you going to improve your laboratory's workflow and produce consistent, reliable and fast keep results? This rapidmicrobiology special focus on products for testing water delivers the latest in technology for water testing labs.

In this recently revised directive, PCR is identified as a complementary tool for Legionella testing, and Bio-Rad's iQ-Check Legionella Aquadien DNA extraction short protocols and Free DNA Removal Solution protocol has recently received AFNOR validation according to ISO TS 12869 and NF T90-471.

Pall GeneDisc Technologies provide complete solutions to water system network managers for real-time Legionella risk management and have provided reviews on some common methods for Legionella recovery. Also, BIOTECON and R-Biopharm both have RT-PCR kits that can rapidly detect & quantify low levels of viable Legionella pnuemophila plus screen for other Legionella spp.

How are you going to concentrate pathogens and viruses from water samples to match your sample size needed for your PCR, rapid or traditional culture methods? With just the push of a button on the Innovaprep concentrating pipette, large samples of up to 5L can be concentrated into 200 μL in just a few minutes. 

Looking for that supplier who wants to beat others on cost per test? Southern Group Laboratory (SGL) think they can, with their pre-poured microbiological media for water testing including those for Legionella spp. 

Think your microbiologists’ time could be better spent than on counting cells? With the MICA microcolony counters from DIAMIDEX, you can let artificial intelligence do the work and cut your incubation times by up to 80%!

Delivering counts within 10 minutes, without the need for growth, the Red One™ from Redberry uses a fully automated, touch-free membrane filtration system, suitable for volumes up to 100mL.

Cut out the hassle in confirming Clostridium perfringens colonies with CP ChromoSelect Agar from Merck KGAa/Millipore Sigma. This no-nonsense chromogenic agar can make light work of this elusive pathogen.

How reliable is your water testing method? Microbiologics makes life easier with their water testing reference strains and QC formats. Or maybe you're monitoring wastewater for SARS-CoV-2 and need peace of mind that your results are accurate? LGC AXIO Proficiency Testing can help you with its proficiency testing sample, compatible with CDC and WHO molecular assays.

If you're looking to change test kits altogether, look no further! A recent study by the Water Research Foundation (WRF) comparing test kits that detect SARS-CoV favoured the IDEXX test for consistency of detection. 

Plus, if you haven’t done so already, listen to Ray Petrisek in our podcast episode on Legionella. Ray was a principal investigator in the discovery of Legionella after the tragic mass infection event at the Legionnaires conference in Philadelphia back in 1976.
