Environmental Testing for WaterLegionella Water Testing -Thermostatic Mixing Valves (TMVs)
Jaymak is able to provide water sampling from TMVs for certification of positive or negative results for Legionella. All samples are collected, sent and received within 24 hours at a NATA accredited lab for testing. Any samples received outside 24 hours will be tested but certificates will be marked "NOT TESTED WITHIN 24 HOURS OF SAMPLE" as per NATA guidelines. A negative report states "Less than 10 colony forming units/ml". A positive report may be from 10 up to 25,000 cfu/ml.

It may be reported as being Legionella pneumophila serogoup 1, or serogroup 2 to 15, or Legionella species (not pneumophila). Sometimes there is more than one serogroup present.
All reports with positive results of 10 or more require urgent decontamination.

Jaymak is also able to provide other potable water testing such as for Faecal (Thermotolerant ) & Total Coliforms, E.coli, Pseudomonas and Enterococci. Please contact Jaymak to discuss your specific requirements.
