Water Sampling is often a crucial part of any Legionella Control Scheme, by measuring the effectiveness of the control measures. The ACoP L8 says "the risk from exposure to legionella should be prevented or controlled and that the precautions taken should be monitored to ensure that they remain effective".  Whilst routine Microbiological sampling is not always necessary as the water supplied to a building should be fit to drink. Where there is the potential for Micro-organisms to grow in areas of hot and cold water systems Microbiological sampling should be carried out:

  • Where drinking water (potable) is stored
  • Where systems treated with biocide and storage and distribution temperatures are lowered
  • Where control measures (correct temperatures) are not consistently achieved
  • Identification of potential hazards and associated risks
  • Where a Legionella outbreak is suspected
  • Where building occupants are deemed at risk, e.g. those who’s immune system is suppressed
  • Where the Legionella Risk Assessment findings recommend Microbiological sampling will aid monitoring

Total Viable Counts (TVC)

  • Basic test of water quality
  • Determines overall levels of contamination
  • Essential that TVC falls within recommended guidelines for the control of Legionella

Coliforms (Coliform & Faecal) & E-Coli

  • Coliform - Indicates potential contamination of water source
  • Coliform - Evaluates general quality of the water
  • Faecal Coliform - Indicates contamination from human / mammal waste product
  • E-Coli – short lived in water so is an indication of recent contamination
  • E-Coli – bacteria of the lower intestine. Rapidly detected on analysis and its detection indicates similar bacteria may be present

Pseudomonas Aeruginosa

  • Common bacterium easily colonises water systems and can produce a biofilm which affects taste and colour of water. This biofilm also produces a habitat and nutrient source for Legionella bacteria
