Water & Environmental Microbiology


Modern water distribution systems in developed countries provide clean water to vast populations, so regular monitoring of water quality in terms of microbiological safety is highly regulated.

A failure in the system could lead to a significant public health risk, if contamination with a pathogenic organism were to enter such a widespread and essential commodity. Rather than looking for pathogens themselves, which should never be present at detectable levels in a well-controlled system, laboratories look at the overall hygienic status of the water, and specifically look for organisms which would indicate a failure of the treatment system. Such organisms should be absent or below the set limit for drinking water.


Drinking Water Proficiency Testing from Fapas

Fapas® Water & Environmental Chemistry Programme:

  • Drinking Water 
  • Bathing Water
  • Swimming pool/spa water
  • Environmental water (Legionalla)
  • Drinking water parasitology (Cryptosporidium and Giardia)

Tests are for routine indicator organisms in water as well as detection of pathogens including Salmonella spp., E. coli O157:H7, Campylobacter spp.


The Fapas® Water & Environmental Chemistry programme is accredited by UKAS to ISO/IEC 17043, certificate number 0009.

Participation in Fapas® is easy and can be tailored to suit your quality control programme. This can range from taking part in one of our scheduled tests, through to a company specific closed programme, customised to your needs (subject to minimum participation criteria). Orders can be placed via our network of agents, or via our online shop at
