Water & Environmental Chemistry


The scheme satisfies the UK Drinking Water Inspectorate (DWI) requirements for the Water Supply (Water Quality) Regulation 2016: Regulation 16, Appendix 1 for both chemical and microbiological parameters.

As defined in law by standards for a wide range of substances, organisms and properties of water in regulations - drinking water must be ‘wholesome'. The standards are set to be protective of public health and the definition of wholesome reflects the importance of ensuring that water quality is acceptable to consumers. The legal standards in the UK are those which are set in Europe in the Drinking Water Directive 1998 together with national standards set to maintain the high quality of water already achieved. The standards are strict and include wide safety margins. They cover:

• chemicals such as nitrate and pesticides

• metals such as lead and copper

• the way water looks and how it tastes

Participation can be at a level that suits your business - from taking part in one of our scheduled tests,through to company specific closed tests.

Results from each proficiency test receive rigorous statistical analysis, ensuring you have clear feedback on your performance. Comprehensive reports provide information on analytical methods used by other participants. We can provide problem solving consultancy on your laboratory procedures if required.

Proficiency Testing from Fapas

Fapas Water & Environmental offers a comprehensive range of target analytes including:

  • Drinking Water Chemistry - for analysis of inorganics, metals and organics.
  • Drinking Water Chemical Contamination Emergency - aimed at testing the capabilities of a laboratory to analyse a completely unknown chemically contaminated drinking water sample on an emergency short-term rapid screening basis by identifying the toxic chemical contaminant(s) in a real drinking water sample. Also, a sample for analysis of gross alpha and gross beta radioactivity only is supplied.
  • Drinking Water Chemistry Taste & Odour Chemical Identification - aimed at testing the capabilities of a laboratory to analyse a chemically contaminated drinking water sample for completely unknown compound(s) that may produce a taste or odour.
  • Environmental Surface Water Chemistry - for analysis of inorganics and metals in clean river, reservoir or lake.
  • Environmental Waste Water Chemistry - for analysis of inorganics, metals and organics in water.
  • Environmental Soil Chemistry - Analysis of metals in soil.
  • Environmental High Salinity Water Chemistry - full volume simulated seawater samples made using NaCl with salinity of 3.5% for analysis of inorganics and metals.
