Sensory testing for potable water quality and compliance

Eurofins Water Hygiene Testing in partnership with Eurofins Sensory and Consumer Research, provides a comprehensive range of sensory and appearance testing services.

Why sensory testing matters

Sensory and appearance testing forms a vital part of water quality monitoring, particularly for potable water where consumer perception and regulatory compliance are closely linked. Parameters such as taste, odour, apparent colour, clarity, and visible particulates help determine whether water is aesthetically acceptable, palatable, and free from signs of contamination or treatment issues. These analyses support public reassurance, system performance evaluation, and compliance with the Water Supply (Water Quality) Regulations.

Supporting consumer confidence and regulatory standards

Water should be free from unusual taste, objectionable odours, and visible discolouration or debris. Common issues include:

  • Musty or earthy odours from algal activity
  • Chlorinous or chemical tastes due to dosing imbalance
  • Discolouration from iron or sediment
  • Cloudiness caused by suspended solids or system disturbance

Regular sensory testing helps identify problems before they affect consumers or breach regulatory limits, supporting effective management of potable and private water supplies.

Testing and methods

Eurofins Water Hygiene Testing in partnership with Eurofins Sensory and Consumer Research, provides a comprehensive range of sensory and appearance testing services, including:

  • Taste and odour assessments (qualitative)
  • Apparent colour (visual comparison or colorimetry)
  • Clarity and turbidity, and visible particulate evaluation (qualitative inspection)

Testing is performed under controlled conditions by trained analysts, with results typically reported within five working days. Where quantitative or threshold testing is required, these analyses are conducted through approved subcontractors and Eurofins European competence centre partners for extended scope.
