Testing of PFAS in drinking water

General chemistry or base parameters include a number of tests that are used to indicate the water quality. These tests are not specific i.e. not targeting a specific contaminant.

Base parameters will be included in all drinking waters regulations and will have limits or ranges that are not to be exceeded.

When submitting a sample to an ALS laboratory you will have access to a wide range of base parameters, both regulated and unregulated.

Test methods in all ALS laboratories follow local legislation. Instrumentation used for testing is typically titration units or ion chromatography.

Analysis provided by ALS includes:
  • Turbidity
  • Odour
  • Colour
  • Conductivity
  • pH
  • Alkalinity
  • Fluoride
  • Chloride
  • Sulphate
