Water Testing

water pollutionWe are able to undertake a wide range of tests on groundwater, effluent, catchment and waste waters in our NATA-accredited laboratories (NATA 198, 2474 and 1388). For our:

  • organic tests we use GC-ECD/NPD/FID, GC-MS, HR-GC-MS, GC-MS/MS, HPLC-PDA/FLD, UHPLC-MS/MS and UHPLC-QTOF/MS
  • nutrient analysis, physical and inorganic tests we use 1D/2D-ion chromatography, flow injection analyser, UV/Vis spectrophotometer, a discrete analyser and ICP-AES/ICP-MS

Our limits of reporting are usually five to ten times higher than the limits of detection.

Our standard turnaround time (depending on batch size) is 5 to 7 working days, 10 working days for microbiological tests and 20 working days for ultra-trace dioxin tests (if you require a shorter turnaround time, contact us before you despatch the sample – premiums apply).
