Acid Sulphate Soils, Nata accredited

These are soils or sediments that when exposed to air can rapidly form sulphuric acid. This acid can leach into surrounding environments, possibly causing damage to concrete and steel structures such as foundations and swimming pools.

Envirolab Services is NATA accredited for the full SPOCAS suite (Suspension Peroxide Oxidation Combined Acidity & Sulfur) and Scr (Chromium Reducible Sulfur). This will provide results for both the ‘acid’ trail and the ‘sulfur’ trail allowing comparison of results to guideline values.

Turnaround Time

We can offer a standard 5 working day TAT for SPOCAS and Scr. Faster TAT’s are available, up to 3 working days, depending on the sample. Surcharges apply for fast TAT’s.

Sampling

A minimum of 200g should be collected in zip-lock bags to minimize contact with air. Large shells, wood, charcoal and stones should be removed in the field, but biological remnants such as roots should not be removed.

Samples should be kept cold in the field and should reach the lab within 24 hours of sampling. Where this is not possible samples should be either frozen or dried at 85°C and stored in zip lock bags.
