Nutrients And General Soil And Water Chemistry

ALS's range of accredited methods encompass the range of tests needed for routine monitoring of soils and waters for nutrients and general chemistry parameters. Used widely for state of the environment monitoring, as well as compliance with resource consents and trade waste conditions, these tests are routinely completed with fast turn-around times thanks to efficient testing processes that have been implemented in the laboratory.

Environmental monitoring

For a comprehensive list of tests please contact our customer support team – the following list is a summary only.

  • General Properties/Chemistry – pH, electrical conductivity, BOD, CBOD, COD, alkalinity, turbidity, solids, absorbance/transmittance, colour, ash (soils), particle size analysis, acid sulphate soil analysis
  • Organic Carbon – total, dissolved, non-purgeable
  • Gravimetric Analysis – various forms of solids in water by gravimetric analysis.
  • Nutrients – both dissolved and total forms of N and P
  • Cations and Anions - Anion/Cation balance
  • Chromium VI
  • Cyanide – both total and weak acid dissociable (WAD)
  • Silica – total dissolved
  • Leachate testing - TCLP and SPLP
