SOIL AND WATER CHEMICAL TESTING SERVICES

Watertest is an independent chemical testing facility carrying out a comprehensive range of inorganic analyses on soils, waters, aggregates and biological materials. The lab is NATA accredited for the majority of testing, principally servicing clients from the environmental, manufacturing and civil engineering fields. Major items of equipment include ICP-OES, Ion Chromatograph, AAS, FIA, UV-Vis Spectrophotometer and Carbon/Nitrogen Analysers.

Tests not performed by Watertest such as organic and microbiological constituents are sub-contracted out to reputable NATA accredited laboratories on request.

TURNAROUND TIMES

Watertest generally has a 5-10 working days turnaround, depending on batch size and detection limits. Please specify if a faster turnaround is required (higher charges apply). The laboratory can comfortably handle up to 300 waters and/or 150 core samples per week for a normal range of inorganic and engineering parameters.

QUALITY CONTROL/QUALITY ASSURANCE (QA/QC)

The laboratory carries out extensive documented QA/QC procedures as set out in ANZECC Guidelines for Laboratory Testing of Environmental Soils and APHA "Standard Methods for the Examination of Water and Wastewater" (Latest Edition). Both standards set out definitions of bias, lower limits of detection (MDL), precision, accuracy, completeness and comparability; along with correct procedures for standard reagent preparations, instrument calibrations, data reduction validation and reporting, and corrective actions where required. The laboratory's QA/QC program has been fully approved by the National Association of Testing Authorities (NATA). Further details on any or all of these procedures can be supplied on request.
