All samples are analysed on an as received basis and the results in rhis report pertain only to the sample submitted.
Liming rate only includes ANC when its effectiveness has been corroborated by simulative oxidation procedures such as incubation.
Measurement uncertainty data is available upon request. A liming safety factor of 1.5 has been applied.
Results apply to samples dried at 80-85oC. LOR denotes Limit of Reporting. N/R denotes not required.
This report supercedes any previous report(s) issued with this reference number. This document shall not be reproduced except in full.
Pacific Geotech accepts no responsibilty for the collection and transport of samples submitted by external parties.
