The CCIL is pleased to release for public use two protocols for calculating uncertainty as developed by the uncertainty committee. The Chemistry or Type A Protocol was produced after peer review and input from CAEAL. The Microbiology Protocol is meant to be viewed as a discussion paper.
CCIL would like to acknowledge Mark Hugdahl of ALS Environmental and Garry Horsnell as being the authors of the Chemistry and Microbiology Protocols respectively.
Any comment or suggestion are encouraged and can be E-mailed to Rob Deverall (rob.deverall@alsglobal.com) at CCIL

The Uncertainty Disclaimer
Uncertainty estimate quoted in this report is based on routine lab samples and may not reflect the uncertainty in complex or unusual samples. Uncertainty estimates on a unique sample can only be obtained from replicate and/or spiked analysis of the actual sample itself.
