8 - QAQC - quality is everything! (Part 2)

Quality Assurance and Quality Control, or QAQC, encompasses a range of controls that ensure accurate results in sampling. In this part 2 of the two-part series on QAQC, Optiro's Director of Geology Ian Glacken and Principal Paul Blackney discuss precision, contamination and best practice.

In this episode:

1:02 How do we measure precision and why is it important?
3:12 What are the properties of a duplicate for precision analysis?
3:50 Why do we need to take duplicates at various stages?
5:09 What are the types of information we need to present for duplicate samples and how do we measure precision?
6:46 Let's move on from precision and talk about contamination
10:11 Why do we need umpire laboratories and what are their roles in the process?
11:45 Are there differing views about when to use an umpire lab?
12:27 What are the benefits of QAQC and what are the risks of not having a robust programme?
14:20 Where can you learn more about QAQC?
