6 Ideas to Make a Flawless Transfer of Chain of Custody to the Lab

Imagine This… You have just finished a very large field program.  You must have collected nearly 100 samples, all different matrices (water, soil, sediment, product samples), and multiple analyses are needed.  You have COCs (chain of custody forms) filled out for everything, and you are driving over to the laboratory…

5 Outlooks for Environmental Forensics – Part Four: Communicate Science Clearly & With Certainty

This is part 4 of the blog series on the 5 outlooks of Environmental Forensics. Environmental forensics cases can be extremely complex.  They start with contaminants with large, awkward names that make most people uncomfortable.  We then talk about representative sampling, measurement uncertainty, concentrations in the part per million and…
