Analytical sampling is a critical part of environmental compliance - and it’s one area where small mistakes can quickly become expensive problems. 

With the upcoming release of the 2026 Alaska Multi-Sector General Permit (MSGP), and the new requirement for benchmark sampling for multiple sectors, many facilities will be performing analytical samples for the first time starting this year. In this episode of Tank Talk, we’re breaking down what that means in real-world practice - from the field to the lab. 

We’re joined by Justin Nelson of SGS USA, who walks us through the fundamentals of analytical sampling and helps demystify how laboratory data is generated, reviewed, and reported. 

Together, we cover: 

• The difference between qualitative vs. quantitative data 
• What testing methods are - and why they matter 
• How field sampling practices directly impact lab results 
• Common sampling mistakes (labeling, preservatives, volumes, chain of custody, and more) 
• What labs do once samples arrive and how testing standards are met 
• How to read lab data reports, including common notes and flags 

We also connect the dots between proper sample handling and better analytical results - fewer resamples, fewer corrective actions, and real cost savings. 

If you’re responsible for collecting samples, reviewing lab reports, or staying compliant under Alaska’s water permitting programs, this episode is a must-listen. 

Take your samples carefully - because the lab can handle a lot of things… but it still can’t analyze “oops.”
