PFAS Testing Decisions: Expand In-House or Use Contract Labs?

Understand when it’s worth investing in PFAS instrumentation for drinking water analysis, and when outsourcing is the better fit

Written byWaters Corporation

PFAS testing in drinking water comes at a price: six-figure instruments, specialized staff, and contamination controls that don’t come standard. Depending on sample load and turnaround needs, outsourcing may offer better value—and fewer headaches.
