Benchmark Performance Audit

The BenchMark Performance Audit was designed to take the place of the US EPA’s Water Pollution (WP) and Water Supply (WS) studies with significant improvements.

Order Benchmark PT samples as part of your laboratory’s certification process. The BenchMark Performance Audit may be used to demonstrate compliance with EPA, NELAC or state specific requirements for obtaining and maintaining laboratory accreditation. Although PT samples can be ordered at any time, each study is 45 days long, and a new study starts each month.
