Technical guidance

If your Phase 2 application has been approved for sampling, it is time to review the sampling technical guidance. We have simplified the EPA 3Ts guidance to ensure quick and easy sampling can be conducted for accurate results.

It is imperative to follow the methods within the guidance and training materials to ensure data quality objectives are met.
