Accredited PDHs on PFAS, MS4, and WOTUS

Which providers are reliably accepted by state boards for PDHs on PFAS sampling QA/QC, MS4 permit updates, and the recent WOTUS shifts? I’m lining up courses for our 2025 stormwater program update and need certificates with IACET or state-board approval, clear learning objectives, and contact-hour breakdown to satisfy audit requirements… I can share our audit checklist if that helps benchmark.

Used StormwaterONE (IACET) for MS4; WEF PFAS QA/QC; WOTUS via PDHengineer; verify state pre-approval: https://www.stormwaterone.com

Building on @hannah_gar60, I’ve had the smoothest audits using APWA’s IACET-tagged MS4 courses and AWWA PFAS QA/QC webinars — certs include objectives and hour splits, and both were accepted by NY and FL for me (see AWWA: https://www.awwa.org/Events-Education/Distance-Learning). Tiny caveat: my WOTUS PDHs from ASCE were fine in TX but one reviewer asked for the instructor bio, so I attach it — want me to glance at your checklist?

ASCE/EWRI has solid MS4 and WOTUS updates, and Vector Solutions (RedVector) is broadly IACET; both will share a sample certificate with objectives and a time split if you ask — belt-and-suspenders, but it saves audits: https://mylearning.asce.org/. Small caveat: states like NY and FL want the ‘approved sponsor’ number printed, so confirm that before purchase — if you can share the target states, I can flag which require the sponsor number.

, state-by-state quirks make this messy — before you lock anything for the 2025 update, sanity-check providers against your strictest boards (NY/FL/NC) and the IACET directory: https://www.iacet.org/resources/accreditation-directory/; note some agency modules are solid but not IACET. When I vet a course, I ask for a sample certificate showing the learning objectives, a minute-by-minute agenda, the IACET ID, and whether they count 60- vs 50-minute hours, then I stash the instructor bio with the audit packet. If you share your checklist, I can spot gaps — do you require the pre-approval number on the certificate itself or is a provider lette.
