Start date: Thursday, November 6, 2025
Start time: 1:00 PM EST
Duration: 60 minutes

Coliform and E. coli testing remain top priorities for many labs—and for good reason.

Last month, Shawn Dubois led a webinar covering tips, guidelines, and best practices for testing for coliforms and E. coli. Now, he’s back—this time joined by Valerie Neuhausser—to continue the conversation.

In this session, Shawn and Val will take a deeper look at coliform and E. coli testing, addressing common challenges and answering critical questions that arise in day-to-day lab work. Whether you're looking to refine your technique or troubleshoot issues, you'll gain practical insights to help you get the most out of testing with the Colilert, Colilert-18, Colisure, and Tecta tests.

Come with your questions. Shawn and Val will answer as many as time allows during the presentation.
