NPDES Training-Whole Effluent Toxicity Training and Videos

 The NPDES permitting program offers training courses, workshops, and webinars to explain the regulatory framework and technical considerations of the NPDES permit program. These courses are designed for permit writers, dischargers, EPA officials, and other interested parties.

These recorded presentations enable participants to review the material on demand in a self-paced environment.

Whole Effluent Toxicity Training

EPA headquarters' NPDES Whole Effluent Toxicity (WET) online training course covers the key elements of EPA’s NPDES WET permits program. These recorded web-based course modules cover most of the material presented during the live EPA NPDES WET courses provided to EPA regional offices and to the states.

The online NPDES WET modules are for persons implementing or permitted under the NPDES WET permits program. The modules familiarize viewers with EPA’s NPDES WET permits program and important WET technical concepts.

How to Navigate through Each Presentation:

Use the TABS on the left-hand side of the screen to access the online course menu to select: slide(s) from any of the modules, the audio transcript, and the acronym definition list available throughout all the modules. If you want to send a question click on the button at the top for Email EPA HQ’s WET Coordinator. The Resources button at the same location lets you access pdfs of several EPA NPDES WET documents and the WET analysis spreadsheet. The online course allows you to pause, advance to the next slide, or return to a previous slide similar to a DVD player.

The core modules in the online course focus on EPA’s freshwater acute and short-term chronic toxicity WET test methods. The course also includes information about EPA’s acute marine and short-term chronic estuarine and marine WET test methods used by states on the Atlantic Ocean and Gulf of Mexico; as well as short-term chronic WET test methods used by west coast states on the Pacific Ocean by clicking on a blue button when it appears. By clicking the blue button additional slides will appear with the relevant estuarine and marine WET test methods information. After viewing these additional slides, you will be automatically returned to where you were in the core NPDES WET course.

There is a quiz at the end of each module. You must pass this quiz in order to complete the module and be able to print a certificate of completion. A passing score of 80% is required. If you do not pass the quiz, you will be able to review the quiz or retry the quiz. You can review the module or any of the slides before repeating the quiz.
