DEP Training Modules

Training modules are intended to serve as student workbooks for use by approved training sponsors to develop pre-certification classroom training. However, many individuals use the modules as self-study guides for the certification exams. Please be aware that this is NOT the original intended purpose for these modules. If you have questions about which training module to study for which exam, call us at 717-787-0122 and ask to speak to someone in the Training Section or e-mail us at

Note to training providers: These modules consist of training 'content' only, and are not considered to be approved training courses worth credit for Pennsylvania water and wastewater operators unless an approved training sponsor submits a training course application to Pa. DEP. Please contact DEP at to obtain the instructor guides and PowerPoint delivery materials for the modules.
