    Nonpoint Source Pollution Educational Primers

    The following three educational primer modules are presentations intended to inform and educate a variety of stakeholders on the importance of nonpoint source (NPS) pollution and control within the Great Lakes basin. Each module is geared toward actions that may apply to different user groups and/or land uses.

    In addition to using these modules, the presenter is encouraged to provide local examples and contact information for audience members to seek additional information.
