Protect Water
Prevent Cancer

Our partners at the Iowa Environmental Council have created a series of training sessions that are useful tools to help us. As you know, election season is off and running and one of the most impactful things we can do is to let these candidates know how important these issues are to us by showing up to their events and town halls to find out what they propose to do to clean up our Waters. We want to help support you.
