Citizen science provides an opportunity for government agencies to expand data collection efforts in collaboration with community members to answer environmental and public health questions. Citizen science encompasses a wide variety of projects — from community science activities to public participation in scientific research. One of the best ways government agencies may contribute to these projects is to provide quality assurance guidance so the project data can be used for their intended purpose. Join this webinar to learn about successful state/federal agency-citizen science group collaborations and quality assurance resources to support these efforts.
