Microplastics State Survey

The attached survey was disseminated through the ITRC state engagement network and took place from May 17 through June 21, 2021. The team received 43 individual responses to the survey, which included multiple responses from some states. Survey feedback indicated that while most states were not actively working on MP in the environment, some states have active programs. Nearly all respondents stated that additional information on MP would be helpful to their programs.
