The Maternal and Child Environmental Health Collaborative Improvement and Innovation Network (MCEH CoIIN) is a platform designed to expedite improvements in priority areas through collaborative learning, quality improvement and innovation to decrease exposure to lead from major sources and/or increase access to systems of care. The National Environmental Health Association (NEHA) is one of the stakeholders participating in the CoIIN. NEHA will facilitate a panel with states within the CoIIN on innovative partnerships between Public and Environmental Health; reducing the number of children and mothers exposed to harmful lead. The panel will present challenges, growth and successes within their states.
