EPA has released new tools to help protect public health and local water bodies in communities that rely on lagoons for wastewater management. Lagoon wastewater treatment systems are typically used in communities that are smaller than 3,000 people and can lack the necessary financial and technical resources to comply with the Clean Water Act. EPA’s new tools are intended to help local decisionmakers effectively and efficiently protect public health and the environment, address compliance challenges, and improve asset-management planning.
