About This Data
This page aggregates environmental data from three EPA programs for Hawaii: the Toxic Release Inventory (TRI) for industrial chemical releases, the Safe Drinking Water Information System (SDWIS) for water quality, and the Superfund National Priorities List (NPL) for hazardous waste cleanup sites.
PlainEnviro presents this data without advocacy framing. Numbers reflect reported data and may not capture all environmental activity. For specific health or environmental concerns, contact your state environmental agency.
