Hawaii SB471 mandates denitrification capacity for new or modified individual wastewater systems near shorelines or likely to pollute groundwater.

Hawaii SB471 aims to protect the state's nearshore waters by requiring newly installed or modified individual wastewater systems near shorelines or likely to pollute groundwater to include denitrification capacity. This requirement is based on a 2023 study that found coral reefs protected from land-based pollutants, especially wastewater pollutants, are better able to recover from ocean-warming events.
