HONOLULU (AP) — The U.S. Environmental Protection Agency says a recent study confirms liquid flows through wells used by a Maui wastewater plant into the ocean via underwater springs close to shore.
University of Hawaii researchers conducted the study amid concerns coral reefs and the ocean are being harmed by treated wastewater pumped into the injection wells by the Lahaina plant.
EPA Pacific Southwest Region ground water office manager David Albright said Friday the study doesn't say the wells are the cause of coral reef decline. He says more research is needed on this issue.
The EPA said Friday researchers put a tracer substance into the injection wells near the Kaanapali coast. They later detected the tracer come out of underwater springs less than 30 yards from the shoreline.
