KAANAPALI, MAUI (HawaiiNewsNow) - Federal officials are looking into whether wastewater is polluting coastal waters along the Kaanapali coast of Maui.
The Environmental Protection Agency (EPA), U.S. Army Corps of Engineers, Hawaii Department of Health and the University of Hawaii are working together to measure how long it takes for wastewater from the Lahaina sewage treatment facility to flow to the ocean.
UH scientists will inject a tracer dye into the facility's underground injection wells and monitor areas where fresh water seeps into the ocean for signs of the dye.
Staff from UH and the Department of Health will take periodic ocean water samples at identified ground water discharge points to assess water quality.
"The tracer study will help us pinpoint wastewater movement from the Lahaina injection wells," said Alexis Strauss, Director of the Water Division for the EPA's Pacific Southwest Region. "The goal is to evaluate the potential impact of the facility's discharge on the coastal waters."
Reports on the results of the tracer dye test and water quality monitoring studies will be made available to the public later this year.
