Two Hawaii resorts and one nightclub must pay over $300,000 in fines to the Environmental Protection Agency for failing to close large-capacity cesspools, according to a press release from the federal agency.

The Travaasa Hotel Hana Resort in Hana, Maui, owes $187,500; Vacation Inns International on Oahu’s North Shore owes $40,000; and Shaka’s on the Big Island must pay $82,425.

In addition, the EPA has filed a civil complaint against Waimanalo property owner Keith Ward for two cesspools at Serg’s Mexican Kitchen restaurant.

“Cesspools serving resorts and restaurants can pollute the groundwater and nearshore waters where people swim,” said Jared Blumenfeld, EPA’s regional administrator for the Pacific Southwest in a statement. “EPA is committed to protecting Hawaii’s precious water resources by closing down all large capacity cesspools.”

Hawaii has more cesspools than any other state despite their negative environmental impacts. According ot the EPA, “disease-causing pathogens and harmful chemicals (from cesspools) can contaminate groundwater, streams and the ocean.”
