| Sewage Warning | Mokauea Island, Keehi Lagoon, OAHU Wastewater discharge | Other | In the investigation of a complaint, it has come to the attention of the Department of Health (DOH), Clean Water Branch (CWB), and Waste Water Branch (WWB) that illegal discharges of wastewater may be occurring at Mokauea Island, Keehi Lagoon, Oahu. Based on information gathered by the DOH-CWB-WWB, it appears that Mokauea Island has no sanitary sewage system and that the wastewater generated by the multiple local area residents and visitors is being discharged directly into the surrounding marine waters. The DOH-CWB believes that both the residents of the island as well as vessels docked at or near the island may be discharging untreated wastewater into Keehi Lagoon. The discharge of untreated wastewater is a violation of Hawaii Water Pollution rules and regulations. As a precaution, the public is advised to stay clear of waters around Mokauea Island until investigation is completed and wastewater issues has been resolved.
UPDATE 1/14/2008: Yesterday, a multi-agency investigation was conducted on Mokauea Island to determine what waste water systems exist on the island. Staff from the Department of Health, Clean Water and Waste Water Branch with staff from the Department of Land and Natural Resources, Division of Conservation and Resources Enforcement and Land Division conducted the investigation. Of the six houses on the island, only one of the houses had some type of waste treatment system. The other five houses were basically a direct discharge. As a result of the investigation, Warning signs will stay up until the sewage issue is resolved. The public is advised to stay clear of Mokauea Island in Keehi Lagoon. The DLNR is working with the DOH in correcting the sewage issues. |
