Final Report prepared from the State of Hawaii Department of Health, the U.S. Environmental Protection Agency, and the U.S. Army Engineer Research and Development Center

Abstract

This project was completed by the University of Hawaii for the State of Hawaii Department of Health, the U.S. Environmental Protection Agency, and the U. S. Army Engineer Research and Development Center at Vicksburg, Mississippi. Its purpose has been to provide critical data about the possible existence of a hydraulic connection between the injection of treated wastewater effluent at the Lahaina Wastewater Reclamation Facility (LWRF), Maui County, Hawaii, and nearby coastal waters, confirm locations of emerging injected effluent discharge in these coastal waters, and determine a travel time from the LWRF injection wells to the coastal waters. The purpose of this Final Report is to detail final results of fluorescent dye tracer tests, associated groundwater modeling, and other results that have been made since the submission of the project's September 2012 Interim Report (Glenn et al., 2012). The purpose of this Executive Summary is to present an overview and synthesis of all principal project accomplishments, including both those presented in the Interim Report, and those of the new results presented in the Final Report Sections that follow here.
