The West Maui Preservation Association has been studying water quality problems associated with the Lahaina Wastewater Treatment Facility since its incorporation. WMPA focused on water quality issues around the nearshore waters of Hāʻenanui, Honokōwai. It supported community actions regarding EPA review of Safe Drinking Water Act regulations and eventually suing the County of Maui under the Clean Water Act regarding the illegal use of injection wells to discharge millions of gallons of effluent into the nearshore waters. The matter went up to the U.S. Supreme Court which agreed with WMPA’s main contention that the Clean Water Act applied to the County’s injection wells. It has conducted water quality sampling including pathogen sampling. It has sought remediation at the federal, state and county levels. Below are informational links related to the issue of West Maui’s injection wells.
