Introduction

The Biological and Sediment Study on Marine Communities Near the City’s Ocean Sewer Outfalls

Annual biological and sediment studies (benthic organisms, coral reefs and fishes) determine the impact of ocean outfall discharges, if any, on the marine environment. Also, annual fish liver histopathology studies are used to determine the effects of treated wastewater discharge on fish caught near the outfall diffusers.

ABSTRACT:
This ongoing study provides biological monitoring services required to comply with the biological and sediment motoring requirements of the National Pollutant Discharge Elimination System Permits (NPDES) and the State of Hawai‘i Department of Land and Natural Resources Conservation District Use Permit requested by the City and County of Honolulu.

Annual biological and sediment studies (benthic organisms, coral reefs and fishes) determine the impact of the ocean outfall discharges, if any, on the marine environment. Annual fish liver histopathology studies are used to determine the effects of treated wastewater discharge on fish caught near the outfall diffusers.
