| Project Name: | Controlling Water Contamination at the Source by Integrated Technologies, Kaiaka-Waialua Watersheds |
| ASO Log No.: | 04-198 |
| Start/End Date: | October 2003 to April 2006 |
| Federal Funds: | $153,800.00 |
| Matching Funds: | $154,200.00 |
| Contractor: | Dr. Ali Fares College of Tropical Agriculture and Human Resources Department of Natural Resources and Environmental Mngmnt 1910 East-West Road, Sherman Lab Room 101 Honolulu, HI 96822 Phone: (808) 956-8708 Fax: (808) 956-6539 |
| Background/ Overview: |
Kaiaka Bay and Waialua Bay, two adjacent water bodies on the North Shore of Oahu, have been classified by the Department of Health as water quality limited segments. Sediment loads from agricultural lands and effluent discharged from household cesspools are two of the major sources of pollution |
| Objectives/Goals: | To demonstrate and implement erosion control practices as an efficient tool to help manage erosion throughout Kaiaka-Waialua watershed. To reduce sediment and pollutant loads (phosphorous and nitrogen) into the surface and ground water sources, thereby improving water quality of the coastal area. To demonstrate the quantification of the improvement of water quality of the surface and subsurface soil waters. |
| Methods Employed: | • Plant two cover crops and compost to reduce surface
erosion and water quality degradation |
| Pollutants of Concern: | Phosphorous, nitrate, nitrite nitrogen, chlorophyll a exceeding maximum allowable levels, turbidity |
| Watershed: | Waialua, Kiikii, Poamoho, Kaukonahua, Paukaulia, Opaeula, Helemano, Anahulu, Kawailoa, Kawaiiki, Loko Ea and Keamanea Watersheds, island of Oahu |
| Size of Project: | 1 acre sampling site |
| Affected Water Bodies: | Kaiaka and Waialua Bays |
| Deliverables: | • Fact sheets • Journal articles • Web site with project information |
