Measurements of water quality parameters were taken by Windward Community College faculty and students at seven sites along the Windward Oahu coast from March - June 2004. Parameters include salinity and enterococci concentration. Data provided as MS Excel spreadsheets.

Water samples were collected weekly over a period of four months at each of the seven beaches at the Windward area. Samples were collected in 100 mL sterile disposable bottles and transported (in ice cooler) to the Water Quality Laboratory at WCC Campus. Salinity measurements were taken using a Leica Refractometer. Enterococci most probable number (MPN) analysis was done using EPA approved IDEXX Enterolert method. Enterolert uses 4-methylumbelliferyl-Β-D-glucoside as the nutrient-indicator. This compound, when metabolized by enterococci present in the water sample, releases 4-methylumbelliferone, which exhibits blue fluorescence under the long-wavelength ultraviolet lamp. EPA standards for the yearly geometric mean (geomean) values for enterococci concentrations are set at 35 enterococci bacteria/100mL in marine waters. (51 FR 8012, March 7, 1986) The State of Hawaii, which has the most stringent standard of all the states, has set 7 enterococci/100mL. (Department of Health 1990).
