    Description:
      Abstract: Measurements of water quality parameters were taken by Windward
Community College faculty and students at five sites in the
Enchanted Lakes, Kailua, Oahu, Hawaii coastal watershed during 
2003-2004.  Data provided as MS Excel spreadsheets.
      Purpose: Assess the water quality of the Enchanted Lakes watershed system

        Process_Description: Determination of Nitrite, Nitrate and PhosphateSummary of Method. Water samples are filtered and analyzed by ionchromatography (IC). Each analytical batch consists of a blank, 5 externalcalibration standards and a calibration check for every 8 samples. Themethod detection limits (MDL) are as follows: 0.1 mg/L for phosphate, and0.05 mg/L for nitrite and nitrate.Preparation of IC samples. Water samples are pre-filtered before analysis inthe Dionex ICS-90 ion chromatography system. Fresh water samples (5 mL) arefiltered through 0.20 mm IC Millex syringe filters (for freshwater samples)while saltwater samples are filtered through the Dionex Ag/H cartridges anddiluted 50:50 using deionized distilled water.Preparation of IC calibration standards. The following calibration standardsare prepared.(1) 0.1 mg/L of phosphate, 0.05 mg/L of nitrite and 0.05 mg/L nitrate(2) 0.2 mg/L phosphate and 0.1 mg/L nitrite and 0.1 mg/L nitrate(3) 1.0 mg/L phosphate and 0.5 mg/L nitrite and 0.5 mg/L nitrate(4) 2.0 mg/L phosphate and 1.0 mg/L nitrite and 1.0 mg/L nitrate(5) 10.0 mg/L phosphate and 5.0 mg/L nitrite and 5.0 mg/L nitrateCalibration. The calibration curve must consist of at least three datapoints. The response of each calibrator must be within 10%, otherwise, itdoes not meet method criteria and must be removed from the workingcalibration curve.Final data are summarized in Excel worksheets. The nitrite as N (mg/L) iscalculated by multiplying the nitrite (mg/L) with 0.304 (factor). Likewise,the nitrate as N (mg/L) content is calculated by multiplying the nitrate(mg/L) content with 0.226 (factor). The phosphate (mg/L) content isconverted to phosphorus (mg/L) by using the factor of 0.326.Determination of Total Nitrogen and Total PhosphorusSummary of Method. To analyze the total N and total P content, allphosphorus-and nitrogen-containing substances in the water sample are firstconverted to inorganic nitrates and phosphates by photo-oxidation. Afterphoto-oxidation, the samples are analyzed as described above.Photo-oxidation. Water samples (100 mL) added with 2 drops of 30% H2O2, arephoto-oxidized using Ace-Hanovia photooxidation apparatus (Department ofHealth State Laboratory) for four (4) hours to hydrolyze allphosphorus-containing substances into phosphates, and allnitrogen-containing substances into nitrates.
