Description:
Abstract:
Measurements of water quality parameters were taken by Windward Community College faculty and students at eight sites in the Heeia Stream and adjacent Kaneohe Bay waters from May 2004 through March 2005. Parameters include Combined Nitrogen, Photo Oxidized Nitrate, Photo Oxidized Nitrite, Total Nitrogen, Total Phosphate. Data provided as MS Excel spreadsheets.
Purpose:
Assess the water quality of Heeia Stream and adjacent bay waters.

Process_Description:
Determination of Nitrite, Nitrate and Phosphate Summary of Method. Water samples are filtered and analyzed by ionchromatography (IC). Each analytical batch consists of a blank, 5 external calibration standards and a calibration check for every 8 samples. The method 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) are filtered through 0.20 mm IC Millex syringe filters (for freshwater samples) while saltwater samples are filtered through the Dionex Ag/H cartridges and diluted 50:50 using deionized distilled water. Preparation of IC calibration standards. The following calibration standards are 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 nitrate Calibration. The calibration curve must consist of at least three datapoints. The response of each calibrator must be within 10%, otherwise, it does not meet method criteria and must be removed from the working calibration curve.Final data are summarized in Excel worksheets. The nitrite as N (mg/L) is calculated 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 is converted to phosphorus (mg/L) by using the factor of 0.326. Determination of Total Nitrogen and Total Phosphorus Summary of Method. To analyze the total N and total P content, all phosphorus-and nitrogen-containing substances in the water sample are first converted to inorganic nitrates and phosphates by photo-oxidation. After photo-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 all phosphorus-containing substances into phosphates, and all nitrogen-containing substances into nitrates.
