3. Process and analyze annual data collection. The one-yeaz of data will be <br /> processed for water discharge (flow), nitrate and sediment concentrations, and nitrate and ' <br /> sediment loading for the watershed monitoring stations indicated in Table l. The entire study <br /> period dataset will be appended and analyzed to determine trends in flow and nitrates over time. <br /> 4. Prepare a final report. The final report will include summazies of the data <br /> collection for the year and comparative analysis of the da.ta from other years. The report shall <br /> contain discussions of the results of precipitation records, stream flow, nitrate and sediment <br /> concentrations, and nitrate and-sediment loading for the stations listed in table 1 during the study <br /> period. The report will also include an appendix containing the results of the azsenic and pH data <br /> collectia�. <br /> DELIVERABLES <br /> The main product to be delivered to the city will be the final report that summarizes the <br /> results of the study. A draft of this report (10 copies) will be delivered to the City of Decatur for <br /> their review 20 weeks after the end of the one-year data collection period, with the final report <br /> (approximately 25 copies)to be delivered 16 weeks later. <br /> Table 1.
