The requirements for the report, commonly referred to as the "biennial water quality <br />report", are described in Paragraph 62-701.510(9), FAC, and are included in the SWDD's Class <br />I landfill operation permit (No. S031-0128769-004). The regulations require that the report be <br />prepared, signed, and sealed by a professional geologist or professional engineer with <br />experience in hydrogeologic investigations. <br />Task 100 -- BIENNIAL WATER QUALITY SUMMARY REPORT (1999-2000) <br />Under this task, CDM will focus the evaluation on the data collected over the past two years <br />(1999 — 2000) for the landfill's ground water quality monitoring wells, which currently number <br />23, however, page 6 of Exhibit I attached to the operation permit states that water quality data <br />and water level measurements collected during the past four years shall be summarized and <br />interpreted. A map of the groundwater monitoring wells at the Indian River County landfill is <br />included as Figure 1. <br />The technical analysis required by FDEP includes tabular and graphical presentations of all <br />data, a trend analysis for detected parameters, correlation analysis between upgradient and <br />downgradient wells, correlation analysis between wells within well clusters, graphical water <br />contour maps and a summary of water quality violations. The report must also address the <br />adequacy and effectiveness of the existing water quality monitoring system. Paragraphs from <br />the facility's operation permit which define the report requirements are as follows: <br />24. A total depth measurement must be made on all wells biennially, beginning with the initial <br />monitoring. This measurement is to be reported as total apparent depth below; ground surface and <br />should be compared to the original total depth of the well. <br />25. A technical report shall be submitted to the Department every two years, and shall be updated at <br />the time of permit renewal. The report shall summarize and interpret the water quality data and <br />water level measurements collected during the past four years. The report shall contain, at a <br />minimum, the following: <br />a. Tabular and graphical displays of any data which shows that a monitoring parameter has <br />been detected, including hydrographs for all monitor wells. <br />b. Trend analyses of any monitoring parameters detected. <br />c. Comparisons among shallow, middle, and deep zone wells. <br />d. Comparison between upgradient and downgr.:2`' .—!! wells. <br />NA61Mr pM1i. WRM" -00i.113A. B-3 <br />
