ATTACHMENT B <br />SCOPE OF SERVICES <br />INDIAN RIVER COUNTY SOLID WASTE DISPOSAL DISTRICT <br />PREPARATION OF LANDFILL GROUNDWATER CONTOUR MAPS <br />PROJECT UNDERSTANDING <br />Task 100 - Groundwater Elevation Contour Maps <br />The Indian River County Solid Waste Disposal District (SWDD) is required by its Florida <br />Department of Environmental Protection (FDEP) operation permit to periodically prepare <br />and submit groundwater elevation contours to the Department. According to FDEP Permit <br />No. S031-245825, Exhibit I, Condition No. 23, the SWDD must prepare a groundwater <br />elevation contour map for each monitored aquifer zone, and submit these maps to the <br />Department semi-annually. <br />CDM will provide to Indian River County SWDD groundwater elevation contour maps for <br />the July 1999, January 2000, and July 2000 sampling events conducted at the landfill. When <br />CDM receives the landfill monitoring network groundwater depth readings from the County, <br />groundwater elevations (in feet NGVD) will be calculated. They will then be organized by <br />aquifer zone into shallow, intermediate, and deep surficial aquifer readings, and groundwater <br />elevation contours will be developed on separate maps for each aquifer unit. These contours <br />will be developed and reviewed by a registered professional engineer; certified maps will be <br />provided to Indian River County SWDD for submittal to the FDEP as required by permit. <br />Any readings which are not consistent with past observations will be noted. <br />SCHEDULE <br />Groundwater elevation contour maps for Task 100 will be provided to Indian River County <br />SWDD within three weeks of receiving the groundwater depth readings. <br />NA6706NGWC0NT-IU.T_99SEP.WPD B-1 <br />
