40 <br />D <br />4 <br />ATTACHMENT B <br />SCOPE OF SERVICES <br />INDIAN RIVER COUNTY SOLID WASTE DISPOSAL DISTRICT <br />PREPARATION OF LANDFILL GROUNDWATER CONTOUR MAPS <br />Task 100 -Groundwater Contour Maps <br />Indian River County Solid Waste Disposal District (SWDD) is required by its Florida <br />Department of Environmental Protection (FDEP) operating permit to provide groundwater <br />elevation contours semi-annually. According to FDEP Permit No. S031-245825, Exhibit I, <br />Condition No. 23 SWDD must provide groundwater elevation contour map for each <br />monitored aquifer zone which is to be submitted semi-annually. <br />CDM will provide to Indian River County SWDD groundwater elevation contour maps for <br />the January, 1999 sampling event conducted at the landfill. When CDM receives the <br />individual monitor well groundwater depth readings from Envirometrics, Inc. the <br />groundwater elevation (in feet NGVD) will be calculated. Then they will be organized by <br />aquifer zone into shallow, intermediate and deep surficial aquifer readings and groundwater <br />contours developed on separate maps of the landfill for each aquifer. These contours will be <br />developed and reviewed by a registered professional engineer and certified maps provided to <br />Indian River County SWDD for submittal to the FDEP as required by permit. Any readings <br />which are not consistent with past observations will be referred back to Envirometrics for <br />confirmation. Only the January, 1999 event has been budgeted in this proposal. <br />SCHEDIII,F. <br />Groundwater contour maps for Task 100 will be provided to Indian River County SWDD <br />within three weeks of receiving the groundwater depth readings. <br />"0 A-1 <br />
