vandalism to the monitoring equipment. The system will be powered by a solar panel, <br /> and one of the units will be equipped with a meteorological weather station(rainfall, <br /> barometric pressure, evapotranspiration, solar radiation, etc). Both multiplexers will be <br /> accessible via remote telemetry for convenience in downloading and data analysis. <br /> Task la—Installation of Moisture Monitoring Equipment <br /> Installation of the TDR water content reflectometers (WCR's—Appendix A) is by <br /> horizontal placement. A backhoe and manual tamper(compactor) will be required for <br /> placement, and it is assumed the client will provide this equipment. The WCR placement <br /> is off-set so that no probes overlie each other. Once the probes are installed and cover soil <br /> has been placed and compacted over the probes, the wires are placed in protective PVC <br /> conduit and wired to the datalogger(multiplexer). It is assumed that 2 moisture stacks <br /> will be monitored as a part of the FL alternative final cover demonstration project. The <br /> proposed locations of these stacks are presented on Figure 1 and the proposed vertical <br /> distribution of the WCR's is presented on Figure 2. <br /> Task lb—Calibration and Annual Maintenance of Moisture Monitoring Equipment <br /> Calibration of the WCR probes is conducted by careful monitoring of the system, and <br /> comparative moisture sampling from samples collected within the monitoring system. <br /> Collection of field samples for laboratory testing are compared to actual system readings <br /> at depth until the resolution is within a specified range(usually±5%volumetric water <br /> content). In addition, an annual maintenance check of all system components will be <br /> conducted to verify full system functionality and to verify no vandalism has occurred to <br /> the units. <br /> Task 2—Flux Monitoring <br /> In addition to the WCR probes, two drain gauges (manufactured by Decagon—Appendix <br /> B) will be installed at each stack location to monitor physical water movement through <br /> the final cover soils. These too, will be wired to the datalogger for remote access to the <br /> data. <br /> Task 3—Installation and Monitoring via Remote Telemetry System <br /> This task includes the installation of a remote telemetry system that will be installed to <br /> allow for fast and convenient access to the units at any moment in time. Once the system <br /> is in full working order, data download for the probes will be accessible from any <br /> computer that has the appropriate program installed. Data will be retrieved twice <br /> monthly and a data file will be created for every download event from each of the <br /> multiplexer units. <br /> C:\2005-0082\workplan.DOC\07/11/05 —3— <br /> GeoLogic Associates <br />
