A leachate field will be installed in the Southern corner of Cell 2 to supply known quantities of liquid to the area over the pressure transducers. An aerial view of the leach field installation is shown in Figure 1. The leachate field will be fed via four individual pipes spaced as shown in Figure 2. Each pipe will be 200 feet in length with a perforated section of 120 feet. The end of the perforated section will be capped. The field will be placed approximately 8 feet above the surface of the leachate collection system as shown in Figure 3. This placement will ensure the pipes clear the contractor’s berm and allow the fabricator to cut off excess pipe and weld on a threaded fitting.

The leach field will be installed using the following steps:

1. A University of Central Florida team member will mark pipe installation locations along the Southern boundary of Cell 2 as shown in Figure 1. Assuming the waste will be filled from west to east, pipes will be installed one at a time at these marked locations when waste elevations of 8 feet are reached. The pipes will be pre-assembled down the slope of the contractor’s berm and will be ready for installation at that stage.
2. The pipes will be installed by dragging a pipe section into the waste mass such that it runs roughly parallel to the LCS laterals. The perforated (capped) end of the pipe will be in the waste mass and approximately 5 feet of the solid pipe will protrude out over the contractor’s berm at the location of the marker.
3. Ideally, University of Florida will be notified at the time of placement and they will survey the pipe location. If this is not possible, the landfill operator will note the vertical elevation of the waste and pipe at the marked locations.
4. One of the transducers located in the gray and green box will be installed adjacent to the pipe. The pipe installation marker will have the code for the appropriate transducer marked on it. Slack will be left in the cable to allow for settling and shifting.
5. Waste filling will continue until the waste elevation at the next marker reaches 8 feet. Steps 2 through 4 will then be repeated for the installation of this pipe.
6. This sequence of filling and installing will be repeated until all of the pipes have been installed.
7. The University of Central Florida team will be notified once all the pipes have been installed.
8. The pipe fabricator will be contacted to co-ordinate completion of the following tasks:

• Cut off all of the pipes approximately at the contractor’s berm,
• Weld a threaded fitting onto the end of each pipe.

It is important to note that clay should be avoided as daily cover in the waste mass between the LCS and the leachate field. The inclusion of clay will impair this experiment and complicate data analysis. It is most desirable that an alternative material be used in the 8 feet of waste over the transducers and in the first 5 feet of waste over the perforated pipe section.
