� r <br /> Lysimeter Re-wetting: <br /> The lysimeters will only properly extract water from the surrounding soil into the porous cup if a <br /> vacuum is applied within the lysimeter.The lysimeter will naturally lose vacuum slowly over time, <br /> but vacuum loss will be escalated if the lysimeter goes dry.Due to the dry nature of the soils below <br /> the tailings facility,this is likely to happen.The lysimeters should,therefore,be re-wetted if vacuum <br /> loss becomes a common issue. The procedure for re-wetting the lysimeter is: <br /> (1) Un-clamp the white lysimeter re-wetting line,and green vacuum/pressure application <br /> line. <br /> (2) Using distilled water,place one end of a 1/4"plastic tube into the distilled water jug. <br /> (3) Create a siphon on the free end of the tubing while holding the jug several feet above <br /> the top of the metal stickup. <br /> (4) When water is flowing through the siphon,attach to white lysimeter re-wetting line. <br /> Allow to flow for about a minute, or until water is no longer flowing through the <br /> siphon. <br /> (5) Clamp the re-wetting line, and reapply the vacuum, as described above. <br /> (6) Wait 24 hours, and then extract and discard the excess water from re-wetting(see <br /> above). Re-apply vacuum after excess water has been discharged. <br /> B-2 <br />
