Once a two-hour period had elapsed,both holes were then backfilled and <br /> completed as described above.A schematic of the completed site 2 deep and shallow lysimeters are <br /> presented in Figures 2 and 3,respectively. The lysimeter cover was then locked. <br /> LWS has prepared a condensed operations manual with procedures outlined for taking samples, <br /> included herein as Appendix B. It should be noted that the pressure applied with the pump should <br /> not exceed 35 millibars, as the manufacturer suggests that a pressure of greater than 40 millibars <br /> could damage the lysimeter. <br /> If there are any questions regarding the installation procedures used for these lysimeter installations <br /> please do not hesitate to call the undersigned. <br /> Christopher M.D. F hn, PG, EI Bruce A.
