• 11.4. Monitoring Well MW-4 (GPS N 37 56.808; W 121 19.919) <br /> This monitoring well is located in the southeastern corner of Parcel III. <br /> The condition of this monitoring well was initially unknown. There appeared to be <br /> a steel "stovepipe" which had been partially crushed and bent. The casing <br /> condition was unknown and it was unclear whether the bent stovepipe was <br /> associated with the well casing or not. If the stovepipe was associated with the <br /> well, it was unclear whether or not it had broken the well seal. <br /> Monitoring Wells MW-1, MW-3 displayed varying degrees of surface <br /> damage. Only Monitoring Well MW-2 appeared intact. Any potential damages to <br /> MW- 4 was unknown and required verification upon identifying the actual well <br /> cap. It is unclear when the wells were last cleaned and redeveloped. The <br /> following summary table present the anticipated repairs needed to return the <br /> wells to service based upon the surface observations. <br /> Table 1- Summary Table of Initial* Well Conditions, April 9, 2003 <br /> Monitoring Surface Well Casing Well Replace Replacement <br /> Well Number Condition Condition Redevelopment ASurface <br /> well <br /> ccess <br /> • MW-1 Poor.
