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 has 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 <br />Well Number <br />Surface <br />Condition <br />Well Casing <br />Condition <br />Well <br />Redevelopment <br />Replace <br />Surface <br />Access <br />Replacement <br />Well <br />MW-1 Poor. Needs <br />to be cleaned, <br />and new <br />casing cap. <br />Assumed OK. <br />Need surface <br />well access <br />box repair. <br />Yes, casing <br />appears clogged <br />to the surface; <br />casing needs to <br />be cleared, <br />Surface access <br />should be <br />repaired with <br />an above <br />ground access <br />to prevent <br />burial. <br />No provided <br />well can be <br />cleared and <br />repaired. <br />MW-2 Appears OK.
