' Monitoring well design: In one well (MBRMW-1) the well screen slot size was <br /> increased from 0.01-inch to 0.02-inch in attempt to improve well yield for <br /> ' development and future sampling. Another well (MWM-9) was drilled to a <br /> depth of about 30 feet rather than the planned 22 feet depth. The deeper <br /> drilling depth was undertaken in an attempt to intercept additional coarse- <br /> grained sediment to improve potential well yield. <br /> Schedule: The approved workplan schedule indicated a submittal date for this <br /> ' Well Installation Report of May 27, 2005. <br /> Although not resulting in a deviation from the workplan, during the well <br /> t construction period two wells were installed as MWM-3. The first well was <br /> installed on 5/14/2005. Due to construction activities, the well was located near <br /> the northeast corner of Pond C, which was slightly north of its planned location. <br /> ' On July 1, 2005, the well (referred to as MWM-3) was destroyed and replaced by <br /> a new well (referred to as MWM-3r) constructed at its approved location adjacent <br /> to Pond C. In this Monitoring Well Installation Report (specifically, in Tables 1, 3, <br /> ' 4, 5 and 6, and Figure 2), and all future groundwater related reports the <br /> replacement well MWM-3r is and shall be referred to as MWM-3. Copies of the <br /> well log and destruction permit for the original MWM-3 are provided in Appendix <br /> ' F. <br /> 1 <br /> 1 <br /> 1 <br />
