i <br /> located in the location of former CPT soil borings, the construction of t h e <br /> monitoring wells will be predetermined based on the lithology from the <br />' previous CPT borings This will allow for the wells to be installed in a <br /> cost-effective manner It will also allow for the wells to be installed in a <br />' manner to minimize problems with flowing sands The CPT logs are <br /> presented in Appendix B In each former CPT boring location, a shallow <br /> monitoring well will be installed to approximately 19-feet bgs, a n <br />' intermediate well will be installed in the water-bearing zone located <br /> between 30 and 60-feet bgs, and a deeper monitoring well will be installed <br /> where a deeper water- Baring zone is present The wells will b e <br />' constructed to screen the following permeable water-bearing zones <br /> In the location of CPT-2 <br />' 9 to 19-feet bgs <br /> 35 to 50-feet bgs <br />' 100-115-feet bgs <br /> In the location of- <br />' 9 to 19-feet bgs <br /> 40 to 55-feet bgs <br /> 98 to 100-feet bgs <br /> In the location of CPT 12 <br />' 9 to 19-feet bgs <br /> 40 to 55-feet bgs <br /> 91 to 96-feet bgs <br /> In the location of -CPT-21 <br /> 9 to 19-feet bgs <br /> 1 33 to 45-feet bgs <br /> In h . location of CPT-25 <br /> 9 to 19-feet bgs <br /> 30 to 45-feet bgs <br /> Since CPT borings will have been drilled in these locations, the bottom of <br /> the augers will be plugged with a wooden plug and no soil samples will b e <br />' collected The reason for this procedure is that flowing (heaving) sands <br /> have been previously encountered at the site and drilling problems in <br /> these conditions can be greatly minimized if the bottom of hollow-stem <br />' augers is plugged until the total depth is reached Once the total depth o f <br /> the boring has been reached, the wooden plug will be knocked out from <br />' Frank's One Stop Workplan — September 2003 <br /> -14- <br />
