through the PVC pipe.  Once the well was emplaced within the PVC pipe, the pipe would be withdrawn.

At the time of the January meeting additional details needed to be worked out including the exact dimensions of the exclusion zone which isthe area to be evacuated - the extent of the zone is based on the size and type of anticipated UXO. For example,  a representative of Picatinny Arsenal had informally expressed the concern that if the exclusion zone should extend to Route 15 that the work might not be allowed to proceed because of the

 

 

 
Text Box: At the January 10, 2008 technical meeting Arcadis discussed an approach for installation of 10 monitoring wells at the site. The approach involves excavation of the upper several feet of native material (i.e., not the fill constituting the cap) in 6-inch lifts. Each layer would be scanned for unexploded ordinance (UXO). After the appropriate depth is cleared an 8-inch diameter pipe would be emplaced in the ground through the fill material and through the cleared zone. A drill rig would then be brought in to complete drilling Text Box: logistics involved in closing a major road such as Route 15. The Army, citing the unedited March 25, 2008 technical meeting minutes, has informed the RAB that a safety permit had been issued for the Area B well installations using avoidance only and that the wells were to be installed in April. The Army affirms that it is very pleased to present technical updates on any site at the Arsenal. Updates will be provided in future newsletters as they are made available to the RAB.
