Monitoring and Extraction Wells. There are four (4) groundwater extraction and 23 monitoring wells known to exist in the vicinity of Buildings 104, 107, 108, 109, 113, 476, 503, 525, 526, 529, 543, 554, 556, 596, and 944 (see Figure 4).

Monitoring and Extraction Wells. There are 4-groundwater extraction and 23 groundwater monitoring wells known to exist on the site. (See Figure 4). Table 6 in Section 5.1 entitled “Monitoring and Extraction Wells” provides a list of these wells. It is believed that all of the wells are completed at surface grade. Wells of this type are often overlooked during construction activities and can be inadvertently damaged or destroyed unless proper demarcation is performed prior to construction activities. The Navy and MEW companies will develop their own requirements related to wellhead protection procedures and requirements. If no other options are available and a well must be destroyed, then the well owner must be notified in the planning stage of the proposed project(s). Additionally, if a well is damaged or destroyed during demolition/construction activities, the well owner must be notified as soon as possible. The Navy, MEW companies, the EPA, and the RWQCB may require that a replacement well be installed if a well is destroyed or damaged beyond repair. The Navy and MEW companies will develop their own requirements for the developers to implement related to the replacement of destroyed wells (if required). Before any well is altered or destroyed, the well owner must be notified and their approval must be granted. A point of contact for the Navy and the MEW companies will be identified. The EPA and RWQCB must be notified before a well is destroyed. Additionally, the Ames Environmental Services Office must also be notified before a well is destroyed. A Well Destruction Permit from the Santa Clara Valley Water District (SCVWD) is required before a well is destroyed. The, permit must be submitted to the SCVWD at least 10 days prior to well destruction. A minimum 24-hour notice must be given to SCVWD Well Inspection Department prior to destroying the well. A District Inspector must be on site to witness the destruction procedure. Contractors performing the work must be C-57 licensed. The driller/consultant must have a current copy of their Worker’s Compensation Insurance on file with the SCVWD. A Well Installation Permit from the SCVWD is required before a well is installed. The permit must be submitted to the SCVWD at least 10 days prior to well installation. A minimum 24-hour notice must be given to SCVWD Well Inspection Department prior to installing the annular seal. A District Inspector must be onsite to oversee the installation procedure. Contractors performing the work must be C-57 licen...
