• d.1.7 Wells Associated With the WRN Proiiect <br />Well 4A-6V was completed and utilized for injection during June of 2000. Response <br />was immediate and positive at the recovery well for cavity 4A. There are three active <br />cavities capable of sustaining production to the plant, cavities 1A, 3A, and 4A. The <br />recovery well for cavity 4A does exhibit severe plugging across the downhole screen. <br />This well may be placed on injection, with well 4A-6V, becoming the recovery well for <br />cavity 4A. <br />Summary of WRN wells is as follows: <br />As of 1/1!2001 Seven active production wells <br />Six shut in production wells and two P&A wells <br />• Seventeen active monitoring wells <br />One shut in sonar access well <br />Two active subsidence/WL monitoring wells <br />One shut in core hole <br />One raw water supply well <br />Cavity 1 injection well 90-5 was plugged and abandoned in 2000. Refer to Table 4-1 <br />for names and descriptions of all existing wells. <br />4.1.8. Other Activities <br />The potientiometric levels monitored in the surrounding Dissolution Surface aquifer <br />monitoring wells provided continuous data, which was used to manage production/ <br />recovery operations at each of the active cavities. Throughout the year injection and <br />recovery rates were adjusted to reduce and/or maintain monitoring well levels to <br />• historic levels. <br />12 <br />
