The fluid level data is used to adjust the injection/recovery flow rates as necessary to <br />maintain the Dissolution Surface aquifer potentiometric level at premining historical levels. <br />The following is raw water pumpage from we1190-1 with a 2005 average of 50.8 gpm compazed to <br />2004 of 44.2 gpm: <br /> Jan.

Sodium chloride from cavity 1A appeared to be affected <br />by recycled barren liquor through cavity 6H. Sodium chloride concentration is reduced only <br />by the dilution created during mining operation and quantities entrained in the product. <br />Sodium chloride levels are controlled within food grade limits by washing wet crystals, a <br />further limitation on sodium chloride exiting the system. <br />4.3.3 Monitoring Wells <br />EX-2, 4A-1 V, 93-2M, 90-2, DS-2, DS-3, and 1-3A are all equipped with pressure transducers <br />that have a continuous water level (WL) read out in the control room. In addition there are <br />thirteen wells equipped with pressure transducers, each record WL continuously, and data is <br />stored on a data acquisition unit and reported monthly. Water quality data is collected from <br />eighteen wells. Twenty wells are dedicated to monitoring; one is used as raw water well. <br />There are four subsidence/water level monitoring wells. <br />17- <br />
