• The up-gradient wells were completed with water quality samplers in July, 1990 <br />and may show residual effects of prior completion problems from 1980-1990. <br />Water quality results indicate Dissolution Surface and B-Groove data similar to <br />wells immediately down-gradient. But the A-Groove and Perched aquifer <br />monitoring wells reflect a mixture of water from deeper aquifers. Table 6-3 <br />presents water quality data for the 1991 water year. No significant water quality <br />changes were noted during 1991 to indicate mining effects. <br />Pressure transducers were installed in November, 1990 with data acquisition unit <br />on line February, 1991 for water level monitoring. An obstruction in IRI-1, <br />probably sand and bentonite from water sampler completion, has limited water <br />level data collection. Water level data shown on Figure 6-5 indicate pumpage <br />effect on the A-Groove, with Figure 6-6 illustrating stabilized water levels. The <br />following table summarizes potentiometric water level data (from ground surface) <br />for monitoring wells up-dip of solution mining activity: <br />March Data Sept.

The Dissolution Surface has low volumes of water <br />and NaTec water quality sampling can be noted in the data. A slight water level <br />increase in B-Groove and decrease in Dissolution Surface may be a result of <br />• recompletion. Prior to completion, the open hole (IRI-1) at this site was adding <br />58 <br />
