<br />Dedicated Monitoring Wells Down-Gradient At Remote Site <br />Wells established to monitor down-gradient at the remote site or maxi-pad are: <br />Wells Aquifer <br />IRI-7 Dissolution <br />IRIS B-Groove <br />IRI-4 A-Groove <br />IRI-8 Perched <br />IRI-5 Perched <br />The remote down-gradient wells were recompleted in August and water quality sampler <br />installed in August -September, 1990. Initial water quality results indicated a mixture of <br />• water across all four aquifers which does not compare to other monitoring sites. The maxi- <br />pad had open hole completions and wells may have commingled aquifers for up to ten <br />years. Note the final well (IRI-5) on this site was recompleted July, 1991. <br />During recompletion, field water quality analysis indicated <1,000 conductivity for the <br />Perched aquifer and >20,000 conductivity for the Dissolution Surface aquifer, and that was <br />how sampling depth was selected. After a period of time, the aquifer data was expected to <br />reflect characteristics of aquifers at other monitoring locations. Tables 6-10, 6-11, 6-12, <br />and 6-13 summarize water quality data for period of record. No table was produced for <br />IRI-8 as lab analysis was reduced to annually. <br /> <br />63 <br />
