<br />communication with bedrock material above the Wadge Coal Seam while at TR-3 <br />and TR-4 the alluvium is in communication with bedrock material below the <br />Wadge Coal Seam. Even alluvial wells TR-3 and TR-4 do not exhibit the trend <br />established in the surface waters. During baseline studies and up through <br />late 1982, TR-4 generally showed lower concentrations of all detectable <br />parameters than TR-3. This is consistent with the trend noticed in Trout Creek <br />given the relative locations of the two wells. However, during the period <br />from 1983 through 1986, TR-3 exhibited lower concentrations, while in 1987 the <br />two wells showed very similar concentrations with TR-4 generally showing lower <br />concentrations late in the year. The reversal in parameter concentrations <br />between TR-3 and TR-4 suggests that the behavior of the alluvial water is not <br />consistent with that noticed in the surface waters. <br />The above relationships do suggest with regard to fluvial dynamics that <br />water in the alluvium does exhibit some amount of parallel flow to that of the <br />"free" water in the creek for some distance downstream. Therefore, the only <br />• generalization that can comfortably be made on the interrelationship between <br />alluvial water quality and surface flow in the adjoining creek is that when <br />the origin of water in the alluvium at a given location is from a source other <br />than the creek itself, an influence may be expressed on both alluvial water <br />and surface water downstream. This would be true, particularly, during <br />periods of low surface flow. <br />• <br />
