7 <br />59 <br />• ~ 2.1x106ft2. Downward flow from this body of alluvium is estimated to be <br />441 ft3/d or only 2.3 gpm. This small water loss from the stream-alluvial <br />aquifer system will have no impact on water levels or water quality in <br />either the alluvium or the stream. <br />MONITORING PROGRAM <br />The future monitoring program will be centered around the determination <br />of water quality in the stream and the adjacent alluvium. Alluvial wells <br />AL 1-1, AL 2-l, AL 3-3, and AL 4-2 will be sampled quarterly. The water <br />~ quality data given in Appendix E, Table E1 constitute the results for the <br />first quarter of the monitoring program. Concentrations of dissolved iron <br />and manganese are expected to be relevant, but the steel casing is likely <br />- to cause the total concentrations of these two elements to 6e unrealistically <br />large. <br />• At the same times the alluvial wells are sampled, the stream adjacent <br />to each well will be sampled also. In addition, the stream will be gaged <br />by a current meter to determine the discharge. <br />• <br />
