Ground Water <br />Water Levels. Water levels for all wells that are in the current <br />monitoring program are presented in Appendix C. Hydrographs of all <br />historic data for each well are presented prior to the water level <br />reports (for all data since 2000) for each respective well in the same <br />appendix. By presenting all historic data, trends related to seasonal <br />and annual variability are more clearly evident. Water level <br />measurements are taken with an electrical water level indicator, or in <br />the case of a few shallow alluvial wells, directly from a steel tape. <br />Site information, including sampling frequencies, is presented in Table <br />3, Summary of Ground Water Monitoring Wells. Ground water level <br />monitoring frequencies are listed in Appendix 15-3a of the Seneca II-W <br />PAP. <br />- Alluvium. The alluvial monitoring Wells WHAL6-1, 6-2, 6-3, 6-4, and <br />7-2 are located along Hubberson Gulch. All wells exhibit water level <br />seasonal variations typical for the alluvium, i.e., shallow after the <br />spring recharge, deepening towards the fall. Well WHAL10 is located <br />approximately one-half mile downstream of the NPDES 006 pond on a <br />tributary to Hubberson Gulch. It also exhibits seasonal variations <br />typical of previously mentioned monitoring wells. Water levels observed <br />this year for all of these wells fell within their historic ranges. <br /> <br />Well WDAL11, located immediately above the NPDES 005 Pond, is normally <br />dry. Well WSAL12 is located next to the lower Sage Creek flume site (SW- <br />S2W-FG4) Well WSAL13 is located on the northern tributary to Sage Creek <br />below the NPDES 009 Pond. This well is sometimes dry in the fall. Well <br />wSAL14 is located on the southern tributary to Sage Creek below the <br />NPDES 015 Pond. Most of these wells exhibit typical seasonal variations. <br />Water levels observed this year for most of these wells fell within <br />their historic ranges. <br />- Wadge Overburden. Most of the five current Wadge overburden wells <br />monitored normally exhibit seasonal variations typical of the overburden <br />aquifer (i.e., shallow in the spring or summer, deepening in the fall). <br />3 <br />
