• <br />Springs. Spring data may be found after surface water data in Appendix <br />E. Data provided are a water quality report for the past two years, <br />historic flow measurements and remarks, a LOWESS plot of TDS, and a <br />historic listing of percent milliequivalents of major ions and TDS. <br />Baseline water quality statistics for springs downstream of mining (when <br />available) has been provided in Appendix E1. Springs with a flow less <br />than 5 gpm (0.011 cfs) are analyzed for field parameters only. In <br />Appendix E, all native springs have a WSPG prefix (e.g., Spring 5-45 = <br />WSPG45) while all spoil springs have a WSSPG prefix. <br />Spring 5-46 is a developed spring first monitoring during the 1979 <br />spring survey. This spring became part of the required monitoring <br />program in 2000. It is located immediately below the 005 Pond. The TDS <br />plot indicates an increasing trend. <br />Spring 5-47 was first discovered by SCC personal in 1989 <br />monitored first in June 1990. It is a developed spring <br />alongside the mine entrance haul road just to the west of the S <br />W Meteorological Station. This spring became part of the <br />monitoring program in 2000. Its TDS plot indicates a decreasing <br />and was <br />existing <br />aneca II- <br />required <br />trend. <br />Spring 5-50 is the discharge of the french drain that collects water <br />from the W-24 series monitor wells (located below Pond 16A) that failed <br />in 2003. This water was first sampled in September 2005. The W-24 wells <br />were finally abandoned in August 2007. Its TDS plot indicates an <br />increasing trend. <br />Spring S-7 in an alluvial clearwell located adjacent to Hubberson Gulch. <br />It serves as the non-potable water supply at the Smith ranch. Due to the <br />taste and possible coliform contamination of the spring, bottled water <br />is used for drinking. Sampling at this spring was discontinued in 1990, <br />but was reestablished in 1999 since it is downstream of mining at the <br />Seneca II-W South area. Its TDS plot indicates a recently decreasing <br />trend, with the peak value occurring in September 2006. 0 <br />18
