• <br />Spring S-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 EC <br />plot indicates an increasing trend. <br />Spring 5-47 was first discovered by SCC personal in 1989 and was <br />monitored first in June 1990. It is a developed spring existing <br />alongside the mine entrance haul road just to the west of the Seneca II- <br />W Meteorological Station. This spring became part of the required <br />monitoring program in 2000. Its EC plot indicates a decreasing trend. <br />Spring 5-48, a.k.a. the Flanders Spring, is located just upstream of the <br />009 Pond. This spring became part of the required monitoring program in <br />2000. The EC plot indicates a decreasing trend since 2001. <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 EC 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 EC plot indicates an increasing trend. <br />The hydrology monitoring program at the Seneca II-W Mine requires a <br />spoil spring survey every year after the spring snowpack runoff. Spoil <br />Spring 1 (WSSPGl, not to be confused with WSPG1) was discovered in 1998 <br />above the NPDES 005 pond (D pit area). It existed approximately 800 feet <br />southeast of Well GW-S2w-14W. Its EC plot indicates a stable trend. <br />• <br />19 <br />
