Well WSAL12, located on. <br />I <br />Sage Creek adjacent to Surface Water Site SW-52-FG4 (WSSF3),- is <br />dow%is tream of all mine discharges on Sage~Creek. TDS values at this <br />well had been increasing since it was drilled in 1990, but have leveled <br />off since 1996. Well WSAL13 is located below NPDES 009 on the northern <br />Sage Creek tributary (this NPDES site, constructed in 1991, started <br />floiing for the first time eve= in 1996). This well displays an <br />increasing TDS trend. In October 2000, there was not enough water to <br />i <br />sample in this well. Well WSAL14 exists, on the southern Sage Creek - <br />tributary below NPDES 015 (constructed in August 1999, first flow <br />February, 2000). Monitoring was resumed at this well in May 1998 after <br />being discontinued in October 1995. It displays on increasing TDS <br />trend. <br />In I~the Probable Hydrologic Consequences section (PHC, Tab 17) of the <br />Seneca II-W PAP, predictions were made for the May-September average TDS <br />values at various alluvial wells.
