surface water parameter long list and monthly measurements of Flow, pH, conductivity, and <br />temperature. I <br />An initial spring and seep survey was performed in and around the Seneca II-W Mine area during <br />July, 1979. Locations of the spring sites that were surveyed are showrj in Exhibit 7-5. Historical and <br />descriptive information about springs is contained in the beginning of Appendix 7-7 of Tab 7, <br />Hydrologic Description. Eleven springs (sites enclosed with a rectangle in Exhibit 7-5) were <br />monitored for field parameters and sampled for water quality during June through October, 1983. <br />Water samples collected from these eleven sites were analyzed for most dissolved ions and some <br />trace elements. <br />Pre-October. 1991 Surface Water Monitoring Program. The pre-October, 1991 water monitoring <br />program is described in Appendix 15-2. The surface water monitoring program included surface <br />water and spring sites. Four surface water sites (SG5, SG7, FG1, and FG2) were operational prior to <br />1990. Flumes were installed at Sites FG4 and FG5 during 1990, and Site SG8 was also initiated in <br />1990. Site SG6 was replaced by NPDES Site 006 in September, 1989 following construction of Pond <br />006. Monitoring at the seven sites consisted of monthly (April through November) field <br />measurements (flow, pH, conductivity, and temperature) and triannual water sampling according to <br />the surface water long list of parameters. Continuous flow recorders were in operation at Sites FG1, <br />FG2, FG4, and FGS from April through November. <br />Implementation of the monitoring program initially required annual monitoring of Springs S-1, S-5, S- <br />23, S-41, and S-45 using field parameters and water samples analyzed for the surface water long list <br />of parameters (Appendix 15-2). The program was revised in May, 1987 to require monitoring at the <br />five springs on a semiannual frequency. Spring S-7 was added to the list of springs monitored at <br />Seneca II-W on a semiannual basis in May, 1987; however, permission to monitor this site was not <br />obtained until 1989. Spring Sites S-1, S-5, S-7, 5-23, S-41, and S-45 were monitored on a <br />semiannual basis (April-June and September-November) for field parameters (flow, pH, conductivity, <br />and temperature). Water quality samples were collected semiannually and analyzed according to the <br />surface water parameter list. The spring monitoring sites are shown in Exhibit 7-1. <br />The process of securing water rights for Pond 006 and a production well used for supplying water for <br />domestic and industrial uses, has resulted in the development and approval of a plan for water rights <br />augmentation. An integral part of this plan is the <br />C. J <br />8 ~ Revised 9/98 <br />
