Parameters to be <br />Appendix 15 -3a, Table 3 <br />Parameters to be sampled are conductivity (umhos /cm), pH <br />analyzed in ground water <br />of CDRMS mining permit <br />(units), temperature (C), dissolved iron (mg /1), dissolved <br />samples <br />C- 1982 -057 <br />manganese (mg /1), dissolved fluoride (mg /1), dissolved nitrate <br />(mg /1), dissolved nitrite (mg /1), dissolved selenium (ug /1), <br />dissolved sulfate (mg /1), total suspended solids (mg /1), and <br />total dissolved solids (mg /1). All parameters were met. <br />18. Basic Standards for <br />CWQCC regulations 41.4 <br />The Seneca II -W Mine did not generate significant amount of <br />Ground Water <br />and 41.5 <br />Ieachates in 2013. Four groundwater wells exceeded the <br />manganese standard (0.2 mg /1) in 2013. As mentioned in the <br />above item number 8 above, in soils with a high pH a <br />standard of 10 mg /I would be more appropriate than the .2 <br />mg /1. In 2013 none the Seneca II -W wells displayed a value <br />higher than 1.57 mg /1. Three groundwater wells excceded <br />the iron standard (5.0 mg /1) in 2013, including well DCAL -02. <br />The pH standard (6.5 — 8.5) was excceded at one site. <br />
