Similar pH values were observed for the HI aquifer at well GF -4 in 2014 to those observed <br />in previous years. Backfill well GF -5 had field pH values above 7.0 in 2014, while the field pH for <br />backfill well GF -7 was near neutral. The field pH values in backfill well GF -11 for 2014 were also <br />near neutral and similar to previous years. The field pH in well GF -6 (QR) was also above neutral in <br />2014. <br />Well GP -2 (KLM) water was slightly above neutral in 2014. The field pH values for well <br />GP -3 were higher than neutral from the HI aquifer and from well GP -4 above neutral for the KLM <br />aquifer. <br />Well GP -5 is completed in the QR aquifer and its field pH values are generally above 8. <br />The 2014 field pH values for HI aquifer well GP -7 were near neutral, while well GP -8 <br />(KLM) water had field pH values near 8.0 in 2014. The 3rd White Sandstone aquifer well GP -9 <br />field pH values are typically near neutral. <br />The alluvial (P -1) and 3rd White Sandstone (P -8) wells in Pyeatt Gulch all contain water <br />with field pH that is generally near neutral. The field pH values for well GNP -1 were near neutral <br />in 2014. The 2014 monitoring did not detect any indication of development of acidic water in the <br />Trapper Mine ground water. <br />3.4 NH3 AND NO3 <br />Concentrations of ammonia and nitrate are presented in Appendix B, starting on page B -220. <br />In general, concentrations of ammonia vary significantly from year to year. Wells GD -2, GD -3, <br />GF -4, GF -5, GF -6, GF -7, GF -11, GP -2, GP -3, GP -5, GP -9 and P -8 all contained NH3 concentrations <br />that are greater than 1.0 mg/l in 2014.
