B-2 also presents the TDS concentrations for QR well GP-5. TDS concentrations in this well were <br />steady in 2007. Water levels in this well have also demonstrated a suYUlar overall slight mcreasmg <br />trend over portions of their historical records which are likely natural. <br />Figure B-3 presents the TDS concentrations for three KLM aquifer wells. The data for <br />well GP-4 is presented in red square on Figure B-3 with steady values in 2007. The concentrations <br />have overall similar values for the last several years. TDS concentrations for two of the eastern <br />KLM wells, GP-2 and GP-8, are also shown on this figure with concentrations generally between <br />700 and 800 mg/1. Variable TDS concentrations that are overall steady have been observed in these <br />two wells for the last few years. <br />Figures B-4 and B-5 present the TDS concentrations versus time for the HI aquifer wells. <br />The TDS in HI aquifer well GF-4 had gradually increased in concentrations with time but have <br />been fairly steady for the last four years. The small changes are well within natural fluctuations in <br />this well but could be due to upgradient mining. TDS concentration m backfill well GF-5 is <br />slightly greater but is still well within the natural range for the HI aquifer. Significantly higher TDS <br />values have been observed in backfill well GF-7 with the concentrations in the last ten years being <br />between the lower levels prior to this period and the maximum historical values from this well. <br />One of the two values in 2007 for TDS was lower while the other value was very similar to recent <br />concentrations. TDS values in this backfill aquifer will likely fluctuate until they decline to a value <br />similar to the HI aquifer in this area. <br />Wells GMP-1 and GP-3 are two HI aquifer wells north of the A pit. Higher values of TDS <br />were observed in well GMP-1 during 2006 and 2007. This well is immediately downgraclient of <br />the reclaimed A pit and is likely showing fluctuations from the backfill aquifer. The previous TDS <br />values and fluctuations in well ('TMP-1 are similar to those in well GC-l, which had to be natural <br />Trapper Mining Company 3-2 <br />2007 Annual Report <br />
