1 <br />1 <br />' Sandstone at GF1 were steady for 1986 except for a rise in the last <br /> portion. Water levels gradually increased in well GF2 (see Figure <br /> <br /> A-14) in 1986 except for a decline in September. The water levels <br />' have risen at a faster rate in the KLM aquifer in this area in 1986 <br /> (see Figure A-15, well GF3). Water levels in well GF4 declined until <br />' March, 1986 but rose for the remainder of the year. <br />' Figure A-17 shows that the water level in backfill well GFS has <br />steadily risen since its installation. The average water level in <br />1 well GF6 for 1986 has declined slightly from the average value in 1985 <br />' (see Figure A-18). <br />Figures A-14 and A-15 present the water level changes for wells <br />GZ2 (U aquifer) and GZ3 (QR aquifer). Water levels steadily declined <br />' in well GZ2 until this well was destroyed by mining in mid-1986. <br />Water levels dropped rapidly in the QR aquifer in 1986 prior to well <br />GZ3 being destroyed. This data shows that mining had to be very close <br />t before drawdowns were observed in the QR aquifer in this area. <br />' Water level data for the three GBB wells is presented in Table <br /> A-6. Figures A-21, A-22, and A-23 present the water-level elevation <br />' plots for the three wells. Static water levels for well GBB1 have <br /> been above land surface for 1986. Water levels rose in 1986 in well <br />1 GBB2 until the November measurement. Water leve:Ls in Well GBB2 are <br />' not thought to be representative of heads in the aquifer due to the <br /> poor connection between the aquifer and well bore.
