<br />See Figure 6 -12 for plots of three Perched aquifer wells, i.e. down-dip (89-3), up-dip (IRI- <br />1) and remote down-dip or maxi pad (IRI-5). <br />The A and B-Groove aquifers have shown localized water well pumpage effects (see <br />Figures 6-13 and 6-14). The effect on the A-Groove was as much as -30 feet immediately <br />down~iip, and -15 feet up-dip and ~ feet at remote down dip site early in the project. A <br />significant decrease was noted in 1998 at the down dip well with partial recovery noted in <br />December. In 1998 the B-Groove wells at the down-dip, maxi pad, and up{Jip sites <br />indicated increasing WL and therefore reduced effects of dewatering. The B-Groove WL <br />• generally recovered in 1998 with minor decrease in WL noted at all sites in mid-1998. The <br />B-Groove WL, south of the lease, fluctuated greatly. The B-Groove remained higher than <br />the A-Groove at all locations due to dewatering effects, which are greater on the A-Groove. <br />Mining effects on the Dissolution Surface were noted in late 1993 with the greatest increase <br />in water level at the down-dip monitoring site, less effect up-dip, and the least effect at the <br />remote site (see Figure 6-15). In 1998, mining was located near up-dip wells and effects <br />were more prominent at up-dip wells. In 1998 a downward trend was noted for down-dip, <br />up-dip and up-dip south of lease wells. At the remote maxi pad sites, the WL was stable <br />from 1994 - 1998. <br /> <br />75 <br />
