• with mining in the west pod. All of the wells were monitored semiannually for water <br />levels, field parameters and water quality. None of these wells aze within the projected <br />angle-of--draw of mine workings. <br />Water levels from the five Roatcap Creek colluvial wells continued to show <br />typical seasonal variability with water levels elevated in the spring and lower at the end <br />of the year. No anomalies or impacts on water levels were observed in 1996 at these <br />wells. No anomalies or adverse impacts on water quality characteristics were observed at <br />any of these wells during 1996 as water quality analyzes yielded results compazable to <br />previous collected data. <br />STEVENS GULCFI COLLUVIUM GROUNDWATER MONITORING WELLS <br />Shallow groundwater monitoring wells' SM-1 and SM-9 (see Map No. 4-1) are in <br />the Stevens Gulch drainage. The wells are monitored for water quality parameters, water <br />levels, and field parameters to detect impacts associated with mining in the central pod. <br />Required monitoring for wells SM-1 and S>vl-9 was semiannually during 1996 for water <br />Levels and field parameters. Well SM-1 is next to areas mined in 1991 and 1992 but <br />• showed to apparent impacts in the field data collected during 1996. Well SM-9 was <br />undermined by Panel C during 1993 but showed no appazent impacts in the field data <br />collected during 1996. No anomalous water quality observations were apparent during <br />1996 at the Stevens Gulch shallow groundwater monitoring wells. <br />SURFACE WATER MONITORING STATIONS -PONDS <br />Eighteen ponds in the East Roatcap Creek drainage were monitored during 1996 <br />(refer to Table 5 and Map No. 4-1). Ponds were monitored quarterly for water levels and <br />field pazameters if they were discharging. Water quality samples were collected in the <br />spring. The ponds were not accessible during the first quarter monitoring because of the <br />lingering snowpack. The water quality samples were collected in May. No evidence of <br />mine impacts was noted. No retreat mining was conducted near any ponds during 1996 <br />in the East Roatcap Creek drainage. During 1994 retreat mining was done under Ponds <br />10-1, 10-2, ]0-3, 10-4 and 10-I 1. Advance mining occurred near ponds 88 and 14-2 <br />1996. The East Roatcap Creek ponds were physically intact throughout 1996 and showed <br />no subsidence effects. <br /> <br />Page -4- <br />
