WATER QUALITY SAMPLING • The following describes current sampling procedure. The order in which the different wells are sampled is determined by the salinity of each well. Wells with the lowest salinity value are sampled first to protect against contamination' from higher salinity wells. After examining the condition ~~. of the well, the cap is removed and static water level is measured from the toA of the well casing and recorded. A one liter sample bailer is used to remove five bailer volumes of water. The fifth bailer volume is used to rinse the field sample containers, sixth bailer volume is used to fill the field sample containers, a seventh bailer volume is used to fill the sealed bottle provided by the lab. Field samples are then analyzed and values recorded for temperature, pH, and electrical conductivity. At this time, a submersible pump is then used to evacuate the well of three well volumes, calculated by the static water level, total depth of the well, and casing volume. The well is pumped the required time, then the fore mentioned bailer sample procedure is repeated. Again, field analyses are completed and recorded for temperature, pH, and electrical conductivity. Lab samples are stored in an insulated container and transported at the earliest possible date. • All wells are sampled with the above sampling procedure. The following is the sequence in which wells are sampled: FPW, DH122, DH96, AMW-1, and SMW-2. Historically, this has been the order from least salinity to greatest salinity wells. Ash Monitoring Well ("AMW-2") remained dry in 1994. This well is located on the North-East edge of old "A" Pit (Cell) in a highly disturbed reclaimed-overburden area. Since the Well was redrilled in 1993 to the Divisions specifications, one can only presume recharge has not occurred in this area. In addition, faulty areas were evident in the coal seam to the west of the well location, which could effect the recharge process. AHR-1994 -26- STIPULATION #5
