' Honeywood Coal Company <br />1992 Annual Hydrologic Report <br />' Page 3 <br />irrigation ditch is also monitored to supplement the alluvial well <br />' monitoring data. <br />The purpose of the alluvial wells is to determine if the quality of <br />water in the alluvium is impacted by the mining operation. Two <br />' wells are utilized at each location because it is possible that the <br />water in the alluvium up gradient of the irrigation ditch will be <br />impacted, yet the water in the alluvium down gradient is not <br />impacted. Since an alluvial valley floor is down gradient of the <br />irrigation ditch, the distinction between the two monitoring points <br />is important. <br />AW-4 and AW-5, located in Bramiers Draw, were dry during 1992. AW- <br />6 contained water during all four quarters of 1992. AW-7 was dry <br />during the last two quarters of 1992. The Reed Chatfield Ditch, <br />' monitoring point R-1, had flow during the second and third quarters <br />of 1992, during the irrigation season. <br />' The quality of the water in AW-6 and AW-7 is similar. It appears <br />that the water in AW-7 is diluted slightly by seepage water from <br />the Reed Chatfield Ditch. <br />t AW-3 is located within the permit area in Section 33 Creek. This <br />alluvial well has been dry during four years of monitoring, 1989 <br />through 1992. <br />Bedrock Wells <br />' Two bedrock wells are located adjacent to the mining area and one <br />well is located within the permit area. BW-1, located east of the <br />mining area has contained measurable quantities of water during all <br />eight quarters of monitoring. During 1992, three samples were <br />' obtained and analyzed. During the fourth quarter of 1992, the well <br />was inaccessible. <br />' BW-2 is located in the northwest corner of the permit area. This <br />well has not contained measurable quantities of water during nine <br />monitoring quarters, from the fourth quarter of 1990 through 1992. <br />' BW-3 is located southeast of the mining area. This well has <br />contained measurable quantities of water during two of nine <br />calendar quarters, from the fourth quarter of 1990 through 1992. <br />' During the first quarter of 1992 a sample was obtained. During the <br />remainder of 1992 the well was noted as dry. <br />' Consumptive Use <br />Consumptive use of water at the mine is for dust control. During <br />the year a water truck obtained water from Naturita Creek as <br />1 <br />
