Honeywood Coal Company <br />1998 Annual Hydrologic Report <br />Page 3 <br />SP-6 also located in Bramiers Draw, has recorded flow during two calendar quarters (1991 - <br />1998). The maximum flow was 1.8 gpm which was measured during the first quarter of 1991. <br />During 1997, SP-6 was noted as damp during the second quarter and dry during the fourth quarter <br />monitoring event. <br />Alluvial Wells <br />Four alluvial wells, AW-4 & AW-5, AW-6 & AW-7 were installed to determine if the quality of <br />water in the alluvium near the alluvial valley floor near the San Miguel River is impacted by the <br />mining operation. Two wells are located along Bramiers Draw AW-4 & AW-5 and two are <br />installed along Naturita Creek AW-6 & AW-7. The wells in each drainage, are located up <br />gradient and down gradient of the Reed Chatfield irrigation ditch. The quality of water in the <br />imgazion ditch is also monitored to supplement the alluvial well monitoring data. <br />The purpose of the alluvial wells is to determine if the quality of water in the alluvium is impacted <br />by the mining operation. Two 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 impacted, yet the water in the <br />alluvium down gradient is not impacted. Since an alluvial valley floor is down gradient of the <br />irrigation ditch, the distinction between the two monitoring points is important. <br />AW-4 and AW-5, located in Bramiers Draw, were dry during the period 1992 through 1998. <br />AW-6 had measurable wazer during the second and fourth quarters. AW-7 had measurable water <br />during the second quarter but was dry during the fourth quarter monitoring event. The Reed <br />Chatfield Ditch, monitoring point R-l, dry during the 1998 monitoring events. <br />Bedrock Wells <br />Two bedrock wells are located adjacent to the mining area and one well is located within the <br />permit area BW-1, located east of the mining area has contained measurable quantities of water <br />during most monitoring events. BW-1 contained water during the second and fourth quarter <br />monitoring events. <br />~ BW-2 is located in the northwest comer of the permit area. The well was dry during 1998. <br />J BW-3 is located southeast of the mining area. This well has contained measurable quantities of <br />water during two monitoring events, from the fourth quarter of ] 990 through 1998. The well was <br />noted as dry during 1998. <br />
