Spring #12: Apache Canyon (Table 2) . This seep originates <br /> from the interface of shale and sandstone . Flow was measured in <br /> each of the samplings ranging from <1 to 5 gallons per minute <br /> (gpm) . Flow was absorbed back into the alluvium within 100 yards <br /> of the source during every observation. As a result, this seep <br /> is not a significant source of surface flow. Conductivity of the <br /> water was stable, ranging from 629 to 768 , while pH ranged from <br /> 6 . 3 to 8 . 2 . Use of the water is limited to livestock and <br /> wildlife watering. <br /> Spring #13 : Apache Canyon (Table 3 ) . This seep originates <br /> from the interface of shale and sandstone. Flow was measured on <br /> 8 of the 10 samplings ranging from <1 to 3 gpm. The flow was <br /> absorbed into the alluvium within 50 yards of the source during <br /> each of the 8 observations . As a result , this seep is not a <br /> significant source of surface flow. Water quality measurements <br /> of conductivity range from 700 to 721 , while pH ranged from 6 . 1 <br /> to 7 .7 . Use of the seepage is limited to livestock and wildlife <br /> watering. <br /> ' Spring # 14 : Apache Canyon (Table 4 ) . This is a USGS <br /> developed spring originating from an upper coal seam or interface <br /> between coal and shale or sandstone. Flow could not be measured <br /> because of the associated pond at the site , however, water levels <br /> in the pond appeared to be constant over the monitoring period. <br /> This spring does not contribute to Apache Canyon stream flow <br /> because an embankment creating the pond separates the two. <br /> Conductivity ranged from 535 to 739 , while pH ranged from 7 . 4 to <br /> 8 . 9 . Use of the water is limited to livestock and wildlife <br /> watering. <br /> Spring #15 : Ciruela Canyon (Table 5 ) . Spring # 15 is a <br /> minor area of seepage from the interface of shale and sandstone <br /> below a coal seam outcrop. No flow or flow of less than 1 gpm <br /> was measured during the monitoring period. Water quality was <br /> measured on two occasion with conductivity at 924 to 1054 and pH <br /> -77- <br />
