<br />' January 7997 Kerr Coal Company " 1996 Annual Hydrology Report "CO Permit No. C~80~006 ~ 1 <br />2.0 MONITORING AND ANALYSES <br />Water monitoring activities during the 1996 water yeaz (Ott. 1995 through Sept. 1996) were <br />' conducted according to the schedule contained in the Kerr Water Monitoring Plan submitted <br />during the 1991 midterm review and permit renewal. During a State of Colorado Division of <br />Mining and Geology inspection visit in early April, it was discovered that the operator was <br />' collecting water samples from the first bail at the top of the well. The Division recommended that <br />three casing volumes be evacuated from wells before collecting a sample and field data. In response <br />to this recommendation, Kerr Coal Company retained an independent sampler (Miller Water <br />' Monitor Services) to collect samples and data from the wells in the mine area coal aquifer (79-61) <br />and the mine area overburden aquifer (79-1 and 79-1) starting with the April 1996 sampling event. <br />All other field data and sample collection for the 1996 water year was conducted by James <br />' Mossman of Kerr Coal Company. Sample analyses were performed by ACZ Laboratories, Inc. <br />of Steamboat Springs, Colorado. <br />' This report discusses the ground water and surface water monitoring activities and atttttnarizes the <br />data collected during the 1996 water year in the following secuons: <br /> • Section 3 -Mine Area Confined Ground Water <br />' • Section 4 -Mine Area Alluvial Ground Water <br /> • Section 5 -Loadout Area Alluvial Gtound Water <br /> • Section 6 -Mine Area Surface Water <br />' • Settton 7 -Loadout Area Surface Water <br /> • Section 8 -Well Inspection <br />' • Section 9 -Future Monitoring <br /> Field data and laboratory data are included in Exhibits A through I.
