lower and barely above the historic range. The sodium adsorption ratios for both springs reflect the same overall trend as sodium concentrations. Spring 1 concentrations are significantly lower for sodium, with a lower calculated SAR value. Sulfate As with several other constituents, sulfate concentrations at Springs 3 and 4 remained consistent from water yeaz 1995 through water year 2001. The prior two water yeazs showed some elevation in concentrations in sulfate for both springs. The 1995-2001 ranges for Spring 3 were between 1440 and 2000 mg/L, while the last two water yeazs have revealed a range of between 1850 and 2300 mg/L,. Spring 4 values have show a comparable trend with the 1995-2001 range being 1100-1480 mg/L and the recent values ranging from 1700 to 2200 mg/L. This water yeaz Spring 3 values averaged 1850 mg/L, reduced from the higher levels of the prior two water years. Likewise, Spring 4 concentrations this year were 1500 mg/L, significantly lower than the prior two water years. Trace Elements Many trace elements were consistently found to be near or below the detectable limits for all springs for the 2004 water yeaz. These same trace elements have historically been found to be at or below detectable limits. They are aluminum, ammonia, arsenic, cadmium, copper, iron (both total and dissolved), lead, mercury, molybdenum, nitrite, nitrate, nitrate/nitrite, phosphate, selenium, and zinc. RESULTS -MONITORING WELLS FOR WATER YEAR 2004 Two groundwater monitoring wells were sampled during the 2004 water year. The wells sampled are designated 17-B and 95-1. Well 17-B is 600 feet west of the corner of the northwest permit boundary within Carbon Junction Canyon. We11 95-1 is located approximately 850 feet south-southwest of the future pit boundary. Well 17-B is located upgradient of any disturbance related to mining. Well 95-1 is located downgradient and outside the proposed coal mining disturbance. As such, well 95-1 would be expected to show any changes resulting from mining disturbance. Well 95-1 may also show changes to groundwater due to adjacent sand and gravel mining on Ewing Mesa. Wells 17-B and 95-1 were sampled twice in the first quarter (October 7, 2003 and December 18, 2003), and once during the second, third, and fourth quarters of the 2004 water year. Summaries of sampling data from the groundwater wells for the 2004 water year are contained in Tables 4, and 5. Gr6on Junction MMe Page 8 Annual kddrobgk Repartfor Wrtw Year 2A04
