fall. During yeazs with low snow pack, such as 1997-1998, flow rates are reduced when compazed with other years. No significant changes in spring flow were observed during water year 1998. Temperatures of spring flow are seasonally related. During the winter and early spring, temperatures are lower. With the onset of warmer weather, spring temperatures rise. This phenomenon appears to support the conjecture that these springs are shallow and recharged largely by winter snowmelt. Spring temperatures during this water yeaz were consistent with the temperatures observed during prior water yeazs. pH values of the springs fluctuate seasonally, with values remaining on the slightly basic side. Values fluctuated between 7.2 and 7.8 standard pH units from water yeaz 1995 to water year 1998. Electrical conductivity (EC) is dvectly related to the concentration of ions in the water. As would be expected, the springs show decreased electrical conductivity readings during the high flow conditions of late winter and eazly spring and increased values with decreased flow. Fluctuations in both pH and EC values during the 1998 water yeaz were within the range of fluctuations observed in prior water years. Total dissolved solids (TDS) concentrations remained consistent in spring dischazges during this water year. Concentrations were lower during high flow and higher during low flow conditions. Total suspended so Gds (TSS) concentrations remained low in both Springs 3 and 4 this water yeaz. During the 1998 water year alkalinity, bicarbonate, calcium, chloride, magnesium, manganese, sodium, sodium adsorption ratio, and sulfate revealed concentrations that remained within the observed historic ranges for the springs. Many trace elements were consistently found to be neaz or below the detectable Emits for all springs for the 1998 water yeaz. These same trace elements have historically been found to be below detectable limits. They aze aluminum, ammonia, arsenic, cadmium, copper, 'von, lead, mercury, molybdenum, nitrite, nitrate, nitrate/nitrite, phosphate, selenium, and zinc. The other trace elements tested at a detectable level aze for the most part consistent throughout the water year, with some characteristic variations between the springs. RESULTS -MONITORING WELLS FOR WATER YEAR 1998 Three wells were sampled during the 1998 water yeaz. The wells sampled were designated 17-B, 94-1, and 9S-l. Well 17-B is 600' west of the corner of the northwest permit boundary within Carbon Junction Canyon. Well 94-1 is located adjacent to the east edge of the south pit. Well 95-1 is located approximately 8S0 feet south-southwest of the future pit boundary. Well 17-B is located upgradient of any disturbance related to mining. WeG 94-] is located within the azea disturbed by mining, and well 95-1 is located -4-
