• water year 1999. Trace flow was recorded at the Haulroad Spring, during November <br />1998, however the amount was insufficient to measwe accurately. <br />Temperatures of spring flow aze seasonally related. During the winter and early spring, <br />temperatwes aze lower. With the onset of warmer weather, spring temperatures rise. <br />This phenomenon appeazs to support the conjectwe that these springs aze shallow and <br />recharged lazgely by winter snowmelt. Spring temperatwes during this water year were <br />consistent with the temperatwes observed during prior water years. A temperatwe <br />reading for the Haulroad Spring was not recorded due to the trace and shallow natwe of <br />the flow for this spring during the sampling event. <br />pH values of the springs fluctuate seasonally, with values remaining on the slightly basic <br />side. Values fluctuated between 7.2 and 7.8 standard pH units from water yeaz 1995 to <br />water yeaz 1999. The pH values are not particulazly well correlated to flow rate or spring <br />temperatwe. Electrical conductivity (EC) is duectly related to the concentration of ions in <br />the water. As would be expected, the springs show decreased electrical conductivity <br />readings during the high flow conditions of late winter and early spring and increased <br />values with decreased flow. Fluctuations in both pH and EC values during the 1999 water <br />year were within the range of fluctuations observed in prior water years. Readings for pH <br />and EC at the Haulroad Spring were not recorded due to the diffuse and trace natwe of <br />this springs flow. <br />• Total dissolved solids (TDS) concentrations remained consistent in spring discharges <br />during this water yeaz. Concentrations were lower during high flow and higher dwing low <br />flow conditions. Total suspended solids (TSS) concentrations remained low in both <br />Springs 3 and 4 this water yeaz. The initial value for TDS at the HauUoad Spring <br />indicates levels less than half of those at Springs 3 and 4. TSS levels at the Haulroad <br />Spring were significantly higher than those at Springs 3 and 4. This is attributed as an <br />artifact of sampling this low-flow diffuse spring, where solids from the surrounding <br />surface likely made their way into this sample. <br />Dwing the 1999 water yeaz alkalinity, bicarbonate, calcium, chloride, magnesium, <br />manganese, sodium, sodium adsorption ratio, and sulfate revealed concentrations that <br />remained within the observed historic ranges for Springs 3 and 4. The only notable <br />exception was the decrease in total and dissolved manganese concentrations in Spring # 4 <br />during the 1998 and 1999 water years. At the Hauhoad Spring, constituent <br />concentrations for alkalinity, bicarbonate, manganese, and SAR are within the <br />concentrations observed for Springs 3 and 4. Concentrations of calcium, chloride, <br />magnesium, sodium, and sulfate at the Haulroad Spring were notably lower than those at <br />Springs 3 and 4 during this water yeaz. <br />Many trace elements were consistently found to be near or below the detectable limits for <br />all springs for the 1999 water year. These same trace elements have historically been <br />found to be below detectable limits. They are aluminum, ammonia, azsenic, cadmium, <br />L~ <br />-4- <br />
