Chloride <br />Chloride concentrations at Spring 3 over the past eight water years have remained <br />consistent, ranging from 34 to 50 mg/L throughout the period. Concentrations in Spring 4 <br />have decreased significantly over the same period until this water year. In the 1994 and <br />1995 water years, concentrations were in the 45-59 mg/L range, while the most recent <br />concentrations range between 29 and 34 mg/I, (2000 and 2001 water yeazs). This water <br />year, first quarter concentrations were elevated, at 54 mg/L, though they subsequently <br />dropped to 47 mg/L during the Mazch 2002 sampling. <br />Calcium <br />Calcium concentrations at both springs have remained consistent over the past seven <br />reporting years. Spring 3 concentrations (ranging from 400-515 mg/L) remain higher than <br />those of Spring 4 (ranging from 280-380 mg/L). <br />Magnesium <br />Spring 3 magnesium concentrations have remained variable but consistent over .the <br />reporting period, ranging from 170 to 250 mg/L. Spring 4 magnesium concentrations <br />have slightly decreased over the same period from averages in the 165 mg/L range (water <br />years 1995-1996) to an average in the 125 mg/L range during the 2000 and 2001 water <br />years. This water yeaz, Spring 4 magnesium concentrations were elevated during the <br />December and Mazch sampling, to levels within the higher end of the historic range. <br />Manganese <br />As with magnesium concentrations, manganese concentrations at the springs have shown <br />different trends over the reporting period. Concentrations at Spring 3 have remained <br />consistent and lower than Spring 4 during the reporting period, while concentrations at <br />Spring 4 have significantly decreased by an order of magnitude during the same time (from <br />2.3 mg/L (WI'1995) to 0.24 mg/I, (WY2001) total concentration). This water year, <br />manganese concentrations were at or close to the lower detection limits. <br />Sodium <br />Sodium concentrations at both springs have remained fairly variable over the last eight <br />yeazs. Spring 3 concentrations have remained in the 89-120 mg/L range, while Spring 4 <br />concentrations have fluctuated more, ranging from 96-150 mg/L. The highest <br />concentration was reported from the December 2001 sampling. The Mazch 2002 level <br />was lower and within the historic range. The sodium adsorption ratios for both springs <br />reflect the same overall trend as sodium concentrations. <br />Carbon Junct(on Mfna Page 8 <br />Annual Flydrobgle Raportfor Water Year?D02 <br />
