Mr. G. Becenti, <br />October 7, 2005 <br />Water quality samples were taken at the upper and lower weir locations on April 20, May I0, and <br />Ma.y 25, 2005. No sample was taken in June because the lower weir was dry. The results of the <br />chemical analyses are shown in Table 1. Results from the 2004 sampling rounds are included in Table <br />2 for comparison. For some constituents, both total and dissolved analyses are shown. The total <br />analyses generally show higher constituent levels since they include any sediment /colloidal matter <br />contained in the water as well as the dissolved constituents. A comparison of the results to the <br />agricultural standard goals set out in the August 23, 2002 plan is included. <br />Table 1 2005 Windy Gulch water quality <br /> <br />Parameter <br />4/20/05 Upper Weir <br />5/10/05 <br />5/25/05 <br />4/20/05 Lower Weir <br />5/30/OS <br />5/25/05 <br />luminum total (mg/1) 1.70 1.49 L26 0.40 0.97 0.77 <br />epic dissolved (mg/I) 0.0016 <0.003 0.0023 O.O133 O.OI58 0.0195 <br />epic total (mg/p 0.0021 0.0022 0.0024 0.0118 0.0193 0.0220 <br />admium dissolved (mg/I) <0.005 <0.005 <0.005 0.013 <0.005 0.006 <br />admium total (mg/q <0.005 <0.005 <0.005 0.015 <0.005 0.005 <br />opper dissolved (mg/1) <0.01 <0.01 0.08 0.02 <O.OI <0.01 <br />opper total(mg/p <0.01 <0.01 <O.Ot <0.01 <0.01 0.01 <br />on dissolved (mg/1) 0.15 0.1 I O.13 0.05 0.10 0.10 <br />Uon total (mg/p I.08 0.98 0.67 0.21 0.62 0.47 <br />anganese dissolved (mg/1) 0.022 0.006 0.025 0.034 0.057 0.047 <br />anganese total (mg/q 0.048 0.032 0.029 0.037 0.057 0.047 <br />ercury dissolved (mg/l) <0.0002 <0,0002 <0.0002 <0.0002 <0.0002 <0.0002 <br />ercury total (mgn) <0.0002 <0.0002 <0.0002 <0.0002 <0.0002 <0.0002 <br />inc dissolved (mg/1) <O.OI <D.OI 0.09 3.12 0.97 0.89 <br />inc total (mg/p <0.01 <0.01 <0.01 3.24 L00 0.96 <br />H (units) 7.0 7.4 7.7 6.5 7.0 7.5 <br />onduc[ivity (umhos/cm) 60 47 58 310 125 132 <br />S (mg/q 70 60 80 240 100 130 <br />SS (mg/1) 6 I2 <5 <5 l0 c5 <br />ulfate (mg/1) 50 <IO <IO 150 40 40 <br />
