' A, TR-B, TR-C and TR-D for the period of record. Chloride and potassium were added to the <br />monitoring program in 1993 while iron was added in 1994. The concentrations of all of these <br />' parameters in Trout Creek water are generally low. The 2009 sampling period shows consistent <br />sampling results to the previous monitoring events regarding these constituents. Chloride and <br />potassium have shown a trend decrease and stabilization over the past decade. Iron levels during <br />' the past few monitoring periods slightly decreased relative to those since 2004 showing a general <br />relation to flow in Trout Creek. The lowest chloride concentration in 2009 was <1.0 mg/L at <br />monitoring site TR-A in April and TR-A and TR-B in August and the high was recorded at <br />' monitoring sites TR-B, TR-C and TR-D in April and TR-C and TR-D in August with a value of <br />2.0 mg/L. The lowest potassium concentration in 2009 was recorded at monitoring site TR-A in <br />' August with a value of 1.0 mg/L and the high was recorded at monitoring sites TR-C and TR-D <br />in April with a value of 2.6 mg/L. The lowest iron concentration in 2009 was recorded at <br />monitoring site TR-D in August with a value of 0.07 mg/L and the high was recorded at <br />' monitoring site TR-D in April with a value of 0.42 mg/L. <br />^?WWCENGINEERING Page 10
