Some values during the 2nd Quarter of 1989 were <br />excluded due to question raised by permittee regarding sampling or analytical <br />procedure used. <br />* = Reported as "ND" (Not Detected); the assumed minimum level of detection is <br />included in table. <br />For the mean calculation determination, values below the minimum level of <br />detection were equated to 0.00 mq/1. Far example, for Total Recoverable <br />Cadmium, 80.0001 mq/1 is equivalent to 0.00 mg/1, and K0.00165 mg/1 is <br />calculated as 0.0016499 mq/1. <br />
