lJ <br />31 <br />of metals and radioactivity were measured in this sample. The sample was not <br />collected from the monitoring station for approximately one week after the <br />runoff event, due to lack of notification of the occurrence. However, this <br />should not change the results since anaiysie•is for concentrations of total <br />constituents rather than dissolved constituents (i.e., sediment and eater <br />rather than just water). However, the high levels were almost certainly a <br />result of the high suspended sediment concentration. <br />Malysis of samples taken from three sediment ponds at G.E.C. (Exhibits <br />2 and 3) also demonstrate the effect of high suspended sediment concentration <br />on total iron and manganese. The high levels of accumulated sediment in the <br />ponds demonstrates the need for: (1) an adequate sediment control plan; and <br />~. (2) regular maintenance of sediment ponds. <br />r <br /> <br />
