Samples for analysis of addition all <br />metals, nitrate, nitrite, and fatty acids will be collected <br />at each location; these samples will be held and analyzed <br />only if the cyanide values indicate possible interfere~hce, <br />Please cell me immediately it you disagree in any way With <br />the items outlined above or if you have any questions. <br />Si~~nhcerel^y~, <br />(~-~1o,r~a o1 ~~ <br />Alana L.
