The water <br />samples collected during this event cover the April 28-29 <br />biweekly and the April 1993 quarterly. The cross-refBrence <br />table between sample identification numbers and sample <br />locations is attached. <br />This sampling event coincided with the third site visit of <br />the independent third party sampler, Dr. Ann Maest of <br />RCG/Hagler, Bailly, Inc. As part of the third party <br />sampling, filtered and unfiltered samples for the analysis <br />of cyanide (total and wad), metals, and nitrate/nitrite were <br />collected from the three ponds. RS-5 was sampled twine - a <br />sample during the third party visit (930428 BMG O1, analyzed <br />for cyanide, metals, and nitrate/nitrite) and a bi- <br />weekly/quarterly sample (930429 BMG 04, analyzed for <br />complete parameters list). <br />As specified in TR-006, calculated free and wad cyanidle <br />values for the process point samples are enclosed. <br />No deviations from the sampling QA/QC protocols, TR-OOi6, <br />were noted for any of the samples collected. Wells M-1, M- <br />4, M-9, M-10, M-11, M-12, M-13, and D87-24 were sampled. <br />Samples were collected at surface water stations RS-1, RS-2, <br />and RS-5. The five process points were sampled. Wells M-2, <br />M-6, M-7, and M-8, surface water stations RS-3, RS-4, and <br />RS-6, and the three lysimeter pairs were checked and found <br />to be dry. A barrel filter rinse blank, a field blank, and <br />a duplicate sample at D87-24 were collected as field quality <br />control samples. <br />A SURS/D/AHY OF flA77LF.
