(BMRI) - San Luis s11- <br />DMG Permit No. M-88-112 I <br />Bi-weekly Water Sample Report <br />February 3-5, 1993 Sampling Event <br />Dear Mr. Oehler: <br />Enclosed are the analytical reports from Core Laboratmries <br />for the bi-weekly water samples collected on <br />February 3-5. 199 as specified in the April 1992 Aba#ement <br />Plan. The final analytical report from Core Labs was <br />received at the San Luis Mine on Ma 12 1993. The c3toss- <br />reference table between sample i entification numbers and <br />sample locations is attached. As specified in TR-006, <br />calculated free and wad cyanide values for the process point <br />samples are enclosed. <br />No deviations from the sampling 4A/4C protocols, TR-006, <br />were noted for any of the samples collected. However, it <br />should be noted that approximately eight inches of ice was <br />chipped from the surface of the RS-5 sampling location <br />before flowing water was reached. The sediments in the <br />stream bed were disturbed during ice removal. The stream <br />bed was given time (approximately 10 minutes) to settle, and <br />the flowing water was allowed to visibly clear. wells M-9, <br />M-12, and M-13, the five process points, and RS-5 were <br />sampled. Wells M-2, M-6, M-7, and M-8 and the three <br />lysimeter pairs were checked and found to be dry. A barrel <br />filter rinse blank and a field blank were taken as field <br />quality control samples. <br />The Core Labs analysis for total cyanide on samples frlom the <br />RS-5 station (930203 BMG O1), the upper pond (930203 BMG <br />02), the lower pond (930203 BMG 03), the collection potnd <br />(930203 BMG 04), and the post detox (930205 BMG O1) Ovals <br />performed after the EPA recommended holding time was <br />exceeded. Also, the analysis for ammonia and chloride on <br />the RS-5 station sample (930203 BMG O1) was performed after <br />the holding time was exceeded. A narrative from Core Labs <br />discussing these samples is attached. <br />A.SUBS/DIARY OF BA7TLF MOUN(A/N C,OLO COMPANY <br />P.O. BOX 31U SAN LUIS.
