June 1997 Water Samples 2 September 16, 1997 <br /> Howardsville Mill M-84-049 <br /> Given the complex hydrologic situation at the Howardsville Mill permit area, DMG <br /> requires that Animas River sample taken from the downstream S6 location, be a depth <br /> and width integrated sample. DMG recommends that all samples taken from the Animas <br /> River be depth and width integrated samples. <br /> Analysis report results of the two surface samples taken from the Upland Diversion Ditch, <br /> S1 and S2, indicate that the water within the ditch is of significantly lower quality than <br /> that of the Animas River. Analysis results at S1 suggest that S1 may be hydrologically <br /> downgradient from the Upper Tailings Pond and/or the Ore Stockpile Area. Analysis <br /> results at S2 indicate that S2 was taken in the backwater section of the ditch, where <br /> ditch flow had been diluted by Animas River flow. Please ensure that S2 sample is taken <br /> from a portion of ditch where positive drainage is evident. <br /> Please contact me at the DMG Durango office, 484 Turner Drive, Building F, Suite 101 , <br /> Durango, CO 81301 , phone (970) 247-5193, if you have any questions. <br /> Sincerely, <br /> Wallace H. Erickson <br /> Environmental Protection Specialist <br /> cc: Joe Baldwin <br /> Harry Posey <br />
