URS Operating Services, Inc. <br />STARTZ, EPA Region VIII <br />Contract No. 68-W -00~ I I B <br />Bartle Mountain Gold -Trip Report <br />Revision: 0 <br />Date 9/?000 <br />Page 2 0(I Z <br />The first surface water sample, RSR-06B, was collected from an abandoned stream channel on the south side <br />of the Rito Seco from the Shalom Ranch owned by Mr. Harris Cooper. The water in the channel was <br />approximately one inch deep, stagnant, with algae groW2h, and a rust colored precipitate covered the sediment <br />in the channel (Photograph 1). The second sample, RSR-06A, was the most downstream sample and was <br />collected from another abandoned stream channel in a marshy area along the Rito Seco on the Shalom Ranch <br />(Photograph 2). The water at this location was stagnant and supported a noticeable growth of algae. <br />Samples numbered RS-O1, RS-02, RS-OS were collected from established sampling locations on Battle <br />Mountain property, Ron Zumwalt, Battle Mountain Site Manager (719-672-3362) and Julio Madrid, Battle <br />Mountain sampling technician, collected split samples at all of these locations after Battle 1v(ountain allowed <br />EPA access to [he property. Sample RS-OS was collected on the Rito Seco just before the stream left [he <br />Battle Mountain property (Photograph 3). Sample RS-02 was collected from the Rito Seco near the mid-area <br />of the Battle Mountain site (Photograph 4). Sample RS-01 was collected from the Rito Seal upstream of the <br />site as a background sample. Duplicate sample RS-10 was collected at the background sample site location. <br />Sample BAS was collected from a seep on the south side of the Rito Seco directly across the stream from the <br />facility buildings. It was reported by Mr. McGowan that the seep was flowing from a reel timed area. The <br />seep water registered the lowest pH and highest conductivity of all the samples collected at t ie site (Table 1). <br />All of the water samples were collected as grab samples for total metals analysis. The s.tmples were not <br />filtered. Even though an effort was made [o collect only water from [he two shallow aband ~ned channels at <br />RSR-06A and RSR-06B a noticable amount of solid material, in the nature of algal growth and a precipitate <br />like material, was caught up in [he water collected for these samples. <br />ANALYTICAL RESULTS <br />A review of the analytical data presented in Table 2 indicates that concentrations of metals iri the water of the <br />Rito Seco increase from the background sample (RS-Ol) to the most downstream sample (RS-OS) for the <br />metals aluminum, barium, calcium, iron, magnesium, manganese, and sodium. Cyanide arld mercury were <br />not detected in any samples from the main body of the Rito Seco. <br />~s-oovezao <br />P:~Siart2~Baule Mounain Gold~trip_report.wpd:bas <br />
