Caller is going out to investigate. She <br />said there is some suspicion prior to the visit, that this may be related to some type of mining activity. // 10/5/11 Boulder <br />County Sheriff &news reports provided more information. The Alicia Mine, a gold mine, at 1500 James Canyon Drive, <br />had previously had a stagnant pool of this water inside the mine. Somehow the pool was released into the creek, for a <br />one -time release. Boulder County officials were notified in time to close an intake that would have channeled the mine <br />effluent into one of the reservoirs that provides part of the district's water supply. Water samples at the time were <br />negative for arsenic, cyanide, mercury and iron. It is though at this time that the orange coloring is due to iron oxide. <br />The orange liquid had no odor, and reportedly had the consistency or thin pancake batter. <br />MEDIUM IMPACTED: WATER • Fixed Facility ❑ Land ❑ Air • Groundwater <br />MI Surface Water Waterway Impacted: <br />JAMES CREEK - - >LT HAND CREEK - - >ST.
