Review of samples of sediment, tailings, and waters adjacent to the Cactus Queen gold mine, Kern County, California
Mine tailings here have high levels of arsenic. Experiments conducted on these sediments indicate that the arsenic can be released into the environment and become hazardous through chemical processes that occur when fine sediment is ingested by animals. |
