OBSERVED RELEASES FOR ARSENIC, MANGANESE, AND NICKEL WERE ALSO DOCUMENTED IN THE STREAM SEDIMENT SAMPLES. THE UPSTREAM SEDIMENT MERCURY CONCENTRATION WAS SIGNIFICANTLY ELEVATED AT 22.5 MG/KG. ONE POTENTIALLY HAZARDOUS ADIT OPENING WAS IDENTIFIED APPROXIMATELY 0.5 MILE ABOVE THIS SITE. BOTH TAILINGS IMPOUNDMENTS HAD UNSTABLE SLOPES DOWN TO THE STREAM, AND BOTH TAILINGS DAMS HAD BEEN BREACHED.
