| Environmental Factors | NO MILL TAILINGS WERE OBSERVED AT THIS SITE DURING THE INVESTIGATION. THERE WAS ONE ADIT DISCHARGE. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED IN THE ADIT DISCHARGE SAMPLE. THREE HAZARDOUS MINE OPENINGS (TWO OPEN SHAFTS AND ONE CAVED SHAFT) WERE OBSERVED AT THIS SITE. TWO OF THE OPENINGS WERE SURROUNDED BY BARBED WIRE; HOWEVER, THE BARBED WIRE WAS VERY LOOSE AND DID NOT INCLUDE ANY WARNING SIGNS. |
