| Environmental Factors | IN FEBRUARY 1992, SAMPLES WERE TAKEN IN THE CAMBRIA MINE TRIBUTARY, IN SAN SIMEON CREEK ABOVE THE TRIBUTARY, AND IN SAN SIMEON CREEK BELOW THE TRIBUTARY. WATER SAMPLED IN THE CAMBRIA MINE AND ASSOCIATED MINES TRIBUTARY CONTAINED MORE CARBONATE, CALCIUM CARBONATE, BICARBONATE, MAGNESIUM, SULFATE, TOTAL IRON, TOTAL CHROMIUM, TOTAL MERCURY, AND TOTAL NICKEL THAN THE OTHER TWO SAMPLES. SEDIMENT SAMPLES CONTAINED MORE MERCURY, IRON, NICKEL, AND CHROMIUM. THESE ELEVATED CONSTITUENTS APPEAR MINE RELATED. THE SAN SIMEON CREEK SAMPLE BELOW THE CAMBRIA MINE TRIBUTARY CONTAINED MORE TOTAL FILTERABLE RESIDUE AND SULFATE THAN IN THE SAN SIMEON CREEK SAMPLE COLLECTED ABOVE THE CAMBRIA MINE TRIBUTARY. SEDIMENT COLLECTED BELOW THE CONFLUENCE OF THE TRIBUTARY CONTAINED MORE IRON, MERCURY, AND NICKEL THAN SEDIMENT FROM ABOVE THE CONFLUENCE. THESE ELEVATED CONSTITUTENTS ALSO APPEAR MINE RELATED. SEDIMENT COLLECTED IN THE SAN SIMEON CREEK ABOVE THE CAMBRIA MINE TRIBUTARY CONTAINED MORE TOTAL FILTERABLE RESIDUE AND SULFATE THAN IN THE SAN SIMEON CREEK SAMPLE COLLETEC ABOVE THE CAMBRIA MINE TRIBUTARY. SEDIMENT COLLECTED BELOW THE CONFLUENCE OF THE TRIBUTARY CONTAINED MORE IRON, MERCURY, AND NICKEL THAN SEDIMENT FROM ABOVE THE CONFLUENCE. THESE ELEVATED CONSTITUTENTS ALSO APPEAR MINE RELATED. SEDIMENT COLLECTED IN THE SAN SIMEON CREEK ABOVE THE CAMBRIA TRIBUTARY CONTAINED ELEVATED ANTIMONY, ARSENIC, AND LEAD, INDICATING AN UPSTREAM SOURCE (POSSIBLY THE HAMILTON MINE). |
