Sample Point - TB1 |
Sample Point Description: An existing treatment pond at the H&D (Adobe) "McIntire" minesite, which has since been incorporated into part of the passive treatment system; Prior to installation of the passive system, samples were generally sampled at the spillway as the effluent pipe had become plugged with low pH iron; TB1 receives the MC1, MC2, and MC3 mine discharges; Currently TB1 is sampled at the spillway of the pond as it enters the Oxidation Precipitation Channel. Prior to the passive system, TB1 flowed into an existing channel and was located upstream of sampling point TRX;

Sample Point Description: RS2 sample point after construction of the McIntire passive treatment system; Reconstructed stream channel; Unnamed "McIntire" tributary #15 to Blacks Creek; Sample point located below RS1 prior to flowing into existing Settling Basin 1 (SB1); Prior to construction of the passive treatment system this was the last sample point along the reconstructed stream channel carrying the mine discharge; After construction of the system, the channel carries other encountered surface and subsurface waters. See RS2 (pre-treatment) for data before passive treatment construction
