Weekly samples will be collected at Sites A and B for selected parameters. A sample will be collected on a daily basis for total selenium at Site B (outflow of the SLD) using a 24 bottle, integrating automatic sampler. Daily monitoring of selenium loads discharged is required for compliance evaluation. In addition, weekly depth-width integrated samples will be taken from the footbridges at Sites A and B for analysis of dissolved and suspended selenium concentrations in the drainage water.
