Sample types include water (acid mine drainage, groundwater, and surface water) and solid media (soil, mine drainage precipitates, rock, waste rock, mine tailings). In the additional attachment, “Analyses Requested Spreadsheet”, there are 11 different types of laboratory analyses that DRMS needs completed upon request of the awarded Offeror(s) throughout the 5 year duration of the contract agreement.
