69. A method for determining a subsurface contaminant remediation protocol, comprising:
-
collecting a soil sample from the subsurface; identifying at least one target contaminant for concentration reduction; choosing a surfactant and optionally choosing a cosolvent for injection into the subsurface to solubilize the at least one target contaminant; choosing an oxidant and optionally choosing an activator for the oxidant for injection into the subsurface to oxidize the target contaminant; and choosing the quantity of surfactant for injection into the subsurface to form a Winsor I system or a submicellar surfactant solution or a microemulsion. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)

81. A method for determining a subsurface contaminant remediation protocol, comprising:
-
collecting a soil sample from the subsurface; identifying at least one target contaminant for concentration reduction; choosing a surfactant or surfactants and optionally choosing a solvent for injection into the subsurface to desorb and solubilize the at least one target contaminant; choosing an oxidant and optionally choosing an activator for injection into the subsurface to oxidize the target contaminant; choosing the quantity of surfactant for injection into the subsurface to form a Winsor I system or a microemulsion; determining the spatial concentration distribution of the target contaminant; determining a hydrogeological property of the subsurface; and using the determined spatial concentration distribution of the target contaminant and the hydrogeological property to determine the target depth for the surfactant and oxidant and optionally for the solvent and activator. - View Dependent Claims (82, 83, 84, 85, 86, 87, 88)
