Simultaneous counter-flow of chlorinated volatile organic compounds across the saturated-unsaturated interface region of an aquifer. Academic Article uri icon

abstract

  • Concentrations of chlorinated volatile organic compounds (Cl-VOCs) at the saturated– unsaturated interface region (SUIR; depth of∼ 18 m) of a sandy phreatic aquifer were measured in two monitoring wells located 25 m apart. The concentrations of the Cl-VOCs obtained above and below the water table along a 413-day period are interpreted to depict variable, simultaneous and independent movement of trichlorothene, tetrachloroethene, 1, 1- dichloroethene, cis-1, 2-dichloroethene, 1, 1, 1-trichloroethane, chloroform and 1, 1- dichloroethane vapors in opposite directions across the SUIR.
