Abstract Engineered injection and extraction (EIE) is an in situ groundwater remediation strategy that imposes engineered spatially temporally varying velocity field to spread amendment into the contaminant plume promote mixing degradation through reaction. Here we present a coordinated suite of laboratory experiments numerical simulations apply EIE using two pumping sequences: A folding sequence manipulates geometry by stretching folding, oscillating perpendicular interface accordance with...
Abstract Spreading and mixing are complementary processes that promote reaction of two reactive aqueous solutes present in contiguous plumes groundwater. reconfigures the plume geometry, elongating interface between plumes, while increases volume aquifer occupied by each plume, bringing solute molecules together to react. Since only occurs where contact with other, local mechanisms drive flow transport near control amount reaction. This work uses characteristics field analyze relative...
During in situ groundwater remediation, reactions occur a narrow reaction front which the amendment and contaminant are close enough to mix. Active spreading, injection or extraction wells create spatially variable velocity fields, can be used increase surface area of front, thereby enhancing reaction. This study four active spreading flow fields that building blocks more complex remediation hydraulics evaluate how field plume position control degradation both homogeneous heterogeneous...
During in situ remediation of contaminated groundwater, a chemical or biological amendment is introduced into contaminant plume to react with and degrade the contaminant. Since degradation reactions only occur where are sufficiently close, success controlled by degree which spreads plume. Spreading defined as reconfiguration geometry, occurs result spatially temporally varying flow fields. can passively due velocity caused aquifer heterogeneity. also actively inducing fields through...
During in situ groundwater remediation, a chemical or biological amendment is introduced into the aquifer to react with and remediate contaminated groundwater. The success of this type remediation depends on degree which contact contaminant. Remediation reactions only occur where contaminant molecules are sufficiently close that they can be brought together by mixing, i.e., processes such as molecular diffusion small-scale mechanical dispersion lead smoothing concentration gradients at...
