چکیده

The presence of chlorinated solvents polluting groundwater in urbanized areas poses a significant environmental issue. This paper details thoughtful approach to remediate tetrachloroethylene (PCE) plume district that is characterized by complex hydrological context with limited accessibility. Through geodatabase-driven and coupled hydrogeochemical approach, two distinct remediation technologies were chosen for the management contaminant plume. On one hand, coaxial circulation (CGC) wells air sparging (AS) aspire promote in-situ transfer PCE from contaminated matrices into gaseous stream then treated above ground. other reagent injection has goal enhancing chemical reduction combined situ adsorption, creating adsorbent zones, stimulating dechlorinating biological activity. development an integrated conceptual site model (CSM) harmonizing geological, hydrochemical, membrane interface probe (MIP) data captures site-specific peculiarities support decision-making. hydrochemical monitoring reveals contamination dynamics decontamination mechanisms response treatment, quantifying performance adopted strategies investigating possible rebound effects. estimation masses extracted CGC-AS system validates effectiveness new sustainable technique abate groundwater.
