摘要: Abstract In this study,concentration and δ 13 C 37 Cl values of chloroform (CF) carbon tetrachloride (CT) measured in groundwater samples are related to redox conditions elucidate natural attenuation processes a polluted site. Shifts CF CT were detected over time.δ found the potential sources -34.5 ± 0.6 ‰ (tank near S3 well), -37.3 (in fracture S1 well) -46.2± 0.4 (barrels) 2004, whereas later sampling campaigns, enriched such as -25.2 0.5 2013. 2D plots (δ vs ) showed different isotopic patterns wells depths. let distinguish that former evolved towards completely signatures, whilst +1.3 0.3 reached 2013 for S3,S1 moved more depleted (down -3.9 0.6‰). These data indicate differentreductive dechlorination might occur.
