Model assessment of reductive dechlorination as a remediation technology for contaminant sources in fractured clay: Case studies

Title:
Model assessment of reductive dechlorination as a remediation technology for contaminant sources in fractured clay: Case studies

Subtitle
Delrapport III

Abstract:
The numerical model developed in Delrapport II is applied to three Danish sites contaminated with chlorinated solvents in clayey till. The cleanup times to achieve defined remediation criteria are assessed for different remediation scenarios: they are significantly reduced compared to baseline, but are still of several decades. Good distribution of substrate and bacteria as well as high reaction rates should be achieved to ensure an efficient remediation.

Notes:
Den numeriske model udviklet i Delarpport II er afprøvet på tre danske morænelerslokaliteter forurenet med chlorerede opløsningsmidler. Oprensningstider for at opnå defineret oprensningskriterier vurderes for forskellige oprensningsscenarier. Oprensningstider reduceres betydeligt i forhold til baseline, men tager stadig flere årtier. En god fordeling af substrat og bakterier samt høje reaktionsrater bør opnås for at sikre en effektiv oprensning.
