Fractured bedrock aquifers can be extremely heterogeneous which not only results in complex dissolved plume behavior but can also hinder in situ remediation efforts that rely on subsurface injection of amendments to promote microbial activity and abiotic degradation. Simply put, injected amendments may bypass or have limited contact time with impacted zones due to transport differences within primary and secondary rock porosity and other subsurface heterogeneities. With thorough characterization of site hydrology, novel amendment formulations, routine performance monitoring, and an adaptive site management approach however,in situ remediation can be successful in fractured bedrock aquifers.

In this webinar we are pleased to have as a special guest speaker Matthew Burns, Technical Fellow and the in situ remediation Practice Leader for WSP. He presents a case study of a site where multifunctional amendments were applied to manage back diffusion of chlorinated VOCs from a fractured sandstone aquifer. Topics featured in the webinar include:

Large-scale pilot tests to assess management of chlorinated VOC back diffusion from fractured sandstone aquifer
Stimulating degradation along biotic and abiotic reductive pathways are complementary
The combined remedy extends treatment longevity to better manage long-term back diffusion
Costs compare favorably to conventional long-term pump and treat
