Abstract
When performing in situ remediation, different fluids are injected into the ground. The injections can affect the properties of the ground, such as opening up new fractures and reactivating old ones. The fluids also differ in viscosity and density and could possibly clog some of the pores or fractures, thus affecting the groundwater flow. We have measured hydraulic conductivity and compared our results to background measurements. Thereafter we have built a model in FEFLOW of a PCE contaminated site in Alingsås to help us interpret the flow processes during injection. This model can in the future help us understand the movements of the contaminants during injection for in situ remediation. The work is part of the MIRACHL (characterization... (More)
