TL;DR: In this paper, a laboratory study was conducted to investigate the influence of microbial induced calcite precipitation (MICP) for improving the engineering properties of soil, and the results showed that MICP is one of the potential methods for improving soil properties.

TL;DR: In this paper, a laboratory study was conducted to investigate microbial-induced calcite precipitation (MICP) for improving engineering properties of sandy soil, and the results showed that MICP is one of the environmentally friendly ways to improve engineering properties.

TL;DR: Results of simulations conducted with the model show that the largest porosity reductions occur between the entrance and mid-plane of the PRB as a result of precipitation of carbonate minerals and that smaller porosity reduction occurs between the mid-planes and exit face due to precipitation of ferrous hydroxide.

TL;DR: Reactive transport simulations conducted to assess the impact of mineral fouling on the hydraulic behavior of continuous-wall permeable reactive barriers (PRBs) employing granular zero-valent iron in carbonate-rich alluvial aquifers show that porosity and hydraulic conductivity of the ZVI decrease over time and that flows are redistributed throughout the PRB in response to fouling of the pore space.

TL;DR: Ground water flow and geochemical reactive transport models were used to assess the effectiveness of five strategies used to limit fouling and to enhance the long-term hydraulic behavior of continuous-wall permeable reactive barriers (PRBs) employing granular zero valent iron (ZVI).
