Development of a Design Tool for Planning Aqueous Amendment Injection Systems Soluble Substrate Design Tool

Spreadsheet‐Based Design Tool for In Situ Anaerobic Bioremediation Using Soluble Substrate

“…The design tool then estimates steady-state contact efficiency and total project costs. CE SS is estimated using the regression equation developed in Borden et al (2012) and the ratio of injection to minimum TOC concentration, groundwater travel time between rows of injection wells, soluble substrate half-life, time period between substrate reinjections, and pore volumes of substrate solution injected. Using this tool, remediation-system designers can easily evaluate multiple alternatives to identify the most cost-effective design for their specific site.…”

“…where A is a is function of four dimensionless variables (C I /C MIN , PV, T T /T H , and T R /T H ). The coefficients C 1 to C 13 were differentiated in four groups based on interactions between design parameters (T T , T H , C I , and C MIN ) and well spacing (Borden et al, 2012). These regression equations have been incorporated into the SS Design Tool described in the next section.…”

“…Exhibit 6 illustrates the benefits of comparing several different alternatives to reduce costs and maximize contact efficiency. Detailed information on data entry and calibration procedures are provided in the design tool technical report (Borden et al, 2012).…”

“…Exhibit 1 provides information on where to download a simple, easy-to-use tool to aid in injection-system design. Borden et al (2012) conducted a series of numerical simulations to investigate the impact of different design parameters (Exhibit 2) on SS distribution in three dimensional, spatially heterogeneous aquifers. A portion of the aquifer was considered "contacted" if the SS concentration was greater than a user-specified minimum substrate concentration (C MIN ).…”
