- Suppose A Spill Of 1 M Of Pure Tce Dnapl Specific Density 1 47 G Cm Creates An Approximately Rectangular Contamina 1 (58.26 KiB) Viewed 26 times
Suppose a spill of 1 m³ of pure TCE DNAPL (specific density = 1.47 g/cm³) creates an approximately rectangular contaminated groundwater plume that is 120 m long, 32 m wide and 6.3 m deep. The formation has a hydraulic gradient of 0.0015, a hydraulic conductivity of 0.0005 m/s, a porosity of 0.32 and the direction of groundwater flow is through the small end of the plume. The average dissolved TCE concentration measured at the end of the plume where the extraction wells will be placed is 2.2 ppm. If pump and treat was used to remediate this plume (assuming constant conditions over time, local TCE sorption equilibrium, and pumping occurring at the speed of the natural groundwater flow), approximately how many years would it take to completely treat the TCE in the groundwater?
