Tetrachloroethylene (C Cls) also known as PCE, is a solvent that was used extensively in the past to remove grease from metal machine parts. PCE wastes were often disposed in open seepage basins. Consider an industrial site in which the PCE concentration in soil below an old seepage basin is 655 mg(c)/kg(s). The PCE is degraded by naturally occurring bacteria at the site, and the process can be approximately as first order with a 1-yr half-life. 5. a. Calculate the...
