Profile six Visible CFC recharge times required in the event that: (a) more youthful h2o from inside the harmony that have 1993 air offers that have water energized during the 1940; and you will (b) more youthful drinking water from inside the harmony that have 1993 sky combines having liquid charged within the 1975. Computations at 10°C and you will step 1 atm. total pressure.
Of the smooth and usually increasing character of your atmospheric blend percentages, hydrodynamic dispersion is not likely to have a serious affect CFC concentrations or visible CFC age in groundwater. Having fun with a-one-dimensional analytical solution to brand new advection-dispersion equation in steady state circulate career (van Genuchten and you can Alves, 1982), Plummer et al. (1993) simulated brand new transport and you can resulting decades concerns getting CFC-eleven and you can CFC-twelve having liquids recharged away from 1940 by way of 1991 (Shape 7). Read More
