Multiple tracer study in Horonobe, northern Hokkaido, Japan: 2. Depletion of chlorofluorocarbons (CFCs) estimated using 3H/3He index and lumped parameter models
Description: The conservativeness of chlorofluorocarbons (CFC-12, CFC-11, and CFC-113) in an environment rich in organic carbon was evaluated using multiple tracer analyses and lumped parameter models (LPMs). Wells on a coastal plain in Horonobe, northern Hokkaido, Japan, were studied. The CFC concentrations in groundwater from 22 wells were measured, converted into atmospheric mixing ratios (CARs), and compared with estimated ratios (EARs) obtained from 3H/3He values and LPMs. [Source: Journal of Hydrology]
