چکیده انگلیسی
In most cases, based on the presence of detectable levels of tritium throughout most of the aquifer, the groundwater in the coastal aquifer was determined to contain a young component with a transit time of less than forty years. However, the 14C levels of most of the same groundwater samples were found to be lower than atmospheric levels (34-102 vs. >100Â pMC), probably due to water-rock interactions rather than decay due to old age. Some older waters exist in the lower sub-aquifers of the deeper wells (120-140Â m) where both lower 14C values (42-69Â pMC) and very low levels of tritium were found (0.1-0.7Â TU).
