CFCs also can be used to trace seepage from rivers into ground-water systems, provide diagnostic tools for detection and early warning of leakage from landfills and septic tanks, and to assess susceptibility of water-supply wells to contamination from near-surface sources. During the past 50 years, human activities have released an array of chemical and isotopic substances to the atmosphere. In the atmosphere, these substances have mixed and spread worldwide. Young ground water is typically found at depths from 0 to feet in unconsolidated sediments and at depths up to feet in fractured-rock systems. Shallow ground-water systems are commonly used for drinking water sources and they make up a large part of the baseflow in rivers and lakes.

Tritium 3 H or T is the radioactive isotope of hydrogen that decays with a half life of Tritium is produced naturally in the upper atmosphere by interaction of nitrogen, and, to a lesser extent, oxygen with cosmic rays. After oxidation to HTO, it takes part in the natural water cycle. These tests which were mainly performed in the early s, led to an increase of tritium in precipitation over the continents of the northern hemisphere from roughly 5 TU to levels of the order of TU. One TU Tritium Unit means a tritium to hydrogen ratio of 10
