This document is also available in pdf format: fs Information about the age of ground water can be used to define recharge rates, refine hydrologic models of ground-water systems, predict contamination potential, and estimate the time needed to flush contaminants from ground-water systems. 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.

Dating groundwater

An effective integrator of hydrologic history, isotope hydrology is a key to understanding fundamental physical, chemical, biological, and climate forcing processes occurring in a watershed. T he measurement of the concentrations of isotopes in groundwater and surface water can be incorporated into models to predict future responses of the watershed to trends in land-use change, water resource management decisions, and climate variability. Isotope methods are useful in regions where more traditional hydrologic tools such as geologic mapping of aquifer material, piezometric data, pump tests, hydraulic conductivity measurements, major ion chemistry, and hydrologic models give ambiguous results or insufficient information. Isotopes can be used to efficiently unravel water sources that have combined at the sampling location, and they can accurately determine residence time information, which has important implications for water resources management. If a major urban drinking water supply well from a Southwest basin pumps thousand-yearold water, for example, then it is mining the groundwater resource at a much faster rate than natural recharge.
