Tritium as a Ground Water Tracer

Tritium in form of tritiated water is nearly perfect ground water tracer; its disadvantage lies in its radioactive properties and effects on public health; comparison of risks and benefits; evaluation of possible public health hazards and permissible concentrations of tritium in water; it is concluded that in case of aquifer recharge with waste waters in Los Angeles County mentioned as example, proposed study by use of tritium as tracer would be justified.
