Figure 5. Argon and nitrogen gas concentrations in ground water and their theoretical values assuming air-saturated water equilibrium at 420-m elevation and temperatures ranging from 0 degrees to 20 degrees C. [Horizontal tic marks on the equilibrium line indicate Ar and N₂ equilibrium concentrations from 0 degrees to 20 degrees C in 2-degree increments.]
