Measurements of the depth of the water table and the concentration of soil gas radon at water wells in Virginia and Maryland show that at each well site, there is no correlation between the depths of the water table and the radon concentration. However, when comparing nearby water wells, there is a relationship between depth of the water table and the concentration of soil gas radon. Wells with a shallower water table tend to have less soil gas radon emanation. It may be that this relationship It may be that this relationship (higher water table with lower radon emanation) may explain seasonal changes in radon concentration, since changes in water table depth are caused by seasonal changes in precipitation.
对弗吉尼亚州和马里兰州水井的地下水位深度以及土壤气体氡浓度的测量表明，在每个水井位置，地下水位深度与氡浓度之间没有相关性。然而，在比较附近的水井时，地下水位深度与土壤气体氡浓度之间存在一种关系。地下水位较浅的水井往往土壤气体氡的散发量较少。可能这种关系（地下水位较高而氡散发量较低）可以解释氡浓度的季节性变化，因为地下水位深度的变化是由降水的季节性变化引起的。
