Results of the quarterly tritium survey of Four Mile Creek and its seeplines in the F- and H-Areas of SRS, June 1993

摘要

The Environmental Sciences Section (ESS) established a quarterly monitoring program of the Four Mile Creek seepline down gradient from the F- and H-Area seepage basins. The program surveys and tracks changes in tritium, specific conductivity, and pH for the seepline water. Measurements from the fifth quarterly survey (June 1993) showed lower tritium and conductivity measurements and higher pH values (pH 5--6) than measurements from previous studies. The results of the quarterly surveys suggest that infiltration of rainfall may be diluting and flushing the contaminants from the groundwater system. More measurements are needed to confirm these trends.
