Quarterly sampling of the wetlands along the old F Area effluent ditch: August 1994

PDF Version Also Available for Download.

Description

In August 1994, well point water and near-surface water samples were collected to characterize tritium and volatile organic compounds (VOC) in the wetlands along the old F-Area effluent ditch south of 643-E (old burial ground). The August sampling event was the third in a series of eight events. Groundwater flow paths suggest that compounds detected in water table wells around 643-E migrate towards the old F-Area effluent ditch and Fourmile Branch. Recent analytical results from well point and near-surface water sampling in the wetlands that comprise the old F-Area effluent ditch have shown that tritium and small quantities of VOCs ... continued below

Description

In August 1994, well point water and near-surface water samples were collected to characterize tritium and volatile organic compounds (VOC) in the wetlands along the old F-Area effluent ditch south of 643-E (old burial ground). The August sampling event was the third in a series of eight events. Groundwater flow paths suggest that compounds detected in water table wells around 643-E migrate towards the old F-Area effluent ditch and Fourmile Branch. Recent analytical results from well point and near-surface water sampling in the wetlands that comprise the old F-Area effluent ditch have shown that tritium and small quantities of VOCs are outcropping in the area. For this study, seven locations along the old F-Area effluent ditch were selected to be sampled. Well point samples were collected from all seven locations and near-surface water samples were collected at four locations. A secondary objective of this project was to compare VOC concentrations between the well points installed to depths of 6 to 8 ft and the near-surface water sampling buckets installed to depths of 1 to 2 ft. Based on differences in tritium concentrations at each location, it was determined that the sampling devices intercepted different groundwater flow paths. This negated direct comparison of analytical results between devices. However, when VOC concentrations measured at each well point and bucket location were normalized, based on the percent differences observed in tritium concentrations at that location, the resulting well point and bucket VOC concentrations were comparable in most cases. These results are consistent with the results from the three previous sampling events, and suggest that volatilization losses of VOCs from the buckets may be negligible. Since the results from the two sampling methodologies are not directly comparable, further sampling of the buckets is not planned.
