Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Summer Research
This project seeks to characterize the chemical and isotopic compositions of groundwater and surface water in portions of Pierce and King Counties, with the goal of using these results to determine the water sources of local lakes. Specifically of interest are lakes studied by Puget Sound students over the past ~10 years where water analyses appear to define a mixing line, likely between surface runoff and the shallow groundwater (Figures 1, 2, and 3). Existing data pertain only to surface water from the lakes while data pertaining to groundwater is patchy or nonexistent and includes only a few of the …
