Average concentration of constituents in groundwater samples at the Vienna Wells Site: Maries County, Missouri, 2013-2016

This dataset contains the groundwater data collected at the Vienna Wells Superfund site in Vienna, Missouri by the U.S. Geological Survey. Concentrations of tetrachloroethylene (PCE), trichloroethylene (TCE), and 1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113) are provided in micrograms per liter. A total of 56 groundwater samples were collected from monitoring wells on five separate occasions between July 2013 and April 2016. Concentrations are averages from each location over time. Note: A sample with a Depth_bott and Depth_top of 0 is a sample from a spring collected at the surface.
