Concentrations of tetrachloroethylene in tree-core and passive soil-gas samples and interpolated tetrachloroethylene soil data at the Vienna Wells site, Maries County, Missouri, 2011-2016

This U.S. Geological Survey (USGS) Data Release contains tree-core, soil-gas, and soil data collected at the Vienna Wells Superfund site in Vienna, Missouri by the U.S. Geological Survey between 2011 and 2016. Concentrations of tetrachloroethylene (PCE) are reported for each sample in each medium. Tree-core sampling was conducted over two days (July 29, 2014 and May 21, 2015). Trees sampled on July 29, 2014 were used to calculate concentration centroids for each tree to compare with concentration centroids in soil samples. Tree 29 was sampled on May 21, 2015 to characterize and model tetrachloroethylene concentrations within a single tree. An interpolated soil surface was created from 1,016 soil samples (see doi: 10.5066/F71835D8 for raw soil dataset) and sampled at 1-m intervals 50 meters from each tree to create the interpolated soil dataset here. To characterize subsurface concentrations of PCE around tree 29, equilibrium passive samplers were deployed from July 2015 to May 2016.
