    dct:description "This data set summarizes the results from water and sediment samples collected from wetlands near decommissioned petroleum wells throughout the Texas Gulf Coast in order to determine the presence of constituents related to petroleum production. Site selection and sample collection occurred during an approximate 9 month period from September 2015 to May 2016.  The data set includes two tables: one contains sediment-quality results and the other contains water-quality results." ;
