    dct:description "The data presented here are from hand held X-ray fluorescence measurements on wet and dry composite samples.  The composite samples are from 10 cm sections of sediment trenches in the Aztec Drinking Water Reservoir #1.  Samples were analyzed to evaluate chemistry of the reservoir sediments." ;
