Concentration data on up to 91 individual constituents in USGS DTS‐1, G‐1, PCC‐1, and W‐1 have been collected from 1647 journal articles and technical reports. These data are summarized in consensus (mean) values with uncertainties expressed as one standard deviation. Mean values are also calculated as a function of analytical procedure and all raw data are given in the tables. Recommended values are proposed based upon data criteria used by NIST (National Institute of Standards and Technology, formerly the National Bureau of Standrds or NBS).
