DeSimone, L.A., and Armstrong, D.S., 2022, Total and dissolved organic carbon data to support implementation of revised freshwater aluminum water-quality criteria in Massachusetts: U.S. Geological Survey data release,


This data set contains historical data on concentrations of total and dissolved organic carbon in Massachusetts streams from the U.S. Geological Survey National Water Information System (NWIS) database. The data were compiled from NWIS using site and sample selection criteria to retrieve all publicly available data from surface-water samples that contained analysis of both total and dissolved organic carbon. The data set was screened, as much as possible from the site and sample description information in NWIS, to retain only routine environmental samples from stream sites. The final data set consists of 223 samples from 52 sites and were collected from 1978 to 2007.

These data were compiled to examine the relation between concentrations of total and dissolved organic carbon in Massachusetts streams, for the purpose of estimating total or dissolved concentrations when data for only one of these constituents are available. The data set was compiled as part of a data collection effort by the U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, to support the implementation of site-dependent criteria for aluminum in Massachusetts surface waters.
