 \section{Water Quality Portal Web Retrievals}
 \label{sec:usgsSTORET}
 %------------------------------------------------------------
-There are additional water quality data sets available from the Water Quality Data Portal (\url{http://www.waterqualitydata.us/}).  These data sets can be housed in either the STORET (data from EPA), NWIS database (data from USGS), STEWARDS database (USDA), and additional databases are slated to be included.  Because only USGS uses parameter codes, a \texttt{"}characteristic name\texttt{"} must be supplied.  The \texttt{getWQPqwData} function can take either a USGS parameter code, or a more general cahracteristic name in the parameterCd input argument. The Water Quality Data Portal includes data discovery tools and information on characteristic names. The following example retrieves specific conductance from a DNR site in Wisconsin.
