There are also several useful attributes attached to the data frame:
\tabular{lll}{
Name \tab Type \tab Description \cr
url \tab character \tab The url used to generate the data \cr

}
Imports data from the Water Quality Portal.
This function gets the data from here: \url{http://www.waterqualitydata.us}. There
are four required input arguments: siteNumber, parameterCd, startDate, and endDate.
parameterCd can either be a USGS 5-digit code, or a characteristic name. The sites can be
either USGS, or other Water Quality Portal offered sites. It is required to use the 'full'
site name, such as 'USGS-01234567'.
