Description

Imports data from the Water Quality Portal, so it could be STORET, USGS, or USDA data. This function gets the data from: https://www.waterqualitydata.us For raw data, use readWQPdata. This function will retrieve the raw data, and compress it (summing constituents). See chapter 7 of the EGRET user guide for more details, then converts it to the Sample dataframe structure.
