Processing of Water Quality Data

Processes water quality data. This function looks at detection limit and detection conditions to determine if a value is left censored or not. Censored values are given the qualifier "<". The dataframe is also converted from a long to wide format.

Usage

processQWData(data)

Arguments

data

dataframe from Water Quality Portal

Value

data dataframe with first column dateTime, and at least one qualifier and value columns (subsequent qualifier/value columns could follow depending on the number of parameter codes)
