1,2,3,4-Tetrachlorobenzene Concentrations from 1994 USEPA Guidance Document
Description
1,2,3,4-Tetrachlorobenzene (TcCB) concentrations (ppb) in soil samples at a
reference area and a cleanup area. There are 47 observations for the reference area
and 77 for the cleanup area. There is only one nondetect in the dataset (it's in the
cleanup area), and it is reported as ND. Here it is assumed the nondetect is
less than the smallest reported value, which is 0.09 ppb. Note that on page 6.23 of
USEPA (1994b), a value of 25.5 for the Cleanup Unit was erroneously omitted.
Usage
EPA.94b.tccb.df
Format
A data frame with 124 observations on the following 4 variables.
TcCB.origa character vector with the original tetrachlorobenzene concentrations (ppb)
TcCBa numeric vector of tetrachlorobenzene with <0.99 coded as 0.99
Censoreda logical vector indicating which observations are censored
Areaa factor indicating the area (cleanup vs. reference)
