Format

A data frame with 102 observations on the following 6 variables.

Date.On

Start of collection period. Date on which the sample bucket was installed on the collector.

Date.Off

End of collection period. Date on which the sample bucket was removed from the collector.

Week

a numeric vector indicating the cumulative week number starting from January 1, 2009.

NH4.Orig.mg.per.L

a character vector of the original NH_4 concentrations reported either as the observed value or less than some detection limit. For values reported as less than a detection limit, the value reported is the actual limit of detection or, in the case of a diluted sample, the product of the detection limit value and the dilution factor.

NH4.mg.per.L

a numeric vector of NH_4 concentrations with non-detects coded to their detection limit.

Censored

a logical vector indicating which observations are censored.
