Oahu {NADA}

Arsenic concentrations in Manoa Stream, Oahu Hawaii

Description

Arsenic concentrations (ug/L) in an urban stream, Manoa Stream at Kanewai Field, on Oahu, Hawaii.

Objective is to characterize conditions by computing summary statistics.

There are three detection limits, at 0.9, 1, and 2 ug/L. Uncensored values reported below the lowest detection limit indicate that informative censoring may have been used, and so the results are likely biased high. Used in Chapter 6 of the NADA book.
