Estimation of toxic contaminant mean concentrations from stormwater quality data

A computer program, runmean (runoffmean), was developed for estimating toxic contaminant mean event concentrations in storm water runoff. For censored runoff concentration data, three estimation methods are used: a replacement method, a regression method, and a modified maximum likelihood method. An input file containing the commonly required information in runoff pollution studies is in a format used in most runoff concentration databases for …
