Title from cover. Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Two basic requirements, low bias and high precision, are necessary for generating reliable estimates for the load from point and nonpoint sources of pollution. Biases and low precision can be the result of using a bad sampling design and/or an inadequate method of estimation. The effects of biases can be reduced at the design stage prior to the data collection or at the data analysis stage. This paper discusses the statistical issues involved in generating adequate load estimations using recently published point source discharge data from the Niagara River to illustrate these issues"--Abstract.
