Title from cover. Includes bibliographical references. "Guidelines for sediment cleanup continue to change. In general, early standards used chemical analyses. However, these guideline chemical concentrations were all based upon bioassays. Site specific guidelines are usually developed to address current action plans and realities of the site. In Hamilton Harbour, the development of a standard included chemical, biological and site-specific physical criteria. This standard has been attacked as being ultraconservative, i.e. a surgical strike; however, the cost of the smallest scientifically based cleanup is still very large"--Manuscript perspective.
