Contaminated sediment definition

Contaminated sediment means sediment that is contaminated as determined by the concentrations of the contaminants, actual circumstances of exposure, biological diversity studies, toxicity testing, or other evidence of harmful effects, as applicable. [Refer to the sediment guidelines referenced in subsections 62-780.100(1) and (6), F.A.C., for guidance on the evaluation of contaminant concentrations, sediment quality conditions, and testing methods.]

Contaminated sediment means sediment that contains a hazardous substance.

Contaminated sediment means surface sediments designated under the procedures of WAC 173-204-310 as exceeding the applicable sediment quality standards of WAC 173-204-320 through 173-204-340.

Examples of Contaminated sediment in a sentence

• Recommendation 11: Contaminated sediment leads to the uptake of some Level I substances - in particular, mercury, PCBs, and pesticides -- by fish, wildlife and, ultimately, humans.

• Contaminated sediment issues, such as what ecological risk assessment values should be used and what are the options for completing these risk assessments, have become increasingly important as the Department and the EPA begin work on the Portland Harbor Superfund Site.

• Contaminated sediment sites often involve difficult technical and social issues.

• Contaminated sediment issues, such as what ecological risk assessment values should be used and what are the options for completing these risk assessments, have become increasingly important as DEQ and the EPA continue work on the Portland Harbor Superfund site.

• Contaminated sediment guidelinesThe U.S. Environmental Protection Agency (EPA) has prepared technical guidance to address the exposure of sediment-dwelling organisms to contaminants that tend to partition into aquatic sediments (U.S. EPA 2000 a, b, c, d).

Contaminated sediment means sediment that contains a hazardous substance. [Wis. Stat. § 292.01(1s)]

Contaminated sediment means surface sediments exceeding the applicable sediment quality standards in WAC 173-204-320 through 173-204-340 or the applicable sediment cleanup standards in WAC 173-204-560.

Contaminated sediment means sediment that is contaminated with petroleum or petroleum products or their chemical constituents as determined by the concentrations of the petroleum or petroleum products’ contaminants of concern, actual circumstances of exposure, biological diversity studies, toxicity testing, or other evidence of harmful effects, as applicable. [Refer to the sediment guidelines referenced in subsection 62-770.140(2), F.A.C. for guidance on the evaluation of concentrations of petroleum products’ contaminants of concern, sediment quality conditions, and testing methods.]

Contaminated sediment means sediment that is contaminated with petroleum or petroleum products or their chemical constituents to the extent that contamination may be harmful to human health or the environment result in an adverse human health or biological effect as determined by the concentrations of the petroleum or petroleum products’ contaminants chemicals of concern, actual circumstances of exposure, diversity studies, or toxicity testing or other evidence of harmful effects, as applicable. (Refer to the Development and Evaluation of Sediment Quality Assessment Guidelines, Volumes 1-4, dated November 1994, for guidance on the evaluation of concentrations of petroleum products’ contaminants of concern and sediment quality conditions.)
