Water Quality Standards and Criteria Footnotes

U.S. national water quality criteria for protection of human health from consumption of aquatic organisms grown in the water body where the water itself is not consumed. This level for Dioxin (2,3,7,8-TCDD) is 5.1E-9 g/L

Footnote c:

This criterion is based on carcinogenicity of 10-6 risk. Alternate risk levels may be obtained by moving the decimal point (e.g., for a risk level of 10-5, move the decimal point in the recommended criterion one place to the right).
