1 The in-stream criterion is expressed in terms of the dissolved fraction in the water column. Conversion factors used to calculate dissolved criteria are found in the EPA document - National Recommended Water Quality Criteria - EPA 2006.
2 The in-stream criterion is lower than the EPD laboratory detection limits (A "*" indicates that the criterion may be higher than or lower than EPD laboratory detection limits depending upon the hardness of the water).
3 The freshwater aquatic life criteria for these metals are expressed as a function of total hardness (mg/L) in a water body and a water effect ratio (WER). Values in the table above assume a hardness of 50 mg/L CaCO3 and a WER of 1. For other hardness values, the following equations from the EPA document - National Recommended Water Quality Criteria - EPA 2006 should be used. For site-specific criteria with WER values other than 1, see 391-3-6-.03(18)(b).
4 This pollutant is addressed in 391-3-6-.06.
5 For applicable site-specific criteria, see 391-3-6-.03(18)(a).
