TABLE 33C: Water Quality Guidance Values for Toxic Pollutants A

 

 

Water Quality Guidance Values Summary

 

The concentration for each compound listed in Table 33C is a guidance value that can be used in application of Oregon’s Toxic Substances Narrative (340-041-0033(2)) to waters of the state in order to protect aquatic life. All values are expressed as micrograms per liter (µg/L) except where noted. Compounds are listed in alphabetical order with the corresponding EPA number (from National Recommended Water Quality Criteria: 2002, EPA-822-R-02-047), corresponding Chemical Abstract Service (CAS) number, aquatic life freshwater acute and chronic guidance values, and aquatic life saltwater acute and chronic guidance values.

The following chemicals/compounds/classes are of concern due to the potential for toxic effects to aquatic organisms; however, no guidance values are designated. If these compounds are identified in the waste stream, then a review of the scientific literature may be appropriate for deriving guidance values.

 

Polybrominated diphenyl ethers (PBDE)

Polybrominated biphenyls (PBB)

Pharmaceuticals

Personal care products

Alkyl Phenols

Other chemicals with Toxic effects

 

 

Footnotes:

A  Values in Table 33C are applicable to all basins.

B  This number was assigned to the list of non-priority pollutants in National Recommended Water Quality Criteria: 2002 (EPA-822-R-02-047).

Similar comment, why include a guidance value when there are aquatic life & human health criteria

Lori Pillsbury, 2013-07-25T13:27:00Z
same

Lori Pillsbury, 2013-07-25T13:26:00Z
Why are these included still as a guidance value when there is an aquatic life criteria for DDT (expressed as total so it would include these even if this is the only species measured?
