Table 20 – Revised June 2010[date of EPA approval]

 

WATER QUALITY CRITERIA SUMMARY

(Applicable to all Basins)1

 

 

The concentration for each compound listed in this chart is a criteria or guidance value* not to be exceeded in waters of the state for the protection of aquatic life and human health. Specific descriptions of each compound and an explanation of values are included in Quality Criteria for Water (1986). Selecting values for regulatory purposes will depend on the most sensitive beneficial use to be protected, and what level of protection is necessary for aquatic life and human health.

 

This June 2010 table includes revisions DEQ adopted in 2004 and EPA approved June 1, 2010. This table therefore shows the effective criteria under state and federal law.

 

Note: The criteria revisions for arsenic shown in this table and adopted by the Environmental Quality Commission on April 21, 2011 are not applicable until they are approved by EPA Region 10. When they are approved and applicable a revised version of this table, including the date of EPA approval, will be posted on the DEQ Rules and Water Quality websites.

Footnotes:

H This value is based on a Drinking Water regulation.

J No bioconcentration factor was available; therefore, this value is based on that published in the 1986 EPA Gold Book.

K Human health criterion is for “dissolved” concentration based on the 1976 EPA Red Book conclusion that adverse effects from exposure at this level are aesthetic rather than toxic.

 

 

MEANING OF SYMBOLS:

 

 g  =  grams      M.C.L  =  Maximum Contaminant Level

 mg  =  milligrams      +  =  Hardness Dependent Criteria (100 mg/L used).

 ug  =  micrograms    *  =  Insufficient data to develop criteria; value presented is the L.O.E.L – Lower Observed Effect Level.

 ng  =  nanograms      **  =  Human health criteria for carcinogens reported for three risk levels. Value presented is the 10-6

               risk level,  which means the probability of one concern case per million people at the stated

               concentration.

 pg  =  picograms      ***  =  pH Dependent Criteria (7.8 pH used).

 f  =  fibers  

 Y  =  Yes  

 N  =  No
