TABLE 40: Human Health Criteria for Toxic Pollutants

DRAFT

 

Note: The Environmental Quality Commission adopted the following criteria on XXXX. The criteria are effective for Clean Water Act purposes only after EPA approval.

 

Human Health Criteria Summary

A human health criterion is the highest concentration of a pollutant in water that is not expected to pose a significant risk to human health. The concentration for each pollutant listed in Table 40 is a criterion not to be exceeded in waters of the state in order to protect human health. Values in Table 40 are applicable to all basins, and are expressed as micrograms per liter (µg/L). Pollutants are listed in alphabetical order with the corresponding Chemical Abstract Service (CAS) number, indication of whether the pollutant is categorized as a carcinogen (can cause cancer in humans), or if there is an associated aquatic life criterion (i.e. “y”= yes, “n” = no). The “water + organism” criteria refer to safe limits that have been established for the consumption of drinking water and fish, including shellfish. The “organism only” criteria refer to safe limits that have been established for the consumption of fish and shellfish only. All the human health criteria were calculated using a fish consumption rate of 175 grams per day, which is approximately equal to 23 8-ounce fish meals per month. For pollutants categorized as carcinogens, values represent a cancer risk of one additional case of cancer in one million people (i.e. 10-6), unless otherwise noted. In addition, analysis for all pollutants is for total of all forms and species of that pollutant, unless otherwise noted.

This is still a working draft of the criteria table. Footnotes, blanks, language, etc. need to be further verified.
