# TABLE 4 0 : Human Health Water Quality Criteria for Toxic Pollutants

Effective October 17, 2011

Human Health Criteria Summary

The concentration for each pollutant listed in Table 40 was derived to protect Oregonians from potential

adverse health impacts associated with long

- term exposure to toxic substances associated with consumption

of fish, shellfish, and water. The “organism only” criteria are established to protect fish and shellfish

consumption and apply to waters of the state designated for fishi ng. The “water + organism” criteria are

established to protect the consumption of drinking water, fish, and shellfish, and apply where both fishing and

domestic water supply (public and private) are designated uses. All criteria are expressed as microgra ms per

liter (μg/L), unless otherwise noted. Pollutants are listed in alphabetical order. Additional information includes

the Chemical Abstract Service (CAS) number, whether the criterion is based on carcinogenic effects (can

cause cancer in humans), and whether there is an aquatic life criterion for the pollutant (i.e. “y”= yes, “n” = no).

All the human health criteria were calculated using a fish consumption rate of 175 grams per day unless

otherwise noted. A fish consumption rate of 175 grams per day 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. All metals criteria are for total metal

concentration, unless otherwise noted. Italicized pollutants represent non

- priority pollutants

. The human

health criteria revisions established by OAR 340

- 041

- 0033 and shown in Table 40 do not become applicable

for purposes of ORS chapter 468 B or the federal Clean Water Act until approved by EPA pursuant to 40 CFR

131.21 (4/27/2000).
