Water Quality Standards for Toxic Pollutants
DEQ is responsible for
establishing water quality criteria to protect human health. These criteria are established to allow Oregonians to consume fish
and shellfish and to use state waters for drinking water supply without
adverse health effects. DEQ’s current
standards are based on EPA recommended criteria. However, we are currently in the process of revising our criteria
based on the higher levels of fish consumed by many Oregonians. Please see below for additional information.

EQC Direction and Background
On October 23, 2008, the Oregon Environmental Quality Commission gave DEQ unanimous approval
to pursue rule revisions that will set new water quality
standards for toxic pollutants in Oregon. The new standards will be
based on a new fish consumption rate that is much more protective of
human health than the existing rate. In addition, DEQ is
reviewing the criteria for three naturally occurring earth metals: arsenic, iron and manganese.
The EQC directed DEQ to:
- Revise Oregon’s toxics criteria for human health based on a fish
consumption rate of 175 grams per person per day;
- Propose rule language that will allow DEQ to implement the
standards in National Pollutant Discharge Elimination System (NPDES)
permits and other Clean Water Act programs in an environmentally
meaningful and cost-effective manner;
- Propose rule language or develop other implementation strategies
to reduce the adverse impacts of toxic substances in Oregon’s waters
that are the result of non-point source (not via a pipe) discharges or other sources
not subject to section 402 of the Clean Water Act;
- Develop a proposed rule and implementation methods that
carefully consider the costs and benefits of the fish consumption
rate and the data and scientific analysis already compiled or that
is developed as part of the rulemaking proceeding.
For more information about the commission’s action, see DEQ’s news release.
Stakeholder Groups and Public Involvement
Oct. 2009: The Toxics Stakeholder Group has been updated to
assist DEQ in the development of a comprehensive
toxics reduction strategy.
