Guidelines for deriving numerical criteria
- Guidelines for Deriving Numerical National Water Quality Criteria for the Protection of Aquatic Organisms and Their Uses (1985 Guidelines) (PDF) (104 pp., 3.3 MB) | Please email us for a Section 508 accessible copy.
EPA Science Advisory Board Activies Related to Guidelines Revisions
- Draft Strategy: Proposed Revisions (PDF) (5 pp., 74 K) (February 6, 2003)
We established a guidelines revision workgroup to identify, evaluate, and revise the existing guidelines. - Contaminants of Emerging Concern, including pharmaceuticals and personal care products
Finalized criteria
- Current Criteria Table containing aquatic life criteria for pollutants.
- Ammonia (Update, December 1999)
- Cadmium
- Copper
- Diazinon
- Dissolved Oxygen
- Methyl Tertiary-Butyl Ether (MTBE)
- Nonylphenol
- Tributyltin
- Chemical specific criteria documents from the 1980's
Criteria under development
EPA is revising the current aquatic life criteria for lead, silver, and selenium, re-evaluating the current aquatic life criteria for ammonia, and developing new aquatic life criteria for atrazine.
