C. 20003 Contract Number 68-01-6058 Project Number WA-80-A055 ------- ------- Introduction This digest was compiled to provide general information to the public as well as to Federal, State, and local officials. It contains excerpts from the individual State-Federal water quality standards establishing pollutant specific criteria for navigable surface waters. The water quality standards program is implemented by the U.S. Environmental Protection Agency where responsibility for providing water quality recommendations, approving State-adopted standards for navigable waters, evaluating adherence to the standards, and overseeing enforcement of standards compliance, has been mandated by Congress. The standards program, a nationwide strategy for surface water quality management, contains two major elements: the use (recreation, drinking water, fish and wildlife propagation, industrial, or agricultural) to be made of the navigable water; and criteria to protect these uses. Water quality criteria (numerical or narrative specifications for physical, chemical, temperature, and biological constituents are stated in the July 1976 U.S. Environmental Protection Agency publication Quality Criteria for Water (QCW), order # 055-001-01049-4, price $3.50, available from the Government Printing Office, Washington, D.C. The 1976 QCW, commonly referred to as the "Red Book," is the most current compilation of scientific information used by the Agency as a basis for assessing water quality. This publication is subject to periodic updating and revisions in light of new scientific and technical information. Chromium is an elementjrarely found in natural waters. It has oxidation states ranging from Cr to Cr , of which the trivalent form is most commonly found in nature. Chromium salts, primarily chromates and dichromates, are used extensively in metal finishing, textile, and leather tanning industries. They are also used in pigments, fungicides, and wood preservatives. Chromium has been shown to be an essential trace element for humans even though it has been shown to be toxic in some instances. Chromium has been found to produce toxic effects in aquatic life when in relatively high concentrations. The 1976 Quality Criteria for Water recommends the following: 50 ugA (total) for domestic water supply (health) 100 ug/1 (total) for freshwater aquatic life. Since water quality standards are revised from time to time, following procedures set forth in the Clean Water Act, individual entries in this digest may be superseded. This digest will be updated periodically. Because this publication is intended for use only as a general information reference, the reader needs to refer to the current approved water quality standards to obtain the latest information for special purposes and applications. These can be obtained from the State water pollution control agencies or the EPA Regional Offices. ------- REFERENCES California Water Quality Standards by River Basins, c.a. 1975 For more detailed information on selected basins, sub-basins and stretches of streams and coastal areas refer to California State Water Quality Standards. n Delaware Water Quality Standards, March 25, 1979 Q Idaho Water Quality Standards, c.a.
