* WATER QUALITY STANDARDS CRITERIA DIGEST A COMPILATION OF FEDERAL/STATE CRITERIA ON -RADIATION- ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. AUGUST 1972 ------- INTRODUCTION This digest was compiled in order to provide general information to the public as well as to Federal, State, and local officials. It contains excerpts from the individual Federal-State water quality standards establishing radio- logical criteria for interstate waters. The water quality standards program is directed by the Environmental Protection Agency, an independent regulatory agency which has responsibility for approving State-adopted standards for interstate waters, evaluating adherence to the standards, and overseeing enforcement of stan- dards compliance. Standards, the first nationwide strategy for water quality management, con- tain four major elements: the use (recreation, drinking water, fish and wildlife propagation, industrial, or agricultural) to be made of the interstate waters; criteria to protect those uses; implementation plans (for needed industrial- municipal waste treatment improvements, among others) and enforcement plans; and an antidegradation statement to protect existing high quality waters. Minimum water quality criteria, or numerical specificationsof physical, chemical, temperature, and biological levels, are stated in the National Techni- cal Advisory Committee report to the Secretary of the Interior, Water Quality Criteria, dated April 1, 1968, and published by the Government Printing Office, Washington, B.C. Unavailability of the NTAC report before June 30, 1967--the date set by the Water Quality Act of 1965 for formal adoption of State standards-- resulted in significant variations between the state-adopted and the NTAC minimum criteria. Some standards were adopted and approved before the NTAC report.became available. Also, the Water Quality Criteria report is subject to updating in light of new scientific and technical information. Since radioactive materials such as radium, strontium 90, and tritium, are toxic to man as well as being cumulative in his system, these pollutants are subject to control, monitoring, and measurement whatever the contact medium. The total radiation in an individual's environment--his job and medical treat- ments, the food and water he consumes, and air he breathes—must be considered. Radiation enters our environment from various sources: mining and processing of radioactive ores; nuclear weapons testing fallout; power reactor emissions; and medical, research, and industrial applications, as well as natural emissions from stellar bodies and geological deposits. The EPA-recommended criteria limits on these materials in water are: Gross Beta 500 pc/1 (picocuries per liter) Radium 1.0 pc/1 Strontium-90 10.0 pc/1 Tritium 3000.0 pc/1 These criteria essentially duplicate or parallel the recommended limits in the U.S. Public Health Service Drinking Water Standards, cited by the NTAC report, Water Quality Criteria. Since water quality standards experience revisions and upgrading fron time to time, following procedures set forth in the Federal Water Pollution Control Act, individual entries in this digest may be superseded. As these revisions are accomplished, this digest will be updated and reissued. Because this publication is not intended for use other than as a general information resource, for the latest information, and for special purposes and applications, refer to the existing approved water quality standards which can be obtained from the State water pollution control agencies or EPA Washington, D.C. or regional offices. Individual State-adopted criteria follow. ------- KEY PWS , Public Water Supply F§WL Fish and Wildlife Agr. Agricultural Ind. Industrial MPCw Maximum Permissible Concentration per week pc/1 § pCi/1 Picocuries per liter USPHS U.S. Public Health Service (For explanation of use classifications, see EPA publication, "General Stream Use Designations.") ------- RADIATION CRITERIA Alabama Alaska Arizona Arkansas California (1) Public Water Supply. No radionuclide or mixture of radionuclides shall be present at concentrations greater than those specified by the EPA (USPHS) drinking water standards. (2) Other Uses. The concentrations of radioactive materials present shall not exceed the radiation protection guides recommended by the Criteria and Standards Division, Office of Radiation Protection, EPA (formerly Federal Radiation Council). Conform with current USPHS drinking water standards. The concentration of radioactivity in the surface waters of the state shall not: a. Exceed l/30th of theMPCw values given for continuous occupational exposure in National Bureau of Standards handbook No. 69. b. Exceed the Public Health Service Drinking water standards for waters used for domestic supplies. c. Result in the accumulation of radioactivity in edible plants or animals that present a hazard to consumers. d. Be harmful to aquatic life. The Rules and Regulations for the Control of Sources of Ionizing Radiation, of the Division of Radiological Health, Arkansas State Board of Health, shall apply as to the limits established for radiation levels in un- controlled areas. None present in concentrations exceeding levels set forth in California Radiation Control Regulations, Subchapter 4, Chapter 5, Title 17, California Admin- istrative Code at any place. Some variation in this statement was.-adopted by the 32 regional water quality boards, 1. As proposed by EPA in the Federal Register, March 11, ]972. ------- Colorado Connecticut Delaware Florida Georgia Hawaii Radioactive materials attributable to municipal, industrial or other controllable sources will be minimum concentrations that are physically and economically feasible to achieve. In no case shall such materials in the stream exceed the limits established in the current edition of the U.S. Public Health Service Drinking Water Standards or the limits approved by the Federal Radiation Council, or, in the absence of any limits specified by the U.S. Public Health Service or the Federal Radiation Council, 1/30 of the 168-hour-week values for other radioactive substances specified in the National Bureau of Standards Handbook 69. Alpha emitters 3 pc/1 Beta emitters 1000 pc/1 Also USPHS Drinking Water Standards Alpha emitters 3 pc/1 Beta emitters 1000 pc/1 Gross Beta Activity - (in known absence of Strontium-90 and alpha emitters), not to exceed one thousand micro- microcuries at any time. The maximum permissable concentrations of radionuclides in the waters of the state must conform to the limits which are cited in Chapter 270-5-20 "Control of Radio- active Materials" of the Rules and Regulations of the Georgia Department of Public Health. The concentrations of radioactivity in water shall not exceed l/30th of the MPCw values given for continuous occupational exposure in National Bureau of Standards Handbook No. 69. No radionuclides or mixture of radio- nuclides shall be present at concentrations greater than those specified by the U.S. Public Health Service, Pub- lication No. 956, as revised in 1962, as acceptable for drinking water. The concentration of radioactive materials present in fresh, estuarine, and marine waters shall be less than those that would require restrictions on the use of organisms harvested from the area in order to meet the Radiation Protection Guides recommended by the Federal Radiation Council. These water quality criteria are based upon the best currently available data. It is possible that studies planned to be made in connection with the implementation program may prove them to be either inadequate or un- attainable. For this reason, they will be subject to periodic review and, where necessary, to change. Any ------- Idaho Illinois Indiana Iowa Kansas Kentucky change will be made only after public hearing, held in compliance with the Hawaii Administrative Procedure Act and the Rules of Practice and Procedure of the Department of Health. Radioactive materials of other than natural origin shall not be present in any amount which reflects failure in any case to apply all controls which are physically or economically feasible. In no case shall such materials exceed the limits established in the 1962 USPHS.Drinking Water Standards.
