It contains excerpts from the individual Federal-State water quality standards establishing pollutant specific criteria for interstate surface waters. The vater quality standards program, is implemented by the U. S. Environmental Protection Agency where responsibility for providing water quality recommendations, approving State-adopted standards for interstate waters, evaluating adherence to the standards, and overseeing enforcement of standards compliance, has been mandated by Congress. Standards, a nationwide strategy for surface water quality management, contain three major elements: the use (recreation, drinking water, fish and wildlife propagation, industrial, or agricultural) to be made of the navigable water; criteria to protect these uses; and an antidegradation statement to protect existing high quality waters, from degradation by the addition of pollutants. Guidance for the development of standards by individual States is contained in two EPA documents entitled Vater Quality Standards Handbook (1983) and Quality Criteria for Vater (1986). This digest summarized three organic compounds which are usually incorporated into State Vater Quality Standards. They are: phenol, phthalate esters, and polychlorinated biphenyls(PCB's). Phenol and phenolic compounds are present in waters receiving wastes resulting from wood and coal distillation, oil refining, chemicals production and the natural degradation.of organic wastes. phthalate esters are not known to be naturally occurring. Their presence in water systems is a result of their production for use in plastics and to a limited extent pesticides. Likewise, PCB's are not naturally occurring. their presence in water has been of particular importance because of toxic effects associated with very minute quantities of the chemical, and because it is a suspected carcinogen. PCB has, in the past, been primarily used as a heat exchanger in electrical capacitors and transformers. The production of PCB's for this use has been greatly reduced. EPA has established a zero discharge PCB federal effluent standard for new and existing production facilities (40 CFR 129.105). The presence of PCB's in water is primarily a result of spills and uncontrollable non-point source leaching. All three substances exert detrimental effects on aquatic and animal life. for these reasons EPA has established water quality criteria recommendations for the chemicals in its publication, Quality Criteria for Vater (1986). The criteria are as follows: Phenol freshwater aquatic life; 10,200 ug/1 acute 2,560 ug/1 chronic saltwater aquatic life; 5,800 ug/1 acute human health; 3.5 mg/1 to protect public health -2- ------- Phthalate Esters Polychlorinated Biphenyls 0.3 mg/1 to control undesirable taste and odor Verified Reference Dose (RfD) of 0.1 mg/kg/day freshwater aquatic life; 940 ug/1 acute 3 ug/1 chronic « saltwater aquatic life; 2,944 ug/1 acute human health; dimethyl phthalate 313 mg/1 vater and contaminated aquatic organism ingestion 2.9 g/1 contaminated aquatic organism ingestion only diethyl phthalate 350 mg/1 vater and contaminated aquatic organism ingestion 1.8 g/1 contaminated aquatic organism ingestion only dibutyl phthalate 34 mg/1 vater and contaminated aquatic organism ingestion 154 mg/1 contaminated aquatic organism ingestion only di-2-ethylhexyl phthalate 15 mg/1 vater and contaminated aquatic organism ingestion 50 mg/1 contaminated aquatic organism ingestion only freshvater aquatic life; ^ 0.014 ug/1 (chronic) as a 24-hour average 2.0 ug/1 acute saltwater aquatic life; ^ 0.030 ug/1 (chronic) as a 24-hour average 10 ug/1 acute human health; 0.079 ng/1 vater and aquatic organism consumption 0.79 ng/1 aquatic organism consumption only ** Probably too high because it is based on bioconcentration factors measured in laboratory studies, but field studies apparently produce factors at least 10 times higher for fishes. j, -^ For the maximum protection of human health from the potential carcinogenic effects of exposure to polychlorinated biphenyls through the ingestion of contaminated vater and contaminated aquatic organisms, the ambient vater concentration should be zero, based on the nonthreshold assumption for this chemical. However, zero level may not be attainable at the present time. Since vater quality standards experience revisions and upgrading from time to -3- ------- time, following procedures set forth in the Clean Water Act, individual entries in this digest may be superseded. As these revisions are accomplished and allowing for the States to revise their standards accordingly, this digest vill be updated and reissued. Because this publication is not intended for use other than as a general information resource, to obtain the latest information and for special purposes and applications, the reader needs to refer to the current approved water quality standards. These can be obtained from the State water pollution control agencies or the EPA or Regional Offices. -4- ------- REFERENCES 3 Water Quality Boundaries and Standards (Arizona), Article 2.
