INTRODUCTION
This digest is compiled to provide general information to the public as veil
as to Federal, State, and local officials. It contains excerpts from the
individual Federal-State vater quality standards establishing pollutant
specific criteria for interstate surface vaters. The vmter quality standards
program is implemented by the U. S. Environmental Protection Agency vhere
responsibility for providing vater quality recommendations, approving
State-adopted standards for interstate vaters, evaluating adherence 'to the
standards, and overseeing enforcement of standards compliance, has b««n
mandated by Congress.
Standards, a nationvide strategy for surface vater quality management, contain
three major elements: the use (recreation, drinking vater, fish and vildlife
propagation, industrial, or agricultural) to be made of the navigable vater;
criteria 1:0 protect these uses; and an an ti degradation statement to protect
existing high quality vaters, from degradation by the addition of pollutants.
Guidance Jior the development of standards by individual States is contained in
tvo EPA documents entitled ffater Quality Standards Handbook (1983) and Quality
Criteria for Water (1986).
Chromium is an element rarely found in natural vaters. It has oxidation
states ranging from Cr~ to Cr* , of vhich the trivalent form is most commonly
found in nature. Chrooium salts, primarily chromateat and dichromates, are
used extensively in metal finishing, textile, and leath«r tanning industries.
They are also used in pigments, fungicides, and vood pr*s«rvativ«s.
Chromium, has been shovn to be an essential trace element for humans even
though it has been shovn to be toxic in some instances. Chromium has been
found to produce toxic effects in aquatic life vfaon in relatively high
concentrations. ' .

Toxic substances narrative: Assigning concentration

beneficial use is very complex. Limits are generally
assigned based upon laboratory bioassay voric designed
to determine the 96-hour LC5Q for a. particular aquatic
species. There are s«v.§^l physical, chemical and
biological problems vhich arise vhen attempts are made
to develop vater quality standards based upon single
maximum concentration values. For this reason,
numerical concentration limits are developed in this
section for specified toxics. For toxics not
specified, or vhere data is not available in the
folloving table, concentrations for nonpersistent
toxic substances listed in Appendix C shall not exceed
0.1 of the 96-hour LC.. for sensitive indigenous
sp«cies> Concentrations of persistent toxicants
listed in Appendix C shall not exceed 0.05 of the
96-hour LC5Q for sensitive indigenous species.
Concentration! of bioaccumulative toxicants listed in
Appendix C shall not exceed 0.01 of the 96-hour LC
