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 vater- 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
standard:!, and overseeing enforcement of standards compliance has been
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 to protect these uses; and an antidegradation statement to protect
existing high quality vaters,, from degradation by the addition of pollutants.
Guidance for the development of standards by individual States is contained in
tvo EPA documents entitled Vater Quality Standards Handbook. (1983) and Quality
Criteria for Vater (1986). '— ~ "-— L
Arsenic is an element possessing both metallic and non-metallic properties.
It exists in both "trivalent and pentavalent states and compounds containing
arsenic can be organic as veil as inorganic. The trivalent inorganic species
are the more toxic forms of arsenic, though most forms are toxic to some
degree in mammals as veil as aquatic life.
Arsenic has been found in unpolluted vaters. Hovever, it is present in most
vaters because of its use in a vide range of industries including herbicides,
paint pigments, copper and lead alloys, glass and electrical semiconductors.
The 1986 Quality Criteria for Vater recommends the relieving:
Freshwater Aquatic Organisms and Their Uses:
Arsenic(III)
acute 360 ug/1
chronic 190 ug/1
Saltvater Aquatic Organisms and Their Uses:
acute 69 ug/1
chronic 36 ug/1
Human Health: ' •
2.2 ng/1 vater and fish ingestion
17.5 ng/1 fish consumption only
(calculated according to certain risk level)
Since vater quality standards are revised from 'time to time, folloving
procedures set forth in the Clean Vater Act, individual entries in this digest
may be superseded. This digest vill be updated periodically. Because this

publication is intended .for use only as a general information reference, the

vith this objective will be determined by use of
