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
(J.S. Environmental Protection Agency where responsibil ity 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 publi-
cation 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, corranonly 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.
Although natural waters contain dissolved solids, the subject of this
digest, consisting mainly of carbonates, bicarbonates, chlorides,
sulfates, phosphates, and possibly nitrates with traces of metallic
elements, increases in these substances above normal are undesirable
and sometimes detrimental. Concentrations or effects of these
substances can be raised or synergistically altered by, for example,
the addition of chemical wastes, dissolved salts, acids, alkalis, gas
and oil-well brines, or irrigation drainage. Adverse effects may be
unpalatable drinking water, fish kills, crop damage, or corrosion
damage in water systems.
The 1976 Quality Criteria for Water recommends a criterion of 250
mg/1 for chlorides and sulfates in domestic water supplies (welfare).
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entries in this digest may be superseded.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.

This presents specific numeric objectives which apply to all waters of
the Sacramento-San Joaquin Delta. All waters lying within the legal
boundaries of the Deita are covered by these objectives unless
otherwise specified.
Total Dissolved Solids - The total dissolved solids (TDS) concentration
of Delta waters shall be maintained below the indicated limits for the
waters specified. If a reliable correlation can be demonstrated
between TDS and EC, such correlation can be used to aid in monitoring
for compliance with these objectives.
(1)	At Cache Slough at the City of Vallejo intake, the TDS shall not
exceed 250 mg/1.
(2)	At Rock Slough at Contra Costa Canal intake, the mean tidal cycle
value TDS shall not exceed 750 mg/1 and in addition shall not
exceed 380 mg/1 for at least 65 percent of any year.
(3)	In the San Joaquin River near Vernal is, the mean average TDS
concentration shall not exceed 500 mg/1 over any consecutive
30-day period.
(4)	In eastern Delta channels, the mean monthly TDS concentration
shall not exceed 700 mg/1.
(5)	At Terminous in Little Potato Slough, at Rio Vista in the
Sacramento River, at San Andreas Landing in the San Joaquin River,
at Clifton Court Ferry in Old River, and after the initial
operation of the Peripheral Canal, at the bifurcation of Middle
River and Old River,
a.	a mean daily TDS concentration of 700 mg/1 or less when
measured on the basis of the average mean daily value for any
14 consecutive days,
b.	a mean monthly TDS concentration of 500 mg/1 or less when
measured on the basis of the average mean daily value for any
calendar month,
c.	a mean annual TDS concentration of 450 mg/1 or less when
measured on the basis of the average mean daily value for any
calendar year.
(6)	After 1 April in a dry or critical year and after 1 August in a
below normal year and until 31 December of the same calendar year,
the TDS criteria specified in (5) above may reach, but not exceed
800 mg/1 for item a, 600 mg/1 for item b, and 500 mg/1 for item c;
provided, however, the average of the values of the total
dissolved solids concentration at all of the named locations shall
not exceed, for the balance of the calendar year, the mean values
specified in (5) above.
6

-------
(7)	Whenever the recorded TDS concentration in the Sacramento River at
Green's Landing exceeds a mean 14-day or mean monthly value of 150
mg/1, the quality criteria in (5) and (6) may be changed by adding
to those values the product of 1 1/2 times the amount by which the
recorded TDS concentration at Green's Landing exceeds 150 mg/1.
(8)	At Antioch, in the San Joaquin River, the average of mean daily TDS
for any 14 consecutive days shall not exceed 450 mg/1 throughout a
period of at least 150 days in each normal or below normal water
year; provided, however, that the period is reduced to 120 days
during dry water years and 100 days during critical water years.
These objectives shall not apply when the State Board determines
that adequate substitute supplies are available to all existing
municipal and industrial water users located in the vicinity of
Antioch and Pittsburg.

shall meet the following standards at any point at
which water is withdrawn for treatment and distribu-
tion as a potable supply or for food processing
except that such standards, including the General

2)	150 mg/1 of dissolved solids attributable to
human activities.

In that portion of the Cuyahoga River from the

-------
Okl ahoma
Cleveland Southerly Sewage Treatment Plant to the
mouth of the Cuyahoga River, the dissolved solids
standards set forth in A and B shall not apply.
For chlorides, sulfates and total dissolved solids,
the arithmetic mean of the concentration of the
samples taken for a year at a particular sampling
station shall not exceed the historical "yearly mean
standard" generated at that station. Furthermore,
not more than one (1) in twenty (20) samples randomly
collected shall exceed the historical value of the
"sample standard" generated at that station.
Increased mineralization from other elements such as
calcium, magnesium, sodium and their associated
anions, etc., shall be maintained at or below a level
that will not restrict any beneficial use.
Historical data are available only for sparsely
distributed sampling stations. Therefore, care and
best judgment must be exercised in the interpolation
for intermediate locations. Further, it is
anticipated that as nonpoint sources are identified
and adequately addressed, the natural mineral
concentrations should decrease over a period of
time.
