INTRODUCTION
This report makes available to the public data on the chemical quality of the surface waters of Texas in the water year 1956. Results are presented for chemical analyses of water samples obtained daily from selected points throughout the State and also the results for a number of miscellaneous samples obtained at various points during the period October I, 1955, to September 30, 1956.
All natural waters contain dissolved mineral matter. Water in contact with rocks and soils, even for only short periods of time, will dissolve some of the mineral and organic substances. The chemical character of stream waters is dependent on several factors, such as type of soil and rock with which the water is in contact, length of time of the contact, and climatic conditions. In Texas, the chemical composition of waters varies widely from stream to stream and. often, from point to point on a particular stream.
The records of chemical analysis of surface waters given in this volume serve as a basis for determining the suitability of the waters for industrial, agricultural, and domestic uses insofar as such use is affected by the dis , solved mineral matter in the waters.
COOPERATION
This is the twelfth in a series of reports covering surface waters of Texas prepared by the U. S. Geological Survey in cooperation with the Texas Board of Water Engineers. These reports may be obtained by writing the Board of Water Engineers, Austin, Texas.
Cooperating in the collection of these data were the cities of Fort Worth and Wichita Falls, the Colorado River Municipal Water District, the Canadian River Municipal Water Authority, the Hubbard Creek Water Committee, the Lower Colorado River Authority, the Lower Neches River Authority, the Brazos River Authority, the Sabine River Authority, the Red Bluff Water Power Control District, the Chambers-Liberty Counties Navigation District, the Greenbelt Municipal and Industrial Water Association, and the U. S. Corps of Engineers.
Records for 8 stations in the Rio Grande Basin have been furnished by the U. S. Department of Agriculture. in cooperation with the International Boundary and Water Commission. COLLECTION AND ANALYSIS O~ S&~LES
The samples for which data are given were collected from October I, 1955, to September 3D, 1956. Descriptive statements are givec for each s~ling station for which a regular series of chemical analys~s have been made. These statements give the location of the stream sampling s~ation. drainage area of the stream above the station. length of time for which records are available. extremes of dissolved solids, hardness and water temperature. and other pertinent data. Records of discharge of the streams~~. or near. t~e sampling point for the sampling period are included in most tables of analyses.
Texas Board of Water Engineers-D. S. ~ealogical Survey Sampling Program
During the period October I, 1955, to Septe~ber 30. 1956, samples were collected daily at 30 points on Texas streares and twice ~eekly at ~ sampling points in Trinity Bay near the mouth of the Trinity River. In addition to the data on chemical quality included in this report, temperature data for streams at 24 of the 30 sampling stations and sedimer.t da~a for I of the sampling sta tions are available in the files of the U. S. Geological Survey. Austin. Texas. Records of chemical quality of streams at 52 additlonal sBffipling points for varying lengths of time have been published in previous reports of this series. The locations of the active and inactive sta~ions are shown on the accompanying map, and the periods of operation of all the stations are shown on the bar graph • • Water samples were usually obtained daily at or ~ear a Geclogical Survey gaging station. Specific conductance was determined on all samples. Composite samples were usually made for 10-day periods using eq~al volumes of s~ccessive samples having similar conductances. For some streams that ar~ subject to sudden and large changes in chemical composition or co,centration, saW-ples were com posited for shorter periods on the basis of the concentration of dissolved solids indicated by the measurements of specific conductance of the daily samples. At several sampling stations where changee in chemical composi:ion cccur gradually, daily samples for an entire month were composited.
International Boundary & Water Commission-U. S. Department of Agriculture Sampling Program
This report includes chemical quality records for 8 stations in the Rio Grande Basin where samples were collected by the International Boundary and Water Commission and analyses made by the U. S. Department of Agriculture, Agricultural Research Service, U. S. Salinity Laboratory, Rivecside, California. At 2 of t~e stations, samples w~re collected daily; at the other~, from 2 to 14 samples were collected each month. A single ~nthly composite sample was made up for analysis by taking from each indIvidual sample an awount of water propor tional to the volume of river flow represented by th~ sample. Results of these analyses in equivalents per million are also published in Water Bulletin Number 26 of the International Boundary and Water Commission. :ogether with streamflow and related data.
2 EXPRESSIO~ OF RESULTS
All data in the tables of analyses are reported in parts per million except those for mean discharge, tons per acre foot, tons per day, percent sodium, specific conductance, sodium-adsorption-ratio, and pH.
A part per million is a unit weight of a constituent in a million unit weights of water.
Mean discharge is reported in cubic feet per second, which is the rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and whose average velocity is 1 foot per aecond.
Dissolved solids are reported in tons per day, tons per acre-foot, and parts per million. Values reported for dissolved solids less than 1,000 parts per million are residues on evaporation and for more than 1,000 parts per million are sums of determined constituents unless noted otherwise. In obtaining the sum, the bicarbonate is calculated to carbonate by dividing by 2.03.
For those analyses in which a calculated value as sodium is shown for sodium and potassium, this value, in equivalents per million, was used in com puting the percent sodium. For those analyses in which a determined value for sodium is reported separately, this value is used in computing the percent sodium.
Sodium-adsorption-ratio (BAR) is the relative proportion of sodium to other cations in water and is defined by the equation:
SAR ca++ + Mg++ 2 where the concentrations of the constituents are expressed in equivalents per million. Waters are divided into four classes with respect to sodium hazard, the dividing points being at SAR values of 10, 18, and 26. They range from low-sodium water that can be used for irrigation on almost all soils to very high-sodium water which is generally unsatisfactory for irrigation.
Specific conductance, a measure of a water1s ability to conduct an elec tric current, is reported in micromhos per centimeter at 25°C.
A water having a pH of 7.0 is considered to be neutral; less than 7.0, increasingly acidic; and greater than 7.0, increasingly alkaline.
Sodium and potassium are reported as sodium unless listed separately in the tables.
Hardness due to calcium and magnesium and noncarbonate hardness are reported as calcium carbonate (CaC03 ).
3 The weighted averages of analyses are reported for those sampling stations for which discharge records are available. The weighted average of analyses represents the approximate composition of water that would be found in a reser. voir containing all the water passing a given station during the year, after thorough mixing in the reservoir.
The methods of analysis were the same as or modifications of those in standard publications for water analysis. 11
