Publication Abstract

Quality of Surface Water in Illinois, 1966-1971 Harmeson, Robert H., Thurston E. Larson, Laurel M. Henley, Robert A. Sinclair, and James C. Neill, 1973  Illinois State Water Survey, Champaign, IL,  ISWS B-56    Full Text Available

This publication summarizes data on surface water quality in 25 streams at 30 sampling locations during the 5-year sampling period from 1966 through 1971. Selected data from Water Survey Bulletins 45 and 54 are included in order to make comparisons of water quality during different time periods.

Results of statistical analyses, with graphic summaries, for temperature, turbidity, total dissolved minerals, hardness, alkalinity, nitrate, and manganese are given. Available data on phosphates are included in the statistical analyses. Summaries of these data for each sampling location, arranged alphabetically by stream name, are accompanied by the tabulations of mineral quality for the streams sampled, with available physical data.

The analyses of water quality by statistical means present a representative picture of stream conditions during a particular sampling period. These data can serve as a base for comparison and evaluation of existing quality with man-made standards that are often established arbitrarily or may be based on more or less ideal conditions.
