INTRODUCTION
The Wabash River in the Terre Haute area has been studied from time to time
with one intensive survey conducted during the summer of 1949. Predictions made
on the ability of the river to handle organic loads were made at that time. Substantial
reduction in BOD discharges were made by industries and the city of Terre Haute over
the next several years. During the 1949 Survey, the water quality was measured by
dissolved oxygen analyses on samples collected by the State and the ORSANCO
monitor located near Hutsonville, Illinois, about 37 river miles below the major outfalls from the Terre Haute area. The general impression was that there was apparently
considerable pollution being discharged in the Terre Haute area, because depressed
dissolved oxygen concentrations were noted. It is believed that it was this general
impression that prompted the "implementation program for water quality enhancement" published by the Indiana Stream Pollution Control Board.
WESTON SURVEY PROGRAM
The situation just related prompted the Weston Paper and Manufacturing Co. to
institute sampling for dissolved oxygen analysis on a twice a week schedule that has
been maintained during a two year period.   The Survey will continue in the future.
Six sampling stations were established between Clinton, Indiana and Hutsonville, Illinois.   They were:
Clinton, State Road 63 Bridge    Mile -    0
Terre Haute State Road 63 Bridge  Mile - 13
Terre Haute U. S. Highway 40 Bridge     Mile - 15.5
Terre Haute Interstate 70 Bridge  Mile - 17.5
Darwin's Ferry, Ferry     Mile - 35.5
Hutsonville, Illinois, Bridge      Mile - 54.5
The results of the surveys are shown in Tables I to XXV. The data collected by the
Ohio River Valley Sanitation Commission monitor at Hutsonville, at approximately
the same hour that the Weston samples were obtained is also found in Tables II to
XXV in the column with the Weston Hutsonville data.
