 General Observations -• Western Lake Erie



      The Detroit Program Office field crew made observation runs on




 Western Lake Erie on June 30, July 13, and August 22.  On all three



 occasions, Lake Erie was free of oil and debris.  No swimmers were



 seen at Sterling State Par!:*. Bubbles were observed rising from the



 River Raisin bottom (turning basin to Lake Erie).  Patches of sewage



 (trace of oil) having a strong odor were also found along the lower




 stretch of this river.
•^Located on Lake Erie immediately north of the mouth of the River Raisin

 LABORATORY METHODS
     The analytical methods used, "by the laboratory for physical and
chemical analyses were the procedures published in "Standard Methods
for the Examination of Water and T,Tastevater/' 12th Edition, 1965«
Additional analytical procedures and modifications developed "by the
Chicago Program Office, Federal Uater Pollution Control Administration
were employed as required in the analysis of bottom sediment material.
Modifications have been nade on some of the methods to improve the
sensitivity or to expedite a systematic analytical scheme.  Before
adopting any modification a thorough study was made to evaluate the
affect of the chanjo.
     To assure continually reliable data,, reference standards of known
composition and blanl;s vera ar.clyzod. simultaneously with all tests.
     A suz^ation of the analyses performed is shown on Table 18 .
Specific techniques or modifications 'co "Standard Methods" procedure
are shown where applicable.
