Mr. Jim Raport 107 Robinson Gymnasium Kansas University Lawrence, Kansas Dear Mr. Raport: The rating of these samples is good from a bacteriological standpoint. In our swimming pool ratings, samples which show a bacterial count of not over 200 bacteria per cubic centimeter are given a rating of excellent. The good rating is used for samples showing bacterial count of over 200- Samples showing the presence of coliform organisms are given ratings of fair and un- satisfactorye Usually samples showing a residual chlorine content of .6 parts per million, as these samples did, have a bacterial count of less than 200. If you wish to have regular analyses made will you please come to the laboratory for sterilized bottles and we can make arrangements for additional analyses. Very truly yours, DIVISION OF SANITATION Carrandra Kitten . CR:R
