Summary:
- "This investigation had for its purpose the determination of first, the inefficiency of the Perryton, Texas, sewage disposal plant proper; and second the potential effectiveness of a lagoon now used to complete the sewage purification; and consequently, offset an apparent health hazard. The problem, as pursued, has consisted of first, the collection of sewage samples from the six stations listed in Table 1 over the period of time from September 23, 1949 to May 14, 1950; second, a quantitative analysis of each sample in order to determine the number of bacterial organisms present; third, a qualitative analysis of each sample in order to determine more expecially the presence of members of the genera Aerobacter, Escherischia, Salmonella and Shigella; and fourth, an attempt to evaluate the potentialities of the natural purification factors of the lagoon."--leaf 6.
