Coliform bacteria and other potential indicator organisms in a pond.

Waters containing enteropathogenic microorganisms (i.e., Salmonella, Shigella) are considered unsafe for human consumption. Traditionally, indicator bacteria have been utilized for the assess- ment of bacteriologically unsafe waters. However, a demand for increased water quality assurance has created renewed interest in the natural relationships of enteric pathogens and indicator bacteria (14, 31, 32). The reliability of the coliform test, the utilization of Pseudomonas aeruginosa as an indicator organism, and the relationship of fecal streptococci to pollution have currently been under consideration. Furthermore, the criteria for determining these particular bacterial populations and the environmental factors capable of influencing them are becoming of utmost importance in water sanitation.
