| Intended Use |
Detection of coliform bacteria in water treatment plants or distribution systems using the presence-absence coliform test. |
| Product Summary and Explanation |
The Presence-Absence (P-A) test serves as a presumptive detection method for coliforms in water. This streamlined procedure simplifies the traditional multiple-tube test by inoculating a single 100 mL sample into a specific culture bottle. The goal is to ascertain the qualitative presence or absence of coliforms, determined by lactose fermentation. This method is grounded in the principle that coliforms and other indicator organisms should not be detected in a 100 mL water sample. |
| Key Benefits |
With its straightforward approach, the P-A test enhances coliform detection efficiency, particularly in samples where an abundance of organisms may obscure growth and complicate identification. Studies comparing this method with the membrane filter technique highlight its reliability in maximizing coliform detection. The P-A test aligns with established standard methods for water testing, including guidelines set forth by the U.S. EPA. |
