There are several ways to test for coliforms in our drinking water systems. Today, we will talk about one of the most common test methods, Colilert.
Below is a short video that describes how Colilerts are used and how we determine if a sample is positive for coliforms and ecoli. You’ll see all the tools needed to perform and record sample data.
Different companies may sell or make this test method, but this video is just a good source of information to see a test being run instead of just reading about it. For most people, once they can see how something is done, they can repeat the process. Colilert is accurate and used greatly in our water systems. Hopefully, this will give you a good understanding of its functionality.
