Water samples should typically be incubated for 5 days at 20-22°C (68-72°F) when measuring biochemical oxygen demand (BOD), which is a standard practice for assessing organic matter levels. For coliform testing, samples are usually incubated for 24 hours at 35°C (95°F). The specific incubation time may vary depending on the type of analysis being performed, so it's important to follow the guidelines relevant to the test in question.
