COD Test!

This is a test that measures the Chemical Oxygen Demand (COD) in water! COD is a measure of how much oxygen needs to be consumed in order to chemically react with the organic matter in a solution. In other words, COD measures how much organic matter is in a solution by asking "how much oxidation would need to happen to eliminate all these organic compounds?".

It also happens to be a very colorful test.
