What term describes something that causes impurity?

In water quality terms, impurity refers to any substance present in water that shouldn’t be there or is present at unwanted levels. The best word for that is contaminant. It’s the broad category that covers chemical, biological, and physical substances that make water unfit for use or dangerous. Antibiotic is a specific drug and isn’t used to label impurities in general. A disinfectant is something used to remove or kill contaminants, not a descriptor of impurity itself. A pesticide is a type of contaminant, yes, but the question asks for the general term describing something that causes impurity, which is contaminant.
