Also means
polluted
Usage Note
Contaminado describes anything that has been made impure by an external agent — water, soil, air, or even a sample in a lab. The feminine form is contaminada. It is the past participle of contaminar, so it also appears in compound tenses: el río ha quedado contaminado. Learners should not confuse it with infectado, which implies a biological pathogen specifically.
Examples
"El agua del río está contaminada."
Natural Translation
The river water is contaminated.
