A dependent clause is a group of words with a subject and a verb that does not express a complete thought and cannot stand alone as a sentence. "Although outbreaks caused by inadequate water purification have occurred" is a dependent clause because it begins with the subordinating conjunction "although" and cannot stand alone as a complete sentence.
