Why is there "ed" at the end of "infect" when "become" has a "S" on it? Very Confusing

Once water becomes infected with these bacteria, it becomes a health hazard.

Water is the grammatical subject of the first clause and therefore the 's' is needed in becomes, which is inflected in the third person singular, present tense. Infected is a past participle used adjectivally; it tells us what the water is like after it becomes infected with bacteria. Think of becomes infected as if it were a passive: is infected.
