In brief: Yes

The infective form (cyst) of the parasite is expelled in the waste of the carrier human or animal & makes it into water. It is microscopic and often present in wadeing pools, ponds, on diaper changing tables, etc.
A contaminated hand or drink may then carry it into the mouth where it begin its life cycle again, traveling to the intestines to live & reproduce.
