Take this with a pound of salt, as the "patients" were very high-drama people with a penchant for hyperbole, but I know 3 students (2 have graduated and one is in clinics) who claim to have contracted - and confirmed - cases of Giardia when they lived at the White House in L'anse aux Epines. As far as I know, they just got the "poops" but I did not investigate it that closely myself - everybody in the house just boiled their drinking water (before putting it in the pitcher filter and ice trays) for about a month and we never heard about it again. It was probably just drama, though.
