Two things are certain here diarrhoea and water slides are two things that should never be in close proximity.
According to The Wrap, NBC has halted production of the summer show over the discovery of giardia nearby in the area of production. Giardia is a parasite like infection that you guessed it causes obscene problems in the bathroom.
It is unclear if the show will actually be delayed because of the discovery, but, giardia is no joke. If one eats; consumes, or even drinks water contaminated with the tiny parasite --- may the force be on their side.
