We have well and softner and never had problems with our peeps.Both us and all our animals drink it and never had a problem.We do have it tested now in then but my husband is the lab tech for the water treatment plant for the city so it's free
I would think city water would be more harmful to them with all the chlorine they put in it.My husband sees the process and refuses to drink city water now.LOL
Your peeps should be just fine.If you must I would boil it to take the nitrates out of it if your that concerened.
