There is a filter you can buy. I am not sure if it filters meds out. I will find out.
Bottled water you have to becareful of where it comes from. Sometimes as stated it comes right from the tap. Sometimes from a not so good area.
I think you can search your water supply threw goodle. At least i always have.
Plus in some areas letters are sent out when there is a issue with thier system.
"filtering it"
All water can be sent out and tested. Weather you are on a well or city water.
I will get the name of the filter.
