Water in Maricopa is testing 80ppm+ for nitrate is this water safe to drink or even bath in? Does RO make the water safe?

This is significantly higher than safe levels (10ppm) and has been a problem that has been addressed with the water company by authorities in the past but appears nothing is being done. It is NOT something the water Company or city are notifying residents of and this level can kill people

I would recommend researching safe water levels. You could also call your water company to get more information .
