Nitrate
Santa Croce water has a low nitrate content :  only 1.2 mg/l
Low nitrate content denotes pure water. There are no existing minimum daily limits but:
- The World Health Organization recommends mineral waters with a limit of nitrate less than to 10 mg/l for expectant mothers and infants.
- A CEE directive recommends  a maximum admissible quantity of 45 mg/l
The amount of nitrate equaling 1.0 mg/l make Santa Croce especially recommended for women during pregnancy and infants. Less Nitrate, more purity
