Should I buy bottled water?

The Portland Water District water is of excellent quality and it meets all federal drinking water standards. However, those immuno-compromised, such as people with cancer undergoing chemotherapy, people undergoing organ transplants, people with AIDS/HIV or other immune system disorders, or some elderly and infants, should consult a doctor. All drinking water, including bottled water, may reasonably be expected to contain small amounts of contaminants.
