Until tests results show the water is safe to drink, you should not drink the water without boiling it first. Although waterborne diseases are extremely rare, chances are if you are in good health, you will not get sick from drinking the water. The risk is higher for infants, some of the elderly, and people with compromised immune systems. They should not drink the water until it is deemed safe to drink. If you have specific medical concerns it is suggested that you seek advice from your health care provider.
