LISLE, Ill. The Water Quality Association warns that Hurricane Dorian, expected be a Category 3 storm before it hits the Atlantic coast Labor Day weekend, poses a threat to drinking water for people affected by the storm, but that there are precautions that can be taken to protect residents in the affected areas.

“Our concern is for anyone who may be caught in the path of Dorian or who will be returning to their homes once the storm has passed,” said WQA Executive Director Pauli Undesser. “Residents should be aware of possible drinking water contamination as a result of massive flooding.

Dorian became a Category 1 hurricane just before making landfall on the U.S. Virgin Islands Wednesday and is expected to hit the Atlantic coast as a Category 3 storm late Sunday or Monday morning. Its path appears to be taking it toward Florida, although it’s possible it could veer a little farther north.

Florida and Georgia residents in the storm’s potential path already should have an adequate drinking water supply ready, said WQA Technical Affairs Director Eric Yeggy. The general rule of thumb is to have one gallon of drinking water per day for each individual in a home, or 12 gallons to last a family of four for three days.

Once the water supply has been compromised by flooding, passing water through home water treatment equipment not intended to purify microbiologically unsafe water would not provide sufficient assurance of potability. WQA recommends residents pay attention to local boil water alerts and other warnings following severe flooding because local water supplies can be tainted with debris, bacteria and other contaminants. Water treatment equipment will also need to be sanitized after flooding.
