Power Outages: What to do After a Blackout

After a Blackout: Water Treatment

Black outs can cause contaminated water because water treatment plants do not operate without electricity. Untreated water may cause diseases such as dysentery, cholera, typhoid, and hepatitis. Contaminated water does not always smell or taste bad. All water of uncertain purity should be treated before use. Listen for guidance from your local water utility about whether your drinking water is safe and steps you can take to purify it if necessary.
