 D.C. Water's John Lyle says there's no indication that the water is contaminated. But we issue the advisory as a precaution while we test the water. So until further notice, use bottled water or boiled tap water. To a rolling boil for a minute, then let it cool, and then store the water in a clean, covered container. That's for drinking, brushing your teeth, preparing food, washing fruits and vegetables, preparing infant formula, making ice, or giving water to your pets. Neil Lloyd.
