Yes, but people in developing countries with bad water supplies also die all of the time of cholera, dysentery and other water-borne diseases. I'm not an overly paranoid pregnant person, and DC water is far from the biggest of my concerns, but there have been significant problems in the past with the DC water supply and the comparison to TTC in the 3rd world doesn't help answer the OP's question.
