Today's question: Is water with chlorine in it safe to drink?
"Plain Talk" answer: Yes. Chlorine is added during the water treatment process to kill microbial contaminants and a residual amount is left in to keep the water safe in the distribution system. USEPA limits the amount of chlorine remaining in the water at the tap to safe drinking levels, and many tests have shown that this amount is safe to drink, although some people object to the taste or smell. If this is a problem for you, chill a pitcher of tap water in the refrigerator, or let the water stand in the glass for a short while before drinking, and the taste and smell should dissipate.
