The News & Observer editorial "Looking out for lead" (July 9) conveyed a misconception that we wish to correct. The U.S. Environmental Protection Agency does not have stated guidelines concerning the removal of faucet aerators before testing for lead in drinking water. We were unaware that water-treatment facilities may be making such a recommendation. Since this matter came to our attention, we have begun looking into it to determine whether we need to provide supplemental guidance on the issue. We hope to make that determination soon.
