Quick Facts: Lead
How do I know if my water is contaminated? Since you can't see, taste or smell lead, testing is necessary. D.C. residents may be eligible for free testing; call WASA's hotline, 202-787-2732, to find out.
What are the health risks? Elevated levels of lead in the bloodstream can damage the brain, nervous system, red blood cells and kidneys. Health officials have advised pregnant women and chilren under 6 in homes with lead services to stop drinking unfiltered tap water immediately and to get blood tests. The D.C. Department of Health can provide more information on blood testing; 202-535-2690 or 202-535-2626.
How does lead get into the water? Most contamination is from corrosion of lead pipes in the home or in lead service lines that connect to public water lines.
Do household water filters remove lead? Some water pitchers and faucet filtration systems are certified to reduce lead; others remove things like chlorine, but not lead. Read product packaging to check its certification.
