Where lead is found in District of Columbia

1 city where lead was detected

Cities where detected · above the action level first

Values are from the published EPA record; a contaminant that was never tested is shown as pending, never as a pass. Above the action level is a regulatory trigger for the system, not a measurement of any single home.

Treatment, if a finding establishes a need

What can carry a lead reduction claim

  • Reverse osmosis

    Semi-permeable membrane separation removing dissolved minerals, heavy metals, and persistent fluorinated chemicals down to 0.0001 microns.

  • NSF/ANSI 53NSF/ANSI 53 lead-certified filters
  • Replacing lead service lines
What does not help

Boiling does not remove a dissolved chemical compound and can concentrate it. Many pitcher and refrigerator filters carry no verified claim for a compound like this at all.
