Lead in tap water: EPA's sample results by water system
Water systems test taps for lead; EPA records the 90th-percentile result of each sampling period. Here are the systems whose newest result is above EPA's action level of 15 ppb. Enter your ZIP code to find your system.
Lead: where the newest test is above EPA's action level (15 ppb)
425 of 47,626 systems with a lead result on file are above 15 ppb in their newest sampling period (results since Oct. 13, 2021), serving 1,153,517 people; 655 more have an older result over the level and nothing newer on EPA's file. Exceedances of these action levels are not violations, but trigger other requirements to limit exposure to lead and copper in drinking water. The action level is not a health standard. Values as EPA reports them.
