How Laredo compares2,738 cities detected lead; 1,407 more were below the reporting limit and aren’t plotted. A position here is not a verdict on the water.

What this means: Laredo’s result is below the federal action level. It is a citywide figure; plumbing in an individual home can differ.
City water is not your tap
Plumbing inside a home can add lead the record can’t show.
The city report tells you about the water system. A tap test tells you about your household.

Don’t misread thisA city-wide result does not tell you your tap result
A reported city-wide lead concentration is not a measurement of the water coming from every household tap. Lead can enter water through service lines, faucets, fixtures and plumbing materials. “Laredo reported 1.37 µg/L” does not mean your water has 1.37 µg/L.
CITY OF LAREDO's most recent lead 90th-percentile result (2022–2024) was 1.37 µg/L, below the 15 µg/L action level. It comes from sampled homes; your own pipes decide what reaches your tap.
Does Laredo have lead service lines?+
In EPA's service line inventory (2026Q2), CITY OF LAREDO reported 0 lead service lines, 0 galvanized lines requiring replacement and 37,615 of unknown material, out of 83,292 lines in total. Unknown lines have not yet been identified and may include lead.
How much lead was detected in Laredo water?+
1.37 µg/L at the 90th percentile of the homes CITY OF LAREDO sampled under the Lead and Copper Rule (2022–2024).
Is Laredo's lead level below the legal limit?+
It is below the 15 µg/L federal action level. Lead has no MCL: the action level is a treatment trigger, and EPA's health goal for lead is zero.
Can my home have more lead than the city report shows?+
Yes. Lead usually enters water from service lines, solder and fixtures between the main and your tap, so one home can measure higher than the citywide figure. Only a test of your own tap shows it.
How do I know if my home has a lead service line?+
Ask CITY OF LAREDO whether your address appears in its service line inventory, which utilities must publish. You can also look where the water pipe enters your home: lead pipe is dull grey, soft, and shows shiny metal when scratched gently.
How do I test my Laredo tap water?+
Use a state-certified lab for an exact number, or a screening kit for a quick range. For lead, take a first-draw sample: water that has sat in the pipes for at least six hours.
What filter removes lead from Laredo water?+
One whose current certification names lead for the exact model: NSF/ANSI 53 (carbon) or NSF/ANSI 58 (reverse osmosis). Until then, run the cold tap for a few minutes after water has sat for hours, and use only cold water for drinking and cooking.
What certification should I look for in a lead filter?+
NSF/ANSI 53 or 58 with lead listed for the exact model, checked in the certifier's listing (NSF, WQA or IAPMO).
Should I replace my lead service line?+
If your home has one, replacing it removes the main source of lead. Ask CITY OF LAREDO first; many utilities replace these lines for free or share the cost.
