ppm ≈ mg/L; ppb ≈ µg/L; ppt ≈ ng/L in drinking water. Hardness in gpg = mg/L as CaCO₃ ÷ 17.1. ND means not detected at the method’s reporting limit—not zero.

MCL is a maximum contaminant level. MRDL is a disinfectant limit. Lead/copper action levels use system sampling percentiles and are not a safe-tap threshold. TTHM/HAA5 compliance uses locational annual averages.

PFOA/PFOS comparisons use EPA’s 4 ppt values. Historical detections are not a present compliance finding; EPA assesses compliance using running annual averages. Rule implementation is being reviewed. EPA PFAS benchmarks and implementation ↗

More about your local water

What this means for your home

Laredo’s 2025 report includes separate disinfection-byproduct averages for each sampling location.

The highest listed TTHM annual average is 75 µg/L at 3065 St Gerard Lane, and the highest HAA5 annual average is 56 µg/L at 3501 Socrates Lane. The residual table labels its result chlorine; the utility’s published nitrification plan also documents monochloramine operation and temporary free-chlorine conversions.

A useful local question

Should a Laredo filter be selected for chlorine or chloramine?

Choose equipment with performance appropriate to the disinfectant the utility is currently using. Laredo’s plan documents monochloramine and temporary free-chlorine conversions, so confirm the operating mode before final selection. A softener serves a separate role in mineral-scale control.

Sources and methodology

We keep each utility’s results separate, show the reported sample year, and distinguish averages, maxima and tap-sampling percentiles. Hardness classifications use USGS ranges. Missing data stays unknown.
