5.0ppb

90th percentile, 2023 to 2025

The 90th-percentile result was 5.0 ppb, below the 15 ppb action level. EPA’s health goal for lead is zero.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 2004 to 2025. The pointer marks the latest period; each blue tick is an earlier one.

Also found, with no federal limit

EPA measured these PFAS to learn how often they occur. None has a legal limit or a health goal yet.

Tested and not found

Below EPA’s minimum reporting level in every sample taken from May 15, 2024 to Nov. 14, 2024. Not found means not measured above that level, which is not the same as zero.

Violations since 2016

No health-based violations on file with EPA since 2016.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report cannot tell you

  • Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in Little Falls’s own annual report, which it must send you every year.
  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
  • Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from May 15, 2024 to Nov. 14, 2024.
