At the source
EPA UCMR 5 sampled this utility for 29 PFAS and lithium from April 13, 2023 to Oct. 16, 2023. None was found above EPA’s reporting levels.
In treatment
No federal results for this stop. Disinfection byproduct, chlorine and fluoride levels are in Hardinsburg Ro WTP’s own annual report, which it must send you every year.
In the pipes
Lead and copper, from the homes the utility samples. Your own service line, solder and fixtures decide yours.
- Limit and goal 1.31.7
In the latest period, 9 in 10 homes sampled were at or below 1.7 ppm, above the 1.3 ppm action level.
EPA SDWIS, lead and copper monitoring periods ending 2005. The line stops at the latest period; each tick under it is an earlier one.

The last stretch is your own plumbing. A certified lab test is the only way to know what reaches your glass. Lead in your water: what to do
Tested and not found
Below EPA’s minimum reporting level in every sample taken from April 13, 2023 to Oct. 16, 2023. Not found means not measured above that level, which is not the same as zero.

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 Hardinsburg Ro WTP’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 April 13, 2023 to Oct. 16, 2023.
