The ZIP code it serves
The short answer
1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Nitrate, above the legal limit. 3 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2024.
Nitrate, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride and chromium (total): Kansas’s own results, samples taken from Feb. 4, 2020 to Jan. 21, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Nitrate
Comes from the source
12ppm
Highest sample; found in 17 of 17
2026, one sample: 7.1 ppm
From 2020 to 2023, two samples were above EPA’s legal limit of 10 ppm, the highest 12 ppm in 2020. One came back under the limit on the next sample at the same point and one has no follow-up sample on file within 30 days. In 2026, the latest year on file, its one sample was 7.1 ppm. EPA recorded a violation for nitrate at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 12 ppm, in 2012, and EPA recorded violations in 2012 and 2019.

Above the health goal2
Lead
Comes from pipes, often your own
2.9ppb
90th percentile, 2022 to 2024
In the latest period, 9 in 10 homes sampled were at or below 2.9 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Arsenic
Comes from the source
1.3ppb
Highest yearly average, 2021 to 2024
2024: not found
Averaged by year, the highest was 1.3 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.8 ppb, in 2012.

Forms or is added in treatment
63ppb
Highest yearly average, 2020 to 2023
Averaged by year, the highest was 63 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 19 ppb, in 2013.

2024, one sample: 1.2 ppb
Averaged by year, the highest was 1.3 ppb, in 2021, below EPA’s legal limit of 100 ppb. In 2024, the latest year on file, its one sample was 1.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.6 ppb, in 2012.

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.”
- NSF/ANSI 53
Claims: Nitrate/Nitrite (30 ppm challenge), Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: Nitrate, Lead, Arsenic
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Nitrate/Nitrite Reduction, Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: Nitrate, Lead, Arsenic
Other certifiers’ wording: Nitrate; Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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.

Hardness
Very hard, 535 mg/L (31.3 grains per gallon), at its one sampling point, 2015 to 2024.
Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

What this report can’t tell you
Everything else. Nitrate, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride and chromium (total) results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Lucas’s own annual report, which it must send you every year, has the contaminants this page does not show.
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.
What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.
Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Kansas’s results run from Feb. 4, 2020 to Jan. 21, 2026.
