About this area's water
Did you know
- Louisville was nearly named Lewisville - the spelling only changed in 1837 because Ohio already had one, when the post office opened.
- It calls itself 'The Constitution Town', a title city council formally adopted on April 15, 1957 after resident Olga T. Weber's campaign led to national Constitution Day and Constitution Week.
- All of the city's drinking water comes from five wells in two well fields; the plant averaged 828,000 gallons a day in 2025, about 41% of its 2.0 MGD rating, and pressure is held by three elevated tanks totalling 1.6…
- UCMR 5 testing found none of the six PFAS compounds regulated by the 2024 federal rule in Louisville's finished water - only a trace of the unregulated short-chain PFPeA at 0.003 ug/L.
- In the late 1800s the town supported roughly twenty saloons alongside plow manufacturers, breweries, tanneries and mills, giving it what local history calls a rather notorious reputation.

What the records show about Louisville City
Who runs it
EPA's record describes Louisville City as owned by a local government. It has 3,100 service connections and serves 9,186 people.
EPA classes it as a community water system, one that serves the same residents all year.
Its office telephone on EPA's record is 330-875-5644.

How the water is treated
EPA's treatment table registers these steps for Louisville City: aeration, chlorine disinfection, iron and manganese removal, and fluoridation.
The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.
Source: EPA Safe Drinking Water Information System (SDWIS) treatment table (EPA Envirofacts, pulled September 2026).
Violations
EPA's record shows no health-based violations for Louisville City since 2015.
EPA logs 2 violations of any kind since 2020: 2 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records).

Lead and copper at the tap
In the sampling period ending December 2023, the 90th-percentile lead result at Louisville City was 1.2 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 2 ppb, in the period ending December 2020.
EPA has 3 sampling periods on file for Louisville City since 2016, the first ending in 2017; no period was above 10 ppb.
Every water system has to inventory its service lines, the pipes from the main to each building. In the inventory Louisville City sent EPA, 3,510 lines are counted.
H2Ohio paid the Rural Community Assistance Partnership to help this small system build its lead service line inventory (Ohio EPA).
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 46 |
| Not lead | 3,464 |
| All lines | 3,510 |
Systems sample taps in the homes most likely to have lead pipes or solder. The 90th-percentile result is the level nine in ten of the sampled homes were at or below. Lead comes mostly from service lines and house plumbing, not the source water, so a low result for the system does not clear an old house.
EPA's dashboard status for this inventory: reported all required service line types.

PFAS
EPA's fifth national round of testing (UCMR 5) took 2 samples of the water entering the pipes of Louisville City in 2024 and measured 29 PFAS.
PFOA and PFOS were not detected, against a federal limit of 4 ng/L each.
The highest PFAS result was PFPeA 3 ng/L.
Ohio EPA's own statewide sampling tested 1 plant of Louisville City (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
| Compound | Highest result | Federal limit |
|---|---|---|
| PFOA | not detected | 4 ng/L |
| PFOS | not detected | 4 ng/L |
PFAS are the 'forever chemicals' from firefighting foam, plating shops and non-stick coatings. Results are for water leaving the plant, not your tap.

Disinfection byproducts
Chlorine that disinfects water also reacts with organic matter to form byproducts. Two groups have federal limits: total trihalomethanes (TTHM, 80 µg/L) and five haloacetic acids (HAA5, 60 µg/L), judged on running yearly averages at each sampling site.
For TTHM, the average of Louisville City's samples in 2019, the last year it was sampled, was 23.8 µg/L. The worst yearly average was 45 µg/L and the highest single sample was 117 µg/L, from 27 samples taken from 2013 to 2019.
For HAA5, the average in the last year sampled was 8.6 µg/L. The worst yearly average was 12.1 µg/L and the highest single sample was 34.4 µg/L, from 27 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 23.8 µg/L (2019) | 45 µg/L | 117 µg/L | 27 |
| HAA5 | 60 µg/L | 8.6 µg/L | 12.1 µg/L | 34.4 µg/L | 27 |
A yearly average of 0 means nothing was detected in that year's samples. EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results.
Source: EPA Six-Year Review 4 compliance monitoring data, 2012 to 2019, distribution-system samples (non-detects counted as zero).
Nitrate, arsenic and radioactivity
Nitrate was not detected in 8 samples through 2019 (limit 10 mg/L as nitrogen; above 10 is unsafe for infants).
Arsenic was not detected in 3 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | not detected | 10 mg/L | 0 |
| Arsenic | 3 | not detected | 10 µg/L | 0 |
Measured in finished water: at the plant's entry points and in the distribution system; raw well and intake samples are left out. Non-detects count as zero.

Solvents and fuels
EPA's file holds results for all six solvent and fuel compounds it checked. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 4 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 4 | 0 of 4 | not detected | 0 |
"Not detected" means the lab's result was below what its method can measure, not that the compound is absent. Non-detects count as zero in the highest-result column.
Source: EPA Six-Year Review 4 compliance monitoring data, 2012 to 2019, finished water.
Farm chemicals and metals
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: chromium in 1 of 3 samples, highest 1 µg/L (limit 100); barium in 3 of 3 samples, highest 138 µg/L (limit 2,000); selenium in 1 of 3 samples, highest 1.52 µg/L (limit 50). Not detected: atrazine, alachlor, cadmium, mercury, and thallium, in 3 samples each.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 3 | 0 of 3 | not detected | 0 |
| Alachlor | Farm chemical | 2 µg/L | 3 | 0 of 3 | not detected | 0 |
| Chromium | Metal | 100 µg/L | 3 | 1 of 3 | 1 µg/L | 0 |
| Cadmium | Metal | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Barium | Metal | 2,000 µg/L | 3 | 3 of 3 | 138 µg/L | 0 |
| Mercury | Metal | 2 µg/L | 3 | 0 of 3 | not detected | 0 |
| Selenium | Metal | 50 µg/L | 3 | 1 of 3 | 1.52 µg/L | 0 |
| Thallium | Metal | 2 µg/L | 3 | 0 of 3 | not detected | 0 |
Non-detects count as zero in the highest-result column.

Bacteria in the pipes
From 2012 to 2019, 0 of 962 routine total coliform samples taken in the distribution system at Louisville City tested positive (0%); in 2019, the last year on file, 0 of 120 did.
A positive coliform test is a warning sign, not a violation by itself. E. coli is a sign that human or animal waste may have reached the water. Coliform counts are routine samples only; E. coli counts include repeat samples.

Fluoride
The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Louisville City adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at Louisville City.
Measured fluoride: 0.75 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.66 to 0.75 mg/L across 3 samples in 2012 to 2019.
The recommended level for preventing tooth decay is 0.7 mg/L; the federal limit is 4 mg/L. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Lithium
Lithium was found in 2 of 2 UCMR 5 samples at Louisville City, highest 9 µg/L; detections averaged 9, last sampled in 2024.
Lithium is not regulated. EPA's draft health reference level is 10 µg/L, and it occurs naturally in deep groundwater, so well systems in the northwest run highest.
Source: EPA UCMR 5 occurrence data (final release, August 2026), samples from 2023 to 2025.
Water and sewer bills
Ohio EPA's 2023 rate survey puts the water bill at Louisville City for a household using 5,000 gallons a month at $445 a year, about $37 a month.
The sewer bill in the same survey is $471 a year at 5,000 gallons a month.
| Use | Water, per year | Sewer, per year |
|---|---|---|
| 2,500 gallons a month | $275 | $270 |
| 5,000 gallons a month | $445 | $471 |
| 8,000 gallons a month | $609 | $666 |
The survey lists it as “Louisville”. These are inside-city rates and annual bills at the use shown.
