About this area's water
Did you know
- North Baltimore does not dam its creek - it pumps from a single Rocky Ford Creek intake into two upground (offstream) reservoirs, whose embankments run about 7,200 feet and are rated a high hazard potential dam in the…
- The village's plant is a lime-softening plant with upflow clarifiers, and it runs at only about 38% of its 1.658 million gallon per day capacity.
- Not one of the twenty homes sampled in 2025 exceeded the lead or copper action level, and only one had any detectable lead at all - yet the village still began replacing lead service lines in September 2026.
- Of the six PFAS compounds now federally regulated, all were non-detect in four rounds of 2025 sampling; the only PFAS the village found at all was unregulated PFBA, at a few thousandths of a unit.
- The village turned 150 in 2026 and threw the NB 150 Festival that June.
History4
- 1876North Baltimore was incorporated as a village; the village seal reads 'ESTD 1876' and the village marked its sesquicentennial with the NB 150 Festival in June 2026.
- 1969The two North Baltimore upground reservoirs were completed - earthen embankments up to 24 feet high and about 7,200 feet long, engineered by Floyd G. Browne & Associates, per the National Inventory…
- 2025Council adopted Resolution No. 30-2025 authorizing the village administrator to apply for and enter into an Ohio EPA Water Supply Revolving Loan Account agreement for planning, design and/or…
- 2026Construction of the village's lead service line replacement project was scheduled to begin in mid-September, per the village administrator's September 2026 report to council.
Treatment & pressure
How it is treated
Surface water from a single intake on Rocky Ford Creek is pumped into two offstream upground reservoirs and then treated at the village's lime-softening plant, which uses upflow clarifiers to settle out contaminants, followed by filtration and chlorination. Plant treatment capacity is 1,658,000…

What the records show about North Baltimore Village
Who runs it
EPA's record describes North Baltimore Village as owned by a local government. It has 1,265 service connections and serves 3,432 people.
EPA classes it as a community water system, one that serves the same residents all year.
EPA's record says it has substantially implemented source water protection under Ohio's program, dating the program from 2023. Its office telephone on EPA's record is 419-257-2394.

How the water is treated
EPA's treatment table registers these steps for North Baltimore Village: aeration, corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, fluoridation, lime softening, powdered activated carbon, and sand or media filtration.
The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.

Violations
EPA's record shows no health-based violations for North Baltimore Village since 2015.
EPA logs 3 violations of any kind since 2020: 3 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 2025, the 90th-percentile lead result at North Baltimore Village was 0 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027. A result of 0 means at least nine in ten of the homes sampled had no lead detected.
The highest result on file is 1 ppb, in the period ending December 2022.
EPA has 6 sampling periods on file for North Baltimore Village since 2016, the first ending in 2016; 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 North Baltimore Village sent EPA, 1,192 lines are counted.
| Material | Lines |
|---|---|
| Lead | 84 |
| Galvanized, needing replacement | 25 |
| Unknown material | 0 |
| Not lead | 1,083 |
| All lines | 1,192 |
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 4 samples of the water entering the pipes of North Baltimore Village in 2025 and measured 29 PFAS.
PFOA and PFOS were not detected, against a federal limit of 4 ng/L each.
The highest PFAS result was PFBA 5.5 ng/L.
Ohio EPA's own statewide sampling tested 1 plant of North Baltimore Village (latest sample October 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 North Baltimore Village's samples in 2019, the last year it was sampled, was 60.5 µg/L. The worst yearly average was 60.9 µg/L and the highest single sample was 118 µg/L, from 71 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 27.4 µg/L. The worst yearly average was 27.4 µg/L and the highest single sample was 37.4 µg/L, from 71 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 60.5 µg/L (2019) | 60.9 µg/L | 118 µg/L | 71 |
| HAA5 | 60 µg/L | 27.4 µg/L | 27.4 µg/L | 37.4 µg/L | 71 |
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.

Nitrate, arsenic and radioactivity
Nitrate: the highest of 96 samples was 1.64 mg/L (as nitrogen) in 2017; in 2019, the last year sampled, the highest was 0.86 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 8 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 96 | 1.64 mg/L | 10 mg/L | 0 |
| Arsenic | 8 | 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 8 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 8 | 0 of 8 | 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.

Farm chemicals and metals
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 1 of 8 samples, highest 27.8 µg/L (limit 2,000). Not detected: atrazine in 10 samples, alachlor in 10 samples, chromium in 8 samples, cadmium in 8 samples, mercury in 8 samples, selenium in 8 samples, thallium in 8 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |

Bacteria in the pipes
From 2012 to 2019, 0 of 479 routine total coliform samples taken in the distribution system at North Baltimore Village tested positive (0%); in 2019, the last year on file, 0 of 59 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 North Baltimore Village adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at North Baltimore Village.
Measured fluoride: 0.77 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.77 to 0.99 mg/L across 8 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 not detected in 4 UCMR 5 samples at North Baltimore Village, last sampled in 2025 (the method reports from 9 µg/L).
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.
Algal toxins
Ohio EPA tests for microcystin, a toxin that harmful algal blooms can release, in raw water at the intake and in treated water.
At the intake, microcystin was detected 32 times in 257 raw-water samples, across 4 bloom seasons (2021 to 2025); the highest raw-water result was 20 µg/L on December 19, 2023. The highest raw-water result since 2024 was 2.853 µg/L.
Microcystin was never detected in treated water (131 samples).
In all, 388 samples from 2016 to 2026, the latest on August 14, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 257 | 32 | 20 µg/L |
| Treated water | 131 | 0 | not detected |
The ten-day advisory levels for treated water are 0.3 µg/L for children under six and 1.6 µg/L for everyone else. Any detection at the intake triggers more frequent testing until two clean weeks.

How well the service area is mapped
EPA estimated the service area of North Baltimore Village with a computer model rather than drawing it from the utility's map, so its edges are approximate.
Counting the people who live in the ZIP codes it overlaps, this atlas estimates 3,412 residents are inside the boundary, 99% of the 3,432 people North Baltimore Village reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
