Middleport Village treats its own water from Groundwater wells (3 wells).
The system's record
The Ohio Department of Health's fluoridation report (CDC My Water's Fluoride) lists Middleport Village as buying its water from Pomeroy Village; EPA's inventory shows its own sources as primary with Pomeroy Village as an emergency connection. The two records may reflect a blend or a recent switch.

About this area's water
Did you know
- The name Middleport refers to the town's spot on the Ohio River roughly halfway between Pittsburgh and Cincinnati; the site went by Sheffield, Coalport and Salisbury before that.
- The village keeps a standing back-up water connection to neighboring Pomeroy - and reported in its 2024 CCR that it never had to open it that year.
- Middleport's 2024 gross alpha result, 15.8 pCi/L, came in numerically above the 15 pCi/L MCL, yet the CCR's Violations column for that row reads 'No.'
- The village still runs combined sewers, so heavy rain sends untreated stormwater and sewage into the Ohio River - the problem a 2025 Appalachian Regional Commission grant on Third Street is meant to chip away at.
- Middleport publishes essentially nothing about what water costs: no rate ordinance, no schedule, just a link to a third-party payment portal.

History5
- 1798Village history dates the original Leading Creek Settlement to 1798, settled by New Englanders and Revolutionary War veterans arriving by flatboat from Marietta, followed by German immigrants.
- 1820sThe village itself was laid out during the 1820s. It carried three earlier names - Sheffield, Coalport and Salisbury - and absorbed nearby settlements including Vinton and Tarker's Landing.
- 1920Population peaks at 3,772, then declines through the century to 2,530 in 2010 and 2,208 in 2020.
- 2024Village operated its three-well groundwater system (Wells #4, #7, #8, all in use) with no violations in any category of the CCR table and a current unconditional License to Operate.
- 2025Environmental assessment for the ARC-funded Third Street Sanitary Sewer Improvements signed Aug. 12, 2025 with a Finding of No Significant Impact; combined FONSI / notice of intent to request release…

Supply stress
Ohio EPA's source water assessment rates the Middleport well field HIGH SUSCEPTIBILITY to contamination - it is a shallow alluvial aquifer in the Ohio River valley. Quantity is not the constraint: average daily use in 2024 was 140,800 gallons across three wells, and the Pomeroy interconnection was not needed at all during the year. The…

Sewers
Sanitary
Village-operated sanitary collection. The 2025 federal environmental assessment for the ARC-funded Third Street project states plainly that 'Middleport has combined sewer and storm collections systems, which causes the combined sewers to often exceed their capacity, especially during heavy rain events. This results in discharges of…
Storm
Not separate. Per the same 2025 environmental assessment, storm collection is combined with the sanitary system, and the combined sewers overflow to the Ohio River in heavy rain. No standalone stormwater utility or fee is published.

How the water is treated
EPA's treatment table registers these steps for Middleport Village: chlorine disinfection.
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 counts 1 health-based violation for Middleport Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. It falls into 1 separate problem (one contaminant or rule in one year); the table lists it.
EPA logs 7 violations of any kind since 2020: 2 for required testing that was missed or reported late; 4 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 1 health-based.
| Year | Contaminant or rule | Kind | Measured | Limit | Status in EPA's record |

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Middleport Village was 1.1 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 1.6 ppb, in the period ending December 2023.
EPA has 5 sampling periods on file for Middleport Village 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 Middleport Village sent EPA, 867 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 3 |
| Unknown material | 826 |
| Not lead | 38 |
| All lines | 867 |
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
Ohio EPA's own statewide sampling tested 2 plants of Middleport Village (latest sample March 2021). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
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 Middleport Village's samples in 2019, the last year it was sampled, was 6.3 µg/L. The worst yearly average was 14.4 µg/L and the highest single sample was 17.2 µg/L, from 15 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 0 µg/L. The worst yearly average was 9.3 µg/L and the highest single sample was 18.7 µg/L, from 15 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 6.3 µg/L (2019) | 14.4 µg/L | 17.2 µg/L | 15 |
| HAA5 | 60 µg/L | 0 µg/L | 9.3 µg/L | 18.7 µg/L | 15 |
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: the highest of 67 samples was 8.8 mg/L (as nitrogen) in 2014; in 2019, the last year sampled, the highest was 1.07 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 7 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 67 | 8.8 mg/L | 10 mg/L | 0 |
| Arsenic | 7 | not detected | 10 µg/L | 0 |
| Combined radium | 1 | not detected | 5 pCi/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 18 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 18 | 0 of 18 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 18 | 0 of 18 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 18 | 0 of 18 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 18 | 0 of 18 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 18 | 0 of 18 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 18 | 0 of 18 | 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 all nine herbicides and metals it checked. Detected: barium in 7 of 7 samples, highest 83.1 µg/L (limit 2,000). Not detected: atrazine in 5 samples, alachlor in 5 samples, 2,4-D in 3 samples, chromium in 7 samples, cadmium in 7 samples, mercury in 7 samples, selenium in 7 samples, thallium in 7 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |

Bacteria in the pipes
From 2012 to 2019, 1 of 384 routine total coliform samples taken in the distribution system at Middleport Village tested positive (0.26%); in 2019, the last year on file, 1 of 48 did. E. coli was never found in the 1 sample tested for it.
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 Middleport Village buys its water from Pomeroy Village, a system that has fluoride from natural sources, but at a level below what is recommended for preventing tooth decay, and does not adjust it. The level it reports is 0.16 mg/L.
EPA's treatment table lists no fluoridation step at Middleport Village.
Measured fluoride: none was detected in 7 samples at the plant's entry points 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.

How well the service area is mapped
EPA estimated the service area of Middleport 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 2,288 residents are inside the boundary, 94% of the 2,446 people Middleport Village reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
