How the water is treated

EPA's treatment table registers these steps for Steubenville, City Of: corrosion control, coagulation and settling, chlorine disinfection, fluoridation, 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 counts 4 health-based violations for Steubenville, City Of since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. They fall into 4 separate problems (one contaminant or rule in one year); the table lists them all.

EPA logs 3 violations of any kind since 2020: 3 health-based.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Steubenville, City Of was 2.1 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.

The highest result on file is 2.2 ppb, in the period ending December 2022.

EPA has 5 sampling periods on file for Steubenville, City Of 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 Steubenville, City Of sent EPA, 10,610 lines are counted.

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 Steubenville, City Of in 2023 and measured 29 PFAS. No PFAS was detected, PFOA and PFOS (federal limit 4 ng/L each) among them.

Ohio EPA's own statewide sampling tested 1 plant of Steubenville, City Of (latest sample June 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.

Ohio EPA's current sampling status map lists 1 plant of Steubenville, City Of as sampled, most recently October 2023.

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 Steubenville, City Of's samples in 2019, the last year it was sampled, was 43.7 µg/L. The worst yearly average was 54.5 µg/L and the highest single sample was 120 µg/L, from 128 samples taken from 2012 to 2019.

For HAA5, the average in the last year sampled was 32 µg/L. The worst yearly average was 46.2 µg/L and the highest single sample was 202 µg/L, from 131 samples.

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 1.5 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, the highest was 1.34 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).

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.

"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 8 of 8 samples, highest 38.8 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 8 samples each.

Non-detects count as zero in the highest-result column.

Bacteria in the pipes

From 2012 to 2019, 2 of 1,924 routine total coliform samples taken in the distribution system at Steubenville, City Of tested positive (0.1%); in 2019, the last year on file, 1 of 242 did. E. coli was never found in the 1,499 samples 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 Steubenville, City Of adjusts the fluoride level to the recommended level for preventing tooth decay.

EPA's treatment table lists fluoridation among the steps at Steubenville, City Of.

Measured fluoride: 0.87 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.87 to 1.03 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 Steubenville, City Of, last sampled in 2023 (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.

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 1 time in 229 raw-water samples, across 1 bloom season (2025); the highest raw-water result was 0.249 µg/L on November 5, 2025. The highest raw-water result since 2024 was 0.249 µg/L.

Microcystin was never detected in treated water (89 samples).

In all, 318 samples from 2016 to 2026, the latest on August 19, 2026.

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 Steubenville, City Of 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 20,860 residents are inside the boundary, 123% of the 17,000 people Steubenville, City Of reports serving.

The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
