How the water is treated

EPA's treatment table registers these steps for Scioto Water Inc.-rose Hill: aeration, chlorine disinfection, iron and manganese removal, fluoridation, ion-exchange softening, 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 Scioto Water Inc.-rose Hill 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 2025, the 90th-percentile lead result at Scioto Water Inc.-rose Hill was 4.6 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.

EPA has 8 sampling periods on file for Scioto Water Inc.-rose Hill since 2016, the first ending in 2018; 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 Scioto Water Inc.-rose Hill sent EPA, 4,790 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 2 samples of the water entering the pipes of Scioto Water Inc.-rose Hill 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 Scioto Water Inc.-rose Hill (latest sample June 2020). 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 Scioto Water Inc.-rose Hill's samples in 2019, the last year it was sampled, was 8 µg/L. The worst yearly average was 26.9 µg/L and the highest single sample was 30.2 µg/L, from 44 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 12.2 µg/L, from 45 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 8 samples was 1.97 mg/L (as nitrogen), in 2019, the last year sampled. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.

Arsenic was not detected in 3 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 3 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 3 of 3 samples, highest 29 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 3 samples each.

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

Bacteria in the pipes

From 2012 to 2019, 0 of 963 routine total coliform samples taken in the distribution system at Scioto Water Inc.-rose Hill 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 Scioto Water Inc.-rose Hill adjusts the fluoride level to the recommended level for preventing tooth decay.

EPA's treatment table lists fluoridation among the steps at Scioto Water Inc.-rose Hill.

Measured fluoride: 0.92 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.92 to 1.07 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 not detected in 2 UCMR 5 samples at Scioto Water Inc.-rose Hill, 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.

How well the service area is mapped

EPA estimated the service area of Scioto Water Inc.-rose Hill 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 1,281 residents are inside the boundary, 14% of the 8,861 people Scioto Water Inc.-rose Hill reports serving. With so much of its territory outside the polygon, part of the system shows on the map as private wells.

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