About this area's water
Did you know
- New Philadelphia's wells have carried industrial solvents since 1981, and the plant aerates the raw water specifically to blow those volatile organic compounds off before it reaches customers - trichloroethylene was…
- The water table in the city's wellfield sits only 10 to 15 feet below the ground surface under thin, permeable sandy loam, which is why Ohio EPA rates the source highly susceptible to contamination.
- The city softens its water by ion exchange before you get it, and still reports 111 ppm hardness (6.49 grains per gallon) at an average pH of 7.8.
- All 4 million gallons of the city's water storage sits in three steel standpipes - 0.5, 1.5 and 2 million gallons - rather than in elevated towers.
- The city's 2024 notice of violation was for what its water quality report left out, not for anything in the water: it had omitted the wellfield susceptibility report and its license-to-operate status. The 2025 report…
History5
- 1981Volatile organic compounds first detected in the city's distribution system; the existing groundwater supply has required VOC treatment ever since.
- 1987Aeration proposed as the means of stripping VOCs out of the well water, and it remains part of the treatment train today.
- 2023City participates in the fifth Unregulated Contaminant Monitoring Rule round (April and October sampling), turning up only trace PFAS.
- 2024City receives a notice of violation over its published water quality report, for omitting the wellfield susceptibility report and license-to-operate status and for two table-formatting problems. This…
- 2025City issued a green unconditional license to operate; no regulatory testing exceeded any MCL during the year.

EPA compliance record
Lead at the tap: 90th-percentile result 1.4 ppb in 2024 (action level 15 ppb).
EPA record: no health-based violations since 2015.
2 violations of any kind logged 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).
Supply stress
Ohio EPA continues to assign New Philadelphia's drinking water source a HIGH susceptibility to contamination, for four stated reasons: a thin, highly permeable sandy loam soil layer that offers little protection from spills at the surface; a water table generally only 10 to 15 feet below ground in the sand and gravel aquifer; largely…
Sewers
Sanitary
The city operates its own wastewater treatment plant at 1422 Delaware Drive SE, using biological treatment, disinfection and sludge processing, and reports removing 90-95% of organic material and suspended solids to meet Ohio EPA standards. Collection is by gravity sewer plus 14 lift stations serving low-lying areas. The city does not…
Storm
New Philadelphia states it runs a fully separate sanitary and storm sewer system, so stormwater does not enter the wastewater plant; the city credits this with preventing overflows. No separate stormwater utility fee appears on the 2026 rate sheet, which…

What the records show about New Philadelphia City
Who runs it
EPA's record describes New Philadelphia City as owned by a local government. It has 8,199 service connections and serves 17,410 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 330-339-3795.

How the water is treated
EPA's treatment table registers these steps for New Philadelphia City: aeration, corrosion control, chlorine disinfection, iron and manganese removal, and ion-exchange softening.
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 New Philadelphia 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 2024, the 90th-percentile lead result at New Philadelphia City was 1.4 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 2.7 ppb, in the period ending December 2018.
EPA has 3 sampling periods on file for New Philadelphia City 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 New Philadelphia City sent EPA, 8,386 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 347 |
| Unknown material | 7,185 |
| Not lead | 854 |
| All lines | 8,386 |
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 3 samples of the water entering the pipes of New Philadelphia City 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 New Philadelphia City (latest sample July 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 New Philadelphia City as sampled, most recently July 2026.
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 New Philadelphia City's samples in 2019, the last year it was sampled, was 2.8 µg/L. The worst yearly average was 19 µg/L and the highest single sample was 19 µg/L, from 37 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 2.7 µg/L. The worst yearly average was 4.2 µg/L and the highest single sample was 10.2 µg/L, from 37 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 2.8 µg/L (2019) | 19 µg/L | 19 µg/L | 37 |
| HAA5 | 60 µg/L | 2.7 µg/L | 4.2 µg/L | 10.2 µg/L | 37 |
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 0.8 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, the highest was 0.69 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic: the highest of 3 samples was 2.3 µg/L (limit 10); detections averaged 2; none over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | 0.8 mg/L | 10 mg/L | 0 |
| Arsenic | 3 | 2.3 µg/L | 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. trichloroethylene (TCE) was detected in 4 of 38 samples, highest 9.3 µg/L (limit 5, 1 over); tetrachloroethylene (PCE) was detected in 2 of 38 samples, highest 1.5 µg/L (limit 5). Benzene, carbon tetrachloride, 1,2-dichloroethane, and vinyl chloride were not detected in 38 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 38 | 0 of 38 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 38 | 0 of 38 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 38 | 0 of 38 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 38 | 4 of 38 | 9.3 µg/L | 1 |
| Tetrachloroethylene (PCE) | 5 µg/L | 38 | 2 of 38 | 1.5 µg/L | 0 |
| Vinyl chloride | 2 µg/L | 38 | 0 of 38 | 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.

Bacteria in the pipes
From 2012 to 2019, 1 of 1,771 routine total coliform samples taken in the distribution system at New Philadelphia City tested positive (0.06%); in 2019, the last year on file, 0 of 241 did. E. coli was never found in the 1,455 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 New Philadelphia City 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 0.22 mg/L.
EPA's treatment table lists no fluoridation step at New Philadelphia City.
Measured fluoride: none was detected in 3 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.

Lithium
Lithium was not detected in 2 UCMR 5 samples at New Philadelphia City, 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.
