About this area's water Hebron Village
Did you know
- Hebron's original business district was destroyed by a fire around the turn of the 20th century, before the village had piped water for firefighting.
- The village's first water system in 1937 served only 84 customers; the system now has 870 service connections.
- Hebron's water reclamation plant uses an 'Orbal oxidation ditch' -- a racetrack-shaped biological treatment loop -- ahead of tertiary sand filtration and UV disinfection, replacing an older 1960s plant that was…
- Hebron's 2025 water-quality testing, including its first round of PFAS screening under the new federal rule, came back non-detect or well under federal limits across every parameter listed in its CCR.
History5
- 1935-1937Negotiations for a village water system began in 1935; pumping to the first 84 customers started in 1937.
- 1952-1964Village pursued legislation for sewers and enlarged water facilities, which became operational by 1964.
- 1983-1989Water/sewer system expanded twice, eventually growing to serve well over 700 users (today 870 service connections).
- 2005Ohio EPA source water assessment reportedly rated Hebron's aquifer 'LOW' susceptibility to contamination (per the village's own site).
- 2006Village's Water Reclamation Facility began operation on November 10, 2006, replacing an overloaded 1963-64 plant, discharging to Beaver Run.

How the water is treated
Licking County Harbor Hills buys water that Hebron Village treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Hebron Village: aeration, coagulation and settling, chlorine disinfection, fluoridation, lime 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 Licking County Harbor Hills 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 Licking County Harbor Hills 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.
EPA has 6 sampling periods on file for Licking County Harbor Hills 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 Licking County Harbor Hills sent EPA, 568 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 327 |
| Not lead | 241 |
| All lines | 568 |
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
The water Licking County Harbor Hills buys is treated by Hebron Village, so the results below are Hebron Village's.
Ohio EPA's own statewide sampling tested 1 plant of Hebron Village (latest sample October 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 Hebron Village as sampled, most recently May 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 Licking County Harbor Hills's samples in 2019, the last year it was sampled, was 47.7 µg/L. The worst yearly average was 95.7 µg/L and the highest single sample was 98 µg/L, from 51 samples taken from 2012 to 2019. A yearly average over 80 is not itself a violation, because compliance is judged site by site.
For HAA5, the average in the last year sampled was 9.2 µg/L. The worst yearly average was 9.8 µg/L and the highest single sample was 11.9 µg/L, from 51 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 47.7 µg/L (2019) | 95.7 µg/L | 98 µg/L | 51 |
| HAA5 | 60 µg/L | 9.2 µg/L | 9.8 µg/L | 11.9 µg/L | 51 |
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
The water Licking County Harbor Hills buys is treated by Hebron Village, so the results below are Hebron Village's.
Nitrate: the highest of 8 samples was 0.12 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, nitrate was not detected. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic: the highest of 34 samples was 4.8 µg/L (limit 10); detections averaged 3.7; none over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | 0.12 mg/L | 10 mg/L | 0 |
| Arsenic | 34 | 4.8 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.

Fluoride
The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Licking County Harbor Hills buys its water from Hebron Village, a system that adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at Hebron Village, which treats the water Licking County Harbor Hills buys.
Measured fluoride: 0.94 mg/L on average leaving the plants of Hebron Village, which supplies Licking County Harbor Hills, in 2018 (in the range dentists aim for); samples ran from 0.9 to 0.95 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.
