About this area's water Jackson Co. Water Company-wtp
Did you know
- Jackson County Water placed second in the state in the Ohio Rural Water Best Tasting Water Contest, per its 2024 report to customers.
- The company is a customer-owned cooperative governed by a nine-member volunteer Board of Trustees that meets at the business office on the third Monday of each month at 6 PM.
- It adds a sequestering additive and pays an independent lab to monitor the water's corrosivity, specifically so that lead and copper do not leach out of customers' own plumbing.
- Because so many customers live far off the road on long private service lines, the company gives out free toilet dye strips and includes leak insurance on customer accounts unless a customer cancels it.
- Until 2024 the company reported under three separate PWS numbers - 4002012, 4001803 and 4001903 - reflecting its own wells plus purchased water from Scioto Water Inc. and the Village of Oak Hill; 4001903 was folded into…

What the records show about Hamden Village
Who runs it
EPA's record describes Hamden Village as owned by a local government. It has 425 service connections and serves 970 people.
EPA classes it as a community water system, one that serves the same residents all year.
Source: EPA Safe Drinking Water Information System (SDWIS), water system record.
How the water is treated
Hamden Village buys water that Jackson Co. Water Company-wtp treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Jackson Co. Water Company-wtp: corrosion control, 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 counts 21 health-based violations for Hamden Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. They fall into 9 separate problems (one contaminant or rule in one year); the table lists the 8 most recent.
EPA logs a violation for each compliance period a problem lasts, so the count of 21 includes 12 repeat entries of the problems listed.
EPA logs 4 violations of any kind since 2020: 4 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 Hamden Village was 0.5 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 0.7 ppb, in the period ending June 2025.
EPA has 12 sampling periods on file for Hamden Village 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 Hamden Village sent EPA, 402 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 402 |
| All lines | 402 |
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 Hamden Village buys is treated by Jackson Co. Water Company-wtp, so the results below are Jackson Co. Water Company-wtp's.
EPA's fifth national round of testing (UCMR 5) took 2 samples of the water entering the pipes of Jackson Co. Water Company-wtp 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 Jackson Co. Water Company-wtp (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 Jackson Co. Water Company-wtp as sampled, most recently February 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 Hamden Village's samples in 2019, the last year it was sampled, was 50.8 µg/L. The worst yearly average was 84.6 µg/L and the highest single sample was 161 µg/L, from 68 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 39.5 µg/L. The worst yearly average was 63.9 µg/L and the highest single sample was 99.3 µg/L, from 68 samples. A yearly average over 60 is not itself a violation, because compliance is judged site by site.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 50.8 µg/L (2019) | 84.6 µg/L | 161 µg/L | 68 |
| HAA5 | 60 µg/L | 39.5 µg/L | 63.9 µg/L | 99.3 µg/L | 68 |
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 Hamden Village buys is treated by Jackson Co. Water Company-wtp, so the results below are Jackson Co. Water Company-wtp's.
Nitrate: the highest of 8 samples was 0.14 mg/L (as nitrogen) in 2016; in 2019, the last year sampled, the highest was 0.13 mg/L. 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).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | 0.14 mg/L | 10 mg/L | 0 |
| Arsenic | 3 | 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
The water Hamden Village buys is treated by Jackson Co. Water Company-wtp, so the results below are Jackson Co. Water Company-wtp's.
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 4 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 4 | 0 of 4 | 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
The water Hamden Village buys is treated by Jackson Co. Water Company-wtp, so the results below are Jackson Co. Water Company-wtp's.
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 2 of 3 samples, highest 60 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 3 samples each.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |

Bacteria in the pipes
From 2012 to 2019, 1 of 96 routine total coliform samples taken in the distribution system at Hamden Village tested positive (1.04%); in 2019, the last year on file, 0 of 12 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 Hamden Village buys its water from Jackson Co. Water Company-wtp, 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 Jackson Co. Water Company-wtp, which treats the water Hamden Village buys.
Measured fluoride: 0.14 mg/L on average leaving the plants of Jackson Co. Water Company-wtp, which supplies Hamden Village, in 2018 (too little to protect teeth); samples ran from 0.12 to 1.03 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 Jackson Co. Water Company-wtp, which supplies Hamden Village, 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.
