About this area's water
Did you know
- Lodi sits on the north-south continental divide: rain falling on the village runs off either north to Lake Erie or south to the Ohio River. The East Fork of the Black River enters from the north, turns back north, and…
- The village was founded in 1811 as Harrisville, for Judge Joseph Harris, and is the oldest settlement in Medina County; the name Lodi echoes Napoleon's 1796 victory at Lodi in northern Italy.
- EPA's facility inventory lists the Bank Street tank as inactive - which is the opposite of the frequently repeated claim that it is the village's oldest tank still in service. The active storage is the Evergreen…
- Lodi's 90th-percentile lead has stayed between 1.2 and 1.7 ppb across four straight monitoring rounds since 2016, roughly a tenth of the 15 ppb action level.

EPA compliance record
Lead at the tap: 90th-percentile result 1.7 ppb in 2025 (action level 15 ppb).
EPA record: no health-based violations since 2015.
1 violation of any kind logged since 2020: 1 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
EPA records show the system carries a source water protection plan, with a protection period beginning September 29, 2025.
Sewers
Sanitary
The village operates the Lodi WWTP, NPDES permit OH0020991, at 300 Grandview Avenue, with a total design flow of 0.8 MGD; the current individual permit took effect April 1, 2023.

What the records show about Lodi Village
Who runs it
EPA's record describes Lodi Village as owned by a local government. It has 1,800 service connections and serves 2,884 people.
EPA classes it as a community water system, one that serves the same residents all year.
EPA's record says it has substantially implemented source water protection under Ohio's program, dating the program from 2025. Its office telephone on EPA's record is 330-948-2892.

How the water is treated
EPA's treatment table registers these steps for Lodi Village: corrosion control, chlorine disinfection, iron and manganese removal, fluoridation, 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 Lodi Village since 2015.
EPA logs 1 violation of any kind since 2020: 1 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 Lodi Village was 1.7 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
EPA has 4 sampling periods on file for Lodi 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 Lodi Village sent EPA, 1,126 lines are counted.
H2Ohio paid the Rural Community Assistance Partnership to help this small system build its lead service line inventory (Ohio EPA).
| Material | Lines |
|---|---|
| Lead | 4 |
| Galvanized, needing replacement | 32 |
| Unknown material | 576 |
| Not lead | 514 |
| All lines | 1,126 |
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
Ohio EPA's own statewide sampling tested 1 plant of Lodi Village (latest sample August 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 Lodi Village's samples in 2019, the last year it was sampled, was 23.6 µg/L. The worst yearly average was 39.7 µg/L and the highest single sample was 51.3 µg/L, from 15 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 4.3 µg/L. The worst yearly average was 16.9 µg/L and the highest single sample was 16.9 µg/L, from 15 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 23.6 µg/L (2019) | 39.7 µg/L | 51.3 µg/L | 15 |
| HAA5 | 60 µg/L | 4.3 µg/L | 16.9 µg/L | 16.9 µg/L | 15 |
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 was not detected in 9 samples through 2019 (limit 10 mg/L as nitrogen; 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) | 9 | not detected | 10 mg/L | 0 |
| Arsenic | 3 | not detected | 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. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 3 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 3 | 0 of 3 | 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
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 3 of 3 samples, highest 18.2 µg/L (limit 2,000). Not detected: atrazine in 5 samples, alachlor in 5 samples, chromium in 3 samples, cadmium in 3 samples, mercury in 3 samples, selenium in 3 samples, thallium in 3 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 5 | 0 of 5 | not detected | 0 |
| Alachlor | Farm chemical | 2 µg/L | 5 | 0 of 5 | not detected | 0 |

| Selenium | Metal | 50 µg/L | 3 | 0 of 3 | not detected | 0 |
| Thallium | Metal | 2 µg/L | 3 | 0 of 3 | not detected | 0 |
Non-detects count as zero in the highest-result column.

Bacteria in the pipes
From 2012 to 2019, 1 of 445 routine total coliform samples taken in the distribution system at Lodi Village tested positive (0.22%); in 2019, the last year on file, 0 of 48 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 Lodi Village adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at Lodi Village.
Measured fluoride: 0.96 mg/L on average at the plant's entry points in 2018 (in the range dentists aim for); samples ran from 0.79 to 0.96 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.

How well the service area is mapped
EPA estimated the service area of Lodi Village 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 2,780 residents are inside the boundary, 96% of the 2,884 people Lodi Village reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
