What the records show about Crestline Village
Who runs it
EPA's record describes Crestline Village as owned by a local government. It has 2,108 service connections and serves 4,525 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 419-683-3800.

How the water is treated
EPA's treatment table registers these steps for Crestline Village: aeration, chlorine disinfection, iron and manganese removal, 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 Crestline 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 2024, the 90th-percentile lead result at Crestline Village was 3.3 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 4 ppb, in the period ending December 2017.
EPA has 4 sampling periods on file for Crestline Village since 2016, the first ending in 2017; 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 Crestline Village sent EPA, 1,985 lines are counted.
| Material | Lines |
|---|---|
| Lead | 78 |
| Galvanized, needing replacement | 26 |
| Unknown material | 1,521 |
| Not lead | 360 |
| All lines | 1,985 |
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 Crestline Village 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 Crestline Village (latest sample October 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 Crestline Village's samples in 2019, the last year it was sampled, was 13.1 µg/L. The worst yearly average was 15.5 µg/L and the highest single sample was 22.4 µg/L, from 14 samples taken from 2013 to 2019.
For HAA5, the average in the last year sampled was 0 µg/L. The worst yearly average was 0 µg/L and the highest single sample was 0 µg/L, from 14 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 13.1 µg/L (2019) | 15.5 µg/L | 22.4 µg/L | 14 |
| HAA5 | 60 µg/L | 0 µg/L | 0 µg/L | 0 µg/L | 14 |
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.
Source: EPA Six-Year Review 4 compliance monitoring data, 2012 to 2019, distribution-system samples (non-detects counted as zero).
Nitrate, arsenic and radioactivity
Nitrate was not detected in 8 samples through 2019 (limit 10 mg/L as nitrogen; above 10 is unsafe for infants).
Arsenic was not detected in 5 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | not detected | 10 mg/L | 0 |
| Arsenic | 5 | 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 2 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 2 | 0 of 2 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 2 | 0 of 2 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 2 | 0 of 2 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 2 | 0 of 2 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 2 | 0 of 2 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 2 | 0 of 2 | 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 2 of 2 samples, highest 75 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 2 samples each.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |

Bacteria in the pipes
From 2012 to 2019, 0 of 541 routine total coliform samples taken in the distribution system at Crestline Village tested positive (0%); in 2019, the last year on file, 0 of 60 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 Crestline Village buys its water from Galion City, a system that 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 0.18 mg/L.
EPA's treatment table lists no fluoridation step at Crestline Village.
Measured fluoride: 0.26 mg/L on average at the plant's entry points in 2017 (too little to protect teeth); samples ran from 0.26 to 0.29 mg/L across 2 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 found in 2 of 2 UCMR 5 samples at Crestline Village, highest 24 µg/L; detections averaged 23.6, last sampled in 2023.
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.
