How the water is treated
Switzer Water Association buys water that Clarington Village treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Clarington Village: chlorine disinfection.
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 Switzer Water Association since 2015.
EPA logs no violations of any kind for Switzer Water Association since 2020.

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Switzer Water Association was 1.6 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 3.8 ppb, in the period ending December 2024.
EPA has 9 sampling periods on file for Switzer Water Association since 2016, the first ending in 2016; 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 Switzer Water Association sent EPA, 784 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 784 |
| All lines | 784 |
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 Switzer Water Association buys is treated by Clarington Village, so the results below are Clarington Village's.
Ohio EPA's own statewide sampling tested 1 plant of Clarington Village (latest sample May 2021). The highest result was PFHxS at 10.1 ppt (ppt is the same unit as ng/L), against Ohio's action level of 140 ppt. The highest PFOA or PFOS result was PFOS at 10.1 ppt, against 70 ppt. Those action levels are the ones Ohio EPA used for the survey; the 2024 federal limit for PFOA and PFOS is 4 ng/L.
Ohio EPA's current sampling status map lists 1 plant of Clarington Village as sampled, most recently August 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 Switzer Water Association's samples in 2019, the last year it was sampled, was 8 µg/L. The worst yearly average was 9.1 µg/L and the highest single sample was 9.5 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 | 8 µg/L (2019) | 9.1 µg/L | 9.5 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.

Nitrate, arsenic and radioactivity
The water Switzer Water Association buys is treated by Clarington Village, so the results below are Clarington Village's.
Nitrate: the highest of 14 samples was 7.8 mg/L (as nitrogen) in 2012; in 2019, the last year sampled, the highest was 2.83 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) | 14 | 7.8 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 Switzer Water Association buys is treated by Clarington Village, so the results below are Clarington Village'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 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.

Bacteria in the pipes
From 2012 to 2019, 0 of 192 routine total coliform samples taken in the distribution system at Switzer Water Association tested positive (0%); in 2019, the last year on file, 0 of 24 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 Switzer Water Association buys its water from Clarington Village, 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 0.08 mg/L.
EPA's treatment table lists no fluoridation step at Clarington Village, which treats the water Switzer Water Association buys.
Measured fluoride: none was detected in 3 samples leaving the plants of Clarington Village, which supplies Switzer Water Association, 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.
