CDC's My Water's Fluoride listing does not report this system as fluoridating its drinking water.
Per CDC My Water's Fluoride · See details below
Past 5 years: 3 health-based violations on file, all marked Resolved or Archived. See compliance history below.
Risk classification follows EPA's published values for safe drinking water, with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this card. See methodology.
Lead service line inventory
Utility reports no confirmed lead service lines
DOBBIN PLANTERSVILLE WSC 1 reports 0 confirmed lead service lines, 1,228 non-lead, 0 unknown (total 1,228) in the EPA SDWIS service line inventory (2026Q1).
- 0 confirmed lead service lines
- 0 galvanized requiring replacement (LCRI treats these as lead)
- 0 unknown (0.0% of total)
- 1,228 confirmed non-lead (100.0%)
- 1,228 total service lines in the system
What to do if your service line might be lead
- Ask your utility to check the service-line classification for your specific address. Many utilities provide a public address-lookup tool linked from the inventory page.
- Get on the replacement queue. Under the LCRI, utilities must replace all lead and galvanized-requiring- replacement lines within 10 years (clock generally starts November 2027). Some prioritize requests.
- Until the line is replaced: flush the tap 30 seconds after long stagnation, use cold water for drinking and cooking, and consider an NSF/ANSI 53 lead-rated tap filter.
- Talk to your clinician about a blood lead test for anyone in the home, especially a pregnant person or a child under 6. Lead in drinking water guide.

Lead and copper test results
The most recent measurement per contaminant from EPA's Lead and Copper Rule sampling.
Why only lead and copper, and not arsenic, nitrate, or others?
EPA's bulk SDWIS download is the only nationwide per-system sample data they publish, and it only includes the Lead and Copper Rule table. Values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) appear on this page only when they trigger a violation. For the full per-system contaminant suite, see the utility's annual Consumer Confidence Report (link further down the page).
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0 mg/L | June 30, 2024 | Below regulatory thresholds |
Data from EPA SDWIS (Lead and Copper Rule sample table) , last refreshed May 24, 2026.
PFAS and emerging contaminants
This system was tested 90 times under EPA's latest PFAS monitoring program; 1 of the 30 chemicals tested was detected.
What is this testing program?
EPA's fifth Unregulated Contaminant Monitoring Rule cycle (UCMR 5, 2023 to 2025) required every public water system serving over 3,300 people to test for 29 per- and polyfluoroalkyl substances (PFAS) plus lithium; 30 chemicals in total. Most recent detection per chemical shown below.
| Contaminant | Most recent detection | Date | Risk |
|---|---|---|---|
| 0.0295 mg/L | June 16, 2025 | Caution |
Tested but not detected (29 contaminants)
EPA tested for these substances and every sample was below the minimum reporting level. Absence of detection does not mean true zero; it means below the laboratory's quantitation threshold.
Data from EPA UCMR 5 (Unregulated Contaminant Monitoring Rule) , last refreshed May 24, 2026.
Fluoride
Per CDC My Water's Fluoride
DOBBIN PLANTERSVILLE WSC 1 does not add fluoride to its drinking water.
This system has not reported adding fluoride to its water on CDC's My Water's Fluoride listing. Natural fluoride may still be present at trace levels from the source water; the utility's annual water quality report has the latest measured concentration.

Recorded contaminant measurements (from violations)
When this system exceeded a regulatory limit and EPA recorded the measured value, that value is shown here. These are not routine sample results: they are the values the violation was triggered on.
| Period | Contaminant | Measured | Federal MCL | Status |
|---|---|---|---|---|
| July 1, 2025 | Tthm | 0.086MG/L | 0.08 MG/L | Health-based |
| July 1, 2025 | Tthm | 0.086MG/L | 0.08 MG/L | Health-based |

Compliance history
EPA-recorded violations against this system over the last 5 years.
How to read this section
Health-based violations are when a measured limit was exceeded; the measured concentration is shown alongside the EPA federal limit where SDWIS published it. Monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.
3 resolved health-based violations in the last 5 years
All 3 health-based violations in the last 5 years are marked Resolved or Archived. Past violations do not represent current water quality.

Where to see every contaminant this utility tested for
EPA's bulk SDWIS dataset gives MyTapWater.us per-system measured values for lead and copper, plus violation records for everything else. To see every regulated contaminant this utility tested for in the past year (TTHMs, HAA5, nitrate, arsenic, fluoride, chromium, etc.) with measured values, read the utility's Consumer Confidence Report (CCR).
Every community water system is required by EPA to publish a CCR annually, by July 1, listing every contaminant they sampled, the measured value, the federal limit, and any health-based exceedances. Most utilities post the report online; some mail it with your bill.
How to find DOBBIN PLANTERSVILLE WSC 1's CCR:
- Search the web for "DOBBIN PLANTERSVILLE WSC 1 consumer confidence report" . The PDF is usually on the utility's own website.
- Or call the utility directly. Their phone number is in the contact section below.
