Public water system profile

BARNWELL TOWN OF

The City’s 2025 report for SC0610001 lists seven results from 2023–2025 samples. Read each result with its own period, unit, and printed benchmark; the report does not describe a particular tap today.

EPA Version 3 returned one PWSID-matched multipolygon for SC0610001. EPA identifies it as an Office of Research and Development Random Forest model for a Residential Area; it is geographic context, not a utility- or state-certified service boundary. Confirm service with your bill or utility account.

System facilities

How does Barnwell source and treat its water?

The City’s 2025 report describes groundwater wells, chlorine disinfection, and two elevated tanks. It does not identify the well serving a home or establish current facility status.

Groundwater source

The report says Barnwell drinking water comes from wells tapped into an underground aquifer system. It states five wells but prints six well-number entries; that count discrepancy is preserved, not resolved.

Report pages 1–2; the source wording difference remains open.

Treatment and storage

The report describes chlorine disinfection and lists two elevated tanks in its system context. The 2025 chlorine row is shown in the complete table below; neither statement establishes current operation.

Report pages 1–4; facility inventory completeness was not independently established.

Source: City of Barnwell 2025 CCR. No separate accepted source-water assessment, wellhead-protection plan, corrosion-control record, or fluoridation record was found in the reviewed packet.

Report results

Results in the City’s 2025 report

These are the seven rows printed for SC0610001. Check each sample period: the report includes 2023 and 2024 tests as well as 2025 results.

How to read these results

The chlorine row reports 0.4 ppm for its 2025 sample period, with a range of 0.28–0.47 ppm. The printed benchmark is an MRDL of 4 ppm (maximum residual disinfectant level). “2025” is the CCR’s report year; a separate publication date was not verified. Barium, lead, and copper use 2023 sample periods, so the cover year is not every test date.

“Violation: No” is the report’s printed status for this chlorine row and period. Comparing 0.4 with 4 does not establish current compliance, household exposure, or tap-water safety. This report does not identify a separate supplier-result table; results from another system should not be treated as SC0610001 samples.

Some printed cells need care: sodium has no MCL value in the source; its typical-source phrase ends at “Leaching.” The radium and lead MCLG cells print “00.” The copper row prints one sample above the action level but also says “Exceeds AL: No.” Those differences are shown as printed, not resolved on this page. The lead typical-source cell continues from PDF page 4 onto page 5.

Lead and copper

What did 2023 lead and copper tap sampling report?

Report notes

What the report does—and does not—say

The report prints a Violations and Exceedances heading with no entries beneath it. That is not a live check for notices or regulatory status.

Is a complete violation history available here?

No separate PWSID-bound violation, enforcement, waiver, or sanitary-survey history was accepted for this page. The empty heading on PDF page 5 is only a feature of the 2025 report; it cannot establish that no current violation or notice exists.

MCLG
MCLG: Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
MCL
MCL: Maximum Contaminant Level: The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
TT
TT: Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water.
AL
AL: Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Variances and Exemptions
Variances and Exemptions: State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
MRDLG
MRDLG: Maximum residual disinfection level goal. The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
MRDL
MRDL: Maximum residual disinfectant level. The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
MNR
MNR: Monitored Not Regulated
MPL
MPL: State Assigned Maximum Permissible Level
90th Percentile
Compliance with the lead and copper action levels is based on the 90th percentile lead and copper levels. This means that the concentration of lead and copper must be less than or equal to the action level in at least 90% of the samples collected.

Unanswered questions

What is still unconfirmed for SC0610001?

The 2025 report supplies dated results, but it does not answer every service, regulatory, or household question.

System history and service

  • Address-level service-area or provider-lookup record.
  • Separate 2024, 2023, and older annual reports; none was located in the reviewed official archive, and nonpublication was not established.
  • Structured violations, enforcement, waivers, sanitary surveys, and current-notice coverage.
  • Source-water assessment, wellhead protection, corrosion-control, fluoridation, and hardness records.

Household and infrastructure details

  • Dated lead-service-line inventory totals or replacement program.
  • PFAS/UCMR, school or public-building testing, and household sample-request terms.
  • Capital projects, flushing or construction schedules, and current drought-stage details.

For a current notice, check City news and announcements. To confirm service, rates, or a household question, use the City Water & Sewer page or call803-259-3266. These links are contact paths, not confirmation that a missing record exists.
