Report Context
Context attributed to the source report
These summaries are limited to the named annual report and do not assert live system, compliance, or advisory status.
Report and sampling periods
The Town of Silver City's 2025 Water Quality Report says it covers monitoring sampling performed from January through December 2025. Copper, Lead, and Lithium rows print a 2023 sample year, while the customer-interest table does not print a sampling year. These are report-period records, not live conditions.
Complete printed result-table coverage
The 21 structured rows cover every row in the six printed result tables reviewed in this report: the customer-interest, water-quality analysis, disinfectants/by-products, Lead and Copper, Microbiological, and UCMR5 Lithium tables. This does not claim complete coverage of every possible laboratory result or current condition.
Source water described in the report
The 2025 report describes groundwater from Frank's Well Field, Woodward Well Field, and the Gabby Hayes Well, drawing from the Gila-San Francisco and Mimbres water basins. This is report-period source context, not a current well-operating inventory.
Source Water Assessment and Protection context
The report says the Source Water Assessment and Protection program assigned the system a high susceptibility ranking based on information collected during the assessment. The report does not state the assessment date. Susceptibility describes potential contamination and is not a detection, violation, current advisory, or safety conclusion.
Lead and service-line context in the report
The report says the Town developed a lead and copper service line inventory in 2024 and associates lead with service lines and home plumbing. The 2023 system-level Lead row does not identify the material or condition of any specific tap or service line. Confirm current inventory availability, testing guidance, and exposure-reduction information with the Town and current EPA guidance.
Definitions printed in this report
These 12 definitions are reproduced from the named report. A definition does not expand a row's scope; the source's ND definition applies only to the field and sampling period where ND is printed on this page.
UCMR5 Lithium and PFAS scope in the report
The report says the system was sampled for Lithium and PFAS under EPA's Fifth Unregulated Contaminant Monitoring Rule on June 5, 2023 and says only Lithium was detected in that sampling. The table prints a Lithium row but no PFAS rows or values. The no-standard wording printed for Lithium is not adopted as a current regulatory-status conclusion.
Spanish-access notice in the report
The 2025 report includes a Spanish-access notice directing readers to the Town Utilities Department. Confirm current availability and contact details through the Town's current water-reports page.
Printed status cells remain report-period evidence
The source prints YES for 12 rows and N/A for Lithium under MEETS EPA STD or MEETS EPA STANDARDS. Those cells remain scoped to the named row and printed sample/report period; they do not establish current system-wide compliance, no-violation, safety, or advisory status.
Definitions printed in this report
- 90th Percentile
- Out of every 10 homes sampled, 9 were at or below this level.
- AL (Action Level)
- The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
- MCL (Maximum Contaminant Level)
- The highest level of a contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
- MCLG (Maximum Contaminant Level Goal)
- The level of a contaminant in drinking water below which there is no known or expected risk of health. MCLGs allow for a margin of safety.
- MRDL (Maximum Residual Disinfectant Level)
- The highest level of chlorine residual allowed in drinking water.
- MRDLG (Maximum Residual Disinfectant 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.
- ND (Non-Detects)
- Not detected; Contaminant is not present.
- pCi/L (Picocuries per liter)
- A measurement of radioactivity in water.
- Ppb (Parts per billion)
- One part substance per billion parts water or 1 minute in 2,000 years.
- Ppm (Parts per million)
- One part substance per million parts water or 1 minute in 2 years.
- RAA (Running Annual Average)
- The average sample analytical results for samples taken during the last 12 calendar months.
- TT (Treatment Technique)
- A required process intended to reduce the level of contaminants in drinking water.

Source-period disclosures kept separate from live status
These items preserve report wording and scope. They do not create violation records, advisory records, or a current-status conclusion.
Violation and advisory scope
No separate violation or advisory section appears in the six-page PDF reviewed for this summary. That reviewed source absence is not a claim that the system has no violations, no advisory, or current compliance. Check current official Town and state notices.
Current status is not asserted. Check official current sources for notices or instructions.

Report identity and field provenance
- Official report document: Town of Silver City 2025 Water Quality Report Verified as a six-page PDF with SHA-256 6d4ef897d7cc2c6a1565b7b99aecd541168b1352b766edff2ba852eb793b5c1c.
- Town report identity: Town of Silver City Water Reports The Town page served as the original report-discovery path. Its 2026-07-10 HTML no longer exposed document 3238, while the direct Town-hosted PDF remained available and supplied the Town/report identity but did not print a PWSID.
- PWSID NM3522609: NMED Drinking Water Watch system detail The official state record identifies NM3522609 as SILVER CITY WATER SYSTEM. The PDF does not print this PWSID, and the state inventory status is not treated as current compliance, safety, or advisory evidence.
- Report year and monitoring period: Town of Silver City 2025 Water Quality Report The PDF identifies 2025 and says it covers monitoring sampling performed from January through December 2025; individual rows retain their printed 2023 or 2025 sample years, and the customer-interest table prints no year.
