System identity and sources
Springfield Water and Sewer Commission · PWSID 1281000
System-specific source and provider context for the assigned public water system.
MassDEP identity
The current state record identifies Springfield Water And Sewer Commission as the active community water system associated with PWSID 1281000. It does not establish address-level or exclusive service.
Source-water context
The provider describes a surface-water system, Little River Watershed protection, and a Ludlow emergency-supply context. These are attributed source records, not household-source assignments.
Provider confirmation
Confirm a particular address with a bill, account, the Commission, or MassDEP. City navigation does not prove service.
Read the Springfield city orientation →Sources checked : MassDEP identity, source-water protection, and system description.
Service relationship
Regional provider context, without an address-level service claim
The Commission’s public materials describe service beyond a single city boundary; the exact relationship for an address still needs confirmation.
What the reviewed sources establish
Commission materials describe retail service in Springfield and Ludlow and a broader regional treatment footprint. That supports system context but does not identify every connected property, wholesaler, consecutive system, or interconnection direction.
What the mapped boundary does not establish
A modeled boundary is not an address lookup. It does not prove a connection, identify a private-well property, or establish a wholesale, consecutive, purchased-water, or interconnection direction.
Next action: confirm an address-specific provider path with the Commission, MassDEP, or the customer’s utility account.

Official HAA5 notice:
On July 2, 2026, the Springfield Water and Sewer Commission issued an HAA5 maximum contaminant level violation notice for PWSID 1281000. The notice's Quarter 2 2026 table shows six of eight 12-month locational running annual averages above the 60 ppb maximum contaminant level. The notice states that this is not an emergency and includes the provider's official instructions and health-specific guidance. This dated notice is separate from the 2025 annual-report rows below.

Population scope: MassDEP lists 169,170 people and 43,302 service connections for PWSID 1281000. EPA's federal record lists 234,105 people, while the Commission describes service to more than 250,000 customers across its broader regional treatment footprint. Scope and update timing may differ, so these figures should not be treated as interchangeable.
A notice destination does not determine a household tap condition.
Treatment and facilities
Provider-described treatment infrastructure
Dated provider pages identify the facility and project context; they do not replace a current operating record.
West Parish
The Commission publishes a New Water Plant page for its West Parish treatment infrastructure. The page is retained as facility and project evidence, not as a claim about every current process.
Disinfection byproducts
The Commission’s DBP FAQ explains provider context for HAA5 and related disinfection byproducts. The 2025 report rows preserve their own period, units, limits, and printed status.
Open treatment questions
Current corrosion-control and fluoridation status are not asserted until a dated system-specific source is verified.
Sources: West Parish project, DBP FAQ, and the 2025 report.

Historical report boundary: The seven-page report covers 2025 testing and separately describes older lead-and-copper sampling. Its result cells and provider statements remain historical annual-report evidence, not live compliance, advisory, safety, exposure, address-level, household, or tap conclusions. (PDF page 1.)
Report-period HAA5 notice context remains separate: The report says the Commission issued four quarterly public notices in 2025 for HAA5 MCL exceedances and describes an April 22, 2024 Administrative Consent Order. Those source-period statements and the system profile's separately reviewed 2026 provider notice paths are not converted into a current notice, current advisory, or current water-safety conclusion here. (PDF page 3.)
Lead and service-line context remains report scoped: The report's source-water, treatment, plumbing, lead, service-line inventory, replacement, household-action, testing, health, and contact statements remain attributed report-period context. They do not establish a service-line material, household condition, exposure, or tap result for any address. (PDF page 6.)
System preview remains unchanged: All 22 result rows remain attached to the historical report. The Springfield system profile keeps exactly its existing HAA5 then Nitrate preview row objects, values, ranges, criteria, source order, July 2026 retrieval dates, source notes, limitations, and contaminant selection. (PDF page 5.)
Complete visual review: all seven PDF pages were reviewed. Source checksum and extraction manifest are retained in the repository evidence dossier. This section does not convert historical report values into current compliance, safety, exposure, advisory, or household-tap conclusions.

Monitoring and lead context
Report-scoped monitoring, with unresolved system topics visible
The complete report section contains the lead/copper and location-specific rows. Other monitoring programs remain evidence-limited until exact system records are reconciled.
Lead and copper
The 2025 report extraction preserves the lead-and-copper table and its printed sample-period context. It does not describe every tap or a property’s service line.
Service-line source
The Commission’s lead page is the official destination for service line and school-testing context. A PWSID-scoped inventory count is not asserted until separately verified.
Open lead and drinking-water informationPFAS and UCMR
No exact-PWSID PFAS or UCMR result set is rendered in this campaign. This is an evidence gap, not a non-detection or compliance result.
Facilities and customer operations
Infrastructure, billing, and assistance sources
Official provider destinations are separated from report measurements and current-status conclusions.
Facilities

Unfinished evidence is shown instead of silently omitted
These topics remain evidence-limited or blocked in the Springfield dossier. The page does not turn a retrieval gap into a negative fact.
SVC-01 · Evidence-limited
Address-level provider confirmation
The reviewed EPA Version 3 snapshot now shows a PWSID-matched modeled boundary. It is useful geographic context, but it does not prove that a particular Springfield address is connected to the Commission.
Next: Confirm the serving system with the water bill, utility account, Commission, or MassDEP address-specific guidance.
SVC-03 · Evidence-limited
Wholesale and interconnection relationships
The reviewed provider pages describe a regional treatment footprint, but do not establish a named wholesale, consecutive, purchased-water, or interconnection direction for this PWSID.
Next: Review a MassDEP relationship record or provider clarification before naming a counterpart system.
HARD-01 · Evidence-limited
Water hardness
No accepted system-scoped hardness value, period, unit, or basis was found in the reviewed 2025 report extraction.
Next: Search the provider archive and state records for an exact PWSID-bound hardness observation; do not infer hardness from source type.
REG-01 REG-02 REG-04 · Evidence-limited
Violation, enforcement, and sanitary-survey history
The dated July 2, 2026 HAA5 notice and the report’s historical notice language are displayed separately. A structured state/EPA violation history, return-to-compliance record, and sanitary-survey finding set have not been reconciled for this page.
Next: Retrieve exact-PWSID MassDEP and EPA records, retain period/status/source fields, and keep current notices separate.
LSL-01 LSL-02 · Evidence-limited
Lead service-line inventory and replacement
The provider’s lead page gives program context, but this campaign has not accepted a dated PWSID-scoped inventory count or replacement-program schedule. No property-level material is inferred.
Next: Verify the utility or state inventory snapshot, categories, submission date, and customer-side verification path.
TRT-03 TRT-04 · Evidence-limited
Corrosion control and fluoridation
The report contains lead/copper and treatment context, but current corrosion-control configuration and fluoridation status are not established by the reviewed sources.
Next: Use current utility or MassDEP records before publishing a treatment-status claim.
MON-02 MON-03 · Evidence-limited
PFAS, UCMR, and facility testing
No PWSID-bound PFAS/UCMR result set or released school, childcare, or public-building testing result was reconciled here. The lead page is a destination, not proof of participation or results.
Next: Check EPA/state monitoring records and facility-specific releases, preserving sample period, location, units, and scope.
INF-03 OPS-01 OPS-02 OPS-03 · Evidence-limited
Operations, restrictions, outages, and construction
The provider notice and alert destinations are useful official paths, but no current system-scoped seasonal change, drought stage, outage feed, flushing schedule, or construction notice is asserted here.
Next: Recheck the provider’s dated notices and operations pages before adding a current-status statement.
CUS-01 GOV-02 ACC-01 · Evidence-limited
Testing, participation, and accessible formats
Contact, rates, assistance, and report links are available. A customer testing program, public-participation destination, and accessible or translated report format were not fully verified for this system.
Next: Confirm the official contact path and format availability with the provider; keep any request unsent until owner approval.
See the linked internal dossier and status reference for retrieval attempts, owners, and unsent request drafts. No outreach or publication action is taken by this page.
Important limitation
Profile summary note
This page summarizes public records reviewed by this site. It does not replace official notices, utility updates, or state drinking water information.
System profile limitations
- These annual-report values describe the 2025 reporting period, not current conditions at a particular tap. The provider's July 2, 2026 notice reports June 2, 2026 HAA5 sample results at eight locations and shows six of eight Quarter 2 2026 12-month locational running annual averages above the 60 ppb MCL. Follow the dated provider notice for its official instructions, then check the provider's public-notice index for newer notices.
- The Commission reports retail service in Springfield and Ludlow and regional treatment service for several neighboring communities. The Springfield relationship supports navigation but does not prove the provider for every address or imply that Springfield is the system's exclusive service area.
- This page does not determine whether water at a specific tap is safe. Confirm service and current instructions with a bill, the Commission, MassDEP, and the linked public notices.
- Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
- The complete reviewed 2025 report and the historical 2016–2024 English archive are rendered in the Springfield report sections below. These report-period records retain their source scope and do not describe current household-tap conditions.
- Missing fields are not findings. They mean the field is not shown on this page from the records currently available.
- This page summarizes available public records. It may not include every update, notice, or urgent official advisory.
