Three Oregon supplies, with reviewed 2025 report context
The existing Ashland, Grants Pass and McMinnville profiles include report overviews reviewed August 8, 2026. Their reporting years and sample dates remain separate from this guide's September review.
Ashland · OR4100047
Ashland Creek and Reeder Reservoir
Ashland's report for reporting year 2025 identifies Ashland Creek, collected in Reeder Reservoir, as its primary source. Use the report's own source labels and sample dates when reading its tables.
The report says paper copies are available on request. Its source description concerns Ashland Water Department, not every water system with Ashland in its name.
Grants Pass · OR4100342
A Rogue River supply
The Grants Pass 2025 report describes the Rogue River as its drinking-water source and explains treatment, storage and distribution. Those stages help place source-water descriptions and distribution-system results in context.
Keep each result's sampling date, units and result type attached. A report's supply description does not establish current conditions at an individual tap.
McMinnville · OR4100497
McGuire and Haskins reservoirs
McMinnville Water & Light's 2025 report describes precipitation stored in McGuire and Haskins reservoirs, treatment at the Norman Scott Water Treatment Plant, and storage before distribution.
That description belongs to McMinnville's system. It does not identify the provider or water source for a nearby property without confirmation.

Oregon oversight
Public systems and domestic wells use different paths
Oregon Health Authority's Drinking Water Services provides public-system records and program guidance. Its online search identifies the regulating agency for each listed system.
The Domestic Well Safety Program provides a separate path for household well owners. A nearby public-system report cannot establish the condition of a private well.
Record freshness
Live records still depend on reporting
Oregon's Data Online introduction says most displayed information reflects reports already in its system. A missing item can mean it has not been reported or entered yet.
Check the sample date, record category and update context. A blank field or missing report does not mean a contaminant was absent, and a historical result does not establish today's advisory status.
System identity
One place name can match several providers
An Oregon name search for Ashland returns separate systems, including Ashland Water Department and smaller systems with Ashland in their names. Match the system identifier as well as the name.
Use your water bill or ask your landlord or property manager to identify the provider, then confirm service with that provider. The site coverage listed here is not Oregon's statewide inventory or an address-service map.

Data Online
Search the name, then keep the exact number
Oregon's Water System Search accepts a system name or number. The name can return several matches, while the state's five-digit system number can narrow the result.
The search also offers a location map. A mapped system point is not proof that the provider serves an address.
- Open Water System Search and enter the provider's name in the search field.
- Select Search, then compare Water System Name, PWS ID and Regulating Agency in the returned rows.
- Open the matching system row and use its inventory and linked record categories for the question you need to answer.
- Ask the provider to confirm service to your address before applying a report or notice.
Verified example
Ashland's state record is 00047
A September 13 search for 00047 returned ASHLAND WATER DEPARTMENT and opened its Oregon inventory record. EPA's official data identifies the same system as OR4100047; Ashland's report prints 4100047.
These are different presentations of the verified system identifier. Use 00047 for this Oregon lookup example and keep the full OR4100047 PWSID when comparing the existing site profile or EPA record.
Official tools

Advisories and notices
Check status, affected area and instructions
Oregon's Water Advisories tool distinguishes advisories In effect from Lifted, system-wide from partial areas, and all populations from vulnerable populations. Check those fields and the notice details before applying an instruction.
The tool says advisory tracking began in May 2017 and most earlier advisories are not displayed. An empty result is not confirmation that no current provider instruction applies. Ask your provider which local notification options cover your address.
Service-line records
A blank inventory cell is missing information
Oregon's Service Line Inventories page covers active community and non-transient non-community systems required to submit inventories. Its instructions say a blank cell means OHA does not have inventory data for that system and line type.
Use the system row for its lead-and-copper page, then ask the provider about the material record for your property. Inventory classifications describe pipes; they are not tap-water lead test results.
PFAS samples
Keep the facility and sampling date with the result
Oregon's PFAS Sample Results page separates sample summaries and sample data. Its instructions explain searching the table and opening a system row to see that system's results.
Check the facility, named compound, sample date, units and reporting limit. Filters and hidden columns affect the view; a missing row or an untested compound is not a zero result.
Domestic wells
Separate routine testing from a property sale
OHA recommends annual private-well testing for coliform and E. coli bacteria and nitrate, with arsenic testing every three to five years. Local conditions or changes to the well can call for additional tests.
Oregon has a separate domestic-well testing and reporting process for real-estate transactions. Use that official guidance for a sale, and contact an accredited laboratory for collection instructions, current test availability and fees.
Reports and assistance
Request the report or record you need
Start with the provider's annual Water Quality Report or Consumer Confidence Report. Ashland's 2025 report offers paper copies on request; ask other providers what formats or languages they can supply.
For questions about Oregon inventory, sampling or compliance records, use Drinking Water Services' contact page. Ask the provider for current local instructions rather than relying on an older annual report.
Common questions
Use Oregon's numbers and records consistently
Why does Ashland show 00047 in the state search?
Oregon's verified inventory record uses 00047, EPA uses OR4100047, and Ashland's report prints 4100047. Match the name and identifier together; use the number format shown by the tool you are using.
Does a blank service-line cell mean there is no lead?
No. Oregon's page says a blank cell means inventory data are missing for that system and line type. Ask the provider about the material record and keep it separate from tap-water testing.
Can I apply any advisory with my city's name?
Match the provider, status, affected area and affected populations first. The tool distinguishes partial from system-wide notices and in-effect from lifted advisories. Follow the current official instructions for your confirmed system.
