Population served and service connections come from the reviewed EPA Version 3 boundary record for OK2000910, whose source record date is July 26, 2012. These are mapped system-inventory fields, not current address-level service proof.

Read these as system-level fields from reviewed public records. Confirm provider and address-specific questions with official utility, city, state, or EPA sources.

Report-Listed Rows

Report-listed rows summarized from the latest reviewed report

24 report-listed rows are summarized for YUKON. A listed row is not the same thing as a current advisory or household tap result.

How to read these results: a Yukon example

Start with the table’s system name, then read the date, result, units, and benchmark together. The barium row on page 2 belongs to Yukon; Oklahoma City’s purchased-water results appear separately on page 3.

Reported value and units

Barium: 0.282 ppm, labeled “Highest Value.” The report defines ppm as milligrams per liter (mg/L). This is a reported highest value, not a household measurement or an annual average.

Sample date versus report year

The row lists 1/11/2024, even though the report covers 2025 and its title says 2026. The report explains that some contaminants are monitored less often than annually. Keep the printed sampling date when comparing this value with another year.

The benchmark printed beside the result

The row lists an MCL of 2 ppm. MCL means maximum contaminant level—the report’s regulatory limit. The printed result is numerically below that benchmark; this comparison alone does not establish current system compliance or whether water at a particular tap is safe.

The full table also includes averages, lead-and-copper monitoring statistics, and supplier results. Read each row’s own labels rather than treating every number as the same kind of measurement. A blank field is missing information, not zero; a non-detect notation is not a measured zero either.

Source: Yukon’s report covering 2025, page 1 for dates and definitions, page 2 for this example, and page 3 for Oklahoma City supplier results. For current instructions, use the notice and utility contacts.

Boundary source: EPA Version 3; source-record date July 26, 2012; 82.05 km². This preview uses a preserved snapshot, not live coverage. Base-map tiles © OpenStreetMap contributors. Open the official EPA map.

This polygon is an approximate orientation aid, not proof that the utility serves a particular address or every property inside the boundary. The population and connection fields are source-record inventory values, not current household or tap-level evidence. Confirm the provider with a water bill, utility account, or the utility.

Look up mapped systems near your address

EPA’s national map can search by address, water-system name or PWSID. Use it to identify a possible provider, then confirm service with your water bill, utility account or the utility.

Start with an address

Open the EPA map below. In the search dropdown, leave only ArcGIS World Geocoding Service selected. Enter your address and choose the matching location result.

The other search choices look for system names or IDs and can filter out boundaries during an address search.

Check the mapped provider

Select the shaded service area around the result to open its system name, PWSID and source details. For this provider, compare YUKON and OK2000910.

A mapped match does not confirm a connection at your property. Private wells and some public systems are not shown; an empty result does not establish that no provider serves the address.

Open EPA address-search mapReview Yukon customer resources

Lookup checked . EPA describes this map as a first step: boundaries can contain errors, and local government is usually the best source for confirming service to a property. Read EPA’s coverage and limitations. This check does not refresh the preserved map snapshot above.

Violation Records

Violation records shown on this page

This section shows 0 system-scoped violation detail records currently included for YUKON. Annual reports and current notices can use different timing and terminology.

No system-scoped violation detail records are included in the available reviewed records for this system. This is not an official compliance finding. Check the official utility, state, or EPA source for current compliance and notice information.

Source notes for this system mention violation-related context, but this page does not currently display separate system-scoped violation detail records.

PUBLIC WATER SYSTEM

Does Yukon supply your address?

Match the name on your water bill with YUKON, public water system ID OK2000910.

YUKON is listed as an active community water system. Its public water system identification number, OK2000910, helps you match the utility to the right reports even when a document uses a different title.

Start with your bill or utility account. If the provider is unclear, ask Water Management to confirm service for your address. The map is an orientation aid: its underlying record dates to 2012, and its population and connection counts are inventory figures, not current totals.

SOURCE WATER

Groundwater and Oklahoma City purchased water

Yukon uses groundwater wells and water purchased from Oklahoma City. That is why the annual report includes results for two systems.

The April 2026 Water Supply Plan describes the service area south of the North Canadian River, 15 wells drawing from the Garber-Wellington aquifer, and three connections that bring in Oklahoma City water.

When reading the report, check the system named above each table. Yukon results and Oklahoma City supplier results describe different sampling scopes; do not average them together to estimate water at your tap. The plan discusses blending in connection with arsenic, but does not establish the mixture reaching a particular home today.

SYSTEM INFRASTRUCTURE

How water moves through the system

The April 2026 plan describes the network carrying water through Yukon.

The 2026 plan describes more than 130 miles of water lines, typical line sizes of 6 to 18 inches, and a 24-inch transmission line.

These pipe sizes and network totals describe the utility as a whole. They do not identify your property’s service-line material, connection size, or water pressure. For a property-specific question, have your service address ready when contacting Water Management.

ANNUAL REPORT ARCHIVE

Available Yukon report years

Browse results by the year they cover, rather than the year printed in the document title.

The document titled “Consumer Confidence Report – 2026” covers calendar year 2025. This page groups it under 2025. Its 24 results include 13 Yukon rows and 11 Oklahoma City supplier rows; the 2021 and 2022 reports are available separately.

Before comparing years, match the supplier, contaminant, units, sampling date, and statistic. A highest value, average, and 90th percentile describe different things. With 2023 and 2024 reports still missing from the reviewed archive, these records do not establish an uninterrupted year-by-year trend.

DATED REGULATORY CONTEXT

Historical arsenic record

The older arsenic record concerns 2012–2013. Keep those events separate from later annual-report results and current notices.

The reviewed state record shows arsenic MCL-average entries for Q3 2012, Q4 2012, and Q1 2013. The latest listed value is 0.013 MG/L, with status V, a compliance-achieved date of 10-09-2013, and public notification received on 06-07-2013.

“Compliance achieved” is a dated field in this historical record, not a statement about compliance today. The printed status code is retained without assigning it a new meaning. For current instructions, use the city’s Alert Center or contact Water Management.

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

  • The reviewed 2025 report is rendered as 24 reported rows, including separately scoped purchased-water records. The 2021 and 2022 report rows are shown in the historical sections.
  • The ARSENIC row prints 5.9 ppb with range 1.7 - 5.9 and MCL 10. Its MCLG cell is blank and remains absent. The report's arsenic notice says EPA continues to research the health effects of low levels of arsenic and describes arsenic at high concentrations as known to cause cancer in humans and linked to skin damage and circulatory problems. That attributed general information is not a current exposure, individual-risk, medical, household-tap, or safety conclusion.
  • The TTHM row prints Highest RAA 66 ppb and range 26 - 48 ppb. The source-printed statistic and range remain separate without normalization.
  • The report separately prints calendar-year-2025 no-violation statements for YUKON and purchased Oklahoma City water. Their scopes remain distinct and are not assigned to either selected row or presented as current status.
  • Dated state records list three arsenic MCL-average periods from 2012-2013. Status V and the 2013 compliance-achieved field remain together without implying a current arsenic violation, present compliance, exposure, or safety.
  • The Alert Center visibly said there were no active alerts at review. That mutable snapshot is not a durable no-advisory claim.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • This page shows summarized entries from the available report. It does not include a complete contaminant or violation table.
  • 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.
