Arkansas Water Quality Records

Fayetteville · AR0000569

Purchased water from Beaver Water District

Fayetteville’s 2025 report says the utility purchases treated surface water from Beaver Water District, whose source is Beaver Lake. The wholesale source and Fayetteville’s retail system remain distinct records.

Its TTHM table distinguishes a sample range from the highest running 12-month average. Read those measures with the printed limit, flag, and report context before interpreting the row.

Fort Smith · AR0000507

Two watersheds and a dated tank deficiency

Fort Smith’s 2025 report describes Frog Bayou watershed water stored at Lake Fort Smith and Lee Creek watershed water stored in Lee Creek Reservoir, with treatment at the corresponding plants.

The report also discloses a March 25, 2025 significant deficiency involving tank screening and grading, with “No corrective action taken” printed under Progress to Date. That dated report statement does not establish the deficiency’s present status. Its lead-and-copper table separately reports site exceedances and 90th-percentile results.

Springdale · AR0000575

A separate retail report using the same wholesale source

Springdale’s 2025 report also identifies purchased treated surface water from Beaver Water District and Beaver Lake. Use Springdale’s own system identifier and report when it is your confirmed supplier.

Its TTHM table also separates a sample range from a running 12-month average. A range maximum and the compliance measure are different fields and should stay together with the report’s printed context.

Wholesale and retail

Beaver Lake does not identify your water utility

Fayetteville is AR0000569 and Springdale is AR0000575. Both reports identify Beaver Water District as their treated-water supplier, but the retail systems have separate identities and monitoring. Confirm the provider on your bill instead of choosing a report by lake name.

Report measures

A range and a running average answer different questions

The Fayetteville and Springdale TTHM tables include both a sample range and a highest running 12-month average. Fort Smith’s lead-and-copper table separates the count of sites over an action level from the 90th percentile. Keep these measure labels and their reporting periods attached to the values.

Source protection

Watershed information describes the water source

Arkansas Department of Health’s source-water guidance describes protection work within watersheds and aquifers. It helps explain potential influences on a source. A watershed boundary does not establish a utility’s customer boundary or a household test result.

Shared sources

Can I use Fayetteville’s report for Springdale?

No. The two reports describe the same wholesale supplier, but Fayetteville AR0000569 and Springdale AR0000575 remain separate retail systems. Use the report for your confirmed provider.

Table measures

Can I compare a TTHM range maximum directly with the printed average?

They are different measures. Fayetteville’s and Springdale’s tables report a sample range and a highest running 12-month average. Keep the printed measure, limit, flag, and reporting period together; the range maximum alone is not a new compliance finding.

Private wells

Will the state microbiology test include nitrate or metals?

The laboratory lists total coliform bacteria and E. coli as its water tests. Ask an environmental laboratory about other analyses and their collection instructions before you collect a sample.
