Real EPA measurements of uranium for Arkansas water systems — Six-Year Review compliance samples 2012–2019 (historical). Methodology
EPA does not publish per-city uranium measurements for Arkansas in the datasets we use, so this section shows what regulators actually recorded: every Safe Drinking Water Act violation tied to uranium at the 18 Arkansas public water systems we track, since 2016. Source: EPA SDWIS via ECHO (2026 Q2 extract).
No uranium violations on record. None of the 18 tracked Arkansas systems has a SDWIS violation for uranium since 2016. That means no monitoring, reporting or limit violation was logged — it is not a lab result for your tap. Check your utility's annual Consumer Confidence Report for measured levels.
Every Arkansas system with a uranium result in EPA's data, sorted by level. Averages of 2012–2019 finished-water samples, non-detects counted as zero — historical, not today's tap.
No uranium detections have been reported in Arkansas cities.
Uranium poses both chemical and radiological health risks. As a heavy metal, uranium is toxic to the kidneys and can cause kidney damage and eventual kidney failure with long-term exposure. As a radioactive element, uranium exposure increases cancer risk, particularly bone cancer due to accumulation in bones. The chemical toxicity to kidneys is the primary concern at levels found in drinking water.
Erosion of natural deposits; common in certain geologic formations, especially granite
Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,uranium has been detected in 0 Arkansas water systems.
The EPA MCL for uranium is 30 micrograms per liter (30 ppb). The EPA MCL for uranium is 30 ug/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
0 Arkansas cities have uranium detected in their water supply. All tested cities are within EPA safety limits.
Kidney damage and potential kidney failure, increased cancer risk. The most vulnerable groups include people with kidney disease and pregnant women.
The most effective methods for removing uranium include Reverse Osmosis, Strong Base Anion Exchange, Distillation. Look for filters certified by NSF/ANSI for uranium reduction.
The EPA Maximum Contaminant Level (MCL) for uranium is 30 ug/L.The EPA MCL for uranium is 30 micrograms per liter (30 ppb).
This page shows what Arkansas utilities reported for uranium. It cannot tell you what is coming out of your own tap: utility samples are taken across a whole system and averaged, levels vary by address and season, and anything picked up after the water leaves the main never appears in their report.
