Term Identity
What the term means in an annual report
Uranium in this context is a named radionuclide measured by mass concentration rather than a generic radiation result.
Why it may appear
Systems report uranium monitoring as a distinct federal radionuclide entry for the named sample period.
How it may be printed
Reports may say Uranium or Uranium, Mass Concentration and often use micrograms per liter or ppb with MCL and MCLG fields.
- Other names you may see
- Uranium; Uranium mass concentration
- Common report labels
- Uranium; Uranium, Mass Concentration

Regulatory Context
How to read the applicable rule language
Use this Uranium context to read a report's printed fields; it does not replace the report or the current official rule.
Framework
Uranium has its own federal mass-concentration standard. It is not the same measurement as gross alpha in pCi/L or beta/photon dose in mrem per year.
Limit or program terms
- MCL
- MCLG
- Mass concentration
Units and source context
Reports may use micrograms per liter or ppb. Preserve the exact unit and do not express the uranium standard as pCi/L.
What this page does not duplicate
Use the mass concentration printed in the report and the current official radionuclide rule; do not merge it with other radionuclide rows.
No standalone numeric limit table is rendered here. Read the source report's printed criterion and the current official source together.
Interpretation Boundaries
What a listed result does not establish
These Uranium boundaries apply to every report row connected to this explainer.
Household-level boundary
A system annual-report uranium result does not establish current conditions at a particular tap.

Radionuclides
Combined radium 226 and 228
Combined radium is the sum of radium-226 and radium-228 results for the federal drinking-water standard. It is not a general page for every radionuclide.

Gross alpha particle activity
Gross alpha is an activity measurement for alpha-emitting radioactivity. It does not identify one specific substance and is not equivalent to radium, beta/photon activity, or uranium.

Beta particle and photon radioactivity
Beta particle and photon radioactivity uses a dose-based federal standard. A 50 pCi/L gross-beta screening level is not the federal MCL.
