Description
Compare measurement with a supplied target and upper uncertainty.
Environmental-remediation bookkeeping uses explicit water, soil, dry-mass, concentration and sampling bases. A local mass residual, censored-result bound or supplied target margin does not identify a removal mechanism, establish representativeness or determine an environmentally acceptable contaminant level.
Compare measurement with a supplied target and upper uncertainty.
When to use this tool
Use Bioremediation Supplied Target Margin when checking the stated remediation measurement, mass/volume balance or support convention.
How to use the tool and how it works
- Enter measured, target, uncertainty. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nominalMargin, conservativeMargin, definitelyBelow. Inspect definitelyBelow before interpreting the associated values.
Compare measurement with a supplied target and upper uncertainty. Require uncertainty >= 0; nominalMargin = target-measured, conservativeMargin = target-measured-uncertainty, definitelyBelow tests measured+uncertainty <= target.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measured | Measured | Required. Finite number. |
| target | Target | Required. Finite number. |
| uncertainty | Uncertainty | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nominalMargin | Nominal Margin | Required. Finite number. |
| conservativeMargin | Conservative Margin | Required. Finite number. |
| definitelyBelow | measured+uncertainty <= target, including equality, assuming uncertainty is a valid bound; no acceptable target is selected. | Required. Boolean. |

} Limitations and assumptions
- The named below flag includes equality and assumes the supplied half-width is a valid bound; no legal limit, confidence level or safe condition is established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified sampling and analytical data, consistent material/unit bases and a complete transport or treatment model; involve qualified environmental professionals for practical or regulatory decisions.
