Description
Return contaminant mass from a sample-mass concentration.
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.
Return contaminant mass from a sample-mass concentration.
When to use this tool
Use Contaminant Mass Sample Factor when checking the stated remediation measurement, mass/volume balance or support convention.
How to use the tool and how it works
- Enter concentration, sampleMass, unitFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read contaminantMass. Use the output convention below.
Return contaminant mass from a sample-mass concentration. Require concentration/sampleMass >= 0 and unitFactor > 0; contaminantMass = concentration*sampleMass*factor.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| concentration | Concentration | Required. Finite number; minimum 0. |
| sampleMass | Sample Mass | Required. Finite number; minimum 0. |
| unitFactor | Unit Factor | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| contaminantMass | Contaminant Mass | Required. Finite number. |

}Limitations and assumptions
- The factor must reconcile mass-fraction units, such as mg/kg versus kg; analytical accuracy and hazard/compliance are not 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.
