Description
Compare inlet and outlet contaminant amounts.
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 inlet and outlet contaminant amounts.
When to use this tool
Use Remediation Contaminant Inlet Outlet Mass Term when checking the stated remediation measurement, mass/volume balance or support convention.
How to use the tool and how it works
- Enter inletVolume, outletVolume, inletConcentration, outletConcentration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inletMass, outletMass, difference. Use the output convention below.
Compare inlet and outlet contaminant amounts. Require nonnegative volumes/concentrations; inletMass = inletVolume*inletConcentration, outletMass = outletVolume*outletConcentration, difference = inlet-outlet.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| inletVolume | Inlet Volume | Required. Finite number; minimum 0. |
| outletVolume | Outlet Volume | Required. Finite number; minimum 0. |
| inletConcentration | Inlet Concentration | Required. Finite number; minimum 0. |
| outletConcentration | Outlet Concentration | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| inletMass | Inlet Mass | Required. Finite number. |
| outletMass | Outlet Mass | Required. Finite number. |
| difference | Inlet mass minus outlet mass; storage, other transport and measurement effects are not resolved. | Required. Finite number. |

}Limitations and assumptions
- Volume must cancel the concentration denominator; a difference is not proof of degradation because storage, sampling and unmeasured flows may matter.
- 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.
