Description
Return treatment-cell water balance and residual.
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 treatment-cell water balance and residual.
When to use this tool
Use Treatment Cell Water Balance Residual when checking the stated remediation measurement, mass/volume balance or support convention.
How to use the tool and how it works
- Enter startingVolume, inflow, outflow, measuredFinal, suppliedLoss. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expectedFinal, residual. Use the output convention below.
Return treatment-cell water balance and residual. Require nonnegative supplied volumes and outflow+loss <= start+inflow; expectedFinal = start+inflow-outflow-loss, residual = measured-expected.1

}Limitations and assumptions
- Use a common period and volume basis; actual flows, storage changes, losses and remediation effectiveness are not verified.
- 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.
