Measure how effectively a leak-response system captures released liquid. Compare detected release volume with recovered liquid, subtract known non-leak additions, and account for reusable recovered material. The calculator reports gross capture, adjusted recovery rate, unrecovered volume, and reusable volume for response reviews and improvement tracking.
Adjusted recovery rate compares attributable recovered liquid with the estimated release. Removing rain or flush water avoids crediting the response for liquid that was not part of the leak.
Both released and recovered volumes carry measurement uncertainty. A result above 100% usually signals inconsistent estimates, timing, inventory, or unaccounted added liquid.
From an estimated 5,000-gallon release, 4,300 gallons are collected, including 300 gallons of rain or flush water. Adjusted recovery is 4,000 gallons, or 80%. The unrecovered volume is 1,000 gallons, and an 80% reusable share yields 3,200 reusable gallons.
Those additions were not part of the original leak and would otherwise overstate recovery performance.
It can mathematically, but it usually indicates measurement mismatch or unaccounted added liquid and should be investigated.
It is the released volume minus adjusted recovered volume, limited to no less than zero.
Enter zero for rain or added flush water.
No. Reusable volume applies the entered reusable share to the adjusted recovered liquid.
| Measure | Formula | Use |
|---|---|---|
| Adjusted recovered | Collected − additions | Attributable capture |
| Recovery rate | Adjusted ÷ released | Response effectiveness |
| Unrecovered | Released − adjusted | Loss estimate |
| Reusable | Adjusted × reusable share | Reuse planning |
