eng.pump-treat-cleanup-time Calculator
Calculates pump-and-treat remediation time to achieve cleanup standards from aquifer properties and pumping rate. Pump-and-treat systems are slow — high retardation factors (Kd × ρb / n) mean contaminants desorb from soil much slower than clean water flushes through.
Inputs
Plume Volume M3
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Pumping Rate M3 Day
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Porosity
Reference formula or conversion factor shown for context.
Retardation Factor
A multiplier applied in the calculation.
Results
estimated cleanup time (years)
The computed duration or time value.
pore volumes to flush
The computed three-dimensional volume.
total pore volume (m³)
The computed three-dimensional volume.
pore flushes per year
Reference formula or conversion factor shown for context.
