Examples of LNAPL in a sentence
The ROD requires that the LNAPL recovery system operate until the remedial action objectives have been achieved or until it is determined that the continued operation of the LNAPL recovery system is technically infeasible or impracticable.
The companion software, API- LNAST, links the multiphase and chemical processes controlling in-situ LNAPL distribution, mobility, and cleanup to quantify estimates of the time-dependent concentrations within the LNAPL source and the down gradient dissolved plume.
This report provides theory and concepts needed to evaluate light nonaqueous phase liquid (LNAPL) source distribution, chemistry, dissolution, and the effects various remediation strategies may have on risk reduction for the groundwater and vapor exposure pathways.
This condition is particularly important where there is evidence of light NAPL (LNAPL) on the water table directly below the building or direct evidence of intrusion of liquid-phase contamination (i.e., liquid chemical or dissolved in water) inside the building.
Periodically, the performance metrics of the LNAPL recovery system will be evaluated to determine if the remedial objectives of the system have been achieved or if the system has reached asymptotic conditions (i.e. its practical limits) for sustainable and effective recovery of LNAPL.
For a more complete description of LNAPL assessment requirements see Assessment Guidance for Sites with Residual Weathered Product, RR-787.
DuChanois, R.M., Liddle, E.S., Fenner, R.A., Jeuland, M., Evans, B., Cumming, O., Zaman, R.U., Mujica- Pereira, A.V., Ross, I., Gribble, M.O., and Brown, J.
During the operation of the LNAPL recovery system, the performance of the system will be evaluated and adjusted to optimize recovery.
API-LNAST users can screen whether incremental LNAPL removal provides any risk-reduction benefit over a time frame of interest, e.g. 30 years.
