Dynamic LNAPL Recovery for Hydrocarbon-Impacted Sites

Long-term recovery of free-phase hydrocarbons using Dynaskim® technology to remediate historical fuel contamination caused by leaking storage tanks and service stations. The solution combines automated groundwater pumping and dynamic skimming to maximize hydrocarbon recovery while minimizing operational requirements.

SITE DESCRIPTION

Treated Volume	Hydrocarbon-impacted industrial and commercial sites
Thermal technology	Dynamic LNAPL Skimming
Main contaminant	Heating oil, diesel and petrol
Site challenges	Historical or accidental leaks resulting in free-phase hydrocarbons beneath or around underground storage tanks.
Project Timeline	from 2019

SOLUTION

Treatment Method	Dynamic LNAPL recovery using skimmers
Treatment program	Installation of 8 recovery wells equipped with automated pumping units and skimmers.
Contaminated Vapors Management	Not applicable
Process control	Automated groundwater pumping combined with continuous free-product recovery using DS 500-6D pumping units and SKIM 4-250 skimmers.
