Insights into Biotechnological Approaches for Treatment of Petroleum Refinery Effluents

Hydraulic control or hydraulic containment is a groundwater containment method by which further migration of pollutants is limited, hence minimizing the permanent extension of the polluted area (Chukwunonso et al. 2020). This method effectively decreases the quantities of the dissolved pollutants in groundwater. This depends on pumping the polluted groundwater up via mining wells, removal of pollutants from the surface, followed by water reinjection or offsite water disposing via transferring to a treatment plant. After containment of pollutants, both type and degree of contamination majorly determine whether physical, chemical or biological treatments should be applied.

Use of pumping systems to control or manipulate the movement of contaminated groundwater in pre-existing plumes. In some circumstances, the pumping is intended to lower the groundwater levels around the contaminated area so that groundwater flow is towards the source, preventing outward migration of contaminants – this approach is sometimes termed hydraulic containment (Figure 17.36a).

The contaminants at a remediation site are usually contained using cutoff walls or hydrodynamic controls. Sheet walls and slurry walls are common cutoff methods used to control groundwater movement. Injection wells and pumping wells are the two most popular methods of hydraulic containment.

With suitable groundwater conditions, phytoremediation can be an affordable, low-maintenance method to achieve hydraulic containment and treatment of soluble contaminants. In particular, for dilute slow-moving plumes in shallow aquifers, phytoextraction is a feasible alternative to decades-long pumping and treating of contaminated groundwater. Although plant selection must take into account local climate, hydrology, and native vegetation, poplar (Populus spp.) species are frequently planted for hydraulic containment because these trees thrive in a variety of climates, remove large amounts of water, quickly grow expansive roots and canopies, and tolerate greater concentrations of volatile organic contaminants (Ferro et al.1999; USEPA 2000; Eberts et al.2003; Ferro et al.2003; Matthews et al.2003; McCutcheon and Schnoor 2003; Voss et al.2003; ITRC 2009).
