A significant service provided by some companies is to treat groundwater that has dissolved chemicals, fuel oil, or other contaminants. The goal of groundwater remediation or return the groundwater to an uncontaminated state, so these companies build treatment facilities near the contaminated site. The nature and scope of the groundwater remediation facilities depend on the types of contaminants and their concentration.
To treat the water, the remediation companies also drill extraction wells to pump the water from underground to the treatment facility. They may transfer the water to a holding tank to await remediation or send it directly into the treatment process. The treatment process can take many forms, including activated carbon or air stripping, with the treatment process designed around the nature of the contamination. The water may undergo a single treatment state or multiple treatment stages depending on whether there is a single contaminant or multiple contaminants.
Treating the water sometimes requires the water to pass through the system once, or the water may need multiple cycles to treat highly contaminated water properly. Since these remediation facilities are custom-designed to treat specific contamination sources, the remediation companies engineer them to address specific local problems. They build each facility to efficiently remove the local contaminants to a target level, so they optimize the design to achieve that purpose.
