Efficient groundwater cleanup starts here.
Proven solutions to remove contamination, protect water quality, and restore environmental balance.
A trusted method for groundwater remediation.
Groundwater contamination can pose serious risks to public health and environmental safety. Pump and Treat (P&T) is one of the most established and reliable methods for addressing these risks. By extracting contaminated water, treating it above ground, and returning clean water to the environment, this method ensures both safety and compliance. Hanis Consulting brings decades of expertise to designing and implementing Pump and Treat systems that deliver sustainable results.
The science of contaminant removal.
Groundwater Pump and Treat technology addresses contamination in the saturated zone by extracting polluted water for above-ground treatment. While the concept is simple, achieving optimal results requires an understanding of site-specific hydrogeology, contamination profiles, and regulatory requirements.
-
Extraction Wells:
- Strategically placed wells are used to pump contaminated water from the subsurface, targeting the plume for maximum efficiency.
- These wells reduce hydraulic pressure and prevent further spreading of contaminants.
-
Above-Ground Treatment:
- Extracted groundwater is treated using a combination of technologies, including air strippers, activated carbon, and chemical oxidation, to remove contaminants.
- Treatment systems are tailored to the specific contaminants present, ensuring regulatory compliance.
-
Reinjection or Disposal:
- Once treated, the clean water is either reinjected into the aquifer, discharged into a surface water body, or sent to a wastewater treatment facility.
- This process ensures the safe reintroduction of water into the environment.
-
Continuous Monitoring:
- Systems are monitored in real-time to evaluate performance and ensure consistent contaminant removal.
- Monitoring data is used to adjust system operations and optimize efficiency over time.
Groundwater Pump and Treat remains a versatile and effective solution for mitigating environmental contamination, offering flexibility to address a variety of pollutants and site conditions.
Is pump and treat right for your site?
Not every site is suited for Pump and Treat remediation. Its effectiveness depends on key factors such as geology, contaminant type, and project timeline. Here’s what makes a site ideal for this method:
- Geology: Works best in high-permeability soils like sands and gravels, where contaminants can be efficiently drawn to extraction wells.
- Land Use: Ideal for urban and industrial sites where contamination has the potential to affect drinking water or surface water.
- Time Constraints: Effective for both short-term projects and long-term remediation goals, although results may require continuous operation over months or years.
- Contaminants: Commonly used to address petroleum hydrocarbons, solvents, and heavy metals in groundwater.
