Groundwater Services

AquAeTer’s professional hydrogeologists and engineers offer consulting services related to the characterization, monitoring, modeling, and remediation of groundwater systems.

Whether our clients are trying to address issues of water supply or determining if an impact attributable to an industry activity exists, AquAeTer can help develop the most appropriate long-term monitoring system. Our groundwater experts have the ability to characterize and understand groundwater occurrence and movement. This experience includes work in a variety of hydrogeologic settings, including alluvial aquifer systems, flat-lying to intensely folded to karstic sedimentary aquifers, and complexly fractured metamorphic and igneous groundwater-bearing systems in climatic regions ranging from tropical to desert and alpine to arctic. We understand the relationships between groundwater chemistry, geology, and contamination by inorganic or organic compounds as a result of human activity. AquAeTer provides the most effective solutions to groundwater challenges.

Case Studies

Biostimulation

AquAeTer was retained by this client to design, implement, and monitor an in-situ aerobic biostimulation technique for the bioremediation of polycyclic aromatic hydrocarbons (PAHs) for a remote, unconfined, shallow groundwater location. First, a passive, gravity-fed inoculation system was designed to continuously apply AquAeTer’s patented bio-stimulant though a series of injection wells. Additional wells were installed […]

Characterization

AquAeTer was retained by its client to thoroughly review and update the hydrogeologic characterization and ground-water monitoring system for permitting a major landfill expansion on the Colorado Front Range. We revised the characterization of the groundwater regime for this Greenfield site, and that revision became instrumental in obtaining State of Colorado concurrence with an ‘alternative […]

Corrective Action

AquAeTer was asked to assist a client at a wood treating facility that formally used Chromated Copper Arsenate as a wood preservative. Elevated concentrations of arsenic had been detected in downgradiant monitoring wells from the process area. To begin, AquAeTer conducted soil and groundwater sampling to determine potential source areas for elevated arsenic. Geochemical analyses […]

Groundwater Sampling

AquAeTer was retained by its client, an Alaska Native Corporation, to conduct groundwater sampling at sites of historic groundwater contamination at this active US Army base in interior Alaska, south of Fairbanks. Monitored sites included former landfill, fuel tank, and pipeline spill locations where groundwater impacts to deep glacial drift groundwater beneath permafrost were known […]

Groundwater Sampling

AquAeTer was retained by its client, an Alaska Native Corporation, to conduct environmental media sampling over a four-year period at several groundwater contamination sites on the former US Navy air station on remote Adak Island in the Aleutian islands chain of Alaska. The assignment included sampling planning, sampling team management, and sampling oversight. AquAeTer also […]
