Independent Geoscience & Engineering. Clear Subsurface Insights.

Document-based hydrogeologic & environmental peer-review built on integrity, clarity, and technical rigor.

Environmental Technical Review

AA GeoEnvironmental provides independent environmental technical reviews of groundwater models, PFAS fate and transport models, subsurface investigations, hydrogeologic evaluations, and geohazard assessments. The firm excels at transforming complex data into reliable science, assisting clients in making informed and responsible decisions.

Unbiased Scientific Judgment

Our desktop-based peer reviews are based solely on science & Engineering, evaluation of scientific methodological approaches, conflict-of-interest free analysis without regulatory advocacy- dedicated to your interests.

High-Level Analytical Review

Get direct access to an advanced analytical precision of the complex environmental systems. Bridging scientific data and real world perspective. Uncompromised review—just analytical rigor at every scale.

Proactive Risk Management

Foresight informed by scientific and engineering principles for the conscientious environmental stewardship. Identifying challenges and enabling clients to arrive at informed and sustainable decisions.

Our Specialized services

Geology & Hydrogeology

Comprehensive review and interpretation of conceptual site model (CSM), subsurface geology, groundwater, geophysical, geochemical, and geostatistical/statistical data.

Vadose zone & Groundwater Modeling

Review of mathematical and numerical techniques for simulating the behavior of environmental systems, water flow, and contaminants, including a structured approach to data collection and validation.

Indoor air & vapor intrusion Modeling

Exposure pathway reviews of volatile chemicals/soil gas migration from vadose zone into the indoor air of the overlying buildings. Proper sampling procedures to avoid false negatives/positives.

PFAS Investigation & Modeling Review

Unlike many legacy contaminants, PFAS exhibit compound-specific mobility, rate-limited desorption, and multi-phase interactions that complicate investigation and modeling prediction.
