Independent Geoscience & Engineering. Clear Environmental Insight.
Document-based hydrogeologic and environmental peer-review built on integrity, clarity, and technical rigor.
Mission Statement
AA GeoEnvironmental offers independent, document-based, third-party peer reviews and analytical evaluations in the fields of geology, hydrogeology, geochemistry, geophysics, statistics, and environmental science & engineering. 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.
