Hydrogeology & Groundwater Investigations
Understand What Is Happening Below the Surface
Groundwater conditions can influence permitting, facility design, compliance, expansion planning, and corrective action. ARM Group develops focused hydrogeologic investigations that turn complex subsurface data into clear, defensible decisions.
Practical Answers for Complex Subsurface Conditions
Every site presents a different combination of geology, groundwater flow, water quality, and regulatory requirements. A successful investigation does more than collect data—it identifies the questions that matter, gathers the right evidence, and builds a reliable understanding of site conditions.
ARM Group supports solid waste owners and operators from initial desktop review and field investigation through conceptual site model development, regulatory coordination, and long-term strategy. Our hydrogeologists, geologists, engineers, and environmental professionals work together to connect subsurface findings with practical facility decisions.

Why ARM Group
Integrated Expertise
Our hydrogeologists work alongside solid waste engineers, environmental scientists, permitting specialists, and construction professionals, connecting subsurface findings to the broader needs of the facility.
Focused Investigation Strategies
We scale the investigation to the site, the regulatory framework, and the decision—combining established field methods with advanced tools when conditions call for them.
Clear, Defensible Interpretation
We organize complex information into understandable conclusions supported by multiple lines of evidence, with attention to uncertainty and data quality.
Practical Regulatory Support
Our teams understand how hydrogeologic findings affect permits, monitoring obligations, design decisions, and agency discussions. We help clients move from technical results to an actionable path forward.
