Tunnell Subsurface Consulting helps contractors, property owners, and legal or insurance teams understand groundwater and subsurface conditions at every stage of a project. We inspect site conditions, respond to problems in the field, provide practical plans of action, and deliver field-informed analysis, clear documentation, and defensible recommendations when conditions need to be understood and managed with confidence.
TSC also helps clients better understand PFAS and how it may affect property, groundwater, project decisions, and long-term risk. That includes educating teams on PFAS concerns, investigating PFAS issues on site, and helping clients approach those issues with practical groundwater and subsurface insight rather than confusion or assumption.
Who We Help
Focused support across construction, property, and technical decision-making.
We help contractors evaluate groundwater and subsurface conditions affecting excavation, dewatering, stability, and site performance. TSC provides practical field analysis, clear documentation, and defensible recommendations when conditions, specifications, or project demands require more than a guess.
Water showing up where it shouldn’t? We help homeowners identify the source of drainage and groundwater issues and provide clear, site-specific solutions—based on actual site conditions, not guesswork.
We provide technical analysis and site evaluation for matters involving groundwater, contamination, drainage, and subsurface conditions—supporting attorneys, insurers, and project stakeholders with clear, well-documented, and defensible conclusions.
Tunnell Subsurface Consulting provides PFAS-related field support and client education for projects where contamination concerns, site history, groundwater conditions, or drainage pathways need to be better understood. We assist with on-site investigation, field observation, pathway evaluation, and practical review of how PFAS may interact with subsurface conditions and water movement. We also help clients understand the broader PFAS issue by explaining sources, transport, exposure concerns, and site-specific risk in clear terms that support better decisions for development, property management, environmental review, and legal matters.
TSC is built on straightforward analysis, clear communication, and integrity in how conclusions are reached and presented. We evaluate site conditions as they exist—grounded in field observation, technical understanding, and practical experience.
Our role is to provide accurate, well-supported information and defensible conclusions. From there, clients can make informed decisions, take action, or determine the appropriate path forward based on the facts.
