Subsurface Investigations

Trinity is well-versed in performing soil and groundwater investigations, which identify the type, extent, and severity of contamination at a specific property due to chemical leaks, spills, discharges and other environmental releases. These investigations involve collecting data from contaminated properties to assess risks to human health and the environment due to air, soil and water quality impacts.

Groundwater sampling and assessments involve the systematic collection and analysis of water from underground sources to evaluate its quality, pollutants, contamination levels, and suitability for specific land uses. Trinity specializes in sampling strategies, groundwater well installations, and advanced techniques to ensure accurate data collection and compliance with environmental regulations.

Per- and polyfluoroalkyl substances (PFAS) investigations focus on identifying sources of contamination at industrial sites and drinking water systems. Trinity is experienced in developing investigative strategies to accurately identify PFAS impacts from industrial processes, historical operations and environmental releases.

Vapor intrusion sampling methods are essential tools for detecting and assessing the movement of harmful vapors from contaminated soil or groundwater into buildings. By leveraging advanced techniques such as sub-slab soil gas sampling, indoor air monitoring, and ambient air analysis, Trinity can pinpoint contamination sources, evaluate exposure risks, and guide effective mitigation strategies.

Ground Penetrating Radar (GPR) is a non-invasive solution for accurately mapping subsurface features across a wide range of industrial properties. By emitting high-frequency electromagnetic pulses into the ground and analyzing the reflected signals, GPR provides detailed, real-time images of buried utilities, structural elements, voids, and other subsurface anomalies without disturbing the surface.

Groundwater modeling is an essential tool in water resources management, subsurface investigations and site cleanup projects. Through mathematical and computational representations of underground aquifers, our experts can accurately simulate groundwater flow, transport, and contaminant behavior under diverse subsurface conditions.
