Groundwater Management

Develop a clear understanding of groundwater conditions through hydrogeologic investigations, geological mapping, geophysical assessments and conceptual site models. Onterris evaluates aquifer characteristics, groundwater flow pathways and connections with surface water and groundwater-dependent ecosystems. Integrated field investigations, groundwater sampling and geochemical analysis provide a defensible foundation for development planning, permitting and remediation decisions.

Navigate groundwater permitting, licensing and compliance with technical support informed by local regulatory requirements. Onterris helps clients evaluate water availability, plan groundwater withdrawals, assess aquifer vulnerability and develop sustainable resource management strategies. Across the United States, Canada and Australia, specialists apply regional regulatory knowledge to support responsible groundwater use, contaminated land projects and long-term water resource planning.

Reliable groundwater data begins with properly designed monitoring and well systems. Onterris supports groundwater monitoring, supply, dewatering and disposal wells through design, installation, optimization and hydraulic testing. Aquifer pumping tests, groundwater level monitoring and water quality sampling help characterize hydraulic properties, evaluate system performance and guide operational decisions throughout the project lifecycle.

Groundwater modeling helps organizations understand subsurface conditions and predict how groundwater systems may respond to development, pumping, dewatering or environmental change. Onterris develops conceptual, analytical and three-dimensional numerical models to simulate groundwater flow, contaminant transport, surface water interactions and thermal effects. Calibrated against field observations, these models support impact assessment, water balance analysis, remediation planning and defensible regulatory submissions.

Protect drinking water sources and groundwater supplies through aquifer vulnerability assessments, wellhead protection, water quality investigations and long-term supply planning. Onterris evaluates potential threats to groundwater quantity and quality, including changing land use and contaminant migration. Integrated technical studies help clients balance water demand with environmental protection while addressing applicable regulatory requirements.

Groundwater contamination requires a clear understanding of contaminant sources, migration pathways and potential receptors. Onterris supports groundwater investigations, including per- and polyfluoroalkyl substances (PFAS) characterization, sampling and contaminant transport modeling. Integrated consulting, laboratory and treatment capabilities connect assessment findings with remediation planning, treatability testing and treatment system operation.
