Groundwater

RCC performs groundwater investigations to assess subsurface hydrogeologic conditions, determine the presence and extent of contamination, and support regulatory compliance, remediation planning, and property transactions. Groundwater assessments are typically initiated following Phase I findings, soil impacts, regulatory directives, or as part of ongoing site monitoring programs.

Field activities may include:

  • Installation of temporary or permanent monitoring wells

  • Development and purging of wells using low-flow or traditional methods

  • Measurement of groundwater elevation and hydraulic gradients

  • Groundwater sampling under strict QA/QC protocols

  • Collection of field parameters (pH, DO, turbidity, ORP, etc.)

  • GPS-based data capture for accurate mapping and reporting

Samples are analyzed by certified laboratories for compounds such as petroleum hydrocarbons, chlorinated VOCs, metals, PFAS, pesticides, PCBs, or other site-specific parameters. Analytical results are evaluated to determine:

  • Presence, distribution, and concentration trends of contaminants

  • Migration pathways and potential exposure risk

  • Plume dynamics relative to receptors such as utilities, wetlands, or potable wells

  • Need for additional delineation or remedial response actions

Groundwater investigations support a broad range of project types, including UST releases, industrial site compliance, landfill monitoring, brownfield redevelopment, emerging contaminant studies, and long-term post-remediation monitoring programs.
