environmental investigation and characterization

Our core expertise is investigating, evaluating, and remediating impacts to soil, sediment, groundwater, surface water, and air. Our field investigations accurately define the vertical and lateral extent of chemically impacted media to allow focused evaluation of remediation options and costs. We adhere to exacting quality assurance/quality control procedures to obtain results that support risk analysis, regulatory negotiation, engineering design, and our clients' environmental decisions. Northgate's knowledge of subsurface chemical fate and transport processes is routinely used to develop site-specific cleanup goals and design cost-effective remediation programs.
