Phase 2 Environmental Site Assessments

A Phase 1 Environmental Site Assessment identified potential contamination on your site. Now you need a Phase 2 ESA to determine exactly what you're dealing with, how extensive it is, and what it will take to remediate it.

Terra-Sano conducts Phase 2 Environmental Site Assessments with all field investigation capabilities in-house, including electromagnetic surveying, direct-push sampling, drone documentation, and specialized testing equipment. Same company. Same project manager. When the assessment is complete, and remediation is needed, the same team that identified the contamination fixes it.

Our Phase 2 ESA Services

Desktop Analysis & Investigation Planning

Every Phase 2 assessment starts with thorough planning based on Phase 1 findings, historical site use, and regulatory requirements. Our environmental professionals develop investigation strategies that we can take action on.

Subsoil Salinity Tooling Application

Salt contamination is one of the most common issues on oil and gas sites, particularly from produced water or historic brine spills. Subsoil salinity tooling enables us to help develop Tier 2 site-specific remediation guidelines for chloride and sodium contamination in soil, protecting groundwater and surface water.

Aerial Drone Surveys and Inspections

Our RTK (Real-Time Kinematic) drone services provide high-precision aerial documentation and site mapping as part of Phase 2 assessments. Drone surveys give us a complete picture of site conditions and help identify investigation areas that might be missed from ground-level observation alone.

Electromagnetic (EM) Surveying

EM surveys are one of the most valuable tools for assessing potential soil and groundwater contamination. They detect subsurface anomalies that may indicate buried infrastructure, contaminated soil, or salt-affected areas, guiding where detailed sampling should occur.

Our EM surveying capabilities help us investigate sites more efficiently, reducing unnecessary sampling while ensuring we don't miss contaminated areas.

Direct Push Sampling

Once investigation areas are identified, we need soil and groundwater samples to characterize contamination. Direct push technology allows us to collect samples quickly without the time and expense of conventional drilling. This service decreases the chances of cross-contamination and allows for better sample integrity.

Having direct push capabilities in-house means faster mobilization, better coordination between survey work and sampling, and seamless integration with remediation planning.

We also have traditional auger capabilities to meet any demands.

Comprehensive Reporting

Phase 2 ESA reports document the entire investigation and provide clear conclusions about site conditions. Our reports are designed to meet regulatory requirements while providing you with actionable information about what needs to happen next.

Why We’re Trusted for Phase 2 Assessments

Because We Optimize Investigation Strategies for Cost

Phase 2 assessments can become expensive quickly if investigation strategies aren't well planned. Our integrated approach allows us to:

  • Use EM surveys to target sampling locations precisely, reducing unnecessary soil sampling
  • Conduct field screening to adjust investigation strategies in real-time
  • Mobilize equipment efficiently

Because We've Done This Hundreds of Times Across Alberta

You're benefiting from years of experience conducting Phase 2 assessments across Alberta's diverse site conditions and contamination scenarios. We know what approaches work best for different site types and contamination scenarios and how to interpret field observations and adjust sampling strategies accordingly. We are also knowledgeable about what regulators expect to see in Phase 2 reports.

Phase 2 Assessments Across Alberta

Our project management team and field investigation equipment operate throughout Alberta. Whether your sites requiring Phase 2 assessments are concentrated in one area or scattered across the province, we have the geographic coverage and equipment to execute investigations efficiently.
