Soil & Groundwater Remediation

Understanding Soil and Groundwater Contamination

Soil and groundwater contamination results from various sources including leaking underground storage tanks, industrial operations, chemical spills, dry cleaning facilities, and improper waste disposal. Contaminants can persist in the subsurface for decades, migrating through soil layers and spreading in groundwater, creating expanding pollution plumes that threaten water supplies and expose people to health risks. Professional remediation is often required to meet regulatory standards and allow beneficial property use.

​

Common contaminants we remediate: Petroleum hydrocarbons (gasoline, diesel, heating oil), chlorinated solvents (PCE, TCE), BTEX compounds, heavy metals, pesticides, and various industrial chemicals.

Comprehensive Remediation Approaches

Effective remediation requires matching cleanup methods to site-specific conditions and contamination characteristics. Our remediation services address both soil and groundwater contamination:

• Excavation and off-site disposal of contaminated soil for rapid source removal

• Soil vapor extraction to remove volatile compounds from unsaturated soil

• Air sparging and biosparging for in-situ groundwater treatment

• In-situ chemical oxidation for rapid breakdown of organic contaminants

• Enhanced bioremediation using microorganisms to degrade contaminants naturally

• Pump-and-treat systems for groundwater extraction and treatment

• Multi-phase extraction for simultaneous soil and groundwater remediation

• Permeable reactive barriers for passive groundwater treatment

• Monitored natural attenuation where site conditions support natural cleanup processes

 

Site Assessment and Remedial Planning

Successful remediation begins with thorough site characterization. We evaluate contamination extent, soil and groundwater conditions, contaminant mobility, exposure pathways, and cleanup objectives to develop effective remedial strategies. Our remedial action plans detail cleanup methods, performance monitoring protocols, contingency measures, and completion criteria. These plans undergo regulatory review and approval before implementation begins.

 

Active Remediation System Management

Active remediation systems require professional operation and maintenance to achieve cleanup goals efficiently. We provide complete system management including equipment installation oversight, startup and optimization, routine inspections, performance monitoring, system adjustments, compliance reporting, and troubleshooting. Our proactive management approach maximizes contaminant removal rates while minimizing operational costs and downtime.

 

Groundwater Monitoring and Long-Term Management

Many remediation projects include groundwater monitoring to track contamination trends and verify cleanup effectiveness. We install and maintain monitoring well networks, conduct regular sampling events, analyze water quality data, evaluate contaminant fate and transport, and prepare monitoring reports for regulatory agencies. Long-term monitoring programs demonstrate that contamination is decreasing and support applications for regulatory closure.

 

Regulatory Coordination and Closure

Remediation projects in New Mexico require coordination with the New Mexico Environment Department and sometimes EPA. We manage all regulatory interactions including remedial plan submittals, progress reports, regulatory meetings, and closure applications. Our familiarity with state cleanup standards and closure processes helps clients navigate regulatory requirements efficiently and achieve final site closure.

 

Cost-Effective Solutions

Remediation represents a significant investment, and we focus on delivering cost-effective solutions that meet cleanup objectives without unnecessary expense. We evaluate technology alternatives considering capital costs, operating costs, timeframes, and reliability. Our practical approach balances cleanup effectiveness with economic reality, helping clients manage remediation budgets while achieving environmental goals.
