Custom Remediation Design
Tailored remediation solutions engineered specifically for your site's unique environmental challenges, contaminant profiles, and regulatory requirements.
Our Approach
Every contaminated site presents unique challenges requiring specialized solutions. IET's custom remediation design service combines decades of field experience with cutting-edge technology to develop site-specific treatment strategies that maximize effectiveness while minimizing costs.
Our multidisciplinary team evaluates site geology, hydrogeology, contaminant distribution, and regulatory constraints to design remediation programs that achieve cleanup goals efficiently and economically.
Specialized Treatment Areas
Heavy Metal Remediation
Specialized approaches for immobilizing and treating metal contamination:
- In Situ Stabilization: Chemical amendments to immobilize metals and prevent migration
- Chromium Reduction: Converting hexavalent chromium (Cr-VI) to non-toxic Cr-III
- pH Adjustment: Controlling metal solubility through geochemical modification
- Permeable Reactive Barriers: Passive treatment systems for long-term control
Mixed Contamination
Integrated strategies for sites with multiple contaminant classes:
- Sequential Treatment: Phased remediation addressing different contaminant groups
- Combined Technologies: ISCO + bioremediation for optimal results
- Source Zone Treatment: High-concentration areas requiring aggressive approach
- Plume Management: Downgradient treatment for dissolved contamination
Emerging Contaminants
Innovative solutions for newly identified environmental threats:
- PFAS Treatment: Developing strategies for per- and polyfluoroalkyl substances
- 1,4-Dioxane: Advanced oxidation and bioremediation approaches
- Perchlorate: Biological and chemical reduction technologies
- Research Partnerships: Collaboration with universities and technology providers
Complex Site Conditions
Engineered solutions for challenging geological settings:
- Low Permeability: Fracture-enhanced injection for tight formations
- Bedrock Contamination: Strategic well placement and treatment design
- DNAPL Sites: Dense non-aqueous phase liquid source zone treatment
- Urban Settings: Working around utilities and infrastructure constraints
Laboratory & Bench-Scale Treatability Testing
Before committing to full-scale implementation, IET conducts bench-scale treatability studies to confirm technology effectiveness, optimize reagent dosing, and reduce project risk. Treatability testing is a critical step in the remediation planning process — especially for complex or high-concentration sites.
Soil Oxidant Demand (SOD)
Quantifies the mass of oxidant consumed by soil matrix before reaching the target contaminant — essential for accurate ISCO design.
Microcosm Studies
Lab-scale bioremediation tests using site soil and groundwater to confirm microbial populations can achieve reductive dechlorination.
Reagent Compatibility
Assesses how specific amendments interact with site-specific geology, pH, and geochemistry to ensure efficient delivery and longevity.
NAPL Partitioning Tests
Determines how much free-phase product is present and how reagents (e.g., EZVI, surfactants) will partition into the NAPL phase.
