Groundwater Contamination Assessment & Remediation Strategy
Model groundwater contaminants and develop regulatory-compliant remediation strategies
What You Can Do
You can analyze site contamination data and model contaminant fate and transport to predict plume migration. You'll generate quantified risk assessments that demonstrate regulatory compliance, then design and cost-justify remediation strategies tailored to your site's hydrogeology and regulatory requirements.
Features
Profile contaminant type, concentration, depth, and mobility classification based on soil properties and hydrogeological conditions.
Predict contaminant plume migration using aquifer parameters (porosity, gradient, hydraulic conductivity) and attenuation rates, with spatial extent forecasts over time.
Calculate Health Risk Indices (HHI), hazard quotients, and carcinogenic/non-carcinogenic risk for identified exposure pathways.
Align your assessment to EPA Maximum Contaminant Levels (MCLs), state drinking water standards, risk-based corrective action (RBCA) frameworks, and local ordinances.
Compare technology options (pump & treat, in-situ oxidation, soil vapor extraction, containment, natural attenuation) with effectiveness, timeline, and implementation feasibility.
Estimate capital and operating costs, timeframe-to-compliance, and long-term monitoring requirements for each remediation approach.
Generate defensible reports suitable for regulatory agency submission, including data tables, risk calculations, and remediation justification.
Quantify confidence in predictions by testing how changes in hydrogeological parameters affect plume extent and risk outcomes.
Example Output
Example 1: Risk Assessment Summary
Site: Industrial facility, TCE contamination
Current HHI: 2.3 (exceeds EPA threshold of 1.0)
Primary pathway: Groundwater → municipal well (500 m downgradient)
Compliance gap: Current 85 µg/L TCE; MCL = 5 µg/L
Recommendation: Pump & treat system (12-year timeline, $2.1M capital) achieves compliance by 2038.
Example 2: Plume Prediction (5-Year Forecast)
Year 0: Plume center 50 m downgradient, 150 m wide
Year 5: Plume center 120 m downgradient, 240 m wide
Year 10: Plume center 210 m downgradient, 380 m wide
90% Confidence: ±40 m center position due to aquifer heterogeneity
Example 3: Remediation Comparison
| Technology | Capital Cost | Timeline | Residual Risk | Regulatory Barrier |
|---|---|---|---|---|
| Pump & Treat | $2.1M | 12 years | Low | None |
| In-Situ Oxidation | $1.8M | 8 years | Medium | Requires pilot test |
| Containment | $400K | 2 years | High | Requires deed notice |
| Natural Attenuation | $0 | 25+ years | Very High | Data-intensive monitoring |
