Expedited Site Characterization:
Demonstration at Marshalltown, Iowa
Conference Session: "Overview of the Cleanup Process"
Speaker: Dave Wonder
I. The Environmental Remediation Process
- Regulator's Role
- Identify the problem
- Identify the Responsible Party (PRP)
- Address matters of non-compliance
- Regulatee's Role
- Report known problems
- Achieve compliance
- Minimize cost and time
II. Achieving Compliance
- Voluntary and proactive
- Remedial investigation (RI)
- "site assessment"
- "facility investigation"
- "site characterization"
- Risk assessment
- Feasibility study (FS)
- evaluate applicable technologies
- "corrective /remedial action plan"
- Record of Decision (ROD)
- Remediation performed
III. Risk Assessments
- Scientific effort to estimate nature, probability and magnitude of risk
- Contaminant exposure routes
- Contaminant toxicology
- Does not address acceptibility of risk -- risk management
- Examples
IV. Elements of a Site Characterization
- Identify regulated substance
- Determine Handling Processes
- Take measurements
- Geologic/geotechnical
- Hydrologic
- Chemical
- Goals: Where it came from, where it is, where it is likely to go
- "Fate and Transport"
- One eye on remediation
V. What is Clean
- Groundwater Quality Standards
- Maximum contaminant level (MCL)
- Health advistory level (HAL)
- Negligible risk level (NRL)
- Protect human health and the environment
- Soil Standards
- Protect groundwater supplies
