Parsons is a strong advocate of risk-driven investigations and risk-based remediation. Risk-driven site investigations identify the most efficient and cost-effective site remedy at the outset to prevent the collection of unnecessary field data. This proactive approach creates a positive negotiating stance with regulatory agencies, setting the tone of the project and minimizing the potential changes later in the project. Parsons risk-based remediation services are based on the requirement to protect human health and the environment by using the best available technology and realistic approach, which includes:

• Preparing quantitative human health risk assessments consistent with the regulations
• Assessing concentrations of chemicals in air, soil, groundwater, surface water, or sediment
• Negotiating site closure and the "no action" alternative based on health considerations due to exposure or potential contamination of adjacent areas
• Identifying the most cost-appropriate, risk-based remedial alternative
• Developing risk-driven sampling plans for hazardous waste sites
