TRAINING.

Overview

After participating in this course, you will be able to:

• Analyze the overall framework of risk assessment and exposure control for contaminated sites.
• Apply risk assessment guidelines and tools to evaluate environmental and health risks.
• Develop site-specific risk-based guidelines and implement risk management strategies.
• Conduct contaminant fate and transport modelling for exposure evaluation.
• Formulate effective risk management plans based on risk assessment outcomes.

Description
Environmental contamination poses significant challenges when contaminants in soil and groundwater exceed regulatory guidelines. Addressing these issues requires a comprehensive understanding of risk assessment and management. This course delves into the legal framework and methodologies for conducting environmental site assessments, focusing on human health and ecological risks. You will explore the various aspects of risk assessment, including toxicity, carcinogenicity, and the development of conceptual site models.

Participants will learn about the critical steps in risk assessment, from problem formulation to exposure evaluation, using simplified modelling tools for contaminant fate and transport. By understanding the dose-response relationships for contaminants, you will be equipped to determine the necessity for remediation or alternative risk management strategies. The course also covers risk-based guidelines for remediation and introduces risk management practices to minimize exposure and protect human health.

By taking this course, you will gain practical knowledge in evaluating and managing risks at contaminated sites. This knowledge will enable you to make informed decisions about remediation, risk management and exposure control. You will leave with a toolkit of skills for addressing site-specific challenges and ensuring compliance with environmental regulations.

Who Should Attend
This course is designed for a wide range of Environmental engineers and scientists who will benefit from a deeper understanding of the legal frameworks and technical methodologies required for effective site assessment and risk evaluation. Consultants working on contaminated site projects will gain valuable insights into developing risk-based guidelines and implementing management strategies.

Industrial staff, including technicians and technologists responsible for on-site environmental monitoring and remediation efforts, will find the course content essential for enhancing their exposure evaluation and risk management skills. Regulators and government officials tasked with reviewing and approving environmental risk assessments will gain a thorough understanding of the latest assessment techniques and risk management approaches, ensuring compliance with regulatory standards.

This course is also beneficial for project managers overseeing environmental aspects of land development projects, as it provides critical knowledge needed to interpret risk assessment results and integrate them into project planning and execution. Environmental health and safety professionals seeking to enhance their expertise in risk assessment frameworks and decision-making processes will find the course particularly valuable.
