Comprehensive Risk Assessment and Monitoring of Environmental Chemicals in Thailand

DESCRIPTION

This report highlights the risk assessment and monitoring strategies employed for environmental chemicals in Thailand, particularly after a contamination incident at Hua Hin Airport where chemical solutions leaked, resulting in soil contamination with dioxins, pesticides, arsenic, and Dicamba. Contaminated soil was safely excavated and placed in a secure landfill. It also discusses the establishment of groundwater and soil quality standards, including the regulation of VOCs, heavy metals, and pesticides, and ongoing efforts to finalize soil quality standards and develop contaminated site management guidelines.

  1. Risk Assessment and Monitoring for Environmental Chemicals SURIN AREE Environmental Scientist Thailand

  2. Treatment Technologies • Secure Landfill • Drums containing chemicals solution were damaged at Hua Hin Airport • Resulted to soil contamination • Dioxins, pesticides, arsenic and Dicamba were identified • Contaminated soil was contained on-site by excavation and placing in secure landfill

  3. My Experience on Risk Assessment and Monitoring Environmental Chemicals • Establish Groundwater and Soil Quality Standards • Groundwater quality standard become the regulation in October 2000 • The limitations of VOCs, heavy metals, pesticides and others [CN-, PCBs, benzo(a)pyrene] • Soil quality standard is on the process to be a legislation

  4. My Experience on Risk Assessment and Monitoring Environmental Chemicals (continued) • Monitor Chemical Contaminants Leaching from Municipal Landfills • Groundwater in monitoring wells was collected, analyzed, and compared to groundwater standard for drinking purposes • Parameters analyzed: heavy metals

  5. My Experience on Risk Assessment and Monitoring Environmental Chemicals (continued) • Develop Contaminated Site Management Guidelines
