This assignment analyzes a case study of a contaminated land site. It examines the source of contamination (toluene from waste lagoon sludge), discusses various in situ and ex situ remediation technologies suitable for addressing the issue, and evaluates their performance based on factors like technological readiness, community acceptance, and secondary treatment requirements. The assignment also outlines site management actions to minimize contaminant spread, such as improved security and exposure notification. Finally, it highlights the link between land use, human activities, and the level of contamination present.
