Areas previously used for industrial or commercial purposes that may be contaminated with hazardous substances or pollutants are a significant concern in urban planning and environmental management. These sites often present challenges due to the potential presence of environmental hazards, hindering redevelopment and contributing to urban blight. An example includes a former gas station site where leaking underground storage tanks have contaminated the soil.
Addressing these impacted locations offers numerous advantages, ranging from revitalizing urban areas and increasing property values to protecting public health and the environment. Remediation and redevelopment can create jobs, generate tax revenue, and provide valuable community amenities such as parks or affordable housing. Historically, neglect of these locations has exacerbated environmental injustices, disproportionately affecting marginalized communities.
