Land-based spills can originate from a variety of industrial, transportation, and storage activities. Leaks from storage tanks, whether above-ground or underground, are common culprits, often caused by corrosion, equipment failures, or inadequate maintenance. Accidents during loading, unloading, or transporting oil via trucks, pipelines, or railcars can lead to spills.
Construction activities, such as drilling or excavation near pipelines or storage facilities, also pose spill risks. Industrial facilities handling oil, such as refineries and manufacturing plants, may experience spills due to process malfunctions or human errors. Improper disposal or mishandling of used oil and lubricants can lead to contamination.
