Pipeline transport oil-contaminated sediment and debris from the Kalamazoo River system. However, oil was still being found in affected waters in October 2012. Fossil fuels can be transported by pipeline, rail, truck, or ship, though natural gas requires compression or liquification to make vehicle transport economical. For transport of crude oil via these four modes, various reports rank pipelines as proportionately causing less human death and property damage than rail and truck, spilling less oil than truck, and having more environmental impact than truck or rail (mostly due to impact on habitat; ship transport impacts marine habitat to a large degree). Pipelines
Pipeline transport rain. They are protected from nesting birds, rutting mammals, and stray buckshot. Buried pipe is less vulnerable to accident damage (e.g. automobile collisions) and less accessible to vandals, saboteurs, and terrorists. Previous work has shown that a 'worst-case exposure scenario' can be limited to a specific set of conditions. Based on the advanced detection methods and pipeline shut-off SOP developed by TransCanada, the risk of a substantive or large release over a short period of time contaminating groundwater with benzene is unlikely. Detection, shutoff, and remediation procedures would limit the dissolution and transport of benzene. Therefore, the exposure of benzene
