Ecology is entering into an Agreed Order with multiple parties to clean up contamination related to historic industrial activities at the Port of Longview. In the past, the Port of Longview TPH site was used to transport and store petroleum products. Practices associated with the handling of petroleum and leaks from storage tanks and underground pipelines have contaminated soil and groundwater. Contaminants identified so far include:
Total petroleum hydrocarbons (TPH) in the gasoline and diesel carbon ranges.
Volatile organic compounds (VOCs), such as BTEX (benzene, toluene, ethylbenzene, and xylene)
Polycyclic aromatic hydrocarbons (PAHs)
After long-term exposure, these chemicals can be harmful to the health of people and the environment.
