Alcoa Vancouver
Cleanup construction at this site is complete and it is now being monitored. Monitoring can include a variety of activities, from regular checks to ensure cleanups are still effective to maintaining equipment that removes contaminants over time, such as soil vapor extraction systems.
See the Site Details Report at left or the documents below to learn more about this site.
Ecology works to clean up contaminated properties throughout the state. Cleanups are construction projects that remove, treat, or contain potentially harmful substances.
Site use restrictions called institutional controls are in effect
Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.
Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
