What Are the Risks at the Site?
Wood treatment activities at the site resulted in the production of creosote-contaminated sludges, sediments, process residuals, preservative drippings, and spent process liquids, and included two unlined canals that conveyed the creosote waste to two unlined storage lagoons. Extensive sampling by the EPA revealed that creosoting materials were not removed prior to the construction of the Claremont Development and Rustic Mall. The lagoon sludge and canal wastes were highly contaminated source material that posed a risk to current and future residents. The primary routes of exposure included: dermal contact with contaminated sludge and soil, and ingestion of groundwater contaminated by source material. The implemented actions in Phases 1, 2, and 3 of the Site cleanup have rendered the Site protective of human health and the environment by controlling all exposure pathways that could result in unacceptable risks, and through the prevention of direct exposure to contaminated materials and ingestion of contaminated groundwater.
EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

|Status at this
|What does this mean?|
|Human Exposure Under Control||Yes||Yes means assessments indicate that across the entire site:
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
|Groundwater Migration Under Control||Yes||
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use||Yes||Yes means:
No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
