Former Athens Tank Farm

Two construction workers in the street

ExxonMobil has always been committed to a thorough environmental investigation and remediation (cleanup) relating to the former Athens Tank Farm, located on 122 acres in the Willowbrook area of Los Angeles County (the “Site”). Today, the Site is occupied by the Earvin Magic Johnson Regional Park (“Park”).

The Los Angeles Regional Water Quality Control Board (“Regional Board”) and the California Department of Toxic Substances Control (DTSC) are jointly overseeing Site activity. The Regional Board is leading the Site investigation, monitoring, and cleanup. The DTSC is leading aspects relating to health risk assessment, indoor air sampling activities, and community outreach.

Under the oversight of these two agencies, ExxonMobil has investigated soil, soil gas, and groundwater impacts at the Site and the surrounding neighborhood, and has started a cleanup process.

We encourage members of the community to use this website to learn more about the progress of our investigation and for updates on community activities.

Ujima Village Q&A

Q: Am I getting sick by living here? (pt 1)

A: Current science does not allow us to tell you if cancers that have already occurred were caused by something. But what we can say is there are not chemicals today that are causing harm. The concentration of chemicals in soil and air is not significant enough to present a health problem today or in the future. We can't attribute any cancer to conditions at the site, but we can tell you all the science says conditions at the site are not presenting a risk today.

Hexane does not cause cancer.

Our commitment

ExxonMobil takes its environmental responsibilities very seriously. Since we were first informed of potential contamination concerns, ExxonMobil has been working with the Regional Board and agencies to conduct an extensive environmental investigation at the former Ujima Village.


Our work so far

“The initial results at this time indicate no potential adverse indoor air quality impacts as a result of petroleum hydrocarbon vapor intrusion.”
