OVERVIEW

  • The Santa Susana Field Lab is a headwater for the Los Angeles River and reaches Ventura County’s Calleguas Creek Watershed through the Arroyo Simi. Both watersheds terminate at the Pacific Ocean.

  • When it rains, the Santa Susana Field Lab can discharge 187,000,000 gallons of contaminated rainwater from the site into local waterways per day.

  • The Santa Susana Field Lab is located on a plateau — contaminated water from the site naturally wants to flow down to the communities in the valleys below.

  • Boeing has been fined over $1,000,000 for polluting local waterways with contamination from the SSFL.

  • 30% of Simi Valley residents drink a blended water mix from Golden State Water with water from wells that the EPA has stated are at risk of being contaminated by the SSFL.

Local Watersheds

The Santa Susana Field Lab is connected to two tributary (contributing) waterways of important watersheds in Southern California.

The backside of the SSFL drains into the Arroyo Simi (without being filtered first), a tributary of the Callagues Creek Watershed.

The Calleguas Creek Watershed is used for:

  • Drinking water

  • Recreation

  • Fishing

  • Agriculture

  • Supports wildlife

  • Reaches the Pacific Ocean

The SSFL is a headwater of the Los Angeles River. The LA River Watershed is far-reaching, making it important to prevent impact from contamination at the SSFL as it has the potential to impact millions of Angelinos.

The LA River Watershed is used for:

  • Recreation

  • Fishing

  • Supports wildlife

  • Reaches the Pacific Ocean
