The Santa Susana Field Laboratory (SSFL), located in Simi Valley, California, has a dark history of nuclear and chemical experimentation that has left a lasting impact on the environment and the health of local communities. For over five decades, the laboratory was the site of numerous nuclear and chemical tests, including rocket testing, nuclear reactor operations, and the development of nuclear weapons. The legacy of these activities has resulted in a toxic landscape of radioactive and chemical contamination that continues to pose significant risks to human health and the environment.
A History of Contamination
The SSFL was established in 1947 and was operated by various government agencies and private companies, including Rocketdyne, which was later acquired by Boeing. During its operational years, the laboratory was the site of numerous experiments and tests, including:
- Nuclear reactor operations: The SSFL was home to several nuclear reactors, including the Sodium Reactor Experiment, which suffered a partial meltdown in 1959, releasing radioactive materials into the environment.
- Rocket testing: The laboratory was used to test rocket engines and other aerospace equipment, resulting in the release of toxic chemicals and pollutants into the air and soil.
- Chemical testing: The SSFL was also used to test and develop various chemicals, including pesticides and other toxic substances.
Environmental and Health Impacts
The contamination at the SSFL has had significant environmental and health impacts. The site has been found to be contaminated with a range of toxic substances, including:
- Radioactive materials: The site is contaminated with radioactive isotopes, including cesium-137, strontium-90, and plutonium-239.
- Chemicals: The site is contaminated with a range of chemicals, including volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and pesticides.
- Heavy metals: The site is contaminated with heavy metals, including lead, mercury, and arsenic.
Exposure to these contaminants has been linked to a range of health problems, including:
- Cancer: Exposure to radioactive materials and chemicals has been linked to an increased risk of cancer, including leukemia, lymphoma, and other types of cancer.
- Neurological damage: Exposure to chemicals and heavy metals has been linked to neurological damage, including cognitive impairment, memory loss, and other neurological problems.
- Reproductive problems: Exposure to chemicals and heavy metals has been linked to reproductive problems, including birth defects, miscarriage, and infertility.
Community Impact
The contamination at the SSFL has had a significant impact on local communities, including:
- Residential contamination: Homes and neighborhoods surrounding the SSFL have been found to be contaminated with toxic substances, posing a risk to residents.
- Water contamination: The contamination at the SSFL has contaminated local water sources, including the Los Angeles River and groundwater aquifers.
- Economic impact: The contamination at the SSFL has had a significant economic impact on local communities, including reduced property values and lost economic opportunities.
Cleanup Efforts
Cleanup efforts at the SSFL have been ongoing for several decades, but progress has been slow. In 2010, the US Environmental Protection Agency (EPA) announced a comprehensive cleanup plan for the site, which includes the removal of contaminated soil and groundwater. However, the cleanup process has been delayed due to funding issues and disputes over the extent of the contamination.
In 2020, the California Department of Toxic Substances Control (DTSC) announced a new cleanup plan for the site, which includes the removal of all contaminated soil and the restoration of the site to a safe condition. However, the plan has been met with skepticism by local communities, who are concerned that it does not go far enough to address the full extent of the contamination.

The Santa Susana Field Laboratory’s toxic legacy is a stark reminder of the devastating consequences of nuclear and chemical experimentation. The contamination at the site has had a profound impact on the environment and human health, and it will take decades, if not centuries, to fully remediate. It is imperative that the cleanup efforts at the SSFL are completed as soon as possible, and that the site is restored to a safe condition to protect the health and well-being of local communities.
The story of the SSFL serves as a warning about the dangers of unchecked industrial and military activities, and the importance of prioritizing environmental and human health in our pursuit of scientific progress. As we move forward, it is essential that we learn from the mistakes of the past and work towards a safer, more sustainable future for all.
