McClellan Air Force Base Water Contamination

Originally commissioned as the Sacramento Air Depot in 1936, McClellan Air Force Base would serve communities of Northern California for over 60 years until its official closure in 2001. In 1939, the military installation’s name was changed to honor Maj. Hezekiah McClellan. While open the base supported air operations throughout the Western Coast of the United States. It also served as a staging area for aircraft and Pacific-bound material. 

Since its closure, the base has been converted to a business park. The former base, however, has come under scrutiny because of environmental contaminants that have affected the groundwater and soil at and near the installation. Over $500 million has been poured into clean up efforts with another $400 million anticipated to be spent for the project. 

Individuals, however, who were stationed at the base may have been exposed to toxic water. The contaminants at McClellan Air Force Base may cause significant health problems including an increased risk of cancer. If you or a loved one were stationed at McClellan Air Force Base and subsequently diagnosed with an illness related to toxic water exposure, you may be entitled to compensation. It is strongly recommended that you speak with an attorney.

Water Contamination Updates at McClellan AFB

May 2024: Investigations continue into water contamination at and near McClellan Air Force Base. Servicemembers who were stationed at the base for at least six months and were subsequently diagnosed with an illness related to toxic water exposure, are strongly encouraged to contact a military base water contamination lawyer as soon as possible

April 2023: Clean-up efforts continue at the former McClellan Air Force Base after sampling of groundwater at the indicates the presence of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA), two common Perfluoroalkyl and polyfluoroalkyl substances (PFAS). PFAS are forever chemicals that may cause serious harm to humans and the environment. 

McClellan Air Force Base: History of Toxic Exposure

According to the Air Force Civil Engineer Center, contamination in the groundwater at McClellan Air Force Base was originally discovered in 1979. After extensive investigation a wide range of contaminants were detected at the installation including volatile organic compounds (VOCs). Due to the extensive contamination, use of the groundwater for drinking water is prohibited.

In 1987, the base was added to the National Priorities List as a “Superfund” site by the U.S. Environmental Protection Agency (EPA). While the base was officially closed in 2001, cleanup efforts continued as a result of the contamination. Sampling of the groundwater within the last five years determined the presence of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). These two common perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been linked to an increased risk of cancer. 

It is believed that PFAS contamination was the result of the Air Force’s use of Aqueous film forming foam (AFFF). AFFF is a fire-suppressant that was used for decades in training and to extinguish high hazard fires. 

Where the Contamination Was on McClellan Air Force Base

McClellan Air Force Base consists of 3,452 acres in the North Highlands area of Sacramento, California. Cleanup efforts at the installation identified 326 waste areas

While VOCs and other contaminants were detected throughout the base. High levels of PFAS were detected at sites like ​​the former Ammunition Storage Area (current Areas of Concern (AOC) 314), former waste disposal (Confirmed Site (CS) 043) and burn pit and sludge/oil pit sites (Potential Release Location (PRL)) as well as CS 052 and CS 067 and the former burn pit site (CS 069).

What Contaminants Were Found at McClellan Air Force Base?

There are several contaminants found in the groundwater and soil at McClellan Air Force Base. In 1979, volatile organic compounds (VOCs) were discovered on the base. These compounds are believed to be the result of cleaners and solvents used at the installation for decades. 

In addition to VOCs, subsequent groundwater sampling showed the presence of PFAS. PFAS are forever chemicals. PFAS exposure has been linked to substantial harm and an increased risk of certain kinds of cancer.

  • In 1987, the Air Force installed extraction wells and implemented a groundwater treatment plan. The base was also listed on the National Priorities List as a “Superfund” site.
  • Installation of groundwater pump and treat system in the mid-1980s. To date over 100 extraction wells and 500 monitoring wells have been installed at the site. 
  • Soil vapor extraction systems were installed at McClellan in 1993. Over one million contaminants have been removed through these systems.
  • The remediation method of dig and haul has also been used at the site. This method includes the removal and disposal of the soil and the contaminants. 
  • Protective capping was implemented at McClellan followed by continued monitoring and review of samples at the base.
