Ellsworth Air Force Base Water Contamination Lawsuit Overview

Ellsworth Air Force Base originated as Rapid City Army Air Base in 1942. It was home to training operations for the B-17 bomber crews and became a permanent facility in 1948 under the 28th Strategic Reconnaissance Wing. After the death of General Richard E. Ellsworth, the Wing’s commander, the base was renamed Ellsworth Air Force Base in his honor. Throughout its history, the base has supported aircraft and missile operations and currently hosts the 28th Bomb Wing. 

Ellsworth AFB covers around 4,858 acres of land in Meade and Pennington counties in South Dakota. It has a population of 15,900 people including 3,000 military personnel, 3,500 family members, 8,100 retirees, and 1,000 civilians. Throughout its lifetime, military activity at Ellsworth has caused air, groundwater, and soil contamination. One of the largest contaminants of concern, PFAS, is a group of chemicals found in firefighting foam (Aqueous Film Forming Foam or “AFFF”) that was frequently used at Air Force bases for training exercises and to put out fires caused by plane crashes and other incidents. If consumed, PFAS can cause testicular cancer, bladder cancer, pancreatic cancer, and several other life-threatening conditions. If you’ve been diagnosed with a PFAS-related condition, you may be eligible to file a claim for compensation.

Ellsworth Air Force Base Water Contamination Lawsuit Updates

May 2024 – More Veterans File Ellsworth AFB Toxic Exposure Lawsuits

Over the past couple of years, there has been a growing number of toxic exposure lawsuits filed against PFAS product manufacturers. Many of these cases involve veterans who served at Ellsworth Air Force Base where TCE, PFAS, and other chemicals from military activities led to diagnoses of cancer, ulcerative colitis, and other conditions. 

King Law is now reviewing cases where individuals were exposed to toxins at Ellsworth and other military bases. We’re dedicated to representing military veterans, their families, and other residents who have been impacted by water contamination and are now seeking compensation to help with treatment costs and more. 

April 2024 – First Enforceable PFAS Limit Confirms Long-Standing Safety Concerns

While the dangers of PFAS have been known since the 1970s, there have not been enforceable limits in place until April of 2024. The EPA’s original Lifetime Health Advisory for PFOA/PFOS (two types of PFAS) was 70 ppt. However, the EPA has since set an enforceable Maximum Contaminant Level of 4 ppt for PFOA and 4 ppt for PFOS. Some PFOS/PFOA levels at Ellsworth AFB have tested over 4,600 ppt. The EPA’s new limits confirm widespread concerns that the PFAS impact has been much larger than early samples suggested.

History of Toxic Exposure at Ellsworth Air Force Base

Ellsworth Air Force Base has dealt with water contamination since the 1990s. While TCE was the largest priority for cleanup efforts, 2016 brought PFAS contamination to light. Decisions to cleanup PFAS in water were largely made based on exceedances of the EPA’s 70 ppt advisory. However, the new enforceable limit is 4 ppt for PFOA and 4 ppt for PFOS, which is much lower than the original LHA. 

2023 – Air Force Starts Transitioning to Safer Firefighting Foam Alternative 

In September 2023, a fluorine-free firefighting foam was presented by the Department of Defense (DoD). According to the latest PFAS updates from Ellsworth AFB, “the Air Force has started the transition process.” The Air Force has also removed AFFF tanks from hangar fire suppression systems, used the foam in double-lined pits to avoid soil and groundwater contamination, and treated any uncontained AFFF releases as a hazardous spill for rapid cleanup. 

2020 – Groundwater PFAS Levels Near Ellsworth AFB Test More Than 60 Times Lifetime Health Advisory 

In an effort to confirm TCE contamination was addressed in groundwater just east of the base, the Air Force took a series of water samples. PFAS levels were above the LHA in 25 of the 30 wells with PFOS concentrations as high as 4,680 ppt and PFOA concentrations as high as 320 ppt. 

2019 – Air Force Seeks to Identify Solution to PFAS Drinking Water at Ellsworth 

The Air Force contracted a company in 2019 to find drinking water alternatives for residents with water samples testing above the PFAS LHA. The plan for a proposed alternative was set to be provided to the EPA and South Dakota Department of Environment and Natural Resources in 2020. 

2018-2019 – Off-Base Investigation Finds High Levels of PFAS In Resident Wells

An investigation into off-base PFAS contamination that had migrated from Ellsworth was conducted September 2018-March 2019. Of the 112 private drinking wells that were sampled, 22 had PFAS levels above the LHA and 91 residents were given alternate drinking water. 

2016-2017 – PFAS First Identified at Ellsworth AFB

The Air Force first discovered PFAS groundwater contamination at Ellsworth AFB in 2016. The base stopped using PFAS-containing firefighting foam the same year but the chemicals had already entered groundwater and migrated to surrounding communities. In 2017, the Air Force sampled wells east, south, and west of the base. They found 30 properties with PFAS levels exceeding the 70 ppt LHA.

Our Ellsworth Air Force Base water contamination shows the base layout and location of known chemical plumes. The visual also highlights key areas that were identified through Superfund site assessment and remediation efforts. Most areas of concern are fire training sites, landfills, and storage areas. This is where products like PFAS-containing firefighting foam were used, stored, and disposed of, leading to groundwater contamination. 

Contaminants Found in Ellsworth Air Force Base Drinking Water

Ellsworth Air Force Base has struggled with dozens of different contaminants in soil and groundwater. Some of the largest chemicals of concern have included benzene, TCE, and PFAS. Long-term exposure to these chemicals increases health risks and often the severity of illnesses. 

Per- and Poly-Fluoroalkyl Substances (PFAS)

Per- and poly-fluoroalkyl substances (PFAS) are a group of chemicals that were used in firefighting foam for decades. This foam was used to maintain and put out fires that would occur during training, plane crashes, and other fire emergency situations. In many cases, it would be sprayed directly on the ground, causing the chemicals to seep into the soil and groundwater. Drinking water with PFAS can cause:

  • Birth defects
  • Bladder cancer
  • Breast cancer
  • Changes in liver enzymes 
  • Decreased vaccine effectiveness
  • Hodgkin’s and non-Hodgkin’s lymphoma
  • Leukemia
  • Lowered immune response 
  • Multiple-myeloma
  • Kidney cancer 
  • Pancreatic cancer 
  • Prostate cancer 
  • Reproductive issues
  • Testicular cancer 
  • Thyroid cancer 
  • Thyroid disease 
  • Ulcerative colitis

Also known as “forever chemicals,” PFAS build up in the body over time and don’t break down. So the longer military personnel were exposed, the higher their risk of developing a life-threatening condition. 


Groundwater and soil at fire training areas and landfills at Ellsworth AFB have been flagged by the EPA for benzene contamination. There are many different symptoms of benzene exposure that can emerge right away, such as dizziness, sleepiness, irregular heartbeat, and convulsions. Long-term health effects are much more severe, including: 

  • Anemia
  • Decrease in red blood cells 
  • Decreased immune function
  • Excessive bleeding
  • Increased risk of infection
  • Reproductive issues 
  • Leukemia

Trichloroethylene (TCE)

Trichloroethylene (TCE) is a chemical found in degreasers and solvents often used when repairing and maintaining equipment like military planes. TCE contamination has been an issue at Ellsworth Air Force base since the 1990s with a known connection to

  • Cervical cancer 
  • Cancer of the lymphatic system
  • Heart disease 
  • Kidney cancer 
  • Liver cancer 
  • Nervous system problems 
  • Neurological problems 
  • Reproductive issues 

Current Water Quality at Ellsworth Air Force Base

Ellsworth Air Force Base still has contaminated water. Permanent efforts to provide safe water sources faced setbacks due to waterline permit issues in 2022 with construction now planned to start in 2024. Over the past decade, veterans at the base, their family members, and residents on and near the base have consumed contaminated water and either have developed or are at risk of developing a range of illnesses. 

Water Treatment Efforts at Ellsworth Air Force Base

The Air Force has been working to provide residents with safe drinking water for the past several years, while leveraging treatment systems and new waterline plans. They’ve provided bottled water to residents with PFAS-contaminated water and continue to monitor water samples on- and off-base. In addition, a remedial investigation is underway at the base to understand the true extent of PFAS contamination.
