South Dakota State University begins testing surface water for per and polyfluoroalkyl substances, also known as forever chemicals. These chemicals stay in the environment for a long time and can also remain in the human body.
PFAS are found in many everyday products such as nonstick cookware, food packaging, some fabrics, and personal care items. These chemicals resist heat and repel water and oil. Because of these properties, PFAS have been widely used for many years.
PFAS are already found in South Dakota surface water, including the Big Sioux River. Studies show that a large portion of the nation’s drinking water contains some type of PFAS. Research also links PFAS to health concerns such as growth problems and higher cancer risk.
SDSU does not currently have a certified lab for PFAS testing in the state. As a result, water samples are often sent to labs outside South Dakota. SDSU now works to become certified so testing can be completed within the state.
The university has the special equipment needed for PFAS testing. Support from local water groups helps SDSU move toward official certification, which is expected in early two thousand-twenty-six. Once certified, the lab will serve water districts, agencies, and researchers across the state.
The new lab will focus on testing surface water samples. State agencies plan to certify another lab for drinking water testing.
SDSU researchers also plan to expand PFAS research. Future studies may include testing biosolids, which are used on farmland to return nutrients to the soil. PFAS in biosolids may raise new safety concerns.
Researchers are also preparing community studies to learn how PFAS exposure may affect human health. These studies may focus on links between PFAS and brain health.
By offering state PFAS testing, SDSU supports safer water, stronger research, and improved protection for communities across South Dakota.
