Per- and Polyfluoroalkyl Substances (PFAS) in Harford County Public Schools: A Growing Concern
Introduction
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in a wide range of products, including nonstick cookware, waterproof clothing, and firefighting foam. In recent years, there has been growing concern over the potential health effects of PFAS exposure, and several studies have linked PFAS to a variety of health problems, including cancer, birth defects, and immune system dysfunction.
PFAS in Harford County Public Schools
In 2018, the Maryland Department of the Environment (MDE) conducted a study of PFAS levels in drinking water at 28 Harford County Public Schools. The study found that PFAS levels exceeded the Environmental Protection Agency's (EPA) health advisory level of 70 parts per trillion (ppt) in 11 of the schools. The highest PFAS level was detected at Aberdeen High School, where the concentration was 470 ppt.
Health Effects of PFAS Exposure
Exposure to PFAS can occur through drinking contaminated water, eating contaminated food, or breathing contaminated air. PFAS can also be absorbed through the skin. Once in the body, PFAS can accumulate and remain for long periods of time. Exposure to PFAS has been linked to a variety of health problems, including:
- Cancer
- Birth defects
- Immune system dysfunction
- Kidney damage
- Liver damage
- Thyroid problems
- Neurological problems
What is Being Done to Address PFAS in Harford County Public Schools?
In response to the MDE study, Harford County Public Schools has taken a number of steps to address PFAS contamination in its schools. These steps include:
- Installing water filters in all schools where PFAS levels exceed the EPA health advisory level.
- Providing bottled water to students and staff at schools where PFAS levels exceed the EPA health advisory level.
- Conducting additional testing to identify the source of PFAS contamination.
- Working with the MDE to develop a long-term plan to address PFAS contamination in Harford County.
What Can You Do to Protect Your Child from PFAS Exposure?
There are a number of things you can do to protect your child from PFAS exposure, including:
- Get your child's drinking water tested for PFAS. If PFAS levels exceed the EPA health advisory level, consider using a water filter to remove PFAS.
- Avoid giving your child food that is packaged in PFAS-coated containers.
- Do not allow your child to play on or near areas where PFAS-containing firefighting foam has been used.
- Teach your child about the health effects of PFAS and how to avoid exposure.
Conclusion
PFAS contamination is a serious problem that poses a significant threat to the health of our children. Harford County Public Schools is taking steps to address PFAS contamination in its schools, but there is still more that needs to be done. You can help to protect your child from PFAS exposure by taking the steps outlined above.
