  2. Private wells and non-community water supplies weren’t part of the statewide PFAS testing program, necessitating individual testing for these sources.
  3. Community water supply test results offer valuable insights into potential PFAS contamination levels, aiding in informed decision-making.
  4. Accessing water testing results is possible through IEPA’s Drinking Water Watch platform or the PFAS Interactive Dashboard. Additionally, individuals can reach out to the Illinois Department of Public Health (IDPH) or local health departments for guidance on conducting their own PFAS water testing.

Removing PFAS From Water

filtering out harmful chemicals

Carbon filtration and reverse osmosis stand out as effective technologies for removing PFAS from water, with point-of-use filters and under-sink systems showcasing efficiency in reducing contaminant levels.

The success of these treatment methods hinges on the initial concentration of PFAS in the water, underscoring the importance of selecting appropriate NSF-certified systems and adhering to maintenance protocols for optimal removal outcomes.

Considerations such as adsorption capabilities, system installation, and ongoing monitoring play crucial roles in the successful mitigation of PFAS in drinking water.

Filtration Methods Overview

For effectively removing PFAS from water, consider utilizing carbon filtration or reverse osmosis as recommended treatment technologies.

When dealing with PFAS contamination in drinking water, it’s essential to understand the available filtration methods.

Here are some key points to consider:
