Last week, the Iowa Department of Natural Resources created an online map that allows Iowans to see if their drinking water is safe. The online map shows if cancer-causing chemicals have polluted water.
PFAS, also known as perfluoroalkyl and polyfluoroalkyl, are synthetic chemicals contaminating the state’s water. These chemicals are found in everyday household items like stain-resistant furniture and clothes, non-stick pots and pans, and more.
The DNR had tested around 59 cities for traces of PFAS. West Des Moines had the highest concentration of PFAS. Due to the findings, one of the three wells was shut down.
The map doesn’t show PFAS that were found in drinking water. This was the case for Iowa City. The map marks the city with a green dot, indicating that no PFAS were detected. However, residents did their research and found one of the two PFAS. The chemicals were found in the Iowa City Sand Pit Pond, a source of drinking water for 10% of the city’s water supply.
The supervisor of the DNR’s water quality bureau Roger Bruner said the DNR map shows the contamination of PFAS in finished drinking water that goes out to customers. To be transparent, test results of water sources can be found online.
