Elevated levels of PFAS have been found recently in artificial turf, according to https://www.bostonglobe.com/metro/2019/10/09/toxic-chemicals-found-blades-artificial-turf/1mlVxXjzCAqRahwgXtfy6K/story.html

"The U.S. Environmental Protection Agency (EPA) took the next step to implement an important per- and polyfluoroalkyl substances (PFAS) requirement of the National Defense Authorization Act (NDAA). The NDAA added 172 PFAS to the list of chemicals required to be reported to the Toxics Release Inventory (TRI) and established a 100-pound reporting threshold for these substances.

“'EPA continues to prioritize and make progress to protect the health and well-being of communities across the country that are working to address PFAS,'” said EPA Administrator Andrew Wheeler. “'The inclusion of these 172 PFAS on the TRI list will provide EPA and the public with important information on these emerging chemicals of concern.'”

As this action is being taken to conform the regulations to a Congressional legislative mandate, this rule is effective immediately. Per the NDAA requirements, the PFAS additions became effective as of January 1, 2020. Reporting forms for these PFAS will be due to EPA by July 1, 2021, for calendar year 2020 data. EPA expects to release raw data from information collected by July 31, 2021."
