California is no stranger to drought, it’s a recurring feature of our climate, especially in desert areas. Arizona has been in some stage of drought since 1994(!), so drought is a long-term concept in the West. Many shifts are made for the purpose of water conservation, one of which is in landscaping. With these dry times saw a large uptick in fake lawns. 

In a recent controversial move, California Governor Gavin Newsom vetoed a bill aimed at restricting the use of “forever chemicals” in synthetic lawns. The veto highlights the state’s complex stance on artificial turf, as it was a material once promoted as a water-saving solution during droughts. The vetoed bill was part of a broader effort to address health concerns associated with synthetic turf, particularly the presence of perfluoroalkyl and polyfluoroalkyl substances (PFAS). These chemicals, found in the crumb rubber base of artificial turf, have been linked to various chronic diseases. Despite growing worries about the environmental impact and health risks, manufacturers claim they are working to address concerns by exploring alternative materials. However, removing PFAS entirely has proven challenging.

The debate over synthetic turf in California reflects a shift in legislative priorities, with some cities already moving to ban artificial lawns due to environmental concerns. Researchers emphasize the potential health risks associated with PFAS, which can enter the human body through various pathways, including skin contact, inhalation, and water contamination.

Studies indicate that high temperatures can cause chemicals to leach out of the crumb rubber base, posing additional risks to human health. Synthetic turf, known for its heat-retaining properties, can reach temperatures significantly higher than living grass, making it a cause for concern. Experts suggest that real grass and plants offer a more sustainable and environmentally friendly alternative to synthetic grass. Drought-friendly landscaping options, such as warm-season grasses and native plants, provide cooling benefits and contribute to a healthier urban ecosystem.
