Artificial Turf Fields
-
Artificial turf fields are made from plastic, an unsustainable product made from a combination of fossil fuels and chemicals, many of them toxic to humans. These multi-ton plastic fields cannot be recycled when worn out, and contribute to our worldwide plastic pollution problem.
-
Most artificial fields use rubber from recycled tires ("crumb rubber") to infill spaces between plastic grass blades, cushioning the surface. Chemical toxins cannot be removed from recycled tires, and exposure to this hazardous waste material presents significant potential human health risks. This type of infill material has been banned in some countries.
-
Most artificial turf fields contain per- and polyfluoroalkyl substances ("PFAS") that are required for the manufacturing process. These "forever" chemicals have been linked to a growing list of serious human health illnesses and conditions as well as environmental degradation.
-
Artificial turf fields absorb heat from sunlight and don't have the natural cooling mechanisms of grass, causing the field surface to reach dangerously high temperatures on hot days. This can create unsafe playing conditions, limit field availability and require large amounts of water to cool playing surfaces.
-
High lead and other toxic chemical levels have been detected in aging artificial turf fields made from nylon and polyethylene. Sun and wear break down the turf fibers into a dust contaminated with lead that can be rubbed off onto hands or other parts of the body. Lead is a proven and potent neurotoxin, and children are particularly vulnerable to its effects.
-
Artificial turf fields require the use of pesticides to treat body fluids that grass fields take care of naturally. For more information, see our page on turf pesticides.
Note: We strongly recommend that all schools and municipalities require artificial turf suppliers to obtain, possess and hold substantial liability insurance in the event of a claim for harm or injury from the use of the field, or environmental pollution as a result of its wear and physical degradation.

When their town leadership passed ordinances to install artificial turf fields, concerned residents in Westfield and Scotch Plains, NJ, created petitions and collected enough signatures that the bond ordinances were brought to a public vote. Both towns rejected the referenda in 2023, citing cost and environmental concerns.
The city of Cape May, NJ, has banned the installation of artificial turf as an alternative to natural landscaping.
The Oaks Bluff health board on Martha's Vineyard voted down artificial turf, citing concerns about the town's drinking water and federal regulations on PFAS. Years earlier, the school board had decided not to proceed with the installation of artificial turf fields, and upgrade their grass fields instead. A presentation by the Field Fund about this project can be found on the Rye, NY, municipal website.
The South Orange-Maplewood, NJ, board of school estimate voted down turf, saying the project was not fiscally or environmentally responsible. They want the district to consider a natural grass playing field instead.
The City of Boston has halted the installation of artificial turf fields because of concerns about PFAS "forever chemicals" and their potential impact on the health of young athletes.
The Board of Health of Amherst, MA, voted against the installation of an artificial turf field at the high school over health concerns.
Arlington, MA, published a cost and maintenance analysis of artificial turf versus natural grass on their website.
