Plastic fields are highly problematic for athletes, taxpayers, and the environment alike. From injury risk, high temperatures and toxic exposures to exorbitant costs, plastic pollution, greenhouse gas emissions and more, plastic fields are not the answer to neglected grass fields. We can enjoy sports in nature not at the expense of it.


Do we really need plastic fields? No. Well-maintained natural grass fields are durable, drought resistant and affordable, can drain efficiently and be rejuvenated. Updated maintenance protocols should reflect current best practices – a nontoxic, systems-based approach that avoids synthetic inputs and runoff. The first questions should always be: how are the existing natural grass fields currently being maintained and utilized?

Why choose a more expensive, plastic version of the real thing? As The Field Fund is already proving, natural grass is significantly cheaper to install and maintain. According to UMass Lowell’s Toxics Use Reduction Institute (TURI), 25 and 50-year lifecycle costs for plastic fields, particularly with expensive alternative infills, are at least 3x as large as those for natural grass. Note: These costs do not include the $150,000+ shock pad now considered mandatory for any plastic field nor do they account for the high premature failure rates of plastic fields. Plastic fields financially burden taxpayers, indefinitely!

Aren’t we trying to minimize waste? Yes. It is estimated that over 90% of plastic carpets go into landfills. There is no recycling facility in the U.S. Each plastic carpet is more than 40,000 lbs of synthetic material (and the infill can include an additional 400,000+ lbs pounds of synthetic material, depending on the type) creating massive solid waste every single time the system needs replacement.

Does anyone really know what the long-term impacts of plastic leachate are? No. Plastic has not been around long enough for science to identify the full impacts of its pollution. We do know that the plastic carpets are petrochemical products typically made with endocrine disrupting PFAS, phthalates and flame retardants, uv stabilizers, lead, and other heavy metals, and treated with herbicides and antimicrobial agents. And we know that as the acres of plastic "grass" fibers shed and break down, the particulate from all those materials migrate into groundwater and soils (and into our childrens’ developing bodies), until the carpet must be disposed of and replaced, and the cycle begins again. We also know that that they off-gas huge amounts of methane (20x more potent than carbon dioxide) and ethylene, accelerating as the plastic fibers fragment. By contrast, a healthy natural grass field traps dust and dirt, reduces pollution and runoff, filters stormwater excess, and reduces sediment and pollutants from entering waterways.

Did you know plastic field systems are not regulated for use by children? The Consumer Product Safety Commission (CPSC) does not regulate plastic field systems as children’s products. We cannot rely on industry to decide a safe level of toxic exposure to our children and environment. The UMass Lowell’s TURI, Environmental and Human Health, Inc. (EHHI), Mount Sinai’s Children’s Environmental Health Center, the EPA, and the CPSC have all admitted that plastic fields cannot be described as safe. Mass tort cases are already emerging.

But I’ve heard there’s science on both sides? No. It is commonly accepted that plastics pose a massive threat to planetary health. The studies cited by proponents of plastic fields reveal conflicts of interest and/or faulty methodology. Following the tobacco industry’s deceptive marketing playbook, the plastic field industry hires product defense consultants who cast doubt on any research that indicates health hazards of their clients’ products. The same firm, dubbed “rented white coats” in an investigative report, hired by the plastic field industry also defends materials like asbestos, arsenic and lead. Even a well known University’s research center has a partnership with the largest plastic field manufacturer.

Do you want your children exposed to toxins? No. Toxic PFAS chemicals were found in recently tested samples of new and used plastic field carpets. New studies have recommended that children not consume water with concentrations of PFAS chemicals greater than 1 part per trillion, calling the health risks greatly underestimated. One part per trillion is about as much as a grain of sand in an Olympic-size swimming pool. Further, the CDC and AAP state there is no safe level of lead. Under sworn testimony in March 2016, the plastic field industry admitted that their product still contains lead. According to the CDC, as the turf ages and weathers, lead (used as the color fixative) is released in dust that can then be ingested or inhaled. From its persistent use of ground tires to its largely undisclosed use of lead and PFAS, the plastic field industry has demonstrated an alarming disregard for human and environmental health. Other toxins including known endocrine disruptors and possible carcinogens can also be present in the plastic carpet, shock pad, and infill. And, according to owner’s manuals, other chemicals should be applied regularly to properly maintain the carpet. Anti-microbials (many of which have been banned by the EPA due to long-term health risks), herbicides, and biocides (used to clean vomit, spit, sweat, blood, and animal droppings), all eventually make their way into waterways and our children. Because plastic fields are made out of highly flammable petrochemicals, they are often pre-treated with flame-retardants. And children are more susceptible to environmental hazards because of their developing organ systems, immature detoxification mechanisms, proximity to the ground, frequent hand to mouth activity, and faster respiratory rates.

Are there other health risks? Yes. Plastic fields are made of petroleum-based fibers that absorb heat and can create a heat island effect, regardless of infill or frequent watering. The hottest temperature on record is 200F. Athletes can suffer from blisters, burns, dehydration, heat exhaustion and stroke, and even death. As fields heat, noxious materials can be absorbed in gases that can become 10-20x more toxic than the materials themselves. Players and researchers also note lower extremity injuries, turf toe, excessive hardness and slower recovery times. Healthy grass and soil, in contrast, provide a cooling effect, sequester carbon, naturally disinfect, and offer a range of positive benefits to physical and mental health.

Aren’t “natural” infills harmless? No. No alternative infill will solve the hazards associated with plastic fields. While some infills could be less toxic than others, this does not mean their dust is safe for children to inhale or that they adequately protect athletes from injury or heat-related problems. And because they are newer to the market, children and taxpayers are serving as guinea pigs. Most infills are used in conjunction with silica sand, a recognized carcinogen, and may be pre-treated with flame-retardants, anti-mold, anti-fungus, and anti-bacterial chemicals. They also require regular replenishment as tons (per field) of it migrate into the broader environment every year.

“When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause-and-effect relationships are not fully established scientifically. In this context the proponent of an activity, rather than the public, should bear the burden of proof.”
