Artificial turf is often marketed as a maintenance-free solution for lawns. However, behind its green façade lie several hidden risks.
Artificial grass promises lush, green lawns or playable fields without mowing or watering, making it popular among homeowners, sports leagues, and even some Florida municipalities. But in recent years, scientists and officials have raised alarms about the health, environmental, and safety hazards associated with synthetic turf. From toxic chemicals like PFAS “forever chemicals” to heat islands and injury risks, a growing body of evidence suggests the grass isn’t always greener on the artificial side.

Health Hazards: Chemicals and Contaminants in Turf
Modern artificial turf is made of plastic fibers and rubber infill that can contain or shed numerous harmful chemicals. Chief among these are per- and polyfluoroalkyl substances (PFAS) – a class of synthetic “forever chemicals” used to make products water and heat resistant. Public health advocates report that all artificial turf contains PFAS at potentially dangerous levels, since manufacturers have admitted they cannot produce the plastic grass blades or backing without them. When tiny PFAS particles break off the turf, players or residents can absorb them through the skin, inhale or ingest them, or get them in open wounds. PFAS exposure is linked to cancers, liver and thyroid problems, birth defects, kidney disease, immune suppression and other serious health issues. In fact, a preliminary 2024 study in California found that young soccer players had more than double the level of PFOS (one particularly toxic PFAS compound) on their skin after playing on artificial turf, whereas playing on real grass led to decreased PFOS levels. This suggests turf play can coat people in PFAS, adding to what scientists fear is a significant health threat. The U.S. EPA has even concluded effectively no level of PFOS in drinking water is safe, underscoring concern about any PFAS exposure.
Beyond PFAS, artificial turf and its infill often contain a host of other chemicals and heavy metals. Many fields and playgrounds use crumb rubber infill made from recycled tires, which can leach polycyclic aromatic hydrocarbons (PAHs) – carcinogenic compounds – as well as benzene, styrene, and volatile organic compounds (VOCs). This rubber and the turf backing have been found to contain lead, arsenic, cadmium, chromium, zinc, and other metals that can volatilize into air or wash into water. A 2024 systematic review of studies worldwide confirmed that median concentrations of eight PAHs and metals like cadmium, mercury, and zinc in turf materials often exceeded European safety limits, and some of these contaminants are bioaccessible, meaning they can be absorbed by the human body. The review noted cancer risks were identified for certain exposure scenarios (like children accidentally ingesting infill, or dermal/inhalation exposure to heavy metals) In other words, potentially hazardous levels of carcinogens and toxic metals are present in turf fibers and infill, even if real-world exposure varies. Health experts worry about long-term, cumulative effects: regular contact with turf – whether athletes sliding on a field or toddlers playing on fake grass playgrounds – may increase risks of cancer, endocrine disruption, or developmental issues from these chemicals.
Real-life concerns have prompted investigations. For example, a cluster of rare brain cancers among former pro baseball players from the Philadelphia Phillies has led some to suspect years of playing on synthetic turf (at Veterans Stadium) could be a factor. And the U.S. Centers for Disease Control has noted concern over lead exposure from older turf fields. While definitive causal links are hard to prove, the mounting anecdotal evidence and preliminary studies are alarming enough that many experts urge caution. The NFL Players Association has publicly called for all artificial turf fields to be replaced with natural grass for player safety, and some municipalities (including a few in Florida) have even banned or restricted artificial turf due to health and environmental worries. In short, the “chemistry” underfoot in artificial turf can introduce an unwelcome chemistry to our bodies.
Environmental Impact: Heat Islands, Pollution, and Ecosystem Disruption
Artificial turf doesn’t just pose invisible chemical hazards – it can also wreak havoc on local environments. One of the most immediate impacts is the heat island effect. Plastic grass lacks the natural cooling properties of real turf, which through evapotranspiration can dissipate heat. Instead, artificial surfaces absorb and radiate heat intensely. On sunny days, synthetic fields have been measured at 160°F or hotter, upwards of 60° higher than natural grass. Temperatures on turf can soar to 120–180°F, enough to melt shoe soles and cause second-degree burns in minutes. The New York City Health Department reported that heat is the primary health concern with turf, as field temps above 115°F can quickly lead to dehydration, heatstroke, or skin burns. Florida’s climate only amplifies this – under the intense Wellington or Palm Beach County sun, unshaded turf can become dangerously hot to touch. This doesn’t just endanger people (addressed more in the next section); it also contributes to urban heat islands. Hot turf radiates heat into the air, raising surrounding ambient temperatures and forcing nearby buildings to work harder on cooling. Homeowners may see higher AC bills and stressed air-conditioning near extensive artificial lawns, undermining any “green” benefit.
Runoff and water issues present another environmental challenge. Natural grass, with its root systems, acts like a sponge and filter during Florida’s frequent rains – it slows down stormwater, promotes infiltration to recharge groundwater, and traps pollutants. Artificial turf, by contrast, is typically installed over a compacted base (often gravel or concrete) with little to no permeability. Essentially, a synthetic lawn is as impervious as pavement. Rainwater flows off quickly, picking up debris and any loose infill particles, which can lead to localized flooding and burdened stormwater systems in heavy downpours. In South Florida, where managing stormwater to prevent floods and protect aquifers is critical, this is a serious concern. Bay area experts note that turf also fails to remove nutrients from runoff (unlike real grass which can uptake nitrogen and phosphorus), so fertilizer residue or animal waste can wash directly into waterways. Leaf litter or organic debris doesn’t decompose on plastic lawns either, often accumulating and creating further management issues or requiring removal. Worryingly, studies have shown that contaminants like zinc, selenium, lead, and cadmium can leach out of aging turf and infill and into runoff as well. This means a fake lawn might quietly be introducing heavy metals into your soil or local water over time. In Palm Beach County, such micro-pollution could eventually reach canals and wetlands, affecting wildlife.
Speaking of wildlife, artificial turf creates a literal dead zone for ecosystems. A natural lawn, while sometimes derided for low biodiversity, still supports insects, earthworms, birds, and microorganisms in the soil. Living turf provides food and habitat – beetles and bees in the grass, earthworms aerating soil, birds feeding on the bugs, etc. By contrast, plastic grass offers nothing for wildlife. It blocks access to soil for burrowing creatures and prevents any natural plant growth. Florida Master Gardeners emphasize that healthy lawns contribute to local ecosystems, whereas artificial ones do not support insects or soil life at all. Over time, the ground beneath turf can become severely compacted and devoid of organic matter, essentially sterile once the fake carpet is laid. This concern was raised in Boynton Beach, FL, where city commissioners noted synthetic turf’s “inability to support local ecosystems” and potential to harm biodiversity if overused in landscapes. In a state proud of its wildlife – from backyard birds to pollinators – replacing green space with plastic can quietly chip away at urban ecology.
Artificial turf also contributes to plastic pollution and waste on a significant scale. The turf blades and backing gradually degrade, shedding microplastics into the environment. Every time it rains or the turf is washed, small synthetic fibers and particles can wash into drains or soil, adding to the growing microplastic load in waterways. Then there’s the issue of disposal: most artificial turf has a lifespan of about 8 to 15 years before it wears out or fades. Unlike grass clippings which biodegrade into fertilizer, old turf is essentially 100% plastic waste. Currently, there is no widespread method to recycle worn-out turf, so “retired” turf carpets (and the tons of infill embedded in them) must be disposed of in landfills or by incineration. One typical athletic field contains 40,000 pounds of plastic carpet and 400,000 pounds of infill (often tire rubber or sand) – imagine dozens of such fields being replaced each year and you get a sense of the waste volume. The carbon footprint is hefty as well: manufacturing plastic turf is fossil-fuel intensive, and some turf (especially those with rubber infill) can even emit methane, a potent greenhouse gas, as they heat up and off-gas.
Finally, consider the maintenance paradox: artificial turf is often sold as “low maintenance,” but keeping it usable has its own environmental costs. In Florida’s climate, turf needs regular rinsing or washing (weekly, in many cases) to cool it down and clean off dust, sweat, and pet waste. Manufacturers recommend hosing down turf fields to reduce surface temperatures (essentially using water because the fake grass can’t cool itself). They also suggest applying antimicrobial chemicals to sanitize areas with pet or bird droppings. All that water use and chemical cleaner runoff can negate some of the water savings from not irrigating grass. In essence, artificial turf can trade one set of environmental impacts (watering, mowing) for another (plastic pollution, runoff, heat, and waste). This trade-off has led many communities to think twice. The Florida-Friendly Landscaping™ program explicitly notes that artificial turf runs counter to its sustainability goals due to these issues. In Palm Beach County, West Palm Beach has even prohibited synthetic turf in front yards for aesthetic and drainage reasons, enforcing fines on violators. And as of 2025, Florida’s legislature is requiring the state DEP to develop standards for synthetic turf installations (to address some of these concerns) – while also curbing local governments from outright banning turf if those standards are met. This push-pull reflects a growing recognition: the environmental downsides of artificial turf are very real, especially in a state with fragile ecosystems and intense weather patterns.
Safety and Injury Concerns: Heat Stress, Burns, and Physical Injuries
Beyond chemistry and ecology, artificial turf poses tangible safety risks to people – from children on playgrounds to professional athletes. Heat retention is one major safety hazard. As noted, the surface of artificial turf can become extremely hot under the sun. For a child or pet playing on a superheated fake lawn, burns are a real danger. Medical experts warn that skin contact with surfaces over 120°F can cause first-degree burns in minutes and 130°F+ can cause second-degree burns. Unshaded playground turf or rubber flooring on a 90°F Florida day can easily exceed those temperatures – in fact, monitoring in some playgrounds has found the air just above artificial surfaces to be 50–60°F hotter than above natural ground. Young children are especially vulnerable, as their skin is thinner and they may not realize the ground is burning hot until it’s too late. Cases of kids getting foot blisters or burns from playground turf or rubberized surfaces have been documented, prompting some parents to push for warning signs on such play areas in summer. Heat exhaustion is another threat – playing sports on a hot turf field puts athletes at higher risk of dehydration and heat stroke. Unlike grass, which has a cooling effect and can be wet down to provide some evaporative cooling, artificial fields can act like radiators, raising body temperatures quickly. Coaches in Florida have learned to schedule extra water breaks or avoid midday practices on turf. Some fields are even watered briefly during games solely to cool the surface (a temporary fix at best). The Safe Healthy Playing Fields coalition bluntly states: “Synthetic turf can get so hot it can melt cleats, blister hands and feet, and induce heatstroke”. In other words, the heat hazard isn’t just theoretical – it’s directly linked to player safety.
Another safety aspect is the physical abrasiveness and hardness of turf. Athletes often talk about “turf burn,” the nasty scrapes one gets when skidding on artificial turf. The plastic fibers and underlying sand/rubber infill can cause painful abrasions, more severe than grass would, sometimes leaving open wounds that can get infected. Some studies have noted higher incidents of certain skin infections (like MRSA staph infections) in teams that play on artificial turf, possibly because of these frequent abrasions combined with bacteria surviving in the synthetic material. Additionally, artificial turf generally provides less cushioning than well-kept natural grass, especially as it ages. Impact injuries – like concussions from a head hitting the ground – are a concern if the turf padding/infill is insufficient or uneven. Sports surface experts measure hardness via the “Gmax” or Clegg impact test; if a turf field isn’t properly maintained, it can become unacceptably hard, akin to landing on thin carpet over concrete.
However, the most hotly debated safety issue has been whether playing on artificial turf leads to more injuries than natural grass. Many athletes insist it does, and recent data backs them up. Professional football has been a bellwether: The NFL Players Association analyzed years of injury statistics and found significantly higher rates of certain injuries on artificial fields. According to the NFLPA President J.C. Tretter, players have about 28% higher rate of non-contact lower extremity injuries on turf compared to grass, including a 32% higher rate of non-contact knee injuries and a whopping 69% higher rate of non-contact foot and ankle injuries on turf. These figures, spanning 2012–2018 seasons, reinforce what players anecdotally felt – that the “give” in natural soil and sod can reduce injury severity, whereas the stiffer artificial surface transfers more force to joints. For example, when a player’s cleat sticks in real grass, the grass and roots tear somewhat (a natural release); on turf, the cleat can stick too well, causing the player’s knee or ankle to twist beyond its limit. This injury trend isn’t limited to the NFL. Some studies of soccer, rugby, and youth sports have similarly found elevated injury rates or different injury patterns on turf, particularly for knee and ankle sprains. While turf technology has improved over the decades, the consensus of many athletes and trainers is that nothing beats real grass for player safety. This sentiment has reached local communities too. For instance, several Florida high schools and parks have reconsidered planned turf installations after public outcry about safety and health issues, opting to improve natural grass fields instead. And as mentioned earlier, the NFLPA and even some coaches are calling for a return to grass in all pro stadiums on safety grounds.
It’s worth noting that artificial turf can also pose unique safety challenges in community settings. Pet owners find that fake grass, when soiled with pet waste, needs diligent cleaning; otherwise bacteria can linger, since there’s no soil microbes or rain percolation to naturally break down feces or urine. This is why antimicrobial sprays are recommended – but those chemicals create their own exposure risks for kids and animals. Additionally, weeds can surprisingly become a problem on turf over time (seeds can settle in the infill), meaning homeowners or parks might resort to herbicide sprays to keep a “perfect” plastic lawn. This adds another chemical into the environment and potential contact with people. All these factors illustrate that the safety profile of artificial turf is more complex than its marketing suggests. What looks like a smooth green play area can hide scorching heat, abrasive surfaces, and subtle injury risks that stakeholders from HOAs to city councils are increasingly weighing. As Boynton Beach’s mayor pointed out in a 2024 meeting on artificial turf, further research and expert input were needed to ensure any use of turf complies with evolving safety and environmental regulations. In Palm Beach County and beyond, that caution is well warranted.
Removing Artificial Turf and Returning to Natural Grass
Given the array of concerns, some homeowners and facility managers are now looking to remove existing artificial turf and go back to natural sod. Reverting to real grass can restore some of the environmental benefits and peace of mind – but the transition requires careful steps. Removing artificial turf is a labor-intensive process that involves more than just pulling up a carpet. Here’s how experts recommend approaching it:
Full Removal of Turf and Infill
Artificial turf is usually installed in layers: plastic grass blades stitched to a backing, infill materials (like crumb rubber or sand) spread in between to stabilize it, plus binding tape at seams and spikes or nails at the edges. All of these components need to be pulled up and removed. Start by cutting the turf carpet into manageable strips or squares (it’s heavy and often held down tightly). Crews will peel back and cut the turf, then gather the infill that falls out, along with any underlayment, tape, and anchoring pins. It’s important to collect as much of the infill rubber or sand as possible; leaving a lot in the soil could hinder new grass growth and pose ongoing pollution. Dispose of the old turf responsibly – check if any recycling program exists (they are rare, but emerging in some areas), otherwise it will have to go to a landfill. Prepare for large volumes: a 500 sq. ft. front lawn’s turf can weigh a few thousand pounds when rolled up with infill.
Soil Rehabilitation
Once the fake lawn is gone, you’ll likely find the soil underneath is compacted and may be of poor quality (often a gravel base was laid for drainage). Natural grass won’t thrive in compacted, inert soil, so you must rehabilitate the ground. This can involve rototilling to loosen the subsoil and adding fresh topsoil or compost to create a fertile growing layer. Many turf-removal projects in Florida find they need to bring in several inches of good soil, because the original topsoil might have been stripped or contaminated. At this stage, consider testing the soil pH and nutrients – Florida soils can be sandy and acidic, so you might mix in lime or organic matter as needed to suit the sod you’ll plant. Ensuring proper grading for drainage is also key (you don’t want water pooling on your new lawn). This prep work can be the difference between a patchy new lawn and a lush one.
Installing Natural Sod (or Seed)
With healthy soil in place, you can lay down natural turfgrass. Sod installation is the quickest route – rolls or squares of mature grass (with soil and roots) are placed to instantly cover the area. Choose a grass type suited to your region and yard conditions. In South Florida, popular choices are St. Augustine grass (e.g. Floratam variety for sunny areas, or Palmetto or CitraBlue for more shade tolerance) and zoysia or Bermuda grass for high-traffic or sports-heavy yards. These varieties are bred for Florida’s climate – St. Augustine handles heat and occasional drought well, while zoysia and Bermuda create dense, resilient lawns for active use. Make sure you or your installer water the new sod thoroughly upon installation to help it root in. If you prefer to seed or patch the lawn (more common for large fields or budget projects), be prepared for a longer establishment period and protect the area from erosion in the meantime.
Irrigation and Maintenance
Remember that real grass does require routine care – but with modern irrigation systems and Florida-friendly landscaping practices, it can be manageable and environmentally sound. You’ll want to ensure an irrigation system is in place or hoses are set up, because new sod must be kept moist daily for the first couple of weeks. Plan to water in the early mornings as per local watering restrictions and to reduce evaporation. Long-term, set irrigation controllers to avoid overwatering. Mowing and feeding the lawn will also be back on your to-do list, but you can minimize chemical use by choosing slow-release, organic fertilizers and mowing high to encourage deep roots (which makes the grass more drought-tolerant). Integrated pest management can handle most pest or weed issues without heavy herbicides. In short, a well-maintained natural lawn can stay healthy with moderate effort – and offers real perks like cooling the yard, absorbing runoff, and even adding oxygen to the air.
Considering Alternatives
If you removed your turf because maintaining a traditional lawn was too difficult in that spot, consider whether you really need grass everywhere. Florida-friendly landscaping emphasizes “right plant, right place.” In some cases, groundcover plants or native landscaping might be a smart alternative to re-sodding. For instance, instead of replanting turf in a perpetually shady or dry area, you could install a groundcover like Asiatic jasmine or perennial peanut that forms a green carpet with minimal mowing or watering. Or expand mulched beds with native shrubs and flowers, creating a low-maintenance garden that supports pollinators. The University of Florida IFAS extension suggests groundcovers as an appropriate alternative if you’re tempted by artificial turf due to lawn trouble. You’ll save on mowing and still avoid the pitfalls of plastic turf. Hardscaping is another option – some homeowners replace problem lawn sections with pavers, decorative gravel, or patios (just keep drainage in mind to offset impervious surfaces). The goal is to achieve a landscape that meets your needs (play, pets, aesthetics) while aligning with Florida’s environment.
Removing artificial turf isn’t a trivial project – it can be disruptive and somewhat costly (Florida landscapers estimate roughly $2.50–$5 per square foot for removal and another few hundred dollars for each pallet of sod installed, depending on the grass type). But many who have done it say the effort is worth it for the cooler, safer, and more natural yard they regain. By switching back to real grass or eco-friendly landscaping, you’ll be restoring a little piece of the ecosystem – and possibly your peace of mind, knowing your lawn isn’t leaching hidden toxins or harboring extreme heat.
Artificial turf comes with a host of underappreciated risks. What began as a maintenance shortcut can introduce health hazards from chemicals, degrade the environment with heat and plastic pollution, and pose safety issues that natural grass avoids. Homeowners, HOAs, and city boards in Florida and around the country are increasingly weighing these drawbacks against the supposed convenience. The evidence suggests that caution (and perhaps a return to natural greenery) is prudent. After all, there’s a reason real grass has blanketed our yards and parks for centuries – it works in harmony with nature and people in ways that plastic can’t easily replicate. Before rolling out the green carpet, it’s wise to dig deeper into the science and long-term implications. And if you already have an artificial lawn that’s causing second thoughts, know that there is a path back to a safer, cooler, and living landscape. The grass may indeed be greener on the other side – when it’s real.
