A large number of chemicals are found in tire crumb. Many of these have adverse effects on human health or the environment. Some of the chemicals found in tire crumb are endocrine disrupters (e.g., phthalate esters); some are known or suspected carcinogens (e.g., arsenic, cadmium, benzene, styrene); and some are associated with other human health effects.
Children are uniquely vulnerable to the effects of toxic chemicals because their organ systems are developing rapidly and their detoxification mechanisms are immature, among other factors. For these reasons, it is particularly important to make careful choices about children’s exposures. For more details:
- See the “Tire Crumb” section (page 4) of the TURI report “Athletic Playing Fields: Choosing Safer Options for Health and Environment.”
- See TURI’s detailed document on tire crumb.

While vendors do offer alternative infills, many of these materials have not been studied fully. Other infills on the market may be made with rubber, plastic, mineral-based, or plant-derived materials. When researching turf options, communities should evaluate materials carefully and may wish to require additional testing to ensure they have considered the full range of chemicals.
See pages 5 through 9 of the turf report for a thorough description of a number of alternative infills.
Use of artificial turf present a number of issues other than human health concerns related to chemicals hazards. Refer to pages 11 through 13 of the turf report and the Physical Hazards document for more details on the concerns described below.
Heat: In sunny, warm weather, artificial turf can become much hotter than natural grass, raising concerns related to heat stress for athletes playing on the fields.
Environmental concerns: Environmental concerns include loss of wildlife habitat and contaminated runoff into the environment. Another environmental concern is migration of the synthetic particles, including infill and plastic grass blades, into the surrounding environment.
Disposal: Some synthetic materials may be reusable one or more times, while others may have to be disposed of in a landfill or through incineration when the field is due for replacement.
Injuries: One particular concern is increased rates of turf burns (skin abrasions) associated with playing on artificial turf. These abrasions are a risk factor for serious bacterial infections.
By using organic grass, communities eliminate the use of toxic insecticides, herbicides and fungicides. Organically maintained grass will also eliminate many of the health concerns found in artificial turf.
Refer to page 16 of the “Athletic Playing Fields: Choosing Safer Options for Health and Environment.” Communities such as Springfield, Marblehead and Martha’s Vineyard, all in Massachusetts, have improved their field quality through organic management of their athletic fields.

Many parents, athletic directors and town administrators have contacted us with this question. According to organic grass athletic field experts, the key to a well-functioning field is healthy soil and a healthy grass root system. Individual fields can be diagnosed and maintained in a way that addresses specific issues and performance needs.
Take a look at the Springfield case study to find the number of hours played at three organically managed grass fields. If you want to estimate the number of playable hours on a soccer field in your community, you can use Treetop Park, the full-sized soccer field, as an example. Treetop Park is used for approximately 1,050 hours of practice, games, and informal activity annually.
We’ve also documented playing time on fields in the Marblehead case study. The town has maintained high quality, organically managed grass fields for more than 15 years. In the case study, you’ll find hours of use per week for four town fields, which are used for field hockey, baseball, lacrosse, soccer and more.
If you want to estimate the number of playable hours on a football field in your community, you can use Hopkins Field, the full-sized football field, as an example. This field was used for multiple sports and recreational activities for a total of 1,860 hours in 2018.
No. Springfield and Marblehead do not rest their fields and do not restrict play during particular seasons or rotate fields. When drainage is designed appropriately and soil is properly aerated and maintained, the soil is able to hold more rainwater, reducing puddling after rain.
Springfield does not cancel field use for rain. Marblehead does have a “red flag” policy for times when the ground is saturated with rainwater after a full day of hard rain. Field puddling can be an issue on the clay used on softball and baseball infields. This issue is independent of grass or artificial turf used in the outfields.
Many communities have questions about costs associated with annual maintenance of organically managed fields. See our case studies to review real annual maintenance cost figures for organically maintained fields in Springfield and Marblehead in 2018. When the full product life cycle is taken into account, natural grass is likely to be more cost effective than artificial turf. Organic management of natural grass builds healthy soil and a robust root system, which can further lower costs over time.

For personalized help with grass field issues, or converting a field to organic management, consultants can be a helpful resource. Below are a few that specialize in organic athletic fields and work in Massachusetts. Note that TURI does not endorse any specific provider.
Several Massachusetts communities have made decisions about athletic field surfacing based on wellhead zoning. They were able to receive guidance from regional MassDEP representatives. For up to date information, contact MassDEP. For information on Zone 1 wellhead protection zones, visit DEP's website.
Yes, we do. We have researched a number of playground surfacing options on the market, including those made with tire crumb. Download our Playground Surfacing report.
