During the April 21st Board of Health meeting, a significant discussion took place regarding the environmental and public health risks associated with artificial turf. Experts Sarah Evans and Susan Chapnick presented evidence concerning the presence of PFAS, heavy metals, and microplastics in these surfaces, as well as the risks of extreme heat retention.

Of particular concern was the impact on children. Experts noted that because children have higher respiratory rates and less ability to regulate body temperature, they are more susceptible to these environmental exposures. The Board has since tasked staff with researching other municipalities that have implemented artificial turf bans or strict policies to see how Lexington might protect its residents.

Additionally, the Board addressed the rise of Alpha-gal syndrome (a red meat allergy linked to tick bites). While there is a need to control pests, Board members expressed serious concerns about the effectiveness and environmental damage caused by residential chemical sprays. The Board is currently seeking more information from state agencies regarding the risks of these chemical treatments.

As these issues involve both public safety and how municipal funds are spent on landscaping and pest control, we will continue to monitor the Board's follow-up actions.

“Children are not little adults; they are more susceptible to environmental exposures due to proximity to the ground, higher respiratory rates, and less ability to regulate body temperature.”

— Sarah Evans · Discussing why artificial turf hazards are particularly concerning for pediatric health. 19:01

“The most important measurement for environmental impact is not what is in the material, but what is in the leachate (what washes off the field).”

— Susan Chapnick · Addressing concerns about the efficacy of measuring contaminants within the turf itself versus environmental runoff. 47:24

“There really aren't good studies of playgrounds specifically [regarding chemical exposure], but... there are reasons to believe based on what we know those products are made of and the ways that children behave... that they could be exposed to harmful chemicals.”

— Unidentified speaker · Responding to a question about leachate and health hazards in playground surfaces. 1:24:02

“We definitely need better data collection... in a format that is queryable, and that we, the Board of Health, can actually look at those data and follow them over time.”

— Wendy Heiger-Bernays · Discussing the implementation of heat-related play policies and the necessity of documented metrics. 1:08:34

“I'm very concerned about that. This notion that you're going to be able to use a chemical to spray your property... and be effective without creating, honestly, havoc in the environment, I find to be problematic.”

— Wendy Heiger-Bernays · Discussing advertisements for chemical spraying to combat Alpha-gal syndrome/ticks. 1:41:00

Controversy & ⁠dissent

Where the board, the community, or the agenda diverged.

Potentially controversial issues

01

Artificial Turf Environmental and Public Health Risks

The topic involves potential chemical exposure (PFAS, heavy metals) and physical hazards (heat retention) for children. While no immediate vote was taken, the expert testimony highlights a significant conflict between the utility of artificial turf and public health safety, which often impacts municipal spending and school/park management.
Board position: The board expressed significant concern, with members calling for better data collection and investigation into community policies/bans.
medium concern

Chemical Pest Control for Alpha-gal Syndrome

There is a tension between the need to control ticks (which cause red meat allergies) and the environmental 'havoc' caused by chemical sprays. Board members expressed skepticism regarding the efficacy and safety of residential chemical treatments.
Board position: Skeptical/Cautionary; the Board requested further information from state agencies regarding the risks of these sprays.
medium concern

What are the actual health risks of the artificial turf in our parks and schools? During the 4/21 Board of Health meeting, experts laid out a concerning picture for Lexington residents. 🧵 #MeetingWatch #LexingtonMA

Experts presented evidence that artificial turf can expose children to PFAS, heavy metals, and microplastics. Because children have higher respiratory rates and can't regulate temperature as well, they are at higher risk for chemical and heat-related exposure.

The Board isn't just listening—they are pushing for action. They've requested a list of other communities that have implemented turf bans and are calling for better, queryable data to track heat-related play risks in our town.

This matters. As the town manages public spaces and school budgets, the intersection of environmental safety and fiscal responsibility must be front and center. Stay tuned as the Board follows up on these findings. https://meetingwatch.org/ma/lexington/board-of-health/2026-04-21/
