Turf Wars: test for hazardous materials in synthetic turf
THIS summer three women from Westport, Conn., urged a nonprofit group in North Haven to test for hazardous materials in synthetic turf that is being placed on playing fields across their state.
The results came back positive, showing that hazardous metals in the turf granules leach into water, and that at 140 degrees Fahrenheit (a temperature that synthetic turf can reach during summer), other toxic chemicals are released into the air.
Like the women in Westport, a number of residents in several New Jersey towns want local officials to call off synthetic turf installations.
