On November 6, 2015, Dr. Homero Harari, TCEEE member, joined U.S. Senator Richard Blumenthal and Nancy Alderman of Environment and Health Inc. to advocate for further investigation into potentially harmful chemicals and carcinogens in crumb rubber filling found in turf fields and playgrounds. Senator Blumenthal wrote a letter to the U.S. Consumer Product Safety Commission calling for a federal study of crumb rubber to assess potential health threats, and Dr. Harari spoke in support of his proposal at the press event.
