Environmental activists and residents from around Pennsylvania staged a speakout Sunday at a Residual and Biosolids conference, calling for the expanded testing of Synagro sewer sludge, and for public reporting on its toxicity and disposal from the Carlyle Group, Synagro's private equity owner. "Community members don't know everything that is in the sludge dumped nearby," said Sue Fox of the Shrewsbury Township Environmental Protection Community (STEPCO) "Without more information, I worry about possible health effects and diminished quality of life. Until there is more scientific data and more testing that inspires real confidence, I think sewage sludge land application should be ceased. Sludge testing by the sewage treatment plants seems to me like the fox watching the chicken house."
