Sewage Sludge in the News
Updated on Thursday, January 26, to add a late-breaking research article:
- “Measurement of Flame Retardants and Triclosan in Municipal Sewage Sludge and Biosolids” (Environment International, April 2012 volume): “The biosolids [from California and North Carolina] and SRM 2781 were analyzed for PBDEs, hexabromobenzene (HBB), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), 2-ethylhexyl 2,3,4,5-tetrabromobenzoate (TBB), di(2-ethylhexyl)-2,3,4,5-tetrabromophthalate (TBPH), the chlorinated flame retardant Dechlorane Plus (syn- and anti-isomers), and the antimicrobial agent 5-chloro-2-(2,4-dichlorophenoxy)phenol (triclosan). PBDEs were detected in every sample analyzed, and ΣPBDE concentrations ranged from 1750 to 6358 ng/g dry weight. Additionally, the PBDE replacement chemicals TBB and TBPH were detected at concentrations ranging from 120 to 3749 ng/g dry weight and from 206 to 1631 ng/g dry weight, respectively. Triclosan concentrations ranged from 490 to 13,866 ng/g dry weight. The detection of these contaminants of emerging concern in biosolids suggests that these chemicals have the potential to migrate out of consumer products and enter the outdoor environment” (from article abstract, with emphasis added).

- Pennsylvania Compost Program Stench Causes Outcry: According to the MarpleNewtown Patch (1/24) and HaverfordHavertown Patch (1/20), the program composts local leaves, but the unholy stench has neighbors upset enough to demand the program be ended. The two neighboring townships, Havertown and Marple, Pennsylvania, hired well-known sewage sludge consultant Craig Coker, to help reduce the odor. Coker is on the Board of the sludge front group the U.S. Composting Council and a former member of the sludge industry trade group the Water Environment Federation‘s (WEF’s) “Biosolids” Management Committee and, in 2008, wrote an editorial (or “advertorial,” in PR jargon) for the Roanoke Times in which he advocated the safety of treated, minimally regulated sewage sludge as fertilizer. Are the townships “composting” human and industrial waste sludge with their leaves? (more…)
