Biosolids by the Book

摘要

Due to the importance of certification in the wastewater industry, several nongovernmental organizations have taken the lead in developing their own voluntary certification programs in the areas of wastewater collection and laboratory analysis.rnBut until recently, in most states, one area of expertise related to wastewater treatment - biosolids land application - has not had the benefit of its own certification program. Now, the Association of Boards of Certification (ABC; Ames, Iowa) has stepped in to help fill the void with its nationally validated voluntary biosolids land-applier certification program.
