Biosolids Emissions Assessment Model (BEAM) - NEBRA was a member of the team, led by Sylvis, that produced this model and spreadsheet calculator for estimating greenhouse gas emissions from biosolids management for the Canadian Council of Ministers of the Environment. NOW updated! Version 1.1 available free here.
The White House garden & biosolids compost - This story began in spring of 2009: a single soil test at the exciting new home garden at the White House triggered an online and print discussion of lead in urban soils and its potential impacts. Without fact-checking, many of the writers who took the story "viral" on the internet have assumed that biosolids compost helped cause the somewhat elevated lead level. That's unlikely, as this Information Update demonstrates. The fact is, biosolids compost is a high-demand product used widely in agriculture, horticulture, and turf care. It is even used to reduce lead bioavailability at significantly contaminated sites. Published guides and research papers on this topic are available; contact the NEBRA office.

NEBRA Response to the Film "Sludge Diet" ("Tabou(e)") This documentary, originally released in 2006 in French in Quebec, advocates against the use of biosolids on land by citing incidents that purportedly show harm from this practice. The conclusions reached by those in the film have been refuted by U. S. EPA, state environmental agencies, and others, as discussed in this NEBRA response. Download here.
A National Biosolids Regulation, Quality, End Use & Disposal Survey (2007) provides the most comprehensive information to date regarding how sewage sludge is managed in the United States. Data is from 2004. The report consists of four parts:

Video: Vermont Biosolids Forum
November 5, 2013 • Waterbury, VT
This forum was convened by the Vermont Dept. of Environmental Conservation (DEC). It included ~80 stakeholders involved in biosolids management throughout the state, including farmers, solid waste managers, wastewater treatment facility personnel, biosolids management companies, and NEBRA - all of whom spoke in support of recycling biosolids to soils in accordance with current regulations. These presentations provide excellent testimony on the benefits and safety of using modern biosolids as soil amendments and fertilizers. Two attendees spoke against the practice. At the forum, DEC announced its plan to begin the process of updating the state's biosolids management regulations.
