NORTH CAROLINA STATE HEALTH STUDY OF SLUDGE/BIOSOLIDS IGNORED
North Carolina politians and environmental regulator ignore Health Department Study recommendations which indicate
permitted sludge/biosolids use puts farm families and neighbors at risk from airborne cancer causing agents and
disease causing agents.
Letter from Douglas S. Campbell, MD. MPH, Head, Occupational & Environmental Epidemiology Branch of DHHS
to DENR requesting that scientific recommendations be incorporated in land application sludge/biosolids permits. to
protect environment and hunam health. DENR has ignored the recommendations since 2005.

How can any land application sludge/biosolids disposal site be safe?
1989 EPA document confirms that Arsenic, Beryllium, Cadmium, Chromium VI, and Nickel are cancer causing agents
when inhaled in dust from permitted sludge/biosolids disposal.sites.
Then we have to consider that Toxic Organic sludge Dust is Not Good for You, Deaths doubled in 15 years
Even as EPA concludes in Part 503.9(t), we can be assured that Sewage sludge (Biosolids) is a potential killer.
