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
--1980/1995
Even as EPA concludes in Part 503.9(t), we can be assured that Sewage sludge (Biosolids) is a potential killer.
