EPA has acknowledged 25 families of Infectious pathogens in sludge. While EPA does not 
define the nature of a pathogen, the Department of Transportation does.
These are very dangerous in a laboratory setting and most be handled at a Biohazard 2 level. 
These are only a few of the potential pathogens in sludge that Canada has created MSDS 
Laboratory Sheets on.
EPA is not concerned about the toxic metals listed in part 503 because the health effects are 
not evident as quickly and it is harder to prove a connection.

"AGRICULTURAL AND RURAL AFFAIRS RESOLUTIONS - Resolution in Support of Increased 
Regulation of Land Spreading of Bio-Solid Residuals or Sludge:
Issue: Support of increased regulation of the land spreading of bio-solid residuals or sludge.
Adopted Policy: In the absence of effective local and state regulations, which implement a viable 
bio-solids management program in place, NACo urges Congress to support increased regulation of the 
land spreading of bio-solid residuals or sludge and further urges Congress to appropriate sufficient funds 
so as to not create an unfunded mandate on local governments.
Background: Counties across the nation are facing challenges from unregulated dumping of bio-solid/waste 
water residue, commonly known as sludge. Often this dumping has a negative impact on municipal water 
systems and recreational water outlets.
Since sludge must be dealt with, many municipal sewers have long-term contracts with sludge haulers to 
take their sludge. As a result, sludge haulers have contracts with large agribusinesses to take and spread 
their sludge as fertilizer.
Many states have not put sufficient resources into regulating the enforcement (of) sludge dumping. Lack 
of enforcement of the most noxious class of sludge (B) by states can cause air and water contamination. 
Counties have made an effort to regulate the class B sludge; however enforcement of such ordinances can 
be difficult and require litigation.
If federal and/or state law mandated all sewers to treat all sewage to the Class AA standard, which is 
possible, there would be no noxious objection to its spreading.
Fiscal/Urban/Rural Impact: Since rural areas are far more likely to be the recipients of Class B sludge, 
many rural counties face difficult challenges with dealing with sludge.
