Re: E-M:/ sludge



Folks,
 
So called "beneficial reuse" of sewage sludges has developed a large and dedicated following amoung POTW operators and regulatory agencies.  Its hard to find many voices against it.  A recent survey by Wisconsin DNR of POTW sludges found PCBs in a significant portion (levels available upon request).  Could Michigan POTWs have the same problem? 

The overapplication and nutrient issues is also clearly important.

Respectfully submitted,
I think it's important to note that even uncontaminated sludge poses
threats to the natural environment when over-applied, as it often is,
because excess nutrient runoff chokes local streams and rivers. This
phenomenon is particularly visible in the case of CAFO lagoon failure, as
happened with the New River in Virginia.
