GROUP OF CORNELL UNIVERSITY RESEARCHERS, in a letter to SLUDGE last week, joined the 
growing list of vocal opponents to the controversial views of Cornell toxicologist 
Donald Lisk, who claims that sludges of all types are for the most part too toxic 
for any form of land application (SLUDGE, Oct. 28, 1981, p. 169). "We are concerned," 
wrote William Jewell, Lewis Naylor, Raymond Loehr and Richard Dick, "because we do 
mot share the opinion expressed (by Lisk) and feel that the position is largely un- 
justified... Cornell University has no policy on recommended sludge disposal practices 
and has nver recommended incineration as the safest method of sludge disposal." 
The four researchers agree, in general, with the position established in the policy 
and guidance package addressing application of sludge to cropland developed by EPA, 
Department of Agriculture and the Food and Drug Administration (SLUDGE, Jan. 22, 1981, 
p- 10). "We further feel," they wrote, "that the land application of sludges can 
represent the most cost-effective means available for controlling this kind of pollu- 
tion in many locaticns. We feel that the e-owing base of svecific informacion sup—- 
ports the controlled use of lend application of sludge as a management alernative."
