At sometime in the future EPA will look at chemicals and pathogens for which it has little or no data.
In a paper found in the Journal of Environmental Quality (2005), Interpreting Science in the Real World for
Sustainable Land Application
, EPA Senior Sludge Scientist, Robert Bastian, states, "The major objectives of this
paper are to (i) review how current land application practices, and our understanding of them, have evolved over time
and (ii) explore how science is used (and sometimes misused or ignored) in the development of design, regulation, and
management of sustainable land application.
Land treatment technologies have been used effectively for the
treatment and recycling of many types of wastewaters and organic residuals for many years."

Bastian admits, "Concerns raised over emerging pathogens and chemicals for which little or no data are
available tend to be put off for future consideration when more adequate data are generated."

In a presentation, National Update and Trends in Biosolids Management in the U.S.,December 7, 2005,
Robert K. Bastian (EPA) notes there will be:

"Less active EPA oversight, but continued program support,"
Increase the resources devoted to EPA's biosolids program,
Addressing areas of growing interest, (e.g., Odors, Dioxins, Radiation, Bioaerosols, Bioassay),
