The 11th Annual Soil and Water Science Research Forum
The 11th Annual Soil and Water Science Research Forum is scheduled for September
10, 2010, in Gainesville, Florida. The forum is designed to bring together
representatives from state and federal agencies as well as private industry, faculty,
graduate students, and prospective students interested in soil and water science.
The forum will provide an opportunity for all those interested in soil and water
science to interact with our students, faculty, and administrators on campus. This
year theme for the forum is on “Soil, Water Contamination and Public Health” ,
which is one of the thrust areas of the department. This year, Dr. Ian L. Pepper,
Professor and Director, Environmental Research Laboratory, Soil, Water, and
Environmental Sciences Department, University of Arizona, is the featured keynote
speaker at the forum. We look forward to your participation in the forum. If you
are planning to attend, please register at http://soils.ifas.ufl.edu/forum/.
For additional information, contact James Jawitz at Jawitz@ufl.edu.

Domestic Wastewater Residuals
http://www.dep.state.fl.us/water/wastewater/dom/reshome.htm
When domestic wastewater is treated, a solid material accumulates in the wastewater treatment plant and must be removed periodically to keep the plant operating properly. The collected material, called “residuals,” “biosolids,” or more commonly “sewage sludge,” is high in organic content, and contains moderate amounts of nutrients that are needed by plants. These characteristics make residuals valuable as a soil conditioner and fertilizer.
Properly treated residuals may be used as a fertilizer supplement or soil amendment, subject to regulatory requirements that have been established to protect public health and the environment. These requirements (found in Chapter 62-640, F.A.C.) include pollutant limits, treatment to destroy harmful microorganisms, and management practices for land application sites. Residuals may be used by application to land in farming and ranching operations, forest lands, and public areas such as parks, or in land reclamation projects such as restoration of mining properties. The highest quality of residuals, known in Florida as “Class AA,” are distributed and marketed like other commercial fertilizers.

The Department is currently considering revisions to Chapter 62-640, F.A.C. To find out more about the rulemaking effort, see the Domestic Wastewater Residuals Rulemaking Updates page. Next hearing May 20th, 2010
Residuals-Related Information and Downloads
This fact sheet provides an overview of residuals and other information of interest to farmers or ranchers who beneficially use, or who are considering beneficially using domestic wastewater residuals.
This reports contains information on companies, quantities and other information regarding the distribution and marketing of class AA residuals products in Florida.
This downloadable Excel file can be used by permittees to perform basic residuals calculations such as converting from gallons to dry tons. This can aid the permittees in record keeping as well as determining results to enter onto report forms. This software is only meant as an aid and does not relieve the permittee from reporting accurate information on Department reporting forms.
As part of the FWEA Biosolids Outreach Committee, Dr. Phil Kane (DEP-Orlando District Office) developed a biosolids infusion unit to be used as a multidisciplinary educator’s guide for teaching students about biosolids issues. This guide book includes several skills-training courses to expose middle school students to “real-life” simulations such as environmental rule making, town meetings, and exploration of the beneficial use of biosolids as a fertilizer.
