Arocha Percentage of work completed in this period (%): 40% Accumulative Percentage of work completed (%): 65% Completion Date: February 28th, 2006 Project status: Schedule ___ Suspended _X__ Delayed ___ Cancelled ___ Completed Activities progress: (according to work schedule submitted with application) Estimated Dependant Activity started Completed Completed on task(s) completion Summary of Progress on Project this Quarter: The progress can be summarized as follows
New tests on the chemical stability of crumb rubber as a function of particle size and pHs
were completed. Preliminary results suggested that crumb rubber will not pollute aqueous solutions with inorganics or organic species.
Verification of the reproducibility of the sorption tests with Xylene Completion of the sorption tests with Toluene. Completion of sorption tests with Etilbencene. Continuation of sorption tests with Tetracycline at different pHs. Preliminary results suggest
the sorption of tetracycline although there are still some problems related to the reproducibility of the results due to the high concentrations of tetracycline solutions.
A new undergraduate student, from Civil Engineering will join the research group starting in
The first drafts on sorption of inorganics (F. Calisir, O. Perales) and organic solvents (L.
Alamo, F. Roman) are being completed with more recent data.
Presentation at the Senior-ACS Conference, November, 2005, La Parguera, Puerto Rico Presentation at the last AIDIS Conference, September 30th 2005, Isla Verde, Puerto Rico). The Interamerican Society of Sanitary Engineering and Environmental Sciences (AIDIS)
awarded the First Prize on Research to the work: “Remoción de BTEX por Partículas de Goma Recicladas en Soluciones Acuosas”, presented by UPRM-PRWRERI last September 2005.
Recently, the Waste Management Authority (ADS) awarded $140,000 for the acquisition of
major instrumental equipment. The grant is for instrumentation only. The instrumentation to be purchased will allow us to analyze concentration at the parts per billion (ppb) levels, as required for studies on mercury and arsenic (these two species are addressed in the present proposal as a complement to our studies on heavy metals).
Problems encountered and/or assistance need:
Although the HPLC/GC-MS methods for tetracycline were standardized, it works only for
highly concentrated solutions (above 50ppm).
In order to be able to evaluate the sorption behavior at more dilute tetracycline
concentrations (<10ppm) a direct measurement by GC-MS must be considered. The corresponding adaptations for these direct analyses are being attempted.
Certifications: As the Principal Investigator, I certify that the information contained within this quarterly report accurately reflects the status of this project.

American Appellations of Origin In December, 2008 the California Association of Winegrape Growers, New York Wine Grape Growers Association, Oregon Winegrowers Association and Washington Association of Winegrape Growers filed a petition with TTB proposing - changes to require wine labeled with an American appellation of origin to made entirely with American wine and for wines made from blends o
