II. Update on the Development of a Basin Management Action Plan (BMAP) for Wagner Creek – Mr. Omar Abdelrahman, Miami-Dade Department of Environmental Resources Management (DERM), noted he and Ms. Diane Waters, City of Miami Public Works Department, had recently participated in a conference call with representatives of The Florida Department of Environmental Protection (FDEP) to commence the process of creating the Wagner Creek BMAP. Mr. Bibeau asked if the Wagner Creek BMAP seeks to identify and create a plan to eliminate pollutant source(s), and Ms. Waters replied that the intent of the BMAP is to identify the source of pollutants. Mr. Bibeau asked if the BMAP would outline a plan to eliminate any determined source(s) of pollutants into Wagner Creek, and Mr. Abdelrahman replied that the BMAP may incorporate such recommendations. Mr. Bibeau asked for the timeline to complete the BMAP, and Ms. Waters replied that FDEP had yet to set a timeline, and agreed to follow up with that information. Mr. Abdelrahman stated DERM had recently taken water quality samples for fecal coliform, total coliform and e-coli, from the Wagner Creek headwaters in Comstock Park , and his preliminary review of the small data set does not indicate a pollutant source, and noted most of the samples were actually beneath the County standards. Mr. Abdelrahman stated he would like to take additional samples from other areas of the Wagner Creek headwaters, north of NW 20 ST. IV. Discussion of Alternative Methods for Pollutant Source Tracking – According to Mr. Abdelrahman, Mr. Fred Calder, FDEP, revealed that field experts do not consider DNA/bacteriological source tracking an effective or useful methodology for water quality determinations. Ms. Waters added that genetic testing may or may not be able to determine the source of pollutants and Mr. Abdelrahman replied that Smoke Testing doesn't guarantee discovering pollutant sources either. Mr. Hand stated the environmental agencies should continue efforts to determine and eliminate the long standing Wagner Creek pollutant sources. Mr. Hand noted especially considering the City of Miami is investing millions in tax payer funds to dredge the Wagner Creek and Seybold Canal , it is critical to identify and eliminate the water bodies pollutant sources. Mr. Hand provided an article featured in Surfrider Magazine, entitled “Water Quality Issues,” which illustrates the use of different source tracking methods, such as DNA testing, to successfully identify and institute programs to identify the sources of fecal coliform, e.coli, and other forms of pollution. Mr. Hand noted that a study of the Tualatin River Basin in Oregon revealed that duck waste was responsible for approximately 50% of the pollution. Mr. Hand noted that the population of ducks around his neighborhood has grown dramatically, and suggested that perhaps they may be contributing to the increasing levels of coliform and fecal matter. Considering FDEP's reluctance to conduct DNA testing along Wagner Creek and Seybold Canal , Mr. Hand suggested performing alternative forms of testing to identify main pollutant factors, and eventually narrow them down to a possible source of fecal coliform. Ms. Dianne Waters, City of Miami Public Works Department provided examples of alternative testing methodologies:
Ms. Perez asked Ms. Waters if she had a document illustrating different types of testing methods, and their projected costs, and Ms. Waters replied she would try to find out if the city had such a document available. Mr. Abdelrahman noted that smoke testing and sampling have thus far been the only testing methods, which have not identified any major pollutant sources. Mr. Bibeau noted the grant opportunities MRC staff provided the City and County, which if applied for and awarded may provide funding, and thanked the City and County for their continued efforts. Mr. Abdelrahman offered to discuss with his supervisor the possibility of contacting FDEP - to request a teleconference call with the MRC SSC - to determine why they are opposed to conducting DNA molecular source tracking, as well as identify alternative methodologies. IV. New Business- The following items were addresses/discussed:
The SSC confirmed its next publicly noticed meeting for Wednesday, November 7, 2007 , 10 am, Miami River Inn, 118 South River Drive . The meeting adjourned. |
