Figure 1: Location of the Edwards Aquifer in relation to the Balcones fault zone and other physiographic features. Note how the aquifer cuts across the surface drainage basins. Figure 3: Topography and rainfall of the central segment of the Edwards Aquifer (modified from Woodruff and Abbott, 1979).he dominant geologic feature in the region is the Balcones fault zone, a system of en echelon, mainly down-to-the-coast, normal faults that extend about 545 km from Del Rio on the Mexican border to near Waco in north-central Texas.
CRE are bacteria that are resistant to most antibiotics due to the production of an enzyme called carbapenemase. Enterobacteriaceae is a family of bacteria and many of these bacteria live in our environment (such as soil or water).Some of them can get into our bodies and cause pneumonia, kidney and bladder infections, and bloodstream infections.nterobacteriaceae is a family of bacteria and many of these bacteria live in our environment (such as soil or water).

Several Enterobacteriaceae strains have been isolated which are resistant to antibiotics including carbapenem, which are often claimed as the last line of antibiotic defense against resistant organisms. For instance, some Klebsiella pneumoniae strains are carbapenem resistant.ost members of Enterobacteriaceae have peritrichous, type I fimbriae involved in the adhesion of the bacterial cells to their hosts. Some enterobacteria produce endotoxins. Endotoxins reside in the cell cytoplasm and are released when the cell dies and the cell wall disintegrates.
