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).

Pathogenic Enterobacteria. The majority of the bacterial species belonging to this family are pathogenic only in certain situations. While E.coli are normal and welcomed occupants of the intestinal flora, they can cause urinary tract infections if allowed to spread beyond the confines of the intestinal tract.nterobacteria, Enteric Bacteria. The Enterobacteriaceae are the most common group of gram-negative rods and along with staphylococci and streptococci are among the most common bacteria that cause disease.
