Summary |
The Edwards Aquifer, world renowned for its bio diversity, provides habitat to a variety of subterranean aquatic species ranging from blind salamanders to eyeless catfishes to ghost white shrimp. This report describes the results of a study of aquatic animals that reside in the deep zones of the Edwards Aquifer, primarily near the fresh water/saline water interface. Through cooperation with landowners across five counties, biologists from Zara Environmental Inc., sampled 43 wells between 2008 and 2010 for aquifer organisms. Highlights of the study include:
In addition, biologists obtained samples that will be used for organic carbon analyses and stable isotope analyses by other researchers. They also developed an in-line sampler design for situations where water delivery from well casing to outlet is in an entirely closed system. |
