 | | The Comal Springs riffle beetle lacks the ability to fly that many other riffle beetles have, suggesting that it is adapted to continuous and reliable spring flows (although flow may still be variable). |
 | | Fern Bank Springs is in a relatively remote, rural location and its principal vulnerability is probably to contaminants associated with leaking septic tanks, animal/ feedlot wastes, and agricultural chemicals. |
 | | Of the counties containing portions of the San Antonio segment of the Edwards Aquifer, the potential for acute, catastrophic contamination of the aquifer is greatest in Bexar, Hays, and Comal counties because of the greater level of urbanization compared to the western counties. |
