Acid mine drainage - Wikipedia
Water temperatures as high as 47 C  have been measured underground at the Iron Mountain Mine, and the pH can be as low as -3.6.  Organisms which cause acid mine drainage can thrive in waters with pH very close to zero. Negative pH  occurs when water evaporates from already acidic pools thereby increasing the concentration of hydrogen ions.
