Alkalinity refers to how well a water body can neutralize acids.
These compounds are natural buffers that can remove excess hydrogen ions that have been added from sources such as acid rain or acid mine drainage. The Boulder Creek Watershed is composed primarily of granite rocks, thus the water has a lower alkalinity content. 1.0 Preliminary Data - subject to revision Select on the parameter name to view all Total Alkalinity time series plots on the basin map.
