Public Water Supply Health Notices

Lake County Public Works will initiate a Public Notice if certain contaminants in the drinking water system are found to be higher than the set standards.  Occurrences are rare, but might be caused by:

  • Changes in local source water conditions
  • Heavy rainstorms
  • Changes in the condition of the distribution system

Public Health Notices currently in effect for Lake County Public Works water systems:


Hydrant Flushing
We routinely flush our water mains through nearby fire hydrants in order to clean out sediments and maintain chlorine in the system for disinfection.
