Can this water be used as a drinking-water supply?

A use the state didn't report is omitted rather than shown as passing. "Never assessed" means unknown — never clean.

Listed causes

  • benthic macroinvertebrates bioassessments (cause unknown - impaired biota)
  • fecal coliform (pathogens)
  • escherichia coli (e. coli) (pathogens)
  • temperature

A listed cause names what the assessment found in the water. It is not an attribution to any specific facility or source.
