Well Water Testing


In rural Lane County, a water source may be a spring, river water, shallow or deep well. Water quality can vary greatly depending on both the source and the local conditions. 

Surface water is naturally pure in our area but is easily subject to contamination by animals and people. The most common contaminants can be treated using filtration, UV, or chlorination. Other water quality issues may include tannin, which color the water, gas bubbles, and hydrogen sulfide (rotten egg smell).

  • Coliform
  • e.Coli
  • Arsenic
  • Iron
  • Nitrates
  • Silica

Other Common Issues in Oregon:

  • Hard Water
  • Low pH
  • High pH
