2017 Water Emergency: Laboratory Results of Water Samples

In February 2017, a series of events led to a large-scale water emergency in our community, resulting in Do-Not-Use and Do-Not-Drink directives for the entire service area that remained in effect for over a day. These directives were required to protect public health and the water supply. OWASA collected and analyzed water samples from across the distribution system to confirm the safety of the community's drinking water.  The results of these analyses informed decision-making throughout the emergency. 

Laboratory results of samples taken from OWASA Drinking Water Distribution System throughout the emergency

  • Fluoride (Samples collected February 2-5, 2017)
  • E. coli (Samples collected February 3-5, 2017)
  • pH (Samples collected February 3-5, 2017)
  • Total Chlorine (Samples collected February 3-5, 2017
  • Total Coliform (Samples collected February 3-5, 2017)
  • Turbidity (Samples collected February 3-5, 2017)
