In order to ensure the health and safety of students, faculty, staff, and visitors, drinking water sources are monitored for water quality. Oregon State University’s Environmental Health and Safety (EH&S) department tests for a variety of contaminants on both a routine basis and in response to concerns that may be reported. The focus of the program is to sample all drinking water sources for lead concentration. Lead in drinking water may be a concern at high levels due to negative health effects, especially for children or if pregnant.

Interpreting Results

The EPA action level for lead is 0.015 mg/L or 15 ppb. Drinking water samples that meet or exceed the action level will be resampled. If they remain at or above the action level, the fixture will be repaired by Facilities Services or another department responsible for fixture maintenance. If water samples from the fixtures are below 0.015 mg/L, they will be considered in compliance and no further action will be taken.

Various Water Sources 

  • Potable: Fixtures that are served by a potable source and a designated potable distribution system, are considered potable.
  • Industrial: Industrial water is any water source that has been separated from the potable distribution system via an approved backflow prevention device. Industrial water is most commonly found in laboratories and is not suitable for drinking. OSU EH&S has been placing stickers on industrial water sources outside of labs. These stickers are available upon request.
  • Well Water: If a water system is sourced from a well or other nonpublic source, additional testing can be requested to ensure safe consumption.
