Water Quality Labs

Oklahoma State University has long had a strong water quality program. As our program continues to grow and evolve, so do the collaborative opportunities. Benefits of such collaboration include sharing knowledge and equipment; reducing expenditures for additional equipment and staffing requirements; providing additional laboratory training opportunities for faculty, staff, and students; and saving analysis costs.
