Water Quality Testing

The City of Bend Water Quality Laboratory is part of the Utility Department's Environmental Services Division, whose purpose is to help the City plan for and respond to public health and environmental issues.

The Water Quality Laboratory (WQL) provides City staff with the high quality data they need to make informed decisions and maintain regulatory compliance.

Laboratory Accreditations

NELAP LogoThe lab is accredited by the Oregon Environmental Laboratory Accreditation Program (ORELAP), National Environmental Laboratory Accreditation Program (NELAP) and the Oregon Health Authority to perform analyses under the regulations administered by these agencies. Laboratory staff is experienced in a wide range of sampling and testing methods for both water and solids. Staff members have college degrees in chemistry, biology, microbiology or environmental science and all have years of experience with environmental testing in government and private sector laboratories.


Among the analyses routinely performed are bacterial testing (total coliforms, fecal coliforms, E.coli), nutrients, and conventional chemical and physical parameters (pH, BOD, TSS, etc…), and bacterial testing.

All testing is done using approved methods of analysis. Procedures are documented through Standard Operating Procedures and the Laboratory's Quality Assurance Manual. All data is reviewed by the Quality Assurance Officer and entered into the Laboratory Information Management System (LIMS) to ensure that data will always be safe and readily available for future reference.


We provide testing and analyses for several City of Bend Utility divisions, including the Water Reclamation Facility (WRF), Water Division, Stormwater Management Program, Biosolids Management and the Engineering Department.
