The Chemists and Technicians perform a variety of physical, chemical, and bacteriological tests on environmental samples such as drinking water, wastewater, sludge, industrial wastewater, reclaimed water, and storm water as necessary for process control and regulatory permit parameter compliance. The Chemists and Technicians collect samples for analyses, analyze data and submit regulatory reports to the EPA, State of California Health Department/State Water Resources Control Board. The lab reports daily to the Operators to assist with optimizing the HARRF treatment process.  The HARRF Laboratory is certified by the State of California Environmental Laboratory Accreditation Program, ELAP.

 

 

 

 

 

 

About the Water Quality Laboratory

Introduction to the HARRF Water Quality Laboratory

The City of Escondido owns and operates a state-of-the-art water quality laboratory located at the Hale Avenue Resource Recovery Facility (HARRF). The Laboratory is staffed with Chemists, Microbiologists and Laboratory Technicians who analyze samples of Wastewater, Drinking Water, Recycled Water, Biosolids, Well Water, Industrial Waste, Storm Water and Escondido Creek Water throughout the City of Escondido for regulatory purposes. The 5,000 sq. foot Laboratory is certified by the State of California Environmental Laboratory Accreditation Program (ELAP) to analyze samples for regulatory purposes and goes through a stringent audit process every two years to maintain State of California ELAP Certification. The laboratory is also compliant with The Nelac Institute (TNI), laboratory accreditation standards. In addition to assisting the wastewater reclamation facility operators with laboratory data and information to help run the HARRF plant efficiently, the laboratory staff takes samples and runs tests on drinking water from the Escondido Vista Water Treatment Plant and distribution system throughout the City. The laboratory provides data for the water treatment plant operators and the water distribution technicians to ensure our drinking water is safe and meets all Federal and State Drinking Water Standards.
