The Water Quality Laboratory was built adjacent to Regional Water Recycling Plant No. 5 (RP-5) in Chino to manage water quality testing, enhance performance and improve the process of sample analysis. The 17,166 square foot, $17.8 million Water Quality laboratory is a Gold LEED™ Certified building for its energy efficiency and the use of eco-friendly materials. The Laboratory supports the analytical needs of the Agency’s five wastewater reclamation plants and the Groundwater Recharge Program with approximately 18,000 samples collected and 64,000 various tests conducted each year. The Water Quality Laboratory supports NPDES and California Division of Drinking Water permit compliance monitoring, as well as industrial and domestic wastewater discharge monitoring for the Agency’s Pre-Treatment and Source Control Department.

To meet regulations set by the Clean Water Act program, the lab utilizes extractions, gas chromatography, metals analysis, bioassays, and wet chemical analysis to assess environmental impacts the recycled water will have on aquatic organisms when discharged into nearby bodies of water, and to test for pollutants, metals and total coliform.

The new facility is equipped to provide support to the Agency’s Chino Desalter I facility and well-monitoring for IEUA’s member agencies.
