Well 34 and Well 19 Wellhead Treatment Project (Project)

The Project involves upgrading the water treatment systems at Well 34 and Well 19 to address contamination from 1,2,3-TCP and nitrate to meet regulatory standards. Key components include excavation, installation of approximately 10,586 square feet of concrete pads, four granular activated carbon vessels for 1,2,3-TCP removal, two ion exchange structures for nitrate reduction, six aboveground storage tanks for brine and waste, reconfiguration of well discharge piping, enhanced site lighting, and soil backfilling to restore ground levels. Each treatment train is designed to process 1,000 gallons per minute, with the concrete infrastructure预留 for a potential third train to extend treatment capacity to Well 19. The project will disturb about 0.87 acres of the 1.38-acre site without expanding the permitted water production capacity from either well. All improvements aim to ensure contaminant levels remain within established maximum contaminant levels. The California State Water Resources Control Board’s Division of Drinking Water is administering the project through its Montclair office, with Hector Cazares, District Engineer, serving as the primary point of contact for inquiries. Justin Scott-Coe, General Manager of MVWD, is listed as an additional contact. The project was posted as a forecast on August 4, 2026, with no set-aside or NAICS code specified. The scope excludes any increase in water extraction from the wells, focusing exclusively on treatment enhancements to protect public health and comply with drinking water standards.
