Aquifer Systems Serving Los Angeles

Los Angeles groundwater comes from several aquifer systems. Understanding which aquifers are present in your specific area helps assess feasibility, depth, and cost:

• Los Angeles Basin Aquifer
• Central Valley Aquifer (northern parts)
• Coastal aquifer systems

Each aquifer system has different characteristics regarding depth, water quality, productivity, and regulatory requirements. A local well contractor can assess which aquifer your property can access and at what depth.

Water Quality Considerations

Water Quality Profile: Varies widely by location; coastal areas at risk of saltwater intrusion

Water quality varies by location within Los Angeles. Areas near the Los Angeles Basin Aquifer often have excellent groundwater, while other locations may need treatment for hardness, iron, or other contaminants. Initial water testing after drilling identifies any quality issues requiring treatment systems.
