| Otay Formation | 50-300 ft | Sandstone/conglomerate, primary aquifer |
| San Diego Formation | 200-500+ ft | Marine sediments, secondary aquifer |
Water Quality
The Otay area groundwater has variable quality:
- TDS: 500-2,000 mg/L (varies by zone)
- Hardness: Moderate to hard
- Iron: Sometimes elevated
- Irrigation use: Generally suitable
- Potable use: May require treatment depending on zone
Commercial Well Drilling
Otay Mesa's industrial zone is one of San Diego County's best areas for commercial well development.
Industrial Applications
