Cross Section of Fruitvale and Rosedale Ranch Groundwater Salinity
This cross-section was used in this study which modeled subsurface salinity in the vicinity of Fruitvale and Rosedale Ranch oil fields.
Some key findings:
- Thickness and depth of fresh and brackish groundwater varies across these oil fields.
- Salinities vary within the Chanac formation from 5,000 to about 30,000 ppm TDS.
- This variation is systematic.
- Variation is caused by (1) clay layer thickness, (2) distance from a major freshwater recharge source, and (3) faults.
