Figure 9. Graph of total dissolved solids (TDS) versus depth of geochemical samples from the Tulare Formation in and near the North and South Belridge oil fields. The northern and southern parts of the South Belridge field (marked by the red line on the map) are shown in separate graphs. Blue dots show Tulare Formation (Fm.). Measurements of TDS from lab analyses. Gray dots show Tulare Fm. The TDS calculated from log analysis. Horizontal red lines on the graphs mark 10,000 mg/L and the dashed vertical red lines mark the approximate depth of USDW from lab samples. The adjacent map shows the location of the wells sampled (blue dots) and the contours to base underground sources of drinking water (USDW) (in feet) from log analysis. Black lines are oil field administrative boundaries, and red lines are faults. C.I. = contour interval; No. = North; So. = South.
