Figure F59. Downhole variations in percentage contamination in interstitial water (IW) as determined from perfluorocarbon (PFC) concentrations in cores and liquid in core liner (LCL) fluids. The only IW core with significant contamination is from Section 348-C0002P-2R-3. PFC in LCL from Core 1R was 56 µg/L, but no IW sample was taken from this core.
