PCB Profiles
< Sediment contamination in San Leandro Bay, California
A study was conducted in 1998 to assess the extent of sediment contamination in
the San Leandro Bay, which is a shallow embayment located south of Alameda Island
on the east side of the San Francisco Bay. Sediment samples from 60 sites located
throughout San Leandro Bay and four tributaries were collected and analyzed for
trace metals, PCBs, polycyclic aromatic hydrocarbons (PAHs), and various synthetic
biocides. The general goal of the study was to evaluate the distribution of sediment
contamination and identify possible sources and pathways of contamination to San
Leandro Bay PCB concentrations in San Leandro Bay sediment were adapted for use in this
study from the following report:
Methods of quality assurance/quality control for sample collection and analysis were similar to methods used by the RMP. PCB concentrations represent the sum of 36 individual PCB congeners routinely measured by the RMP. |
