point north of McWane Road, just beyond the City of Oxnard Barricades. Station AIR5 was
located due north of the eastern side of the WMU approximately 0.25 miles from the WMU. An
additional air sampler (Station AIR6) was used to provide a co-located station near AIR2. The
locations are presented in Figure 3-5.
On the night of June 22, three generators, the meteorological station and four of the high-volume
air pumps were stolen. WESTON® continued to collect data for stations AIR1 and AIR2 until
three new pumps arrived on June 27. Meteorological data were obtained from the Oxnard
Airport National Oceanographic and Atmospheric Administration (NOAA) office data.
3.1.5 Fish Tissue Samples
The EPA tasked WESTON® to collect fish tissue samples. The SOP used to collect the fish is
presented in Appendix G. WESTON® collected nine fish tissue samples from various locations
within the OID and in the adjacent lagoon using nets and fish traps.
There are nine samples, each representing species, size, and areas within the lagoon where the
fish were caught. Individual fish were bulked in order to meet the minimum/ideal weight
requirements for the metals and gross alpha/gamma analyses. Each sample was divided into two
subequal aliquots, one for metals, and one for gross alpha/gamma. Sample number eight was
inadvertently skipped. The locations, species, and sizes (where applicable) for each sample are:
• FISH1- eight topsmelt, greater than 4" in length, collected from the mouth of the OID.
• FISH2 - approximately 40 topsmelt (1 - 4") collected from the mouth of the OID.
• FISH3 - six long-jawed mudsuckers from the mouth of the OID.
• FISH4 - five large topsmelt collected from the outer industrial drain (beyond OID mouth).
• FISH5 - fifteen staghorn sculpin collected from the outer industrial drain (beyond OID
mouth).
• FISH6 - approximately 690 grams of small topsmelt collected 50 meters downstream of
the bridge in OID.
• FISH7 - 16 Topsmelt from the Fish Kill location at the extreme south end of the lagoon.
• FISH9 - 3 killifish collected from outer industrial drain (beyond OID mouth).
• FISH10 - 3 Long-jawed mudsuckers collected near the bridge in the OID.
