4.6.1.2 Sampling locations
Grab samples will be collected at the following sites for use in laboratory bioassays:
Site B - SLD at new bridge
Site C - Mud Slough upstream of SLD discharge
Site D - Mud Slough downstream of SLD discharge
Site F - Salt Slough at Highway 165
Control - Delta-Mendota Canal
Rationale for the selection of these sites have been previously described.
Samples from all sites except Site B have been used in two pre-project toxicity test events (December 95, February 96). Station B will not be sampled for toxicity testing until after the GBP is initiated. The rationale for the selection of these sites has been described elsewhere. The Delta-Mendota Canal (DMC) site was selected as a control site because it is the nearest freshwater source to the project area. The DMC water is considered to be of good quality which can be used as a dilution water in the event that definitive bioassays are required.
